SMCJ220A
MDD（Microdiode Electronics） · TVS · DO-214AB(SMC)
SMCJ220A from MDD（Microdiode Electronics）, 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, marked by the cathode band on the unidirectional SMCJ220A; connect to the positive side of the protected line (VRWM 220 V, VBR 246-272 V at 1 mA, VC max 356 V at IPP 4.2 A). |
| 2 | A | passive | Anode, the terminal opposite the cathode band on the unidirectional SMCJ220A; connect to the return/ground side (1500 W peak pulse power at 10/1000 µs). |
