SMCJ48CAQ from Yangzhou Yangjie Elec Tech, 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 with no polarity marking; SMCJ48CAQ has 48 V working peak reverse voltage, 53.3 V to 58.9 V breakdown at 1 mA, and 77.4 V maximum clamping at 19.4 A. |
| 2 | A2 | passive | Second bi-directional TVS terminal with no polarity marking, interchangeable with the other terminal; rated for 1500 W peak pulse power with a 10/1000 µs waveform. |
