Key Parameters

Substitute Part Grouping Explanation

Substitution of the 10ETF04S is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 400 V minimum
• Current - Average Rectified (Io): 10 A minimum
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Allowable Variations:

• Reverse Recovery Time (trr): May be lower than 145 ns
• Current - Reverse Leakage @ Vr: May be lower than 100 µA @ 400 V
• Operating Temperature - Junction: May extend beyond -40°C to 150°C range
• Forward Voltage (Vf): May vary if rated current capacity is higher
• Product Status: Active parts are preferred over obsolete classifications
• RoHS Compliance: ROHS3 compliant parts are preferred for regulatory alignment

Substitute parts must maintain or exceed the electrical performance of the 10ETF04S while maintaining identical mechanical compatibility through the D2PAK package footprint.

Engineering Selection Recommendations

VS-10ETF04STRL-M3 (Vishay General Semiconductor - Diodes Division)

This part is a parametric equivalent to the 10ETF04S with identical electrical ratings: 400 V reverse voltage, 10 A average rectified current, and 1.2 V forward voltage at 10 A. The reverse recovery time is 200 ns, which remains within the fast recovery classification. The primary advantages are active product status and ROHS3 compliance, addressing regulatory requirements. The part is supplied in Tape & Reel packaging, suitable for automated assembly processes. This substitute maintains full electrical and mechanical compatibility with the 10ETF04S.

STTH30R04G and STTH30R04G-TR (STMicroelectronics)

These parts are manufacturer-recommended alternatives with enhanced electrical performance. Both maintain the 400 V reverse voltage rating but increase the current capacity to 30 A, providing design margin for higher-load applications. The reverse recovery time of 100 ns is superior to the 10ETF04S, and reverse leakage current is reduced to 15 µA at 400 V. Operating temperature range extends to 175°C, supporting higher thermal environments. Both parts are ROHS3 compliant and maintain D2PAK package compatibility. STTH30R04G is supplied in Tube packaging, while STTH30R04G-TR is supplied in Cut Tape and Digi-Reel formats for different procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can the VS-10ETF04STRL-M3 be used as a direct replacement for the 10ETF04S?

A: Yes. The VS-10ETF04STRL-M3 is a parametric equivalent with identical voltage and current ratings, forward voltage characteristics, and D2PAK package footprint. The reverse recovery time of 200 ns remains within the fast recovery specification. The primary difference is active product status and ROHS3 compliance.

Q: What is the advantage of using STTH30R04G or STTH30R04G-TR over the VS-10ETF04STRL-M3?

A: The STMicroelectronics parts provide higher current capacity (30 A versus 10 A), faster reverse recovery time (100 ns versus 145 ns or 200 ns), and lower reverse leakage current (15 µA versus 100 µA). These characteristics offer improved thermal performance and reduced switching losses. The extended operating temperature range to 175°C supports higher ambient conditions.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the TO-263-3 D2PAK (2 Leads + Tab) package, ensuring identical mechanical compatibility and PCB footprint with the 10ETF04S.

Q: What is the difference between STTH30R04G and STTH30R04G-TR?

A: Both parts have identical electrical specifications. The difference is packaging format: STTH30R04G is supplied in Tube packaging, while STTH30R04G-TR is supplied in Cut Tape and Digi-Reel formats. Selection depends on assembly process requirements and procurement volume.

Q: Is RoHS compliance a factor in selecting a substitute?

A: The 10ETF04S is RoHS non-compliant. All substitute parts (VS-10ETF04STRL-M3, STTH30R04G, and STTH30R04G-TR) are ROHS3 compliant, meeting current regulatory requirements for electronic components in restricted substance directives.

Q: Can the STTH30R04G parts be used in applications rated for 10 A?

A: Yes. The STTH30R04G and STTH30R04G-TR are rated for 30 A average rectified current, which exceeds the 10 A requirement of the original 10ETF04S. These parts operate within specification at lower current levels and provide design margin for future load increases.

Q: What is the impact of the different reverse recovery times on circuit performance?

A: The 10ETF04S has a reverse recovery time of 145 ns. The VS-10ETF04STRL-M3 has 200 ns, and the STMicroelectronics parts have 100 ns. All remain within the fast recovery classification (≤ 500 ns). Faster recovery times reduce switching losses and electromagnetic interference in high-frequency applications. The STMicroelectronics parts offer superior performance in this regard.
