Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB2080CT-TP is determined by strict equivalence in the following parameters:

• Diode Configuration: Must remain 1 pair common cathode
• Technology: Must remain Schottky
• Package / Case: Must remain TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Current - Average Rectified (Io): Must remain 20 A per diode
• Operating Temperature Range: Must remain -55°C ~ 150°C
• Speed Classification: Must remain fast recovery ≤ 500ns, > 200mA (Io)

Substitute parts may exceed the reverse voltage rating of the main part while maintaining all other electrical and mechanical specifications. Forward voltage characteristics may vary within acceptable engineering tolerances for the same technology and current rating.

Parameter Comparison

Engineering Selection Recommendations

The MBRB20100CT-TP is a direct substitute for the MBRB2080CT-TP based on electrical and mechanical parameter equivalence. The substitute part maintains identical current rating, diode configuration, package form factor, and operating temperature range. The primary difference is an increased reverse voltage rating of 100 V compared to 80 V in the main part, which provides enhanced voltage margin in applications without requiring circuit redesign.

The MBRB20100CT-TP is classified as active product status with ROHS3 compliance and MSL 1 (unlimited moisture sensitivity level), ensuring long-term availability and supply chain stability. The substitute part is available in tape and reel packaging format with significantly higher inventory levels, supporting production requirements.

Frequently Asked Questions (FAQ)

Q: Can the MBRB20100CT-TP replace the MBRB2080CT-TP in existing designs?

A: Yes. The MBRB20100CT-TP maintains identical current rating (20 A), diode configuration (1 pair common cathode), package type (TO-263-3 D2PAK), and operating temperature range (-55°C ~ 150°C). The increased reverse voltage rating (100 V vs. 80 V) is a superset specification that does not require circuit modification.

Q: What is the difference in forward voltage between these parts?

A: The MBRB2080CT-TP specifies 858 mV maximum forward voltage at 10 A, while the MBRB20100CT-TP specifies 850 mV maximum at the same current. Both parts utilize Schottky technology with comparable forward voltage characteristics.

Q: Are the package dimensions identical?

A: Yes. Both parts use TO-263-3, D2PAK (2 Leads + Tab), TO-263AB surface mount package configuration. PCB layout and thermal management considerations remain unchanged.

Q: What is the reverse leakage current specification for each part?

A: The MBRB2080CT-TP specifies 150 µA maximum reverse leakage at 80 V. The MBRB20100CT-TP specifies 150 µA maximum reverse leakage at 100 V. Leakage current is measured at the respective rated reverse voltages.

Q: Why is the MBRB2080CT-TP classified as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The MBRB20100CT-TP is the active equivalent offering superior voltage rating and improved supply availability.

Q: Are there compliance or certification differences?

A: The MBRB20100CT-TP is ROHS3 compliant with MSL 1 rating. Both parts are REACH unaffected and classified under ECCN EAR99 and HTSUS 8541.10.0080.
