HCEST23NC5VB

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

HCEST23NC5VB from HXY MOSFET, 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 Protected line terminal 1, connected through a TVS diode to common pin 3, with 5.0 V reverse working voltage and ±8 kV contact / ±15 kV air IEC 61000-4-2 ESD protection.
2 2 passive Protected line terminal 2, connected through a TVS diode to common pin 3, with 5.0 V reverse working voltage and ±8 kV contact / ±15 kV air IEC 61000-4-2 ESD protection.
3 3 passive Common node joining the two TVS diodes of pins 1 and 2, so the part protects one bidirectional line (pin 1 to pin 2) or two unidirectional lines referenced to pin 3.

CAD (KiCad official)

  • Symbol: HCEST23NC5VB
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: hcest23nc5vb-etched.step / hcest23nc5vb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hcest23nc5vb.step / hcest23nc5vb.glb are the bare package body.

Provenance

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