# 1N5359BRLG

**onsemi** · Zener Diodes · DO-27

1N5359BRLG from onsemi, in a DO-27. 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, the lead at the polarity band end of the body; it goes positive relative to the anode in zener (reverse) operation, with VZ 22.8 V min, 24 V nom and 25.2 V max at IZT = 50 mA for the 1N5359B. |
| 2 | A | passive | Anode, the lead at the end of the body opposite the polarity band; forward voltage is 1.2 V max at IF = 1.0 A. |
