# PSD36-N

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

PSD36-N from BORN, 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 | Cathode | passive | Cathode terminal of the unidirectional ESD protection diode (240 W peak pulse power at tp = 8/20 µs, 36 V working peak reverse voltage); the datasheet gives no pin-specific limits beyond the device ratings. |
| 2 | Anode | passive | Anode terminal of the unidirectional ESD protection diode, with device-level ratings applying to this pin pair as stated in the absolute maximum and electrical parameter tables. |
