SMCJ40CA-TR from STMicroelectronics, 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 | A1 | passive | Bidirectional TVS terminal with no polarity; either terminal may connect to the protected line, with stand-off voltage VRM 40 V and breakdown 44.4 to 46.7 V in both directions. |
| 2 | A2 | passive | Second bidirectional TVS terminal with no polarity; 1500 W (10/1000 µs) peak pulse power, clamping 64.5 V at 24 A (10/1000 µs). |
