onsemi · Fast Recovery / High Efficiency Diodes · DO-41

1N4934G from onsemi, 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 is the polarity-band lead (Style 1, pin 1) and the device is rated for 100 V VRRM and 1.0 A average forward current for the 1N4934 type.
2 ANODE passive Anode is the non-banded axial lead (Style 1, pin 2), and the leads are solderable with a lead temperature of 260 °C max for 10 seconds.
