KDZVTR5.1B

ROHM Semicon · Zener Diodes · SOD-123FL

KDZVTR5.1B from ROHM Semicon, in a SOD-123FL. 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, marked by the bar on the package; Zener voltage VZ is 5.100 to 5.700 V at Iz = 40 mA, with IR max 20 µA at VR = 1.0 V.
2 A passive Anode; power dissipation is limited to 1000 mW and junction temperature to 150 °C.

CAD (KiCad official)

  • Symbol: KDZVTR5.1B
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: kdzvtr5-1b-etched.step / kdzvtr5-1b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); kdzvtr5-1b.step / kdzvtr5-1b.glb are the bare package body.
