HSTS232050B751

HXY MOSFET · ESD And Surge Protection (TVS/ESD) · SOT-23

HSTS232050B751 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 I/O1 passive Protected line 1, connected through a TVS diode to common pin 3; the device protects one bidirectional line or two unidirectional lines with VRWM 3.3V max.
2 I/O2 passive Protected line 2, connected through a TVS diode to common pin 3; the device protects one bidirectional line or two unidirectional lines with VRWM 3.3V max.
3 COMMON passive Common node of the two TVS diodes shown in the circuit diagram, shared by pins 1 and 2.
