Equivalent & Substitute Parts for 10ETS08

Part Overview

The 10ETS08 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 800 V DC reverse voltage and 10 A average rectified current in a through-hole TO-220AC package. This component is classified as obsolete, making identification of suitable substitute parts necessary for ongoing design support and procurement continuity. The part operates across a junction temperature range of -40°C to 150°C and exhibits standard recovery characteristics typical of conventional rectifier diodes.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 10ETS08 is determined by compatibility across the following critical parameters:

Package and Mounting Compatibility: Both the main part and substitute must use through-hole mounting in the TO-220-2 package configuration to ensure mechanical and thermal interface compatibility with existing PCB designs.

Voltage Rating: The substitute part must meet or exceed the 800 V DC reverse voltage specification of the 10ETS08. A higher voltage rating provides design margin and does not compromise circuit function.

Current Rating: The substitute part must support the 10 A average rectified current requirement. A lower current rating is not acceptable; equal or higher ratings are permissible.

Forward Voltage Characteristics: Forward voltage drop at the specified current level influences power dissipation and thermal management. Substitute parts with comparable or lower forward voltage drops are acceptable.

Reverse Leakage Current: Lower reverse leakage current values indicate superior device quality and reduced standby power consumption.

Recovery Speed: Standard or faster recovery characteristics are acceptable for general-purpose rectification applications.

Compliance and Product Status: Active product status and current compliance certifications (RoHS3, REACH) are preferred for long-term availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The STTH810D from STMicroelectronics is identified as a suitable substitute for the obsolete 10ETS08. The following factors support this substitution:

Voltage Margin: The STTH810D provides 1000 V reverse voltage rating, exceeding the 10ETS08 specification of 800 V. This 200 V margin enhances design robustness without introducing circuit incompatibility.

Current Capability: The STTH810D is rated for 8 A average rectified current, which is 2 A lower than the 10ETS08 specification of 10 A. Circuit designs operating at or below 8 A can use this substitute without derating. Designs requiring the full 10 A capacity require alternative solutions.

Package Compatibility: Both devices use identical TO-220-2 through-hole packaging, ensuring direct mechanical and thermal interface compatibility with existing PCB layouts.

Recovery Characteristics: The STTH810D features fast recovery (≤500ns) compared to the standard recovery (>500ns) of the 10ETS08. Fast recovery reduces switching losses and is compatible with standard rectification applications.

Compliance Status: The STTH810D holds active product status and ROHS3 compliance certification, supporting long-term procurement availability and regulatory alignment with current manufacturing standards.

Temperature Rating: The STTH810D maximum junction temperature of 175°C exceeds the 10ETS08 specification of 150°C, providing additional thermal margin.

Frequently Asked Questions (FAQ)

Q: Can the STTH810D directly replace the 10ETS08 in all applications?

A: Direct replacement is possible only in applications where the average rectified current does not exceed 8 A. The STTH810D current rating of 8 A is 2 A lower than the 10ETS08 specification of 10 A. Applications requiring the full 10 A capacity require alternative substitute parts.

Q: What is the significance of the voltage rating difference between 800 V and 1000 V?

A: The STTH810D 1000 V rating exceeds the 10ETS08 800 V specification by 200 V. This higher rating provides design margin and does not compromise circuit function. The substitute operates safely in circuits designed for 800 V operation.

Q: How does the forward voltage difference affect circuit performance?

A: The STTH810D exhibits 2 V forward voltage at 8 A, compared to 1.1 V for the 10ETS08 at 10 A. At equivalent current levels, the STTH810D forward voltage is higher, resulting in increased power dissipation and heat generation. Thermal management design must account for this difference.

Q: Are the TO-220-2 packages identical between the two parts?

A: Yes. Both the 10ETS08 and STTH810D use TO-220-2 through-hole packaging. Mechanical and thermal interface compatibility with existing PCB designs is maintained. No layout modifications are required.

Q: What is the advantage of fast recovery in the STTH810D?

A: The STTH810D fast recovery characteristic (≤500ns, 85 ns trr) reduces reverse recovery losses compared to the 10ETS08 standard recovery (>500ns). This results in lower switching losses and improved efficiency in rectification circuits. Fast recovery is compatible with standard rectification applications.

Q: Does the STTH810D comply with current regulatory standards?

A: Yes. The STTH810D holds ROHS3 compliance certification and active product status. The 10ETS08 is RoHS non-compliant and obsolete. The STTH810D supports long-term procurement and regulatory alignment with current manufacturing standards.

Q: What is the reverse leakage current difference, and does it matter?

A: The STTH810D exhibits 5 µA reverse leakage at 1000 V, compared to 50 µA for the 10ETS08 at 800 V. Lower reverse leakage reduces standby power consumption and indicates superior device quality. This difference is beneficial for low-power standby applications.

Q: Can I use the STTH810D in a circuit designed for 10 A operation?

A: No. The STTH810D is rated for 8 A average rectified current. Using it in a circuit requiring 10 A operation exceeds the device specification and risks thermal stress and premature failure. Alternative substitute parts with 10 A or higher ratings must be identified for such applications.
