MBRF760-E3/45 Equivalent & Substitute Parts

Part Overview

The MBRF760-E3/45 is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 60V DC reverse voltage and 7.5A average rectified current in a through-hole TO-220-2 package configuration. This part is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility within the specified voltage and current parameters while accommodating different packaging and mounting technologies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBRF760-E3/45 is determined by the following critical parameters:

Voltage Rating: All substitute parts must maintain a DC reverse voltage (Vr) rating of 60V or greater to ensure safe operation within the original circuit specifications.

Current Rating: Substitute parts must support an average rectified current (Io) of 7.5A or greater. Parts with lower current ratings cannot be considered direct substitutes.

Technology: All substitutes must employ Schottky diode technology to maintain fast recovery characteristics and forward voltage performance consistent with the original part.

Speed Characteristics: Fast recovery performance (≤ 500ns, > 200mA) is mandatory for functional equivalence.

Compliance: All substitute parts must maintain ROHS3 compliance and REACH unaffected status to meet regulatory requirements.

The two identified substitute parts differ in mounting technology (surface mount vs. through hole) and current capacity, requiring evaluation based on specific circuit requirements and PCB design constraints.

Parameter Comparison

Engineering Selection Recommendations

STPS10L60CFP (STMicroelectronics): This part maintains through-hole mounting compatibility with the original MBRF760-E3/45, eliminating PCB redesign requirements. The STPS10L60CFP is configured as a 1 Pair Common Cathode diode array in TO-220-3 Full Pack, providing 5A per diode at 60V. This part is active in production status and ROHS3 compliant. The lower reverse leakage current (220 µA @ 60 V) compared to the original part represents improved performance. However, the 5A per-diode rating is below the original 7.5A specification, requiring thermal and circuit analysis to confirm suitability for applications demanding the full original current capacity.

V8P6-M3/87A (Vishay General Semiconductor - Diodes Division): This part requires PCB redesign due to surface-mount TO-277 packaging, incompatible with through-hole TO-220-2 footprints. The V8P6-M3/87A is rated for 4.2A average rectified current at 60V, which is significantly below the original 7.5A specification. This part is active in production status and ROHS3 compliant. The improved forward voltage performance (610 mV @ 8 A) and lower junction temperature minimum (-40°C vs. -65°C) may be acceptable for specific applications, but the reduced current capacity presents a fundamental limitation for high-current circuit requirements.

Selection between these alternatives depends on circuit current requirements, thermal management capabilities, and PCB design flexibility. Through-hole mounting compatibility favors STPS10L60CFP for direct replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the V8P6-M3/87A directly replace the MBRF760-E3/45 without PCB modification?

A: No. The V8P6-M3/87A uses surface-mount TO-277 packaging, while the MBRF760-E3/45 uses through-hole TO-220-2 packaging. PCB redesign is required for this substitution.

Q: Is the STPS10L60CFP suitable for all applications using the MBRF760-E3/45?

A: The STPS10L60CFP maintains 60V voltage rating and through-hole mounting compatibility. However, the 5A per-diode current rating is lower than the original 7.5A specification. Circuit analysis is required to confirm suitability for applications operating at or near the original current limits.

Q: What is the significance of the diode array configuration in the STPS10L60CFP?

A: The STPS10L60CFP is a 1 Pair Common Cathode configuration, meaning two diodes share a common cathode connection. This differs from the single-diode MBRF760-E3/45. Circuit topology must accommodate this configuration.

Q: Do all substitute parts meet the same compliance standards as the original part?

A: Yes. Both substitute parts are ROHS3 compliant and REACH unaffected, matching the original MBRF760-E3/45 compliance status.

Q: What is the impact of different reverse leakage current values?

A: The STPS10L60CFP exhibits lower reverse leakage (220 µA @ 60 V) compared to the MBRF760-E3/45 (500 µA @ 60 V), representing improved performance. The V8P6-M3/87A shows slightly higher leakage (600 µA @ 60 V), which remains within acceptable ranges for most applications.

Q: Are there temperature range differences between the original and substitute parts?

A: Yes. The MBRF760-E3/45 operates from -65°C to 150°C, while the V8P6-M3/87A operates from -40°C to 150°C. The STPS10L60CFP specifies 150°C maximum without a minimum. Applications requiring operation below -40°C must use the original part or confirm compatibility with the substitute's actual minimum operating temperature.

Q: What does "Fast Recovery ≤ 500ns, > 200mA (Io)" mean?

A: This specification indicates that all parts achieve fast recovery switching characteristics (recovery time ≤ 500 nanoseconds) when forward current exceeds 200mA. This ensures consistent high-frequency performance across all three parts.
