Overview
The AES1E-HF is a super fast recovery rectifier manufactured by Comchip Technology, designed for automotive applications. It features a single diode configuration in an SMA (DO-214AC) surface-mount package. Key electrical parameters include a maximum repetitive reverse voltage of 300 V and a continuous forward current rating of 1 A. The device exhibits a low forward voltage drop of 1.25 V at rated current and a rapid reverse recovery time of 35 ns. It supports a maximum surge current of 50 A and operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Automotive-grade reliability compliant with AEC-Q101 standards
- Super fast recovery characteristics for high-frequency switching efficiency
- Low thermal resistance and robust surge current handling capability
Applications
- Automotive power supply circuits
- DC-DC converter output rectification
- High-speed switching power supplies
Procurement Notes
Verify the specific suffix and packaging format against the official datasheet before ordering. Confirm RoHS compliance status and ensure the supplier provides valid traceability documentation for automotive-grade components. Check for any recent production changes or obsolescence notices from Comchip Technology.
Selection Notes
Select this component when automotive qualification is required alongside super fast recovery performance. Ensure the circuit design accommodates the 300 V reverse voltage rating and 1 A forward current limits. Consider the DO-214AC package dimensions for PCB layout compatibility and thermal management requirements.
Part Context
This part belongs to Comchip Technology's AES series of automotive rectifiers. It shares the SMA package form factor with other variants but is distinguished by its 1 A current rating and 300 V blocking voltage. The series targets high-reliability automotive electronics requiring fast switching speeds.
Replacement Considerations
Cross-reference with other AEC-Q101 qualified SMA super fast recovery diodes having matching 1 A and 300 V ratings. Verify pinout compatibility and thermal characteristics before substitution.
