MBRD660 Equivalent & Substitute Parts

Part Overview

The MBRD660 is a Schottky rectifier diode rated for 60V DC reverse voltage and 6A average rectified current, packaged in a Surface Mount DPAK (TO-252-3) configuration. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance is required within the same voltage class and package family, or when higher current ratings are acceptable for the application circuit design.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRD660 is based on the following critical electrical and mechanical parameters:

Voltage Compatibility: The substitute part must maintain the same maximum DC reverse voltage rating of 60V to ensure circuit protection and reliability.

Package Compatibility: The substitute part must use the same physical package designation (TO-252-3, DPAK with 2 Leads + Tab, SC-63) to ensure mechanical fit and thermal performance in the PCB layout.

Technology Class: Both parts must employ Schottky diode technology to maintain consistent forward voltage characteristics and fast recovery speed performance.

Current Rating: The substitute part may exceed the 6A average rectified current specification, as higher current ratings are backward compatible within the same voltage and package class.

Speed Specification: Fast recovery performance (≤ 500ns, > 200mA) must be maintained.

Compliance Requirements: RoHS3 compliance and MSL Level 1 are required for manufacturing and environmental standards.

The identified substitute part V35PWM60HM3/I meets all mandatory compatibility criteria while providing enhanced current handling capability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MBRD660): Use when the application requires the exact 6A current rating specification and the lower capacitance characteristic (400pF) is a design requirement. Both parts are Active status products with RoHS3 compliance and MSL Level 1 rating, ensuring equivalent manufacturing and environmental compliance.

Substitute Selection (V35PWM60HM3/I): Use when higher current capacity (35A) is required within the same 60V voltage class. This substitute maintains identical voltage rating, package footprint, and fast recovery speed performance. The substitute provides extended operating temperature range (-40°C to 175°C versus -55°C to 150°C) and carries AEC-Q101 automotive qualification. The higher reverse leakage current (2.1 mA versus 1 mA) and capacitance (3340pF versus 400pF) must be evaluated against circuit requirements.

Both parts are RoHS3 compliant and carry MSL Level 1 rating, confirming equivalent compliance status for manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can V35PWM60HM3/I directly replace MBRD660 in all applications?

A: Direct replacement is possible from a mechanical and voltage standpoint, as both parts share the same TO-252-3 DPAK package and 60V rating. However, the substitute's higher current rating (35A), increased capacitance (3340pF), and higher reverse leakage current (2.1 mA) must be evaluated against specific circuit requirements. The substitute is suitable for applications where the original 6A rating is not a limiting constraint.

Q: Are the package dimensions identical between MBRD660 and V35PWM60HM3/I?

A: Both parts use the TO-252-3 DPAK package designation with 2 Leads + Tab (SC-63). The MBRD660 uses standard DPAK, while the V35PWM60HM3/I uses SlimDPAK variant. Both maintain the same footprint compatibility for PCB layout purposes.

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

A: The MBRD660 specifies 750 mV maximum forward voltage at 6A, while the V35PWM60HM3/I specifies 770 mV maximum at 35A. The 20 mV difference reflects the higher current rating of the substitute. At lower operating currents, the V35PWM60HM3/I forward voltage will be lower than specified.

Q: Does the higher capacitance of V35PWM60HM3/I affect circuit performance?

A: The V35PWM60HM3/I capacitance is 3340pF at 4V compared to 400pF at 5V for the MBRD660. Higher capacitance may affect high-frequency switching performance and should be evaluated in circuits sensitive to junction capacitance effects.

Q: Are both parts RoHS3 compliant?

A: Yes, both MBRD660 and V35PWM60HM3/I are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, confirming equivalent environmental and manufacturing compliance.

Q: What is the temperature operating range difference?

A: The MBRD660 operates from -55°C to 150°C junction temperature, while the V35PWM60HM3/I operates from -40°C to 175°C. The substitute provides a wider upper temperature range, suitable for high-temperature applications.

Q: Does the substitute have automotive qualification?

A: Yes, the V35PWM60HM3/I carries AEC-Q101 automotive qualification, while the MBRD660 does not list this certification. This qualification is relevant for automotive and industrial applications requiring automotive-grade component standards.
