Overview
The ACGRA4004-HF is a standard recovery rectifier diode manufactured by Comchip Technology. It features a maximum DC reverse voltage of 400 V and an average forward current rating of 1 A in the DO-214AC (SMA) surface-mount package. The device exhibits a low reverse leakage current of 5 µA at 400 V and a junction capacitance of 2.5 pF at 4 V, 1 MHz. Qualified to AEC-Q101 standards for automotive applications, it operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q101 standards
- Surface-mount construction in compact DO-214AC (SMA) package
- High thermal stability supporting operation up to 150°C junction temperature
Applications
- Automotive electronic circuits requiring robust rectification
- General-purpose power supply input stages
- Protection against voltage transients induced by inductive load switching
Procurement Notes
Verify the specific part number suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure compliance with RoHS3 directives and check for any recent product change notifications that may affect material composition or manufacturing location before finalizing procurement specifications.
Selection Notes
Select this component when a surface-mount solution is required for 400 V blocking applications. The SMA footprint offers space efficiency compared to through-hole alternatives. Confirm that the standard recovery speed meets the circuit's frequency requirements and that the 1 A current rating aligns with the system's peak load demands.
Part Context
This component belongs to the ACGRA series of glass-passivated general-purpose rectifiers from Comchip Technology. The series provides various voltage ratings within the same SMA package family, allowing designers to maintain consistent board layouts while adjusting voltage capabilities. The 'HF' designation indicates halogen-free compliance.
Replacement Considerations
Cross-reference with other SMA-packaged 400 V, 1 A standard recovery diodes such as the MBR0540L or SS14 if higher speed is needed, though electrical characteristics will differ. Verify pinout compatibility and thermal dissipation requirements when substituting.
