CDBQR43 Description

Short technical summary and product information.

The CDBQR43 is a Schottky barrier diode manufactured by Comchip Technology, designed for low-voltage, high-speed switching applications. It is rated for a maximum DC reverse voltage of 30V and an average forward rectified current of 200mA. The forward voltage is 1V maximum at 200mA, with a typical forward voltage as low as 0.33V at 2mA. Reverse leakage current is limited to 10µA at 25V reverse bias. The device offers a fast reverse recovery time of 5ns, making it suitable for high-frequency rectification and signal switching.

 

This diode is housed in a compact 0402 (1005 Metric) surface-mount package with the supplier device package designation 0402/SOD-923F. It supports an operating junction temperature up to 125°C. The component is RoHS3 compliant, REACH unaffected, and halogen free, meeting modern environmental standards. Its small footprint and low profile make it ideal for space-constrained designs in portable and embedded electronics.
