JSM502

JSMSEMI · Hall Switches · TO-92S

JSM502 from JSMSEMI, in a TO-92S. 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 VCC power_in Supply pin with a recommended range of 2.7 V to 30 V for 3-wire devices, an absolute maximum of 20 V for t < 1000 h, and built-in reverse-voltage protection at the Vcc pin.
2 GND power_in Ground reference pin; all voltages in the datasheet are referenced to ground (GND).
3 Vout output Open-drain output pin with a recommended maximum output voltage of 30 V and output current of 25 mA, an absolute maximum output current of 65 mA, and short-circuit current limiting.
