RS1MA

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

RS1MA from FUXINSEMI, 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 Pin 1 is the cathode, marked by the color band at the cathode end; the RS1MA is rated for a repetitive peak reverse voltage (VRRM) of 1000 V.
2 ANODE passive Pin 2 is the anode of the 1.0 A surface-mount fast recovery rectifier, with a maximum forward voltage of 1.30 V at IF = 1.0 A.
