Detailed parameter description:
1. **VDS (drain-source voltage)**: 900V
- STW7NK90Z-VB has a maximum drain-source voltage of 900V, which is suitable for high-voltage power electronic equipment, can withstand higher operating voltages, and adapt to the requirements in power systems.
2. **VGS (gate-source voltage)**: ±30V
- The maximum gate-source voltage is ±30V, supporting the common gate drive voltage range, suitable for compatibility with various drive circuits, and ensuring reliable switching control.
3. **Vth (threshold voltage)**: 3.5V
- The threshold voltage is 3.5V. When the gate-source voltage is higher than this threshold, the MOSFET starts to turn on. The moderate threshold voltage enables it to work stably under standard power drive.
