KYL3407

KY · MOSFETs · SOT-23-3L

KYL3407 from KY, in a SOT-23-3L. 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 P-channel MOSFET; the gate-source voltage is rated at ±20 V (absolute maximum, VGS).
2 SOURCE passive Source terminal of the P-channel MOSFET; the datasheet gives no separate pin-level limit beyond the device absolute maximum ratings.
3 DRAIN passive Drain terminal of the P-channel MOSFET; the drain-source voltage is rated at -30 V (absolute maximum, VDS) with continuous drain current of -3.8 A.
