1.5SMC39CA
Brightking Elec (TAIWAN) · TVS · SMC(DO-214AB)
1.5SMC39CA from Brightking Elec (TAIWAN), 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 (no cathode band on CA types), reverse stand-off 33.30 V, breakdown 37.10~41.00 V at 1 mA, max clamping 53.9 V at 28.2 A peak pulse current. |
| 2 | A2 | passive | Second bidirectional TVS terminal, interchangeable with the other terminal, rated for 1500 W peak pulse power at 10/1000μs and 1 μA max leakage at 33.30 V. |
