SMBJ26AHE3_B
Vishay Intertech · ESD And Surge Protection (TVS/ESD) · DO-214AA(SMB)
SMBJ26AHE3_B from Vishay Intertech, in a DO-214AA(SMB). 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 TVS, marked by the cathode band, connected to the protected line (positive side) with VWM 26 V and VBR 28.9 V to 31.9 V at 1 mA. |
| 2 | Anode | passive | Anode terminal of the unidirectional TVS, connected to ground or return, clamping at a maximum of 42.1 V at IPPM 14.3 A (10/1000 µs). |
