MUR415 Equivalent & Substitute Parts

Part Overview

The MUR415 is a general-purpose rectifier diode rated for 150 V DC reverse voltage and 4 A average rectified current, manufactured by onsemi in the SWITCHMODE™ series. The device features fast recovery characteristics with a reverse recovery time of 35 ns and is housed in a DO-201AA/DO-27 axial package for through-hole mounting applications.

The MUR415 is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements. Active alternatives with identical or superior electrical characteristics are available from onsemi and other manufacturers.

Substitute Part Grouping Explanation

Substitution of the MUR415 is determined by the following critical electrical parameters:

Voltage Rating (Vr): Minimum 150 V DC reverse voltage
Current Rating (Io): Minimum 4 A average rectified current
Speed Classification: Fast recovery characteristics (≤ 500ns)
Reverse Recovery Time (trr): Maximum 35 ns
Mounting Configuration: Through-hole axial or compatible package
Operating Temperature Range: Support for -65°C to 175°C junction temperature

Substitute parts are grouped into two categories:

Direct Equivalent (Same Manufacturer): MUR415G is the active production equivalent manufactured by onsemi with identical electrical specifications and RoHS3 compliance.

Cross-Manufacturer Alternatives: BYV98-150-TR, BYV98-150-TAP, BYV28-150-TAP, and STTH302 meet or exceed the core electrical requirements. These parts utilize avalanche or standard technology with compatible voltage and current ratings. Package variations (SOD-64, DO-201AD) accommodate different board layouts while maintaining electrical compatibility.

Engineering Selection Recommendations

Primary Recommendation: MUR415G

MUR415G is the direct active equivalent manufactured by onsemi. It provides identical electrical specifications to the MUR415 with full RoHS3 compliance and active product status. This part is suitable for direct replacement in existing designs without circuit modification. The MUR415G maintains the same DO-201AA/DO-27 axial package footprint and operating temperature range.

Secondary Recommendations: BYV98-150-TR and BYV98-150-TAP

Both BYV98 variants from Vishay meet the core electrical requirements with 150 V reverse voltage and 4 A current rating. These parts feature avalanche technology and are available in active production status with RoHS3 compliance. The primary consideration is package compatibility: BYV98 devices use SOD-64 axial packages rather than DO-201AA. Board layout modifications may be required for mechanical fit. Reverse leakage current is higher (10 µA vs. 5 µA), which is acceptable for most general-purpose rectification applications.

Tertiary Recommendation: BYV28-150-TAP

BYV28-150-TAP provides a 150 V rating with 3.5 A current capacity. This part is suitable for applications where the full 4 A rating is not required. The device features superior reverse leakage characteristics (1 µA) and slightly faster recovery time (30 ns). SOD-64 package compatibility must be verified against board layout requirements.

Alternative Consideration: STTH302

STTH302 from STMicroelectronics offers a higher voltage rating (200 V) with reduced current capacity (3 A). This part is applicable only in designs where the 4 A current requirement can be reduced or where higher voltage margin is beneficial. The DO-201AD package differs from the original DO-201AA specification.

Compliance and Availability

All recommended substitutes carry RoHS3 compliance and REACH unaffected status. All parts are classified as EAR99 for export control purposes. Current inventory levels support immediate procurement for all substitute options.

Frequently Asked Questions (FAQ)

Q: Can MUR415G be used as a direct replacement for MUR415?

A: Yes. MUR415G is the active production equivalent with identical electrical specifications, operating temperature range, and package configuration. No circuit modifications are required.

Q: What is the primary difference between MUR415 and the Vishay BYV98 alternatives?

A: The BYV98 series uses avalanche technology compared to the standard technology of MUR415. Electrically, both meet the 150 V / 4 A requirements with identical reverse recovery time (35 ns). The package differs: BYV98 uses SOD-64 axial format versus MUR415's DO-201AA/DO-27 format. Board layout verification is necessary before substitution.

Q: Is BYV28-150-TAP suitable for applications requiring 4 A?

A: BYV28-150-TAP is rated for 3.5 A average rectified current, which is below the 4 A specification of MUR415. This part is suitable only for applications where the actual current demand does not exceed 3.5 A. Circuit analysis is required to confirm current requirements.

Q: What are the compliance differences between MUR415 and its substitutes?

A: MUR415 is RoHS non-compliant. All substitute parts (MUR415G, BYV98-150-TR, BYV98-150-TAP, BYV28-150-TAP, STTH302) are RoHS3 compliant. For applications subject to RoHS regulations, substitution to any active equivalent is mandatory.

Q: Does package format affect electrical performance?

A: Package format (DO-201AA, SOD-64, DO-201AD) does not affect electrical performance. Package selection is determined by board layout, PCB footprint availability, and mechanical mounting requirements. Electrical characteristics remain consistent across package variants of the same part number base.

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

A: Reverse leakage current affects power dissipation and circuit performance in high-impedance applications. MUR415 specifies 5 µA at 150 V. BYV98 variants specify 10 µA, while BYV28-150-TAP specifies 1 µA. For most general-purpose rectification applications, these differences are negligible. High-impedance or precision analog circuits may require evaluation of leakage impact.

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

A: No. MUR415G maintains the original DO-201AA/DO-27 axial packaging. Vishay BYV98 and BYV28 parts are available in SOD-64 axial format. STTH302 is available in DO-201AD format. Packaging availability varies by supplier and distribution channel. Verify specific packaging requirements with component suppliers.

Q: What is the operating temperature range difference between MUR415 and substitutes?

A: MUR415 and MUR415G support -65°C to 175°C junction temperature. Vishay BYV98 and BYV28 parts support -55°C to 175°C. STTH302 specifies 175°C maximum. For applications requiring operation below -55°C, MUR415G is the only suitable option among active parts.
