• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)

Allowable Parameter Variations:

• Current - Average Rectified (Io) (per Diode): Equal or greater than 12.5 A
• Voltage - Forward (Vf) (Max) @ If: May vary based on current rating
• Current - Reverse Leakage @ Vr: May vary within acceptable limits
• Operating Temperature - Junction: May extend beyond -65°C ~ 125°C range
• Product Status: Active or Obsolete

Substitute parts identified below meet these criteria and are electrically and mechanically compatible with the MBRB2535CTLG in standard applications.

Parameter Comparison

Engineering Selection Recommendations

VS-MBRB2535CT-M3 (Vishay): This substitute part is classified as active and provides enhanced current capability at 15 A per diode, exceeding the 12.5 A specification of the MBRB2535CTLG. The extended operating temperature range to 150°C provides additional thermal margin. Both parts maintain identical reverse voltage ratings, package configurations, and fast recovery characteristics. This part is suitable for direct substitution in applications where the higher current rating and active product status are advantageous.

NRVBB2535CTLG (onsemi): This parametric equivalent maintains identical electrical specifications to the MBRB2535CTLG, including current rating, forward voltage, and reverse leakage characteristics. The NRVBB2535CTLG is qualified to AEC-Q101 automotive standards, distinguishing it as an automotive-grade variant. Both parts are obsolete; however, this equivalent provides automotive qualification for applications requiring such compliance.

Frequently Asked Questions (FAQ)

Q: Can the VS-MBRB2535CT-M3 be used as a direct replacement for the MBRB2535CTLG?

A: Yes. Both parts share identical reverse voltage (35 V), diode configuration (1 pair common cathode), technology (Schottky), package (TO-263-3 D2PAK), and fast recovery speed characteristics. The VS-MBRB2535CT-M3 provides higher current capability (15 A vs. 12.5 A) and extended temperature range (-65°C to 150°C vs. -65°C to 125°C), making it electrically and mechanically compatible for direct substitution.

Q: What is the difference between the MBRB2535CTLG and NRVBB2535CTLG?

A: The NRVBB2535CTLG is a parametric equivalent with identical electrical specifications. The primary distinction is automotive qualification: the NRVBB2535CTLG meets AEC-Q101 standards, while the MBRB2535CTLG does not carry this designation. Both are obsolete products from onsemi.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the TO-263-3 (D2PAK) package with 2 leads plus tab configuration, ensuring identical pinout and PCB footprint compatibility.

Q: Does the higher current rating of the VS-MBRB2535CT-M3 affect circuit design?

A: The higher current rating (15 A vs. 12.5 A) does not negatively affect circuit design. The part operates within the same voltage and thermal parameters and provides additional current margin. Thermal management and PCB layout considerations remain consistent with the original design.

Q: What is the significance of the reverse leakage current difference between MBRB2535CTLG and VS-MBRB2535CT-M3?

A: The VS-MBRB2535CT-M3 exhibits lower reverse leakage (200 µA @ 35 V vs. 10 mA @ 35 V). Lower leakage current reduces standby power consumption and heat generation, providing a performance advantage in applications sensitive to leakage characteristics.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and handling requirements for standard manufacturing processes.
