ACDBC340-HF

Overview

The ACDBC340-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a 40 V repetitive peak reverse voltage and a 3 A average forward rectified current capability. The device utilizes a DO-214AB (SMC) surface-mount package. Key electrical characteristics include a maximum forward voltage drop of 500 mV at 3 A and a low reverse leakage current of 500 µA at 40 V. It operates within a junction temperature range of -50°C to +150°C and meets RoHS compliance standards.

Feature Summary

• Ultra-fast switching performance with low forward voltage drop for high efficiency
• Guarding against overvoltage transients via robust surge current capability
• Low profile surface mount design optimized for board space constraints

Applications

• High-frequency DC-DC converter circuits
• Power supply freewheeling diodes
• Reverse polarity protection in automotive electronics

Procurement Notes

Verify the specific suffix 'HF' indicates Halogen-free compliance when sourcing. Confirm the package type matches DO-214AB (SMC) requirements for your PCB footprint. Ensure the voltage and current ratings align with your circuit's peak load conditions before finalizing procurement.

Selection Notes

Select this component for applications requiring fast recovery times and low conduction losses. The 40 V rating suits low-voltage power systems, while the 3 A current capacity supports moderate power loads. Consider thermal management due to the SMC package's dissipation characteristics in enclosed designs.
