VS-10ETF04STRR-M3 Equivalent & Substitute Parts

Part Overview

The VS-10ETF04STRR-M3 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount device operates at 400 V DC reverse voltage with a 10 A average rectified current rating and features fast recovery characteristics with a 200 ns reverse recovery time. The component is housed in a TO-263AB (D2PAK) package and is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory availability changes, or when higher performance specifications within the same package footprint become necessary for system optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VS-10ETF04STRR-M3 are identified based on the following critical parameters that determine functional compatibility:

Voltage Rating Compatibility: The substitute part must maintain the same maximum DC reverse voltage specification of 400 V to ensure safe operation within the intended circuit application.

Package Compatibility: The substitute part must use the TO-263-3 D2PAK package format to ensure mechanical and thermal compatibility with existing PCB layouts and thermal management designs.

Technology Classification: Both the main part and substitute must operate as fast recovery rectifier diodes with reverse recovery time specifications within the ≤ 500 ns range for > 200 mA current levels.

Compliance Requirements: All substitute parts must maintain RoHS3 compliance and REACH unaffected status to satisfy regulatory and supply chain requirements.

Current Rating Consideration: While the substitute part may exceed the current rating of the main part, it must not fall below the 10 A specification to ensure adequate performance margin in the application circuit.

STTH30R04G as Substitute for VS-10ETF04STRR-M3

The STTH30R04G manufactured by STMicroelectronics is a qualified substitute for the VS-10ETF04STRR-M3. Both components share identical voltage ratings (400 V DC reverse), identical package specifications (TO-263-3 D2PAK), and identical fast recovery speed classifications. Both devices maintain Active product status with full RoHS3 compliance and unlimited moisture sensitivity ratings.

The STTH30R04G provides enhanced performance characteristics within the same physical footprint. The substitute part delivers a higher average rectified current rating of 30 A compared to the main part's 10 A specification, providing additional current capacity margin. The STTH30R04G exhibits superior reverse recovery time performance at 100 ns versus the main part's 200 ns, resulting in reduced switching losses and improved efficiency in high-frequency applications. Reverse leakage current is significantly lower at 15 µA compared to 100 µA in the main part.

Both components satisfy identical regulatory and compliance requirements, ensuring seamless integration into supply chains and manufacturing processes without additional qualification steps.

Frequently Asked Questions (FAQ)

Q: Can the STTH30R04G directly replace the VS-10ETF04STRR-M3 in existing circuit designs?

A: Yes. Both components share identical voltage ratings (400 V), identical package specifications (TO-263-3 D2PAK), and identical fast recovery speed classifications. The physical footprint and thermal characteristics are compatible. The STTH30R04G provides higher current capacity (30 A versus 10 A), which does not create compatibility issues in applications designed for the 10 A part.

Q: What are the key differences between these two diodes?

A: The primary differences are manufacturer origin and performance specifications. The STTH30R04G provides 30 A current rating versus 10 A, faster reverse recovery time (100 ns versus 200 ns), and lower reverse leakage current (15 µA versus 100 µA). Forward voltage drop is higher at 1.45 V @ 30 A compared to 1.2 V @ 10 A, reflecting the higher current rating specification point.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both the VS-10ETF04STRR-M3 and STTH30R04G are RoHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity ratings (MSL 1). Both components satisfy identical regulatory requirements for industrial and commercial applications.

Q: Does the higher current rating of the STTH30R04G affect thermal management requirements?

A: The STTH30R04G and VS-10ETF04STRR-M3 share identical TO-263-3 D2PAK package specifications, ensuring identical thermal interface characteristics and PCB footprint compatibility. Thermal management design remains unchanged when substituting between these parts.

Q: What is the significance of the faster reverse recovery time in the STTH30R04G?

A: The STTH30R04G reverse recovery time of 100 ns is faster than the VS-10ETF04STRR-M3 at 200 ns. Faster reverse recovery reduces switching losses and improves efficiency in high-frequency rectification applications. This represents an enhancement when substituting the STTH30R04G into existing designs.

Q: Can the VS-10ETF04STRR-M3 be used in applications requiring the STTH30R04G specifications?

A: No. Applications requiring the 30 A current rating, 100 ns reverse recovery time, or lower reverse leakage characteristics of the STTH30R04G cannot be satisfied by the VS-10ETF04STRR-M3, which is rated for 10 A maximum current and 200 ns reverse recovery time.
