# HPJSRV05-4-AU

**HXY MOSFET** · Electrostatic And Surge Protection (TVS/ESD) · SOT-23-6L

HPJSRV05-4-AU from HXY MOSFET, in a SOT-23-6L. 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 | ESD-protected I/O channel clamped to the rails by a diode pair, with 0.4pF max capacitance to GND and VRWM of 5V max. |
| 2 | GND | power_in | Negative rail pin connected to system ground, to which positive ESD current is steered through an ESD diode and the zener diode. |
| 3 | I/O2 | passive | ESD-protected I/O channel clamped to the rails by a diode pair, with 0.4pF max capacitance to GND and VRWM of 5V max. |
| 4 | I/O3 | passive | ESD-protected I/O channel clamped to the rails by a diode pair, with 0.4pF max capacitance to GND and VRWM of 5V max. |
| 5 | VCC | power_in | Positive rail pin with an integrated zener diode to GND that sets the positive clamping voltage, with a reverse breakdown voltage of 6V min. |
| 6 | I/O4 | passive | ESD-protected I/O channel clamped to the rails by a diode pair, with 0.4pF max capacitance to GND and VRWM of 5V max. |
