Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRD320G is determined by equivalence across the following critical electrical and mechanical parameters:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 20 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 600 mV @ 3 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 200 µA @ 20 V
• Technology: Schottky

Mechanical Parameters:

• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount

The VS-MBRD320-M3 manufactured by Vishay General Semiconductor - Diodes Division satisfies all specified electrical and mechanical parameters, establishing it as a direct equivalent substitute for the obsolete MBRD320G.

Parameter Comparison

Engineering Selection Recommendations

The VS-MBRD320-M3 is the qualified substitute for the obsolete MBRD320G. Both components are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for current procurement and manufacturing environments.

The VS-MBRD320-M3 maintains active product status with Vishay General Semiconductor - Diodes Division, ensuring ongoing availability and supply chain continuity. The substitute part is supplied in tube packaging with 30,300 pieces in current inventory.

The operating temperature range of the VS-MBRD320-M3 (-40°C ~ 150°C) is narrower than the MBRD320G (-65°C ~ 150°C) at the lower temperature extreme. Applications requiring operation below -40°C junction temperature must evaluate this specification difference against system requirements.

All electrical parameters, including reverse voltage, rectified current, forward voltage drop, recovery speed, and reverse leakage current, are identical between the two parts. The mechanical package and mounting type are equivalent, supporting direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the VS-MBRD320-M3 be used as a direct replacement for the MBRD320G in existing designs?

A: The VS-MBRD320-M3 is electrically and mechanically equivalent to the MBRD320G across all specified parameters. PCB footprints and circuit connections are compatible. The lower operating temperature minimum (-40°C versus -65°C) must be evaluated for applications requiring extended low-temperature operation.

Q: What is the primary reason for substituting the MBRD320G?

A: The MBRD320G is classified as obsolete. The VS-MBRD320-M3 provides an active, in-stock alternative from a qualified manufacturer with identical electrical specifications and package configuration.

Q: Are there differences in forward voltage characteristics between these parts?

A: Both parts specify 600 mV maximum forward voltage at 3 A. No difference exists in this parameter.

Q: Do both parts meet current regulatory compliance standards?

A: Both the MBRD320G and VS-MBRD320-M3 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement and manufacturing.

Q: What is the package configuration for both parts?

A: Both parts use the TO-252-3 DPAK package (2 Leads + Tab), designated SC-63. This is a surface mount package suitable for automated assembly processes.

Q: Is there a difference in reverse leakage current between the two parts?

A: Both parts specify 200 µA maximum reverse leakage current at 20 V. No difference exists in this parameter.

Q: What recovery speed is specified for these Schottky diodes?

A: Both parts are rated for fast recovery with speed ≤ 500ns at currents greater than 200mA, meeting fast switching requirements in power conversion applications.
