1N4761A

Tak Cheong · Zener Diodes · DO-41

1N4761A from Tak Cheong, 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 The cathode is marked by the polarity band on the hermetically sealed glass body, and the device is rated for 1 W maximum steady-state dissipation at TL≤50℃ with 3/8" lead length, derating 6.67 mW/℃ above 50℃.
2 Anode passive The anode is the terminal opposite the polarity band, and the datasheet gives no anode-specific limits beyond the device operating and storage range of -65 to +200 °C.
