Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent):

VS-10ETF04S-M3 is the appropriate selection when maintaining identical electrical specifications is required. This part is manufactured by the same supplier (Vishay General Semiconductor - Diodes Division) and shares the base product number 10ETF04. The part is active and RoHS3 compliant, addressing regulatory compliance requirements. The reverse recovery time specification of 200 ns is within the fast recovery classification and acceptable for applications designed for the original 10ETF04STRL. Packaging is supplied in Tube format rather than Tape & Reel.

For Performance Enhancement (Current Upgrade):

STTH30R04G and STTH30R04G-TR are suitable when circuit design permits increased current capacity. Both parts maintain the 400 V reverse voltage rating and D2PAK package compatibility. The 30 A current rating provides 3× the capacity of the original part, with improved reverse recovery time (100 ns) and significantly reduced reverse leakage current (15 µA). Both parts are active products with RoHS3 compliance and extended operating temperature range to 175°C. Selection between these two depends on packaging requirements: STTH30R04G is supplied in Tube format, while STTH30R04G-TR is supplied in Cut Tape (CT) & Digi-Reel® format.

Compliance Considerations:

The original 10ETF04STRL is RoHS non-compliant and obsolete. All substitute parts (VS-10ETF04S-M3, STTH30R04G, STTH30R04G-TR) are RoHS3 compliant and active products, supporting transition to current regulatory standards.

Frequently Asked Questions (FAQ)

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

A: Yes. VS-10ETF04S-M3 is a parametric equivalent with identical voltage (400 V), current (10 A), forward voltage (1.2 V @ 10 A), and package specifications (TO-263AB D2PAK). Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share the base product number 10ETF04. The primary differences are product status (active versus obsolete), RoHS compliance (RoHS3 versus non-compliant), and packaging format (Tube versus Tape & Reel).

Q: What is the difference between the Vishay VS-10ETF04S-M3 and the STMicroelectronics STTH30R04G?

A: VS-10ETF04S-M3 maintains the original 10 A current rating, while STTH30R04G is rated for 30 A. Both maintain 400 V reverse voltage and D2PAK package compatibility. STTH30R04G offers improved performance with faster reverse recovery time (100 ns versus 200 ns) and lower reverse leakage current (15 µA versus 100 µA). STTH30R04G is suitable for applications requiring higher current capacity or improved switching characteristics.

Q: Are the STTH30R04G and STTH30R04G-TR electrically identical?

A: Yes. STTH30R04G and STTH30R04G-TR are electrically identical, both manufactured by STMicroelectronics with identical electrical specifications. The difference is packaging format: STTH30R04G is supplied in Tube, while STTH30R04G-TR is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly line requirements and packaging preferences.

Q: Can I use a 30 A rated diode (STTH30R04G) in a circuit designed for 10 A (10ETF04STRL)?

A: Yes. A higher current-rated diode can be used in applications designed for lower current. The 30 A rating indicates the diode can safely conduct up to 30 A; operating at 10 A or below is within specification. The improved reverse recovery time and lower leakage current of the STTH30R04G may provide performance benefits. Thermal management and PCB layout should be verified to ensure adequate heat dissipation for the specific application.

Q: What is the impact of the different reverse recovery times (145 ns, 200 ns, 100 ns)?

A: Reverse recovery time (trr) affects switching speed and switching losses. The original 10ETF04STRL has trr of 145 ns, VS-10ETF04S-M3 has 200 ns, and both STTH30R04G variants have 100 ns. All three are classified as fast recovery diodes (≤ 500 ns). Lower trr values result in faster switching and reduced switching losses, beneficial in high-frequency applications. The choice depends on circuit operating frequency and thermal requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. VS-10ETF04S-M3, STTH30R04G, and STTH30R04G-TR are all RoHS3 compliant. The original 10ETF04STRL is RoHS non-compliant. For applications requiring RoHS compliance, any of the three substitute parts are acceptable.

Q: What packaging options are available for these diodes?

A: 10ETF04STRL is supplied in Tape & Reel (TR). VS-10ETF04S-M3 is supplied in Tube. STTH30R04G is supplied in Tube. STTH30R04G-TR is supplied in Cut Tape (CT) & Digi-Reel®. Selection should align with assembly equipment and production requirements.
