Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBRB750-E3/45 are selected based on the following electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

• Technology: Schottky rectifier diode
• Current Rating: 7.5 A average rectified current
• Package: TO-263AB (D2PAK) surface mount configuration
• Mounting Type: Surface mount
• Speed Classification: Fast recovery ≤ 500ns, > 200mA (Io)
• Compliance: ROHS3 compliant

Voltage Rating Consideration: Substitute parts must have a DC reverse voltage rating equal to or greater than 50 V to maintain or exceed the electrical performance envelope of the original component. Parts with higher voltage ratings (60 V) provide enhanced voltage margin and are electrically compatible for applications designed for 50 V operation.

Forward Voltage Compatibility: Forward voltage characteristics must be evaluated within the context of the application's thermal and current management design. Variations in forward voltage at rated current are acceptable provided the substitute part operates within the same thermal and electrical operating envelope.

Engineering Selection Recommendations

MBRB760-E3/45 (Vishay General Semiconductor - Diodes Division)

The MBRB760-E3/45 is the manufacturer-recommended substitute for the MBRB750-E3/45. This part maintains identical electrical performance characteristics at rated current (7.5 A, 750 mV forward voltage) while providing an increased DC reverse voltage rating of 60 V compared to the original 50 V specification. The MBRB760-E3/45 is electrically and mechanically compatible with the MBRB750-E3/45 in all applications designed for 50 V operation. This part carries Last Time Buy status, indicating limited future availability. Both parts share identical package configuration (TO-263AB), operating temperature range (-65°C ~ 150°C), and ROHS3 compliance certification.

STPS745G-TR (STMicroelectronics)

The STPS745G-TR is an alternative substitute manufactured by STMicroelectronics. This part maintains the 7.5 A current rating and fast recovery speed classification. The STPS745G-TR has a DC reverse voltage rating of 45 V, which is 5 V lower than the original MBRB750-E3/45 specification. This part is suitable for applications where the circuit design operates at voltages below 45 V. The STPS745G-TR carries Active product status, ensuring long-term availability. The part features an extended maximum junction temperature rating of 175°C compared to 150°C for the MBRB750-E3/45. Packaging is supplied in Tape & Reel (TR) format. ROHS3 compliance is maintained.

Frequently Asked Questions (FAQ)

Q: Can the MBRB760-E3/45 be used as a direct replacement for the MBRB750-E3/45?

A: Yes. The MBRB760-E3/45 is electrically and mechanically compatible with the MBRB750-E3/45. Both parts share identical current ratings (7.5 A), forward voltage characteristics (750 mV @ 7.5 A), package configuration (TO-263AB), and operating temperature range (-65°C ~ 150°C). The MBRB760-E3/45 provides a higher DC reverse voltage rating (60 V versus 50 V), which is compatible with applications designed for 50 V operation.

Q: What is the voltage rating difference between the MBRB750-E3/45 and STPS745G-TR?

A: The MBRB750-E3/45 has a maximum DC reverse voltage rating of 50 V, while the STPS745G-TR is rated for 45 V. The STPS745G-TR is suitable for applications operating at voltages up to 45 V. For circuits requiring the full 50 V rating, the MBRB760-E3/45 is the appropriate substitute.

Q: Are all three parts housed in the same package?

A: Yes. The MBRB750-E3/45, MBRB760-E3/45, and STPS745G-TR all use the TO-263AB (D2PAK) surface mount package configuration with 2 leads plus tab. This ensures mechanical compatibility and identical PCB footprint requirements.

Q: What is the difference in forward voltage between the MBRB750-E3/45 and STPS745G-TR?

A: The MBRB750-E3/45 has a maximum forward voltage of 750 mV at 7.5 A. The STPS745G-TR forward voltage specification is provided at 15 A (840 mV @ 15 A), which is a different measurement condition. Direct comparison at identical current levels is not available from the provided specifications.

Q: Which substitute part has the longest product availability?

A: The STPS745G-TR carries Active product status, indicating ongoing production and long-term availability. The MBRB760-E3/45 carries Last Time Buy status, indicating limited future availability. The original MBRB750-E3/45 is classified as Obsolete.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The MBRB750-E3/45, MBRB760-E3/45, and STPS745G-TR are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the reverse leakage current difference between the parts?

A: The MBRB750-E3/45 has a reverse leakage current of 500 µA @ 50 V. The MBRB760-E3/45 has a reverse leakage current of 500 µA @ 60 V. The STPS745G-TR has a reverse leakage current of 100 µA @ 45 V, which is lower than both Vishay parts.
