ROHM Semicon · Zener Diodes · SOD-323
UDZVTE-175.6B from ROHM Semicon, in a SOD-323. 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 of the Zener diode, marked by the band at the top of the package; goes positive in reverse for regulation (UDZV5.6B: VZ 5.490 to 5.730 V at IZ = 5 mA). |
| 2 | A | passive | Anode of the Zener diode; power dissipation is limited to 200 mW and junction temperature to 150 °C. |
