AES2DF-HF Equivalent & Substitute Parts Reference

Part Overview

The Comchip Technology AES2DF-HF is a 200 V, 2 A fast recovery surface-mount rectifier diode in the SMAF package. It is intended for general-purpose rectification where fast recovery time is required. This diode is AEC-Q101 qualified for automotive use and complies with RoHS3 standards, with product status listed as active. Alternative models may be required for reasons such as sourcing constraints, inventory management, or specific packaging preferences, while maintaining specified electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution is determined strictly by matching key electrical and mechanical parameters: DC reverse voltage, average rectified current, forward voltage, reverse recovery time, reverse leakage current, speed classification, operating temperature range, mounting type, package, automotive qualification, RoHS compliance, and moisture sensitivity level. Only models presenting identical or within-specification values for all these fields are considered parametric equivalents.

Key parameters for substitution:

Voltage - DC Reverse (Vr) (Max)
Current - Average Rectified (Io)
Voltage - Forward (Vf) (Max) @ If
Reverse Recovery Time (trr)
Current - Reverse Leakage @ Vr
Speed
Package / Mounting Type
Operating Temperature - Junction
Grade / Qualification
RoHS Status
Moisture Sensitivity Level (MSL)

Engineering Selection Recommendations

Select substitute parts with matching or better product status (active), identical or compliant RoHS standards, automotive qualification (AEC-Q101) if required, and identical or compatible moisture sensitivity levels. ES2DAH is AEC-Q101 qualified for automotive use, equivalent to AES2DF-HF in grade and qualification. Consider package and mounting type strictly as specified.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters when selecting a substitute for AES2DF-HF?
A1: Voltage - DC Reverse (Vr), Current - Average Rectified (Io), Voltage - Forward (Vf), Reverse Recovery Time (trr), Reverse Leakage Current, Speed, Package / Case, Mounting Type, Operating Temperature Range, Grade / Qualification, RoHS Status, and Moisture Sensitivity Level.

Q2: Are all listed substitutes suitable for automotive applications?
A2: Only models explicitly marked with automotive grade and AEC-Q101 qualification, such as ES2DAH, match the automotive rating of AES2DF-HF.

Q3: Can alternatives with different package codes be used?
