UDZVTE-175.6B

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.

CAD (KiCad official)

  • Symbol: UDZVTE-175.6B
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: udzvte-175-6b-etched.step / udzvte-175-6b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); udzvte-175-6b.step / udzvte-175-6b.glb are the bare package body.
