TPE3662BC3

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-323

TPE3662BC3 from TECH PUBLIC, in a SOT-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 IO1 passive Protected line 1 (CAN bus line) with a TVS diode to common pin 3; reverse working voltage 36V max, breakdown 38V min at 1mA.
2 IO2 passive Protected line 2 (CAN bus line) with a TVS diode to common pin 3; reverse working voltage 36V max, breakdown 38V min at 1mA.
3 GND power_in Common pin joining both TVS diodes, the ground reference for IO1 and IO2; the datasheet labels it only PIN 3 and refers to 'IO to GND' capacitance.

  • Symbol: TPE3662BC3
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: tpe3662bc3-etched.step / tpe3662bc3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpe3662bc3.step / tpe3662bc3.glb are the bare package body.
