BSS138W-7-F

Diodes Incorporated · MOSFETs · SOT-323

BSS138W-7-F from Diodes Incorporated, in a SOT-323. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Gate input Control terminal with 0-20V continuous gate-source voltage rating and gate threshold voltage of 0.5-1.5V at VDS=VGS and ID=250µA.
2 Source power_in Reference terminal for gate-source voltage control, typically grounded in load switch and power management applications.
3 Drain tri_state Drain terminal rated for 200mA maximum continuous current at 50V maximum drain-source voltage with on-resistance of 3.5Ω maximum at VGS=10V.
