Overview
The AES2DF-HF is an automotive-grade Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in an SMAF-2 surface-mount package. Key electrical specifications include a maximum repetitive peak reverse voltage (VRRM) of 200 V and an average forward rectified current (IF) of 2 A. The device exhibits a maximum forward voltage drop (VF) of 950 mV at rated current and a low reverse leakage current (IR) of 5 µA. It supports a non-repetitive peak forward surge current (IFSM) of 50 A. The component is qualified to AEC-Q101 standards and operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Automotive qualification compliant with AEC-Q101 standards for reliability in vehicle electronics.
- Schottky technology enables fast switching speeds and reduced power loss during conduction.
- High thermal stability allows operation up to a maximum junction temperature of 150 °C.
Applications
- Automotive DC-DC converter circuits
- Vehicle power distribution modules
- Battery management system rectification
Procurement Notes
Verify the specific datasheet version and AEC-Q101 certification status directly with Comchip Technology or authorized distributors before integration. Confirm that the SMAF-2 footprint matches the target PCB design. Ensure supply chain sources are authorized to guarantee component authenticity and traceability for automotive safety requirements.
Selection Notes
Select this component when a 200 V reverse voltage rating and 2 A continuous current capacity are required in a compact SMAF-2 package. It is suitable for applications demanding high efficiency and fast recovery characteristics. Consider the 950 mV forward voltage drop for thermal management calculations. Verify compatibility with automated assembly processes due to the surface-mount form factor.
Part Context
This part belongs to Comchip Technology's automotive diode portfolio, specifically designed for robust performance in harsh environments. The AES series utilizes silicon Schottky technology to provide reliable rectification. The 'HF' suffix typically indicates halogen-free compliance, aligning with environmental regulations for electronic components used in modern manufacturing.
Replacement Considerations
Cross-reference with other AEC-Q101 qualified Schottky diodes offering 200 V and 2 A ratings in SMAF-2 packages. Verify pinout compatibility and thermal resistance parameters before substitution. Ensure any alternative meets the same automotive reliability standards and operating temperature range.
