SMBJ8.5CA-E3

Vishay Intertech · TVS · SMB(DO-214AA)

SMBJ8.5CA-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 A1 passive Bi-directional terminal with no polarity marking; electrical characteristics apply in both directions (VWM 8.5 V, VBR 9.44 V to 10.4 V at 1.0 mA, VC 14.4 V at 41.7 A for SMBJ8.5CA).
2 A2 passive Second bi-directional terminal, interchangeable with the other terminal since bi-directional types carry no cathode band; 600 W peak pulse power with a 10/1000 μs waveform.
