SR3100M

MOSPEC Semicon · Schottky Barrier Diodes (SBD) · DO-201AD

SR3100M from MOSPEC Semicon, in a DO-201AD. 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, indicated by the polarity band on the DO-201AD molded plastic case; blocks up to 100 V DC reverse voltage (VRRM/VR) for SR3100.
2 A passive Anode; carries up to 3 A average forward current (IO) with maximum VF of 0.85 V at IF = 3.0 A for SR3100.
