MBRF2080CTHC0G Equivalent & Substitute Parts

Part Overview

The MBRF2080CTHC0G is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as 1 pair common cathode with 80 V reverse voltage rating and 20 A average rectified current per diode. The device is packaged in TO-220-3 Full Pack with isolated tab for through-hole mounting applications. This part maintains Active product status and carries AEC-Q101 automotive qualification with ROHS3 compliance.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement in circuit applications while maintaining the same package footprint and thermal characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBRF2080CTHC0G is determined by the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 80 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack, Isolated Tab
• Operating Temperature Range: -55°C to 150°C

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Equal or greater than 20 A
• Voltage - Forward (Vf) (Max): Equal or lower than 1 V at rated current
• Current - Reverse Leakage @ Vr: Equal or lower than 100 µA @ 80 V

The VFT3080C-E3/4W from Vishay General Semiconductor qualifies as a substitute part. While the current rating is reduced to 15 A, this represents a derating condition that does not prevent substitution in applications where the actual circuit current demand does not exceed 15 A. The forward voltage and reverse leakage characteristics remain within acceptable parameters for functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: MBRF2080CTHC0G

The MBRF2080CTHC0G is the specified component with full 20 A current rating per diode. This part carries AEC-Q101 automotive qualification and maintains Active product status. Selection of this part is appropriate for applications requiring the full 20 A current capacity within the -55°C to 150°C operating range.

Substitute Part: VFT3080C-E3/4W

The VFT3080C-E3/4W from Vishay General Semiconductor qualifies as a functional substitute when circuit design permits operation at 15 A per diode. This part maintains identical package geometry (TO-220-3 Full Pack, Isolated Tab), reverse voltage rating (80 V), and temperature range (-55°C to 150°C). Both parts carry ROHS3 compliance and Active product status.

The VFT3080C-E3/4W exhibits lower forward voltage (820 mV @ 15 A versus 1 V @ 20 A) and higher reverse leakage current (700 µA @ 80 V versus 100 µA @ 80 V). These characteristics remain within acceptable parameters for Schottky diode array applications. The substitute part is suitable for designs where the actual circuit current demand does not exceed 15 A per diode.

Frequently Asked Questions (FAQ)

Q: Can the VFT3080C-E3/4W replace the MBRF2080CTHC0G in all applications?

A: The VFT3080C-E3/4W is suitable for replacement only in applications where the circuit current demand does not exceed 15 A per diode. The substitute part has a lower current rating (15 A versus 20 A). If the application requires the full 20 A capacity, the MBRF2080CTHC0G must be used.

Q: Are the package dimensions identical between these parts?

A: Both parts use the TO-220-3 Full Pack with isolated tab package. The mechanical footprint and mounting characteristics are identical, allowing direct board-level substitution without layout modification.

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

A: The MBRF2080CTHC0G has a maximum forward voltage of 1 V at 20 A, while the VFT3080C-E3/4W has a maximum forward voltage of 820 mV at 15 A. The substitute part exhibits lower forward voltage, which may result in reduced power dissipation in the diode element.

Q: Do both parts meet automotive qualification requirements?

A: The MBRF2080CTHC0G carries AEC-Q101 automotive qualification. The VFT3080C-E3/4W is manufactured by Vishay General Semiconductor and maintains Active product status with ROHS3 compliance. Verification of specific automotive qualification requirements for the substitute part should be performed against application specifications.

Q: What is the significance of the reverse leakage current difference?

A: The MBRF2080CTHC0G has a reverse leakage current of 100 µA @ 80 V, while the VFT3080C-E3/4W has 700 µA @ 80 V. The higher leakage in the substitute part may affect circuit performance in applications sensitive to reverse current, particularly in high-impedance circuits or at elevated temperatures.

Q: Are both parts RoHS compliant?

A: Both the MBRF2080CTHC0G and VFT3080C-E3/4W are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic component manufacturing and use.
