CPDT6-5V0UPC-HF

Leiditech · ESD And Surge Protection (TVS/ESD) · SOT-26

CPDT6-5V0UPC-HF from Leiditech, in a SOT-26. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 I/O1 passive Protected data I/O line 1. Connects to steering diodes clamping to REF1 (GND, pin 2) and REF2 (VCC, pin 5). Typical junction capacitance ~1.5pF line-to-line.
2 REF1/GND power_in Negative reference (REF1). Connect directly to the board ground plane via the shortest path to minimize parasitic inductance during ESD/EFT/surge events.
3 I/O3 passive Protected data I/O line 3. Connects to steering diodes clamping to REF1 (GND, pin 2) and REF2 (VCC, pin 5). Clamping voltage 25V max at Ipp=12A (8/20µs).
4 I/O4 passive Protected data I/O line 4. Connects to steering diodes clamping to REF1 (GND, pin 2) and REF2 (VCC, pin 5).
5 REF2/VCC power_in Positive reference (REF2). Typically connected to the protected supply rail (e.g., VBUS/VCC ~5V); steering diodes clamp high-going transients to this rail. VRWM=5V.
6 I/O2 passive Protected data I/O line 2. Connects to steering diodes clamping to REF1 (GND, pin 2) and REF2 (VCC, pin 5).
