Overview
The CDBQR00340-HF is a single Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive reverse voltage (Vrrm) of 40 V and an average forward rectified current (Io) of 30 mA. The device exhibits a maximum forward voltage drop (Vf) of 370 mV at the rated current. Designed for surface mount applications, it utilizes an extremely thin package to optimize board space. The component operates within a junction temperature range up to a maximum of 125°C.
Feature Summary
- Extremely thin package design optimized for small surface mounting
- Low stored charge characteristics due to majority carrier conduction
- Guarding capability for overvoltage protection
Applications
- Surface mounted power supply circuits
- Reverse polarity protection in low current systems
- Clamping diodes in signal processing paths
Procurement Notes
