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

ES712D2HA23 from GOODWORK, 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 | PIN1 | passive | One bidirectional ESD-protected line terminal, rated with a 12 V reverse working voltage to PIN3, 14.2 to 16.2 V breakdown at 1 mA, 15 A peak pulse current and 24 V clamping at 15 A (8/20 µs). |
| 2 | PIN2 | passive | Second bidirectional ESD-protected line terminal, rated the same as PIN1 (12 V reverse working voltage to PIN3, 14.2 to 16.2 V breakdown at 1 mA, 15 A peak pulse current, 24 V clamping at 15 A) per the datasheet's PIN1/PIN2 grouping. |
| 3 | PIN3 | passive | Common terminal of the protection diode, rated with a 7 V reverse working voltage to PIN1/PIN2, 9.4 to 12.4 V breakdown at 1 mA, 20 A peak pulse current and 20 V clamping at 20 A (8/20 µs). |
