Overview
The ACDBT-54C-HF is an automotive-grade Schottky barrier rectifier manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage of 30V and an average forward rectified current of 200mA. The device utilizes a surface-mount SOT-23 (TO-236-3) package, ensuring low profile and optimized board space. It is designed for high-efficiency switching applications with ultra-fast recovery characteristics.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- Ultra-fast switching speed for high-frequency efficiency
- Low forward voltage drop to minimize power loss
- Guardring structure provides enhanced overvoltage protection
Applications
- Automotive DC-DC converter circuits
- High-speed synchronous rectification in vehicle electronics
- Protection diodes in automotive control modules
Procurement Notes
Verify the specific suffix 'HF' indicates halogen-free compliance and RoHS adherence as per manufacturer specifications. Confirm that the AEC-Q101 qualification status is required for your specific automotive application tier. Ensure the SOT-23 footprint matches your PCB design constraints before finalizing procurement orders.
Selection Notes
Select this component when automotive reliability and small form factor are critical. The 30V rating suits low-voltage automotive systems. Compare against standard signal diodes if higher current capacity is needed, or consider larger packages like SMA/SMC for improved thermal dissipation in high-power scenarios.
Part Context
This part belongs to Comchip's automotive-specific Schottky diode lineup. It complements other small-signal variants like the ACDBT-54A-HF but offers distinct packaging and current ratings tailored for compact electronic assemblies in modern vehicles.
Replacement Considerations
Direct substitutes must match the 30V reverse voltage, 200mA forward current, and SOT-23 package. Verify equivalent AEC-Q101 qualification and switching speed parameters from alternative manufacturers to ensure functional compatibility.
