SMBJ110A-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, identified by the band on unidirectional types; for SMBJ110A the stand-off voltage VWM is 110 V and the breakdown VBR is 122 V min to 135 V max at 1.0 mA, with maximum clamping voltage VC of 177 V at IPPM 3.4 A. |
| 2 | Anode | passive | Anode terminal, the end opposite the cathode band on unidirectional types; the datasheet gives a forward voltage VF of 3.5 V max at IF = 50 A for unidirectional devices, and a peak forward surge current IFSM of 100 A (8.3 ms half sine-wave, unidirectional only). |
