STGP3NC120HD

STGP3NC120HD is a high‑voltage N‑channel Power MOSFET from STMicroelectronics (STGP3N family). It targets demanding switching power applications such as switched‑mode power supplies, DC‑DC converters, PFC stages, motor drives, and inverters. Built with ST’s trench MOSFET technology, it delivers relatively low on‑resistance at high drain voltage, fast switching, and rugged protection (including avalanche/short‑circuit tolerance) for hard‑switching topologies. The “120” indicates a roughly 1.2 kV Vds rating, with current capability in the tens of amps depending on package and cooling. It is available in standard power packages and designed for reliable thermal performance and a solid safe‑operating‑area (SOA). For exact specs (Rds(on), Id, Qgs/Qgd, packaging, and thermal data), consult the official datasheet and ST application notes. If you want, I can pull the specific datasheet details.

STGP3NC120HD is a STMicroelectronics high‑density IGBT/diode power module used in motor drives/inverters. Key features (typical):
- 1200 V blocking voltage
- IGBT(s) with antiparallel diodes in a compact power-module package
- Fast switching capability with low on‑state voltage drop
- Integrated protection features (UVLO/overcurrent/overtemperature/fault latch)
- Isolated control-to-power interfaces and robust module isolation
- Suitable for PWM inverter applications; supports paralleling/stacking in multi‑phase drives
- RoHS compliant and lead‑free
- Wide operating temperature range (−40 °C to +125 °C typical)
Note: exact current rating per device and configuration depend on the specific module variant (single/double/three‑phase sectioning) within the STGP3N C120HD family. For precise specs, refer to the official datasheet.
