SF2003CT

NH · Fast Recovery / High Efficiency Diodes · TO-220AB

SF2003CT from NH, in a TO-220AB. 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 Anode of the first diode (Pin1 in the marking diagram), part of a 300 V, 20 A total dual common-cathode super fast rectifier.
2 K passive Common cathode of both diodes (Pin2), also connected to the metal tab/case, with 300 V maximum repetitive peak reverse voltage.
3 A2 passive Anode of the second diode (Pin3 in the marking diagram), sharing the common cathode on pin 2.
