PTZ9.1B-MS

MSKSEMI · Zener Diodes · SMA

PTZ9.1B-MS from MSKSEMI, in a SMA. 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, the end marked by the color band; the zener voltage VZ is 9.1 V typical (9.747 V measured, 10.2 V max) at IZT = 40 mA.
2 A passive Anode; power dissipation is limited to 1.0 W at 25 °C with junction temperature up to 150 °C.

  • Symbol: PTZ9.1B-MS
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: ptz9-1b-ms-etched.step / ptz9-1b-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ptz9-1b-ms.step / ptz9-1b-ms.glb are the bare package body.
