MMBZ9V1A

JSMSEMI · ESD And Surge Protection (TVS/ESD) · SOT-23

MMBZ9V1A from JSMSEMI, in a SOT-23. 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 1 passive Cathode 1 of dual transient voltage suppressor providing unidirectional ESD protection with Pin 3 (common anode), with breakdown voltage 8.65-9.56V and clamping voltage of 14V at 1.7A peak pulse current.
2 2 passive Cathode 2 of dual transient voltage suppressor providing unidirectional ESD protection with Pin 3 (common anode), with breakdown voltage 8.65-9.56V and clamping voltage of 14V at 1.7A peak pulse current.
3 3 power_in Common Anode connection shared by both transient voltage suppressor diodes, providing the return path for both unidirectional protection circuits (Pins 1-3 and Pins 2-3).

  • Symbol: MMBZ9V1A
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbz9v1a-etched.step / mmbz9v1a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbz9v1a.step / mmbz9v1a.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: JSMSEMI datasheet (5 pp, sha256 2ed1d6c11b4c2134, retrieved 2026-09-29, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
