RS2AB

Shandong Jingdao Microelectronics · Diodes - Fast Recovery Rectifiers · SMB

RS2AB from Shandong Jingdao Microelectronics, in a SMB. 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 diode; the device blocks up to 50 V (RS2AB) through 1000 V (RS2MB) reverse voltage and conducts 2 A average forward current.
2 Anode passive Anode terminal of the rectifier diode; maximum forward voltage is 1.3 V at 2 A and peak forward surge current is 60 A (8.3 ms half sine).
