ES1AL Equivalent & Substitute Parts Reference

Part Overview

The ES1AL (Manufacturer Part Number: ES1AL, Taiwan Semiconductor Corporation) is a surface mount super fast recovery rectifier diode designed for 1A average rectified current and a maximum DC reverse voltage of 50V. Its fast reverse recovery time and standard technology make it suitable for high-speed rectification tasks. The product is currently listed as "Not For New Designs," indicating the need to identify substitute components for ongoing or future design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ES1AL are determined based on electrical, mechanical, and compliance parameters explicitly provided. Only parts matching or exceeding the critical values for voltage rating, average rectified current, forward voltage, recovery speed, reverse recovery time, reverse leakage, capacitance, mounting type, package, operating temperature, and compliance certifications are included. Mechanical compatibility and electrical performance parameters form the basis of substitution grouping.

The following key parameters are strictly used for substitution:

• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io)
• Voltage - Forward (Vf) (Max) @ If
• Speed (Fast Recovery)
• Reverse Recovery Time (trr)
• Current - Reverse Leakage @ Vr
• Capacitance @ Vr, F
• Mounting Type
• Package / Case
• Operating Temperature - Junction
• RoHS/REACH/ECCN/HTSUS

Parameter Comparison

Engineering Selection Recommendations

ES1AL is categorized as "Not For New Designs," which requires engineering teams to select alternative parts for new projects or ongoing production. Substitute parts, such as ES1DLW, are "Active" and maintain compliance with ROHS3 and REACH requirements. Both ES1AL and ES1DLW share unrestricted ECCN and HTSUS classifications, supporting straightforward sourcing and regulatory compliance. Selection should be based on component status and explicit conformity to environmental and trade regulations as listed in supplied details.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for substitution of ES1AL in Diodes, Rectifiers category?
A: Substitution is determined by Voltage - DC Reverse (Vr), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) @ If, speed (Fast Recovery), Reverse Recovery Time (trr), Current - Reverse Leakage @ Vr, and Capacitance @ Vr, F.

Q: Does the package type impact compatibility between ES1AL and ES1DLW?
A: Yes, ES1AL uses SOD-123 while ES1DLW uses SOD-123W. Differences in package footprint must be considered for mechanical compatibility in PCB layouts.

Q: Are substitute parts compliant with environmental regulations?
A: Both ES1AL and ES1DLW are ROHS3 Compliant and REACH Unaffected, as per the provided parameters.

Q: Does the operating temperature range differ between ES1AL and ES1DLW?
A: ES1AL is rated for -55°C ~ 150°C. ES1DLW is rated for -55°C ~ 175°C, allowing a wider temperature range for ES1DLW.

Q: Can the ES1DLW be directly substituted for ES1AL in all applications?
A: Substitution is only supported when all key electrical and mechanical parameters, including package type, are compatible with the application requirements as provided in the specifications.
