STMicroelectronics · MOSFETs · DPAK
STD5NK40ZT4 from STMicroelectronics, in a DPAK. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Gate | input | Gate terminal for MOSFET switching control with maximum gate-source voltage ±30V and integrated Zener diode protection. |
| 2 | Drain | passive | Drain terminal rated for maximum 400V drain-source voltage; connected to case tab for thermal dissipation path. |
| 3 | Source | power_in | Source terminal providing reference potential for gate and drain voltages; typical return path connection. |
