SRA20100 Equivalent & Substitute Parts

Part Overview

The SRA20100 is a Schottky rectifier diode rated for 100V DC reverse voltage and 20A average rectified current, housed in a TO-220AC through-hole package. Manufactured by Taiwan Semiconductor Corporation, this component is classified as Active product status and is RoHS3 compliant. Substitute parts may be required due to inventory constraints, supply chain disruptions, or specific application requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the SRA20100 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 100V
• Technology: Schottky
• Package / Case: TO-220-2
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 150°C minimum
• RoHS3 Compliance

Allowable Parameter Variance:

• Voltage - Forward (Vf) (Max) @ If: Substitute values must not exceed the main part specification
• Current - Reverse Leakage @ Vr: Substitute values may differ within acceptable design margins
• Current - Average Rectified (Io): Must support minimum 20A operation

The MBR20100 manufactured by SMC Diode Solutions meets all mandatory matching criteria and is classified as a direct equivalent substitute for the SRA20100.

Parameter Comparison

Engineering Selection Recommendations

Both the SRA20100 and MBR20100 are Active product status components with ROHS3 compliance certification. The MBR20100 demonstrates superior forward voltage characteristics (880 mV versus 920 mV at 20A), resulting in lower power dissipation during operation. The MBR20100 exhibits higher reverse leakage current (1 mA versus 100 µA at 100V), which may be relevant in low-leakage applications but remains within acceptable operational parameters for standard rectification circuits.

Selection between these parts should be based on application-specific requirements regarding forward voltage drop and reverse leakage characteristics, as well as inventory availability and supply chain considerations. Both components are electrically and mechanically interchangeable within the TO-220AC package footprint.

Frequently Asked Questions (FAQ)

Q: Can the MBR20100 be used as a direct replacement for the SRA20100?

A: Yes. Both components share identical voltage ratings (100V), package configuration (TO-220-2), mounting type (through hole), operating temperature range (-55°C to 150°C), and Schottky technology. Both are RoHS3 compliant and Active product status.

Q: What is the significance of the forward voltage difference between these parts?

A: The MBR20100 exhibits a lower forward voltage drop (880 mV) compared to the SRA20100 (920 mV) at 20A operation. This 40 mV difference results in reduced power dissipation and heat generation in the substitute part, which may provide thermal performance benefits in high-current applications.

Q: Does the higher reverse leakage current of the MBR20100 affect circuit performance?

A: The MBR20100 reverse leakage current is 1 mA at 100V, compared to 100 µA for the SRA20100. This tenfold increase is measurable but remains within acceptable parameters for standard rectification applications. Applications requiring extremely low leakage characteristics should evaluate this parameter against specific circuit requirements.

Q: Are both parts available in the same packaging format?

A: Yes. Both the SRA20100 and MBR20100 are housed in TO-220-2 packages suitable for through-hole mounting. The SRA20100 is supplied in standard packaging, while the MBR20100 is supplied in tube packaging. Both are compatible with identical PCB footprints and thermal management solutions.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS3 compliant and carry EAR99 ECCN classification. The SRA20100 is REACH Unaffected, while the MBR20100 is REACH Affected. Both maintain Moisture Sensitivity Level 1 (Unlimited).
