ES3F-E3/9AT Equivalent & Substitute Parts Reference

Part Overview

The Vishay ES3F-E3/9AT is a general purpose fast recovery rectifier diode rated at 300V reverse voltage and 3A average rectified current, supplied in a DO-214AB (SMC) surface mount package. The device is actively available, compliant with ROHS3 and REACH regulations, and is suitable for applications requiring fast switching recovery with low forward voltage drop. Finding equivalent and substitute diodes is necessary for ongoing production flexibility, multi-sourcing strategies, and supply chain risk mitigation within the diodes, rectifiers category, especially when inventory constraints or sourcing requirements arise.

Substitute Part Grouping Explanation

Substitute and equivalent diodes are identified strictly based on matching the following core electrical and mechanical parameters: diode category, reverse voltage (Vr), average rectified current (Io), forward voltage (Vf) at specified current, recovery speed, reverse recovery time (trr), reverse leakage current at VR, mounting type, package specification, RoHS and REACH compliance, and product status. Only devices fulfilling all these criteria are included as equivalent and substitute options.

Each offers unlimited moisture sensitivity level rating (MSL 1). Selection is based only on confirmed product status and provided compliance, ensuring suitability for regulated and certified environments.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters are critical for substituting ES3F-E3/9AT in a circuit?
A1: Critical parameters are voltage - DC reverse (Vr), current - average rectified (Io), voltage - forward (Vf) at stated current, reverse recovery time (trr), and reverse leakage at Vr.

Q2: Are all substitute parts compatible with DO-214AB, SMC pad layouts?
A2: All listed substitute parts specify DO-214AB (SMC) package and are compatible with surface mount layouts conforming to this package standard.

Q3: How does RoHS3 and REACH compliance affect diode selection?
A3: Both ES3F-E3/9AT and its substitutes are ROHS3 compliant and REACH unaffected, supporting selection in applications requiring environmental and health safety regulations.

Q4: Is moisture sensitivity a consideration for these rectifier diodes?
A4: All compared parts specify Moisture Sensitivity Level (MSL) 1 (Unlimited), which indicates high tolerance to reflow and storage conditions.

Q5: Do substitute diodes differ in reverse recovery or leakage specifications?
A5: Reverse recovery time (trr) and leakage at Vr are comparable among the parts, with slight variation where noted in provided data.

Q6: Can substitutes be directly replaced in existing boards using ES3F-E3/9AT?
A6: All substitutes listed use the same DO-214AB (SMC) package and surface mount method, ensuring direct interchangeability within these constraints.

Q7: Do any inventory or production status details affect substitute selection?
A7: All referenced parts are currently active and listed as new original in stock, which helps ensure continuity in manufacturing and supply chain.
