ESD5Z12

YFW · ESD And Surge Protection (TVS/ESD) · SOD-523

ESD5Z12 from YFW, in a SOD-523. 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 Cathode passive Cathode of the ESD5Z12 TVS diode, marked as pin 1 in the simplified SOD-523 outline; the device has a working peak reverse voltage (VRWM) of 12.0 V max and a breakdown voltage (VBR) of 13.3 V min at IT = 1 mA.
2 Anode passive Anode of the ESD5Z12 TVS diode, marked as pin 2 in the simplified SOD-523 outline; the maximum reverse leakage current is 1.0 µA at VRWM = 5 V.

  • Symbol: ESD5Z12
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: esd5z12-etched.step / esd5z12-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd5z12.step / esd5z12.glb are the bare package body.
