SE70PD-M3/87A Equivalent & Substitute Parts

Part Overview

The SE70PD-M3/87A is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount device operates at 200 V DC reverse voltage with an average rectified current of 2.9 A and is housed in a TO-277A (SMPC) package. The part is currently active in production and RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, manufacturing discontinuation, or application-specific requirements within the allowed parameter ranges for this diode category.

Substitute Part Grouping Explanation

Substitute parts for the SE70PD-M3/87A are qualified based on the following electrical and mechanical criteria:

Voltage Compatibility: Substitute parts must maintain the same maximum DC reverse voltage rating of 200 V to ensure safe operation within the application circuit.

Current Rating: Substitute parts must support the required average rectified current of 2.9 A. Parts with higher current ratings (such as 10 A) are acceptable as they provide additional design margin and operational headroom.

Recovery Characteristics: Substitute parts must operate within the standard to fast recovery speed classification (≤500 ns for >200 mA). The main part specifies standard recovery (>500 ns), while faster recovery substitutes are acceptable for improved switching performance.

Reverse Leakage: Substitute parts must maintain reverse leakage current specifications compatible with the application requirements at the rated voltage.

Mounting and Package: Substitute parts must be surface mount devices suitable for automated assembly processes.

Compliance: Substitute parts must maintain RoHS3 compliance and equivalent environmental certifications.

Parameter Comparison

Engineering Selection Recommendations

Voltage and Current Compatibility: The SBR10U200P5-13 substitute maintains the 200 V reverse voltage rating required by the SE70PD-M3/87A application. The substitute's 10 A current rating exceeds the main part's 2.9 A specification, providing additional operational margin without compromising circuit performance.

Recovery Performance: The SBR10U200P5-13 employs Super Barrier technology with fast recovery characteristics (≤500 ns), compared to the standard recovery (>500 ns) of the main part. This represents an improvement in switching speed and reduced reverse recovery losses.

Forward Voltage: The substitute exhibits lower forward voltage drop (880 mV @ 10 A) relative to the main part (1.05 V @ 7 A), resulting in reduced power dissipation and improved thermal performance.

Reverse Leakage: The substitute's reverse leakage current (100 µA @ 200 V) is higher than the main part (20 µA @ 200 V). This difference must be evaluated against application-specific leakage requirements.

Temperature Range: The substitute supports an extended lower operating temperature limit (-65°C versus -55°C), providing broader thermal operating envelope.

Compliance and Certifications: Both parts maintain ROHS3 compliance, unlimited MSL rating, and equivalent environmental certifications (REACH Unaffected, ECCN EAR99).

Package Consideration: The substitute uses PowerDI™ 5 packaging instead of TO-277A (SMPC). PCB layout and thermal management designs must accommodate the different package footprint and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can the SBR10U200P5-13 directly replace the SE70PD-M3/87A without circuit modifications?

A: Electrical substitution is valid based on voltage and current ratings. However, the different package types (PowerDI™ 5 versus TO-277A) require PCB layout redesign. Thermal management characteristics differ between packages and must be re-evaluated for the application.

Q: What is the significance of the higher reverse leakage current in the substitute part?

A: The SBR10U200P5-13 exhibits 100 µA reverse leakage at 200 V compared to 20 µA for the main part. Applications with stringent leakage requirements (such as precision analog circuits or high-impedance paths) must verify this parameter against circuit specifications.

Q: Does the faster recovery time of the substitute provide any advantage?

A: Yes. The SBR10U200P5-13's fast recovery characteristic (≤500 ns) reduces reverse recovery losses compared to the standard recovery main part (>500 ns). This results in lower switching losses and improved efficiency in switching applications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance status, unlimited MSL rating, REACH Unaffected status, and EAR99 ECCN classification.

Q: What design considerations apply to the package change?

A: The PowerDI™ 5 package differs from TO-277A in footprint geometry, lead configuration, and thermal dissipation characteristics. PCB layout, solder reflow profiles, and thermal management designs require re-validation for the new package type.

Q: Is the higher current rating of the substitute a limiting factor?

A: No. The 10 A rating of the SBR10U200P5-13 exceeds the 2.9 A requirement of the application, providing design margin. This does not create compatibility issues for lower-current applications.

Q: How should forward voltage differences be evaluated?

A: The substitute's lower forward voltage (880 mV @ 10 A) reduces power dissipation compared to the main part (1.05 V @ 7 A). This improves thermal performance but requires verification that circuit bias points and voltage regulation remain within specification.
