US2DA

onsemi · Diodes - Fast Recovery Rectifiers · SMA(DO-214AC)

US2DA from onsemi, in a SMA(DO-214AC). 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 rectifier, identified by the color band on the SMA/DO-214AC body; the junction-to-lead thermal resistance of 31 °C/W is referenced to this pin.
2 Anode passive Anode terminal of the rectifier; US2DA is rated for 200 V repetitive peak reverse voltage and 1.5 A average forward rectified current.
