CDBER70

Overview

The CDBER70 is a Schottky Barrier Diode manufactured by Comchip Technology, designed for surface mount applications. It features a 70V repetitive reverse voltage and a 70mA forward current rating. The device utilizes silicon epitaxial planar chips within an extremely thin 0503/SOD-723F leadless package. Key electrical parameters include a maximum forward voltage of 1V, a reverse current of 0.1uA, and a power dissipation of 150mW. It operates at temperatures up to +125°C and supports configurations for low voltage, high frequency inverters.

Feature Summary

• Low forward voltage drop for improved efficiency
• Extremely thin and leadless package design for small surface mounting
• Majority carrier conduction utilizing silicon epitaxial planar technology

Applications

• Low voltage high frequency inverters
• Free wheeling diode circuits
• Polarity protection systems

Procurement Notes

Verify the specific suffix (e.g., -HF) against the manufacturer's current production status, as some variants may be obsolete. Confirm the exact package designation, as documentation references both 0603 and 0503/SOD-723F forms. Ensure compliance with RoHS standards if required for the target assembly process. Cross-reference datasheet revisions to confirm thermal and electrical ratings match the intended operational environment.

Selection Notes

Select this component for space-constrained designs requiring a leadless surface mount solution. The low forward voltage makes it suitable for efficient rectification in low voltage circuits. Consider the 70mA current limit when designing load paths. The SOD-723F form factor allows for high-density PCB layouts compared to traditional through-hole or larger SMD packages.
