5.0SMDJ250A
Zhengxin(正芯) · IC · DO-214AB(SMC)
5.0SMDJ250A from Zhengxin(正芯), 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 | K | passive | Cathode of the unidirectional TVS, marked by the band on the package; 5.0SMDJ250A has VRWM 250 V, VBR 279-309 V at 1.0 mA, and Vc 405 V max at IPP 12.3 A. |
| 2 | A | passive | Anode of the unidirectional TVS, the unbanded end; peak pulse power is 5000 W with a 10/1000 μs waveform. |
