Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB10100CT is determined by the following critical parameters:

Primary Substitution Criteria:

• Diode configuration: 1 Pair Common Cathode
• Technology: Schottky
• Maximum reverse voltage: 100 V
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting type: Surface Mount
• Fast recovery speed: ≤ 500ns, > 200mA (Io)

Secondary Compatibility Parameters:

• Current rating (per diode): 5A minimum
• Forward voltage (Vf): ≤ 850 mV @ 5A
• Reverse leakage current: ≤ 100 µA @ 100 V
• Operating temperature range: -55°C to 175°C minimum
• RoHS3 compliance

Parts are grouped into two categories:

Direct Equivalents (5A Rating): Parts with identical 5A current rating, matching all primary criteria, and compatible secondary parameters.

Higher Current Alternatives (10A Rating): Parts with elevated current ratings that maintain all primary electrical and package specifications, suitable for applications where current headroom is beneficial.

Parameter Comparison

Engineering Selection Recommendations

MBRB10100CT (SMC Diode Solutions): This part maintains identical electrical specifications and package configuration to the primary MBRB10100CT from Diodes Incorporated. Both are ROHS3 compliant and active in production. The SMC variant exhibits higher reverse leakage current (1 mA versus 100 µA) and a reduced maximum junction temperature of 150°C compared to 175°C. Selection of the SMC variant is appropriate for applications where the primary source experiences supply limitations and the higher leakage and lower temperature rating are acceptable within circuit design margins.

MBRB20100CT (Diodes Incorporated): This part is a direct manufacturer equivalent with doubled current rating (10A versus 5A per diode) while maintaining the same 100 V reverse voltage, package configuration, and thermal range (-55°C to 175°C). Both parts carry AEC-Q101 automotive qualification and ROHS3 compliance. The MBRB20100CT is suitable for applications requiring higher current capacity or where design margin improvement is beneficial. Significantly higher inventory availability (45300 units) supports supply chain continuity.

STPS10H100CG-TR (STMicroelectronics): This part matches the 5A current rating and 100 V reverse voltage specifications with identical package configuration. The STPS10H100CG-TR exhibits superior forward voltage characteristics (730 mV versus 840 mV @ 5A) and substantially lower reverse leakage current (3.5 µA versus 100 µA @ 100 V). Operating temperature specification is provided as maximum 175°C. This part is ROHS3 compliant and active in production with 4960 units in stock. Selection is appropriate for applications where lower forward voltage drop and leakage current provide circuit performance benefits.

All substitute parts maintain AEC-Q101 or equivalent automotive-grade qualification status where specified, ensuring suitability for automotive and industrial applications requiring high reliability standards.

Frequently Asked Questions (FAQ)

Q: Can MBRB10100CT be directly replaced with MBRB20100CT?

A: Yes. Both parts share identical reverse voltage (100 V), diode configuration (1 pair common cathode), package (TO-263-3 D2PAK), and thermal range (-55°C to 175°C). The MBRB20100CT provides doubled current capacity (10A versus 5A per diode). Direct substitution is electrically and mechanically compatible. Applications designed for 5A operation will function with the 10A rated part without modification.

Q: What is the difference between MBRB10100CT from Diodes Incorporated and SMC Diode Solutions?

A: Both parts share identical part number designation and package configuration. Key differences are: SMC variant exhibits 10× higher reverse leakage current (1 mA versus 100 µA @ 100 V) and reduced maximum junction temperature (150°C versus 175°C). Forward voltage specifications are comparable (850 mV versus 840 mV @ 5A). Selection depends on circuit leakage tolerance and thermal operating requirements.

Q: Is STPS10H100CG-TR a suitable replacement for MBRB10100CT?

A: Yes, for applications where forward voltage and leakage current performance are critical. The STPS10H100CG-TR maintains identical 5A current rating, 100 V reverse voltage, and TO-263-3 D2PAK package. The STMicroelectronics part provides superior forward voltage (730 mV versus 840 mV @ 5A) and significantly lower reverse leakage (3.5 µA versus 100 µA @ 100 V). Substitution is electrically and mechanically compatible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MBRB10100CT (both manufacturers), MBRB20100CT, and STPS10H100CG-TR are all ROHS3 compliant, meeting environmental and regulatory requirements for lead-free electronic components.

Q: What is the impact of higher current rating in MBRB20100CT?

A: The MBRB20100CT 10A rating provides increased current handling capacity compared to the 5A MBRB10100CT. Applications designed for 5A operation will function with the higher-rated part. The increased rating provides design margin and thermal headroom. No circuit modification is required for direct substitution.

Q: Do all substitute parts have automotive qualification?

A: MBRB10100CT (Diodes Incorporated) and MBRB20100CT carry explicit AEC-Q101 automotive qualification with automotive grade designation. MBRB10100CT (SMC Diode Solutions) and STPS10H100CG-TR do not specify automotive grade or AEC-Q101 qualification in provided data. Selection for automotive applications should prioritize parts with explicit AEC-Q101 certification where required by design specifications.

Q: What is the operating temperature range for each substitute?

A: MBRB10100CT (Diodes Inc.) and MBRB20100CT: -55°C to 175°C. MBRB10100CT (SMC Diode Solutions): -55°C to 150°C. STPS10H100CG-TR: Maximum 175°C (minimum not specified). Applications operating near upper temperature limits should verify compatibility with the selected part's thermal specification.

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

A: Yes. All substitute parts use TO-263-3 D2PAK (2 Leads + Tab) surface mount package configuration. Mechanical compatibility and PCB layout remain identical across all options. Packaging format does not restrict substitution selection.
