LPM3406B3F

LOWPOWER · MOSFETs · SOT-23

LPM3406B3F from LOWPOWER, 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 MOSFET, used to switch the device (VGS limits are ±20 V per the absolute maximum ratings, not pin-specific).
2 Source passive Source terminal of the N-channel MOSFET, serving as the reference for the gate drive; the datasheet gives no pin-specific limit for this pin.
3 Drain passive Drain terminal of the N-channel MOSFET, carrying the switched current (VDS 30 V and continuous ID 3.6 A at TA=25℃ per the absolute maximum ratings, not pin-specific).
