SMCJ40CAHE3-TP from MCC(Micro Commercial Components), in a SMC(DO-214AB). 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 | Terminal 1 | passive | First terminal of the bi-directional (C-suffix) TVS, with no polarity and no cathode mark; it is interchangeable with terminal 2 and the part has VWM 40V, VBR 44.4-49.1V at 1mA and max VC 64.5V at 23.3A IPP. |
| 2 | Terminal 2 | passive | Second terminal of the bi-directional (C-suffix) TVS, with no polarity and no cathode mark; it is interchangeable with terminal 1 and the part has 1500W (min) peak pulse power on a 10/1000μs waveform. |
