**JSMSEMI** · MOSFETs · TO-220AB

IRF9Z34NPBF-JSM from JSMSEMI, in a TO-220AB. 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 | G | input | Gate terminal of the P-channel MOSFET, with gate-source voltage VGS rated at ±20 V. |
| 2 | D | passive | Drain terminal of the P-channel MOSFET, rated for drain-source voltage VDSS of -60 V and drain current ID of -20 A at Tc=25℃. |
| 3 | S | passive | Source terminal of the P-channel MOSFET; the datasheet gives no source-specific rating beyond the device limits. |
