## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GATE | input | Gate terminal of the P-channel MOSFET; rated for a gate-source voltage of ±20 V, with gate threshold VGS(th) of −0.9 V to −2 V at VDS = VGS and ID = −250 µA. |
| 2 | SOURCE | passive | Source terminal of the P-channel MOSFET; the body diode forward voltage VSD is −2.2 V maximum at VGS = 0 V and IS = −0.13 A. |
| 3 | DRAIN | passive | Drain terminal of the P-channel MOSFET; rated for a drain-source voltage of −50 V (V(BR)DSS at VGS = 0 V, ID = −250 µA), with continuous drain current of −0.13 A and pulsed drain current of −0.52 A. |
