BZT52C27S-WP

SY(顺烨) · Zener Diodes · SOD-323

BZT52C27S-WP from SY(顺烨), 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, marked by the cathode bar on the body; zener voltage VZ is 27 V nominal (25.1 V to 28.9 V) at IZT = 5 mA.
2 A passive Anode, the end opposite the cathode bar; maximum power dissipation is 300 mW per the features list.

CAD (KiCad official)

  • Symbol: BZT52C27S-WP
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: bzt52c27s-wp-etched.step / bzt52c27s-wp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52c27s-wp.step / bzt52c27s-wp.glb are the bare package body.
