SMCJ150A
Taisko · Electrostatic And Surge Protection (TVS/ESD) · SMC(DO-214AB)
SMCJ150A from Taisko, 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 | Cathode | passive | Cathode terminal of the unidirectional TVS (SMCJ150A: VR 150 V, VBR 167-185 V at 1 mA, VC 243 V at IPP 6.2 A), marked by the band; connect to the protected positive line. |
| 2 | Anode | passive | Anode terminal of the unidirectional TVS (SMCJ150A), connected to ground or the return line; peak pulse power rating is 1500 W (10/1000us). |
