S2DA Equivalent & Substitute Rectifier Diodes Reference

Part Overview

The S2DA, manufactured by Diodes Incorporated, is a general-purpose rectifier diode specified for 200 V reverse voltage and 1.5 A average rectified current, housed in a surface-mount DO-214AC (SMA) package. This device is listed as obsolete, necessitating the identification and use of compatible alternative models for ongoing production or maintenance. Substitutes are required to match the key electrical and mechanical attributes to ensure seamless design replacement without compromising device reliability or compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitute rectifier diodes are identified based on the following strictly controlled parameters: voltage rating, current rating, forward voltage, recovery speed, leakage at specified voltage, capacitance, package type, mounting method, compliance status, and environmental certifications. Substitution within the rectifier diode category requires precise equivalence in the listed mechanical and electrical properties to maintain functional compatibility and comply with RoHS and REACH requirements. The substitute part selection does not permit alteration of product fit or approved compliance standards.

Parameter Comparison

Engineering Selection Recommendations

The S2DA rectifier diode has an obsolete product status. For ongoing applications requiring compliance with ROHS3 and REACH standards, or continued adherence to EAR99 and HTSUS regulations, alternate selections must satisfy these specifications. The S2MA_HF substitute diode is classified as active, and carries equivalent compliance certifications, ensuring suitability for direct substitution under regulatory and inventory requirements as specified in the parameters provided.

Frequently Asked Questions (FAQ)

Q: What parameters are critical when substituting S2DA rectifier diodes?
A: Voltage rating, current rating, forward voltage, recovery speed, reverse leakage, capacitance, package type, mounting method, temperature range, and environmental certifications are critical. Only substitutions meeting these constraints are considered suitable.

Q: Is the S2MA_HF a direct mechanical substitute for S2DA in DO-214AC (SMA) footprints?
A: Yes. The S2MA_HF uses the same DO-214AC (SMA) package and surface mount configuration as the S2DA.

Q: Does the S2MA_HF maintain regulatory and certification equivalence with the S2DA?
A: Yes. Both S2DA and S2MA_HF are classified as ROHS3 Compliant, REACH Unaffected, with ECCN EAR99, and HTSUS 8541.10.0080.

Q: Are there any differences in voltage or temperature ratings that should be noted?
A: The S2MA_HF offers a higher reverse voltage (1000 V vs. 200 V) and a slightly wider operating temperature range (-65°C ~ 150°C for S2MA_HF vs. -55°C ~ 150°C for S2DA), both within the limits set for substitution in this analysis.

Q: Are the electrical performance parameters such as recovery speed, forward voltage, and reverse leakage matched?
A: Yes. All listed parameters for Standard Recovery speed, forward voltage, reverse leakage, and capacitance are equivalent at the specified test conditions.
