HER102

HL(Haolin Elec) · Diodes - General Purpose · DO-41

HER102 from HL(Haolin Elec), in a DO-41. 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, marked by the cathode band on the DO-41 body; HER102 is rated for 100V VRRM, 70V VRMS and 100V DC blocking voltage.
2 A passive Anode terminal of the DO-41 axial diode; HER102 is rated for 1.0A average forward rectified current at TA=55 C and 30A peak surge current.
