ATV04A240JB-HF

Comchip · TVS · SMA(DO-214AC)

ATV04A240JB-HF from Comchip, in a SMA(DO-214AC). 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 (ATV04A240JB, VRWM 24.0V, VBR 26.7-29.5V at 1mA, VC 38.9V at IPP 10.28A); no polarity, interchangeable with the other terminal.
2 A2 passive Bidirectional TVS terminal (ATV04A240JB, VRWM 24.0V, VBR 26.7-29.5V at 1mA, VC 38.9V at IPP 10.28A); no cathode band on bipolar parts, so it is interchangeable with the other terminal.
