AUSMCJ24CA-HF from Comchip, in a DO-214AB(SMC). 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 TVS terminal (no polarity band on CA types) with VRWM 24.0 V, VBR 26.70 to 29.50 V at 1 mA and VC 38.9 V max at IPP 38.6 A. |
| 2 | A2 | passive | Second bi-directional TVS terminal (interchangeable with the other, no polarity band) rated for 1500 W peak pulse power at 10/1000 µs. |
