# PSD36C-ES

**ElecSuper** · ESD And Surge Protection (TVS/ESD) · SOD-323

PSD36C-ES from ElecSuper, in a SOD-323. 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 | bidirectional | Connects to the protected IO line of the single bi-directional line, with a rated reverse stand-off voltage (VRWM) of 36 V and ±30 kV IEC 61000-4-2 contact and air ESD protection. |
| 2 | IO2 | bidirectional | Connects to the protected IO line at the other end of the single bi-directional line, with the same 36 V working voltage and ±30 kV IEC 61000-4-2 ESD rating. |
