MCC(Micro Commercial Components) · TVS · SOD-123FL
SMF40A-TP from MCC(Micro Commercial Components), in a SOD-123FL. 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 of the unidirectional TVS (marked with the cathode mark band); connects to the protected line, with VWM 40V, breakdown 44.4V min to 49.1V max at 1mA, and max clamping voltage 64.5V at 3.1A IPP. |
| 2 | Anode | passive | Anode of the unidirectional TVS; connects to ground/return side of the protected line, rated for 200W peak pulse power (10/1000μs). |
