CPDQ3V3U-HF Description

Short technical summary and product information.

The Comchip Technology CPDQ3V3U-HF is a uni-directional Zener-type TVS diode designed for ESD protection in general-purpose applications. It features a 3.3V reverse standoff voltage and a maximum clamping voltage of 10.4V at 9.8A peak pulse current (8/20µs waveform). The device provides robust ESD protection meeting IEC 61000-4-2 Level 4, with ±15kV air discharge and ±8kV contact discharge ratings.

 

Packaged in a compact SOD-923F surface-mount package (also referenced as 0402), this diode is halogen-free and RoHS compliant. It offers a low leakage current of 2.5µA at rated voltage and a typical junction capacitance of 80pF. The part is suitable for protecting sensitive electronics in space-constrained designs, with an operating temperature range of -55°C to 150°C.
