PANJIT International · Schottky Barrier Diodes (SBD) · DO-41

1N5819_AY_100A1 from PANJIT International, 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 Cathode passive Cathode axial lead, identified by the color band on the DO-41 body; for the 1N5819 the maximum DC blocking voltage is 40 V, with 1 A average forward current at 0.375" (9.5 mm) lead length.
2 Anode passive Anode axial lead; the 1N5819 is rated 40 V maximum recurrent peak reverse voltage and 25 A peak forward surge current (8.3 ms half sine-wave).
