SMBJ24CAHE3_B

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

SMBJ24CAHE3_B 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 First terminal of the bidirectional (CA suffix) TVS; electrical characteristics apply in both directions, with no polarity marking, VWM 24 V, VBR 26.7 V to 29.5 V at 1 mA, and VC max 38.9 V at IPPM 15.4 A.
2 A2 passive Second terminal of the bidirectional TVS, interchangeable with the first terminal, with 600 W peak pulse power capability on a 10/1000 μs waveform.
