Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBRB40100CT are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Variable Parameters (Allowable Differences):

• Current - Average Rectified (Io) (per Diode): Substitutes may have equal or higher current ratings
• Voltage - Forward (Vf) (Max) @ If: Substitutes may have lower forward voltage drop
• Current - Reverse Leakage @ Vr: Substitutes may have lower reverse leakage
• Operating Temperature - Junction (Max): Substitutes may have higher maximum junction temperature

All identified substitute parts maintain identical reverse voltage rating, package configuration, and Schottky technology while offering variations in current handling capability and thermal performance.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. Selection among substitute options depends on application-specific requirements:

STPS10H100CG-TR (STMicroelectronics): This substitute provides the lowest reverse leakage current (3.5 µA @ 100 V) and lowest forward voltage drop (730 mV @ 5 A) among the alternatives. The maximum junction temperature rating of 175°C exceeds the MBRB40100CT specification. This option is suitable for applications prioritizing low power dissipation and minimal leakage characteristics.

VS-16CTQ100S-M3 (Vishay): This substitute offers 8 A current rating with a maximum junction temperature of 175°C. The forward voltage drop of 720 mV @ 8 A is comparable to the STMicroelectronics option. This part is available in Tube packaging, which may affect procurement logistics compared to Tape & Reel formats.

VS-43CTQ100STRLHM3 (Vishay): This substitute matches the MBRB40100CT forward voltage specification (810 mV @ 20 A) and reverse leakage current (1 mA @ 100 V) while providing a 20 A current rating. The part includes AEC-Q101 automotive qualification and operates across the extended temperature range of -55 to 175°C. This option is appropriate for automotive applications and high-current rectification circuits.

Frequently Asked Questions (FAQ)

Q: Can STPS10H100CG-TR be used as a direct replacement for MBRB40100CT?

A: STPS10H100CG-TR is electrically compatible as a substitute. Both devices share identical reverse voltage rating (100 V), diode configuration (1 pair common cathode), Schottky technology, and TO-263-3 D2PAK package. The STPS10H100CG-TR provides superior reverse leakage performance (3.5 µA vs. 1 mA) and lower forward voltage drop (730 mV @ 5 A vs. 880 mV @ 20 A). Packaging differs (Cut Tape & Digi-Reel® vs. Tape & Reel), which may affect procurement and assembly processes.

Q: What are the key differences between VS-16CTQ100S-M3 and VS-43CTQ100STRLHM3?

A: Both Vishay parts maintain 100 V reverse voltage rating and TO-263-3 D2PAK package compatibility. The primary differences are current rating (8 A vs. 20 A), forward voltage drop (720 mV @ 8 A vs. 810 mV @ 20 A), and automotive qualification (VS-43CTQ100STRLHM3 includes AEC-Q101 certification). The VS-43CTQ100STRLHM3 matches the MBRB40100CT forward voltage specification at 20 A operation. Packaging format differs (Tube vs. Tape & Reel).

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all identified substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the MBRB40100CT environmental specifications.

Q: Does package format affect electrical performance?

A: Package format (Tape & Reel, Cut Tape & Digi-Reel®, or Tube) does not affect electrical performance. Format differences impact procurement, storage, and assembly handling procedures only.

Q: Which substitute part has the lowest reverse leakage current?

A: STPS10H100CG-TR exhibits the lowest reverse leakage current at 3.5 µA @ 100 V, compared to 1 mA for MBRB40100CT and VS-43CTQ100STRLHM3, and 550 µA for VS-16CTQ100S-M3.

Q: Can VS-43CTQ100STRLHM3 be used in automotive applications?

A: Yes, VS-43CTQ100STRLHM3 carries AEC-Q101 automotive qualification and is designated as Automotive grade, making it suitable for automotive circuit applications.

Q: What is the maximum junction temperature for each part?

A: MBRB40100CT operates to 150°C maximum junction temperature. STPS10H100CG-TR, VS-16CTQ100S-M3, and VS-43CTQ100STRLHM3 all operate to 175°C maximum junction temperature, providing 25°C additional thermal margin.
