PESD5V0L5UY

UMW · ESD And Surge Protection (TVS/ESD) · SOT-363

PESD5V0L5UY from UMW, in a SOT-363. 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 signal line of the unidirectional ESD diode array, with its surge and ESD ratings measured from this pin to pin 2 (peak pulse power 25 W, peak pulse current IPP 2.5 A at 8/20 µs, ESD up to 20 kV).
2 GND power_in Common reference pin for all five protected lines; the datasheet measures every surge and ESD parameter from pins 1, 3, 4, 5 and 6 to this pin.
3 3 passive Protected signal line of the unidirectional ESD diode array, with its surge and ESD ratings measured from this pin to pin 2 (clamping voltage VCL 12 V, IEC 61000-4-5 IPP 2.5 A).
4 4 passive Protected signal line of the unidirectional ESD diode array, with its surge and ESD ratings measured from this pin to pin 2 (clamping voltage VCL 12 V, IEC 61000-4-5 IPP 2.5 A).
5 5 passive Protected signal line of the unidirectional ESD diode array, with its surge and ESD ratings measured from this pin to pin 2 (clamping voltage VCL 12 V, IEC 61000-4-5 IPP 2.5 A).
6 6 passive Protected signal line of the unidirectional ESD diode array, with its surge and ESD ratings measured from this pin to pin 2 (clamping voltage VCL 12 V, IEC 61000-4-5 IPP 2.5 A).

CAD (KiCad official)

  • Symbol: PESD5V0L5UY
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SOT-363 (KiCad packages3D, STEP)
  • 3D model files: pesd5v0l5uy-etched.step / pesd5v0l5uy-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd5v0l5uy.step / pesd5v0l5uy.glb are the bare package body.
