NSVBC857BLT3G-HXY

HXY MOSFET · Bipolar (BJT) · SOT-23

NSVBC857BLT3G-HXY from HXY MOSFET, 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 B input Base of the PNP transistor; the datasheet gives no base current rating, but specifies VEBO of -5 V and IEBO of -0.1 µA max at VEB = -5 V.
2 E passive Emitter of the PNP transistor; the emitter-base voltage is limited to -5 V.
3 C passive Collector of the PNP transistor; the datasheet rates it at IC = -0.1 A continuous, VCBO = -50 V and VCEO = -45 V.
