**Vishay Intertech** · Electrostatic And Surge Protection (TVS/ESD) · SMB(DO-214AA)

SMBJ60A-E3 from Vishay Intertech, in a SMB(DO-214AA). 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 SMBJ60A, marked by the cathode band on the package, with 60 V stand-off voltage (VWM) and 66.7 V to 73.7 V breakdown voltage at 1.0 mA. |
| 2 | Anode | passive | Anode terminal of the unidirectional SMBJ60A, opposite the cathode band, with a maximum clamping voltage of 96.8 V at 6.2 A peak pulse current. |
