# SDT23C712L02-ES

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

SDT23C712L02-ES from ElecSuper, 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 | IO | bidirectional | Connects to the protected IO line; for Pin1 to Pin3 the reverse stand-off voltage is 12.0 V, and the peak pulse current (tp=8/20us) is 17 A. |
| 2 | IO | bidirectional | Connects to the protected IO line; for Pin2 to Pin3 the reverse stand-off voltage is 12.0 V, and the peak pulse current (tp=8/20us) is 17 A. |
| 3 | GND | power_in | Connects to GND as the common reference for the protected IO lines; for Pin3 to Pin1 or Pin2 the reverse stand-off voltage is 7.0 V, and the peak pulse current is 22 A. |
