Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SR3010-TP are qualified based on the following electrical and mechanical parameters:

Primary Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 3 A
• Package / Case: DO-201AD, Axial
• Mounting Type: Through Hole
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Compatibility Factors:

• Forward voltage (Vf) within acceptable operating range
• Reverse leakage current characteristics
• Operating temperature range
• RoHS and regulatory compliance status

The identified substitute parts SB3100-T (Diodes Incorporated) and SB3H100-E3/73 (Vishay General Semiconductor - Diodes Division) meet all primary matching criteria and maintain functional equivalence in applications requiring 100 V, 3 A Schottky rectification in DO-201AD through-hole configuration.

Parameter Comparison

Engineering Selection Recommendations

SR3010-TP (Micro Commercial Co) Primary choice for applications requiring the specified 100 V, 3 A Schottky rectification. Active product status with full ROHS3 compliance and REACH unaffected designation. Operating temperature range -55 to 125°C supports standard industrial applications. Forward voltage of 850 mV @ 3 A establishes baseline performance characteristics.

SB3100-T (Diodes Incorporated) Functionally equivalent substitute with improved forward voltage performance (790 mV @ 3 A) and extended operating temperature range (-65 to 150°C). Active product status with ROHS3 compliance. Reverse leakage current of 500 µA @ 100 V is intermediate between primary and alternative options. Suitable for applications requiring enhanced thermal performance or lower forward voltage dissipation.

SB3H100-E3/73 (Vishay General Semiconductor - Diodes Division) Functionally equivalent substitute with superior reverse leakage characteristics (20 µA @ 100 V) and highest maximum junction temperature rating (175°C). Active product status with ROHS3 compliance. Forward voltage of 800 mV @ 3 A provides performance between primary and SB3100-T options. Recommended for applications requiring minimal leakage current or extended thermal headroom.

All three parts maintain identical voltage and current ratings, package configuration, and fast recovery speed specifications. Selection between substitutes depends on specific application requirements for forward voltage, leakage current, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can SB3100-T or SB3H100-E3/73 be used as direct replacements for SR3010-TP in existing circuit designs?

A: Yes. Both substitute parts are functionally equivalent based on matching voltage ratings (100 V), current ratings (3 A), package configuration (DO-201AD axial through-hole), and fast recovery Schottky technology. No circuit modifications are required for direct substitution.

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

A: Forward voltage (Vf) differences of 50-60 mV between parts affect power dissipation in the diode. SR3010-TP specifies 850 mV @ 3 A, SB3100-T specifies 790 mV @ 3 A, and SB3H100-E3/73 specifies 800 mV @ 3 A. Lower forward voltage reduces heat generation. Selection depends on thermal design requirements and acceptable power loss in the application.

Q: How do reverse leakage current specifications differ, and does this matter for my application?

A: Reverse leakage current at 100 V varies significantly: SR3010-TP at 1 mA, SB3100-T at 500 µA, and SB3H100-E3/73 at 20 µA. Lower leakage current reduces standby power consumption and improves circuit efficiency. Applications sensitive to leakage current or requiring minimal standby power should prioritize SB3H100-E3/73.

Q: Are all three parts available in the same packaging format?

A: Yes. All three parts use DO-201AD axial through-hole package configuration. Mechanical fit and PCB layout compatibility are identical. Packaging differences exist only in supplier format: SR3010-TP is supplied in Tape & Reel (TR), while SB3100-T and SB3H100-E3/73 are supplied in Cut Tape (CT). This does not affect component performance or interchangeability.

Q: What are the operating temperature range differences, and when do they matter?

A: SR3010-TP operates from -55 to 125°C, SB3100-T from -65 to 150°C, and SB3H100-E3/73 to a maximum of 175°C. Extended temperature ranges provide design margin for applications in extreme environments or with high thermal loads. Standard industrial applications typically operate within -55 to 125°C range, making all three parts suitable.

Q: Are all parts RoHS3 compliant and REACH unaffected?

A: Yes. All three parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is used for automated assembly processes with reel-based component feeders. Cut Tape (CT) packaging is used for manual assembly or lower-volume applications. Both formats contain identical components; packaging format selection depends on assembly process requirements, not component performance.
