S3A-E3

Vishay Intertech · Diodes - General Purpose · DO-214AB

S3A-E3 from Vishay Intertech, in a 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 K passive Cathode, the end marked by the color band; the diode conducts from anode to cathode with VF of 1.15 V max at 2.5 A and blocks up to VRRM (50 V to 1000 V depending on S3A-S3M type).
2 A passive Anode terminal of the single rectifier diode, carrying up to 3.0 A average forward current (IF(AV) at TL = 103 °C).
