Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB1535CTHE3_A/I is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 35 V
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount

Allowable Parameter Variations:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 7.5 A
• Voltage - Forward (Vf) (Max) @ If: Equal to or lower than 840 mV @ 15 A
• Operating Temperature - Junction: Equal to or greater than -65°C to 150°C range
• Current - Reverse Leakage @ Vr: Equal to or lower than 100 µA @ 35 V

The MBRS1035CT MNG meets all mandatory compatibility criteria and provides enhanced current rating, making it a valid substitute for the obsolete MBRB1535CTHE3_A/I.

Parameter Comparison

Engineering Selection Recommendations

The MBRS1035CT MNG is a direct substitute for the obsolete MBRB1535CTHE3_A/I based on the following factors:

Product Status: The MBRS1035CT MNG carries Active product status, ensuring continued availability and supply chain reliability compared to the Obsolete MBRB1535CTHE3_A/I.

Electrical Compatibility: Both components share identical voltage ratings (35 V DC reverse), identical diode configuration (1 Pair Common Cathode), and identical reverse leakage characteristics (100 µA @ 35 V). The MBRS1035CT MNG provides a higher current rating (10 A versus 7.5 A), which is compatible with applications designed for the original part.

Package and Mounting: Both parts utilize the TO-263-3 D2PAK surface mount package with identical pinout and mechanical dimensions, enabling direct board-level substitution without layout modifications.

Compliance: Both components are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, maintaining equivalent environmental and regulatory compliance profiles.

Temperature Range: The MBRS1035CT MNG operates across -55°C to 150°C, which encompasses the upper portion of the original part's -65°C to 150°C range. Applications operating above -55°C experience no thermal limitation.

Frequently Asked Questions (FAQ)

Q: Can the MBRS1035CT MNG be used as a direct replacement for the MBRB1535CTHE3_A/I without circuit modifications?

A: Yes. Both components share identical voltage ratings, diode configuration, package type, and pinout. The MBRS1035CT MNG provides higher current capacity (10 A versus 7.5 A), which is compatible with existing circuit designs. No circuit modifications are required.

Q: What is the significance of the higher current rating on the MBRS1035CT MNG?

A: The MBRS1035CT MNG is rated for 10 A average rectified current per diode, compared to 7.5 A on the original part. This higher rating provides additional design margin and thermal headroom in applications operating near the original part's current limits. Circuits designed for 7.5 A operation experience no adverse effects from the substitute's higher rating.

Q: Are the forward voltage characteristics compatible between these two parts?

A: The MBRS1035CT MNG exhibits a forward voltage of 800 mV @ 10 A, compared to 840 mV @ 15 A on the original part. The substitute's lower forward voltage reduces power dissipation in the diode, which is beneficial for thermal management. Both parts meet the fast recovery speed specification (≤ 500ns, > 200mA).

Q: Does the operating temperature range difference affect substitution?

A: The MBRS1035CT MNG operates from -55°C to 150°C, while the original part operates from -65°C to 150°C. Applications operating above -55°C experience no temperature-related limitation. Applications requiring operation below -55°C require evaluation of the specific thermal environment and circuit requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the MBRB1535CTHE3_A/I and MBRS1035CT MNG are ROHS3 Compliant and REACH Unaffected, maintaining equivalent environmental compliance for regulated applications.

Q: What is the moisture sensitivity level for the substitute part?

A: The MBRS1035CT MNG carries MSL 1 (Unlimited) moisture sensitivity rating, identical to the original part. This classification permits unlimited shelf life without moisture bake-out requirements prior to soldering.
