**Diodes Incorporated** · ESD And Surge Protection (TVS/ESD) · SMA

SMAJ70A-13-F from Diodes Incorporated, in a SMA. 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 | K | passive | Cathode, the terminal marked by the cathode band on the unidirectional SMAJ70A; it connects to the positive side of the protected line, with VRWM 70V, VBR 77.8-86.0V at 1.0mA and VC 113V at 3.5A. |
| 2 | A | passive | Anode, the terminal opposite the cathode band on the unidirectional SMAJ70A, normally connected to ground or the return of the protected line. |
