CORE PRODUCT SCOPE
MOSFETs
Power MOSFETs are widely used power switching devices for efficient control and conversion of electrical energy. This category includes low-voltage, medium-voltage and high-voltage MOSFETs for switching power supplies, DC-DC converters, motor drives, battery systems, solar inverters, UPS equipment and industrial power conversion. Key selection factors include voltage rating, drain current, RDS(on), switching performance, package and thermal conditions. SemiVant supports sourcing for standard, replacement, long-lead-time, EOL and hard-to-find MOSFETs based on the actual application requirements.
IGBT Discretes & Modules
IGBT Discretes & Modules include discrete IGBTs, half-bridge modules, six-pack modules, dual IGBT modules and other industrial power module configurations. IGBTs are designed for high-voltage and high-current switching in industrial drives, UPS systems, solar inverters, energy storage PCS, welding equipment, induction heating and industrial power supplies. Selection requires reviewing voltage and current ratings, switching parameters, package, terminals, thermal performance and mechanical compatibility. SemiVant supports replacement, EOL and multi-part BOM sourcing.
IPM Modules
IPM Modules integrate power switching devices, gate drivers and protection circuits into a single intelligent power module. Depending on the product family, an IPM may include IGBTs, MOSFETs, freewheeling diodes, short-circuit protection, over-current protection, under-voltage lockout and temperature monitoring. IPMs are commonly used in motor drives, servo systems, inverters, pumps, fans and industrial automation equipment. SemiVant supports sourcing according to motor voltage, current rating, control interface, switching frequency, package, pin configuration and replacement requirements.
SiC Power Devices
SiC Power Devices include SiC Schottky diodes, SiC MOSFETs, SiC JFETs, cascode devices and SiC power modules. As wide-bandgap semiconductors, they support high-efficiency, high-frequency and high-temperature power conversion with reduced switching losses. Typical applications include solar inverters, EV chargers, energy storage systems, industrial power supplies, high-frequency converters and electric vehicle powertrains. Selection should consider blocking voltage, current rating, switching performance, gate-drive requirements, package, thermal conditions and system-level compatibility.
Diodes & Rectifiers
Diodes & Rectifiers include standard rectifier diodes, fast-recovery diodes, ultrafast diodes, Schottky diodes, bridge rectifiers, power recovery diodes and high-current rectifier assemblies. They control current direction and convert AC power into DC power in power supplies, inverter circuits, battery chargers, industrial converters, motor drives, welding machines and UPS systems. Important selection factors include reverse voltage, average forward current, surge current, reverse-recovery time, forward voltage and thermal performance. SemiVant supports replacement, repair and hard-to-find sourcing.
Thyristors
Thyristors include SCRs, TRIACs, fast thyristors and phase-control thyristors for controlled rectification, AC power control and high-power switching. They are widely used in soft starters, industrial heating systems, welding equipment, controlled rectifiers, motor speed control, battery chargers and AC voltage regulators. Selection usually depends on repetitive peak off-state voltage, average on-state current, surge current, gate trigger requirements, commutation characteristics, package and thermal conditions. SemiVant supports replacement and hard-to-find thyristor sourcing.
IGCTs
IGCTs, or Integrated Gate-Commutated Thyristors, are high-power semiconductor switching devices for medium-voltage and high-power conversion systems. They combine a low-loss thyristor structure with an integrated gate unit for rapid turn-off control. IGCTs are used in medium-voltage drives, large industrial inverters, power quality systems, rolling mills, pumps, compressors and other demanding applications. Selection involves voltage class, current rating, gate-unit compatibility, press-pack structure, cooling method, application topology and replacement requirements.
IEGTs (PPT)
IEGTs and press-pack transistor devices are high-power switching components for demanding industrial and utility-scale power conversion systems. They are designed for high-voltage, high-current operation in high-power inverters, traction systems, utility converters, renewable-energy infrastructure and industrial drives. Selection requires more than matching voltage and current; gate drive, clamping force, cooling method, mechanical dimensions and system topology must also be reviewed. SemiVant supports sourcing for replacement references, EOL components and project-specific procurement requirements.
Power Management ICs
Power Management ICs include LDO regulators, DC-DC converters, PWM controllers, AC-DC controllers, PFC controllers, battery-management ICs, voltage supervisors and power monitoring devices. These ICs regulate and distribute power, control startup and shutdown sequences, improve conversion efficiency and protect electronic circuits. They are used in industrial power supplies, control systems, embedded equipment, communication systems, battery systems and power conversion platforms. SemiVant supports sourcing according to input and output voltage, current capability, topology, switching frequency, package and protection functions.
Gate Drivers & Isolation
Gate Drivers & Isolation Components include MOSFET gate drivers, IGBT drivers, isolated gate drivers, optocouplers, digital isolators and isolated DC-DC driver supplies. They control the turn-on and turn-off behavior of power switches while separating low-voltage control circuits from high-voltage power stages. Proper selection affects switching speed, switching loss, electromagnetic interference, dead time and protection response. SemiVant supports sourcing based on drive voltage, output current, isolation rating, propagation delay, common-mode transient immunity, package and channel configuration.
Power Passive Components
Power Passive Components include DC-link film capacitors, electrolytic capacitors, power resistors, braking resistors, current-sense resistors, inductors, chokes, transformers and EMI-filter components. These parts store energy, limit current, filter voltage ripple, absorb switching energy and support stable operation of power stages. They are widely used in inverters, UPS systems, industrial drives, solar systems, energy storage PCS, EV chargers and industrial power supplies. SemiVant supports sourcing according to capacitance, voltage rating, ripple current, ESR, pulse capability, resistance, inductance, dimensions and thermal conditions.
EOL & Hard-to-Find Parts
EOL & Hard-to-Find Parts support covers obsolete, discontinued, NRND, allocated, long-lead-time and difficult-to-source power semiconductor components. This may include MOSFETs, IGBTs, power modules, rectifiers, thyristors, IPMs, gate drivers, PMICs and related passive components. These parts are often required for equipment repair, installed-base maintenance, legacy product support, small-batch production and urgent replacement projects. SemiVant can help review original part numbers, identify possible replacement references and compare electrical, mechanical, packaging and traceability requirements.
