PJM123NSA

PJSEMI · MOSFETs · SOT-23

PJM123NSA from PJSEMI, in a SOT-23. 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 of the N-channel enhancement MOSFET; the absolute maximum gate-source voltage is ±20 V (VGS).
2 Source passive Source terminal of the MOSFET; the source-drain diode is rated for a continuous source current IS of 0.17 A maximum with a forward voltage VSD of 1.3 V maximum at VGS = 0 V, IS = 0.34 A.
3 Drain passive Drain terminal of the MOSFET; the absolute maximum drain-source voltage is 100 V (VDS) and the continuous drain current is 0.17 A (ID) at TC = 25 ℃.
