YJL3404B

Yangzhou Yangjie Elec Tech · MOSFETs · SOT-23(TO-236)

YJL3404B from Yangzhou Yangjie Elec Tech, in a SOT-23(TO-236). 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 G input Gate; the gate-source voltage is rated at ±20 V maximum, with a typical threshold of 1.6 V (1 V min, 2.2 V max) at ID=250μA.
2 S passive Source; the continuous body-diode current is rated at 5.6 A maximum, and VSD is 1.2 V maximum at IS=5.6A.
3 D passive Drain; VDS is rated at 30 V maximum and the continuous drain current is 5.6 A at TA=25℃, with a pulsed rating of 40 A.
