SMCJ30CA-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 | Terminal 1 | passive | Bidirectional Transil terminal with no polarity (SMCJ30CA): stand-off voltage VRM 30 V, breakdown 33.3 V min to 35.1 V max at 1 mA, clamping 48.4 V at 32 A (10/1000 µs). |
| 2 | Terminal 2 | passive | Second bidirectional Transil terminal, interchangeable with terminal 1 (no cathode band on CA types), with 1500 W peak pulse power (10/1000 µs) and IRM max 0.2 µA at 25 °C. |
