MSR1560 Equivalent & Substitute Parts

Part Overview

The MSR1560 is a general-purpose rectifier diode rated for 600 V DC reverse voltage and 15 A average rectified current in a Through Hole TO-220-2 package. Manufactured by onsemi under the SWITCHMODE™ series, this component is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute diodes must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating available packaging options.

Substitute Part Grouping Explanation

Substitute parts for the MSR1560 are classified based on electrical parameter compatibility within the following criteria:

Direct Equivalent (Identical Specifications): Parts that maintain the same voltage rating (600 V), current rating (15 A), package type (TO-220-2), and thermal characteristics qualify as direct equivalents. These parts are interchangeable without circuit redesign.

Functional Equivalent (Compatible Specifications): Parts that meet or exceed the voltage and current requirements while maintaining the same package footprint and thermal operating range are classified as functional equivalents. These parts accommodate applications where the original specification can be met by higher-rated components.

Partial Equivalent (Derating Required): Parts with reduced current ratings or modified package configurations require circuit evaluation to confirm suitability. These parts may be used in applications where the full 15 A rating is not required.

Key Parameters for Substitution Assessment:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 600 V
Current - Average Rectified (Io): Must equal or exceed 15 A for direct equivalents; lower ratings require application review
Package / Case: TO-220-2 footprint preferred; TO-220AC variants acceptable with mechanical verification
Mounting Type: Through Hole (all candidates meet this requirement)
Operating Temperature Range: Must accommodate -65°C to 150°C minimum

Engineering Selection Recommendations

Direct Equivalent - Recommended Primary Substitute:

MSR1560G (onsemi) is the direct equivalent replacement for the obsolete MSR1560. This part maintains identical electrical specifications: 600 V reverse voltage, 15 A average rectified current, 1.8 V forward voltage at 15 A, and 45 ns reverse recovery time. The MSR1560G is manufactured by the same supplier (onsemi) and carries Active product status with ROHS3 compliance. Packaging is supplied in Tube format. This part provides seamless substitution without circuit modification.

Functional Equivalent - High Performance Alternative:

VS-15ETH06-M3 (Vishay General Semiconductor - Diodes Division) meets all electrical requirements with enhanced performance characteristics. This part maintains 600 V reverse voltage and 15 A current rating while offering superior reverse recovery time (29 ns versus 45 ns) and extended operating temperature range (-65°C to 175°C). Forward voltage is slightly elevated at 2.2 V @ 15 A. The part is ROHS3 compliant and carries Active product status. Supplier device package is TO-220AC, which is mechanically compatible with TO-220-2 footprint applications.

Functional Equivalent - Alternative Selection:

RFV12TG6SGC9 (Rohm Semiconductor) provides 600 V reverse voltage with reduced current rating of 12 A. This part is suitable for applications where the full 15 A rating is not required. Reverse recovery time matches the original specification at 45 ns. Reverse leakage current is superior at 10 µA @ 600 V. The part is ROHS3 compliant with Active product status. Supplier device package is TO-220ACFP.

Partial Equivalent - Derating Application:

IDP08E65D2XKSA1 (Infineon Technologies) provides higher voltage rating (650 V) but reduced current capacity (8 A). This part is suitable only for applications where current requirements do not exceed 8 A. Reverse recovery time is superior at 40 ns. The part is ROHS3 compliant with Active product status and extended operating temperature range (-40°C to 175°C).

Not Recommended:

BYC15-600,127 (WeEn Semiconductors) has reduced reverse voltage rating (500 V) below the 600 V specification of the MSR1560. This part does not meet the minimum voltage requirement and is not suitable for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can MSR1560G be used as a direct replacement for MSR1560?

A: Yes. MSR1560G is the direct equivalent with identical electrical specifications: 600 V reverse voltage, 15 A average rectified current, 1.8 V forward voltage at 15 A, and 45 ns reverse recovery time. Both parts use the same TO-220-2 package footprint. MSR1560G is manufactured by onsemi with Active product status and ROHS3 compliance.

Q: What is the difference between TO-220-2 and TO-220AC packages?

A: Both package types use the same physical footprint and pin configuration for Through Hole mounting applications. TO-220AC is a variant designation used by some manufacturers. Parts specified with TO-220AC supplier device package (such as VS-15ETH06-M3 and BYC15-600,127) are mechanically compatible with TO-220-2 circuit board layouts.

Q: Can VS-15ETH06-M3 replace MSR1560 in all applications?

A: VS-15ETH06-M3 maintains the same 600 V reverse voltage and 15 A current rating as MSR1560, making it electrically compatible. The part offers improved reverse recovery time (29 ns versus 45 ns) and extended temperature range (-65°C to 175°C). Forward voltage is slightly higher at 2.2 V @ 15 A compared to 1.8 V. Circuit thermal analysis should confirm that the higher forward voltage does not exceed design limits.

Q: Why is BYC15-600,127 not recommended as a substitute?

A: BYC15-600,127 has a maximum reverse voltage rating of 500 V, which is below the 600 V specification required by MSR1560. This part does not meet the minimum voltage requirement and cannot be used as a substitute.

Q: Can IDP08E65D2XKSA1 be used in place of MSR1560?

A: IDP08E65D2XKSA1 can be used only in applications where the average rectified current requirement does not exceed 8 A. The part provides higher voltage rating (650 V) and superior reverse recovery time (40 ns), but the reduced current capacity (8 A versus 15 A) requires circuit evaluation to confirm suitability. This part is not suitable for applications requiring the full 15 A rating.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: All recommended substitute parts carry ROHS3 compliance, whereas the original MSR1560 is RoHS non-compliant. ROHS3 compliance indicates the part meets Restriction of Hazardous Substances requirements and is suitable for new designs and production environments with RoHS mandates. This is a compliance advantage of substitute parts over the obsolete original.

Q: How does reverse recovery time affect circuit performance?

A: Reverse recovery time (trr) determines the speed at which the diode transitions from conducting to blocking state. Shorter reverse recovery times reduce switching losses and electromagnetic interference. VS-15ETH06-M3 offers 29 ns (superior), while MSR1560, MSR1560G, and RFV12TG6SGC9 all specify 45 ns. IDP08E65D2XKSA1 provides 40 ns. Selection depends on circuit switching frequency and thermal management requirements.

Q: Are all substitute parts available in the same packaging format?

A: Substitute parts are supplied in Tube packaging format. MSR1560G, VS-15ETH06-M3, BYC15-600,127, IDP08E65D2XKSA1, and RFV12TG6SGC9 are all available in Tube packaging. Inventory availability varies by part number and supplier.
