TDZ30J

Nexperia · Zener Diodes · SOD-323F

TDZ30J from Nexperia, in a SOD-323F. 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 marking bar on the package; Zener working voltage for TDZ30J is 29.4 V to 30.6 V at IZ = 2 mA.
2 A passive Anode; forward voltage is at most 1.1 V at IF = 100 mA and forward current is limited to 250 mA.

CAD (KiCad official)

  • Symbol: TDZ30J
  • Footprint: Diode_SMD:D_SOD-323F
  • 3D model: SOD-323F (KiCad packages3D, STEP)
  • 3D model files: tdz30j-etched.step / tdz30j-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tdz30j.step / tdz30j.glb are the bare package body.
