# NSVMMBT5401LT3G

**onsemi** · Bipolar (BJT) · SOT-23

NSVMMBT5401LT3G from onsemi, 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 | BASE | passive | Base terminal of the PNP transistor; the datasheet gives no base-only limit, and the device's absolute maximum ratings (VEBO −5.0 Vdc, IC −500 mAdc continuous) apply to this pin's operation. |
| 2 | EMITTER | passive | Emitter terminal of the PNP transistor, with emitter-base voltage limited to −5.0 Vdc (VEBO) and collector current limited to −500 mAdc continuous. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor, rated for −150 Vdc collector-emitter (VCEO) and −160 Vdc collector-base (VCBO), with −500 mAdc continuous collector current. |
