SMF24CA

hongjiacheng · ESD And Surge Protection (TVS/ESD) · SOD-123FL

SMF24CA from hongjiacheng, in a SOD-123FL. 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 Bidirectional TVS terminal (no cathode band on the SMF24CA); stand-off voltage VRWM 24 V, breakdown 26.7 to 29.5 V at 1 mA, max clamping 38.9 V at 5.1 A IPP, interchangeable with the other terminal.
2 A2 passive Bidirectional TVS terminal (no cathode band on the SMF24CA); stand-off voltage VRWM 24 V, breakdown 26.7 to 29.5 V at 1 mA, max clamping 38.9 V at 5.1 A IPP, interchangeable with the other terminal.
