BSS84

Diodes Incorporated · MOSFET · SOT-23

The BSS84 is a P-channel enhancement-mode MOSFET rated for -50 V and about -130 mA in a SOT-23 package. It is used for high-side load switching, reverse-polarity protection, and level shifting, and is the P-channel complement of the N-channel BSS138.

Pinout

Pin Name Type Function
1 G input Gate. Enhancement-mode P-channel control terminal. VGS(TH) between -0.8V and -2.0V; drive to -5V or more negative (up to ±20V max VGSS) to fully enhance the channel.
2 S passive Source. Reference terminal for VGS. Body diode anode connects internally to source (P-channel body diode from drain to source).
3 D passive Drain. Switched terminal. -50V max VDSS; -130mA continuous ID, -1.2A pulsed IDM. RDS(ON) typ 3.2Ω / 10Ω max at VGS=-5V, ID=-100mA.
