# PEC3836C2A-AU_R1_000A1

**PANJIT International** · ESD And Surge Protection (TVS/ESD) · SOT-23

PEC3836C2A-AU_R1_000A1 from PANJIT International, 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 | IO1 | passive | Protected I/O line 1, clamped to pin 3 by a TVS diode with 36 V reverse stand-off (VRWM) and 37.5-52.5 V breakdown at 1 mA for the PEC3836C2A-AU. |
| 2 | IO2 | passive | Protected I/O line 2, clamped to pin 3 by a TVS diode with 36 V reverse stand-off (VRWM) and 37.5-52.5 V breakdown at 1 mA for the PEC3836C2A-AU. |
| 3 | GND | power_in | Common ground pin shared by both TVS diodes, which the datasheet's IO-GND curves reference. |
