PTZ16B-MS

MSKSEMI · Zener Diodes · SMA(DO-214AC)

PTZ16B-MS from MSKSEMI, in a SMA(DO-214AC). 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, identified by the color band on the SMA molded body; the Zener voltage VZ is 16.2 V min, 16.86 V typ and 18.3 V max at 20 mA for the PTZ16B-MS.
2 A passive Anode, the end opposite the color band; maximum power dissipation is 1.0 W at 25 °C ambient.

CAD (KiCad official)

  • Symbol: PTZ16B-MS
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: ptz16b-ms-etched.step / ptz16b-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ptz16b-ms.step / ptz16b-ms.glb are the bare package body.
