Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB20100CT is determined by the following critical parameters: diode configuration (1 pair common cathode), technology (Schottky), maximum reverse voltage (100 V), and fast recovery speed (≤ 500ns, > 200mA). Substitute parts must maintain these core electrical characteristics to ensure functional compatibility.

The identified substitute parts are grouped into two categories:

Category 1: Surface Mount D2PAK Substitutes Parts maintaining identical mounting technology and package format (TO-263-3, D2PAK). These substitutes may vary in current rating and forward voltage characteristics while preserving the 100 V reverse voltage rating and Schottky technology.

Category 2: Through Hole TO-220 Substitutes Parts with equivalent electrical performance but different mounting technology (through hole) and package format (TO-220-3). These substitutes are applicable in designs where board layout and assembly methods accommodate through-hole mounting.

Substitution eligibility is based on matching the following parameters: diode configuration, technology type, maximum reverse voltage, fast recovery speed classification, and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Engineering Selection Recommendations

MBRB20100CT (Diodes Incorporated) Primary selection for surface mount D2PAK applications requiring 10A per diode at 100 V reverse voltage. Active product status with high inventory availability (45,300 pcs). AEC-Q101 automotive qualification and ROHS3 compliance support automotive and industrial applications. Forward voltage of 840 mV @ 10 A establishes baseline thermal performance expectations.

STPS10H100CG-TR (STMicroelectronics) Surface mount D2PAK substitute for applications with reduced current requirements (5A per diode). Maintains 100 V reverse voltage and fast recovery characteristics. Lower forward voltage (730 mV @ 5 A) and significantly reduced reverse leakage (3.5 µA @ 100 V) provide improved efficiency in low-current circuits. Suitable for sourcing flexibility and alternative supply chain management. Inventory availability is lower (4,960 pcs) compared to primary part.

STPS20H100CT (STMicroelectronics) Through-hole TO-220-3 substitute for applications where surface mount technology is not feasible. Maintains 10A per diode rating and 100 V reverse voltage. Forward voltage of 770 mV @ 10 A is lower than MBRB20100CT, indicating improved thermal efficiency. Highest inventory availability (195,950 pcs) supports high-volume through-hole assembly requirements. Suitable for legacy designs and applications requiring through-hole mounting technology.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory consistency with the primary part.

Frequently Asked Questions (FAQ)

Q: Can STPS10H100CG-TR replace MBRB20100CT in all applications?

A: STPS10H100CG-TR is a functional substitute only for applications where the current requirement does not exceed 5A per diode. The MBRB20100CT is rated for 10A per diode. Both parts share identical reverse voltage (100 V), diode configuration (1 pair common cathode), Schottky technology, and fast recovery speed characteristics. Package compatibility is identical (TO-263-3, D2PAK). Applications requiring the full 10A rating must use MBRB20100CT or STPS20H100CT.

Q: What are the mounting technology differences between these substitutes?

A: MBRB20100CT and STPS10H100CG-TR are both surface mount devices in TO-263-3 D2PAK packages, suitable for automated pick-and-place assembly on printed circuit boards. STPS20H100CT is a through-hole device in TO-220-3 package, requiring manual insertion or specialized through-hole assembly equipment. Board layout, assembly process, and thermal management requirements differ significantly between surface mount and through-hole technologies.

Q: Are all three parts automotive qualified?

A: MBRB20100CT carries AEC-Q101 automotive qualification. STPS10H100CG-TR and STPS20H100CT do not list automotive qualification in the provided specifications. For applications requiring automotive-grade components, MBRB20100CT is the specified selection. STPS10H100CG-TR and STPS20H100CT are suitable for industrial and commercial applications.

Q: How do forward voltage characteristics compare?

A: MBRB20100CT exhibits 840 mV forward voltage @ 10 A. STPS10H100CG-TR shows 730 mV @ 5 A, and STPS20H100CT shows 770 mV @ 10 A. Forward voltage differences reflect manufacturing process variations and current rating differences. Lower forward voltage reduces power dissipation and heat generation. Direct comparison at identical current levels is not available from provided specifications.

Q: What is the significance of reverse leakage current differences?

A: MBRB20100CT specifies 100 µA reverse leakage @ 100 V. STPS10H100CG-TR specifies 3.5 µA @ 100 V, and STPS20H100CT specifies 4.5 µA @ 100 V. Lower reverse leakage reduces standby power consumption and improves circuit efficiency. The MBRB20100CT exhibits higher reverse leakage, which may be significant in low-power or battery-operated applications.

Q: Are these parts interchangeable in PCB footprints?

A: MBRB20100CT and STPS10H100CG-TR share identical PCB footprints (TO-263-3, D2PAK). Direct footprint substitution is possible without board redesign. STPS20H100CT requires different PCB footprint (TO-220-3) and cannot be directly substituted without board layout modification.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Moisture sensitivity level is 1 (unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.
