TPMMQA33VT1G

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-23-6

TPMMQA33VT1G from TECH PUBLIC, in a SOT-23-6. 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 IO1 passive Protected line 1 (uni-directional ESD clamp to the common node), 33V reverse working voltage max, 8/20µs 4A peak pulse current.
2 GND power_in Common ground node of the TVS array, tied internally to pin 5; junction capacitance is specified IO to GND at 33pF max.
3 IO2 passive Protected line 2 (uni-directional ESD clamp to the common node), ±30kV air/contact ESD per IEC 61000-4-2.
4 IO3 passive Protected line 3 (uni-directional ESD clamp to the common node), 55V max clamping at 1A (8/20µs).
5 GND power_in Common ground node of the TVS array, tied internally to pin 2.
6 IO4 passive Protected line 4 (uni-directional ESD clamp to the common node), 60V max clamping at 4A (8/20µs).

CAD (KiCad official)

  • Symbol: TPMMQA33VT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: tpmmqa33vt1g-etched.step / tpmmqa33vt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpmmqa33vt1g.step / tpmmqa33vt1g.glb are the bare package body.
