**TWGMC** · ESD And Surge Protection (TVS/ESD) · DO-214AB(SMC)

SMCJ130A from TWGMC, in a DO-214AB(SMC). 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 of the unidirectional SMCJ130A transient voltage suppressor, which has a reverse stand-off voltage (VRWM) of 130 V and a maximum clamping voltage of 209 V at 7.2 A peak pulse current. |
| 2 | Anode | passive | Anode of the unidirectional SMCJ130A, which is the terminal opposite the cathode in the unipolar configuration shown in the datasheet pinning table. |
