Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB40150CT is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 150 V
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

The substitute part VB30150C-M3/8W from Vishay General Semiconductor - Diodes Division satisfies all critical matching parameters. Both components share identical reverse voltage ratings, package configurations, mounting types, temperature operating ranges, and speed classifications. The substitute maintains the same diode array configuration and Schottky technology foundation required for functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the MBRB40150CT and VB30150C-M3/8W are Active products with full ROHS3 compliance and unlimited moisture sensitivity classification. Selection between these components should be based on the following factors:

MBRB40150CT (SMC Diode Solutions): Select this component when SMC Diode Solutions is the preferred manufacturer or when existing supply chain relationships with SMC are established. This part demonstrates lower reverse leakage current at 1 mA @ 150 V and lower forward voltage drop at 950 mV @ 20 A, which may provide advantages in applications requiring minimal power dissipation.

VB30150C-M3/8W (Vishay): Select this component when Vishay is the preferred manufacturer or when supply availability from Vishay is prioritized. This part is part of the TMBS® series and demonstrates lower reverse leakage current at 200 µA @ 150 V. The specified current rating of 15 A per diode provides explicit current handling capacity documentation.

Both components are suitable for applications requiring 150 V Schottky diode arrays in Surface Mount TO-263-3 D2PAK packages with operating temperatures from -55°C to 150°C. Compliance certifications and moisture sensitivity levels are equivalent between both options.

Frequently Asked Questions (FAQ)

Q: Can VB30150C-M3/8W be used as a direct replacement for MBRB40150CT?

A: Yes. Both components share identical diode configuration (1 Pair Common Cathode), Schottky technology, 150 V reverse voltage rating, TO-263-3 D2PAK package, Surface Mount mounting type, and operating temperature range of -55°C to 150°C. Pin-to-pin compatibility is maintained.

Q: What are the differences in electrical performance between these two parts?

A: The primary electrical differences are forward voltage drop and reverse leakage current. The MBRB40150CT exhibits 950 mV forward voltage @ 20 A and 1 mA reverse leakage @ 150 V. The VB30150C-M3/8W exhibits 1.36 V forward voltage @ 15 A and 200 µA reverse leakage @ 150 V. These differences should be evaluated against specific application requirements for power dissipation and leakage current tolerance.

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

A: Yes. Both the MBRB40150CT and VB30150C-M3/8W are supplied in Tape & Reel (TR) packaging and use identical TO-263-3 D2PAK package configurations with 2 leads plus tab.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited) classification. Both are Active products with current manufacturing status.

Q: What is the significance of the Fast Recovery speed specification?

A: Both components are specified as Fast Recovery diodes with switching speed ≤ 500ns for currents > 200mA (Io). This classification indicates suitability for high-frequency switching applications and power conversion circuits requiring rapid diode turn-off characteristics.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. The identical TO-263-3 D2PAK package and pin configuration allow direct PCB footprint compatibility. No layout modifications are required for substitution.
