8ETL06FP Equivalent & Substitute Parts

Part Overview

The 8ETL06FP is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 600 V DC reverse voltage and 8 A average rectified current in a TO-220-2 Full Pack through-hole package. This component is classified as obsolete, indicating that direct procurement may face supply constraints. Identifying equivalent and substitute parts ensures design continuity and maintains access to functionally compatible alternatives that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the 8ETL06FP is determined by the following critical parameters:

Mandatory Matching Criteria:

Voltage - DC Reverse (Vr) (Max): 600 V
Mounting Type: Through Hole
Package / Case: TO-220-2 Full Pack or compatible TO-220 variants
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Current Rating Flexibility: Substitute parts may have equal or higher average rectified current (Io) ratings, provided all other electrical and mechanical parameters remain compatible. The 8 A rating of the 8ETL06FP establishes a minimum threshold; parts rated at 9 A, 10 A, 12 A, 15 A, or 20 A are electrically compatible for applications requiring 8 A or less.

Forward Voltage Consideration: Forward voltage (Vf) varies among substitute parts. Parts with lower Vf values (such as RFNL series at 1.3 V @ rated current) offer improved efficiency compared to the original 1.05 V @ 8 A specification. Parts with higher Vf values (such as FFPF10UA60ST at 2.3 V @ 10 A) remain functionally compatible but may increase power dissipation in the application circuit.

Reverse Recovery Time (trr): Substitute parts exhibit trr values ranging from 45 ns to 250 ns. Faster recovery times (lower trr) reduce switching losses and electromagnetic interference in high-frequency applications. All listed substitutes meet the fast recovery classification.

Reverse Leakage Current: The original part specifies 5 µA @ 600 V. Substitute parts specify 10 µA to 50 µA @ 600 V. This parameter affects standby power consumption and thermal performance in low-current applications.

Temperature Rating: The original part operates from -65°C to 175°C. Substitute parts operate within -65°C to 175°C or -65°C to 150°C ranges. Parts with 150°C maximum junction temperature are suitable for applications not exceeding this limit.

Compliance Status: The original 8ETL06FP is RoHS non-compliant. Active substitute parts are ROHS3 compliant, supporting modern procurement and environmental requirements.

Engineering Selection Recommendations

For Direct Replacement (Same Current Rating):

The RFV8TJ6SGC9 (Rohm Semiconductor) provides the closest electrical match to the 8ETL06FP, with identical 8 A average rectified current and 600 V reverse voltage rating. This part is active in production status and ROHS3 compliant. The primary trade-off is forward voltage: RFV8TJ6SGC9 exhibits 2.8 V @ 8 A compared to the original 1.05 V @ 8 A, resulting in increased power dissipation. Reverse recovery time is significantly faster (45 ns versus 250 ns), reducing switching losses in high-frequency applications. Maximum junction temperature is 150°C, compared to 175°C for the original part.

For Higher Current Capacity with Active Status:

The MURF1560G (onsemi) is rated for 15 A at 600 V and maintains the full -65°C to 175°C operating temperature range of the original part. This part is active in production and ROHS3 compliant. Forward voltage is 1.5 V @ 15 A, representing a moderate increase from the original specification. Reverse recovery time is 60 ns, providing improved switching performance. This part is suitable for applications requiring current headroom or future design scaling.

For Compliance-Driven Substitution:

All listed substitute parts except FFPF10UA60ST are active in production status. FFPF10UA60ST, while ROHS3 compliant, is classified as obsolete and should not be selected for new designs requiring long-term supply assurance. The Rohm Semiconductor RFNL and RFV series parts offer the broadest current range (5 A to 20 A) with consistent 600 V ratings and active production status, supporting flexible design requirements and supply continuity.

Temperature Derating Consideration:

Applications operating near the upper temperature limit should account for the 150°C maximum junction temperature of most substitute parts, compared to 175°C for the original 8ETL06FP. The MURF1560G maintains the 175°C rating and is preferred for high-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher current rating than the original 8ETL06FP?

A: Yes. A substitute part with equal or higher average rectified current (Io) rating is electrically compatible for applications requiring 8 A or less. For example, the RFNL10TJ6SGC9 (10 A) or MURF1560G (15 A) can replace the 8ETL06FP (8 A) without exceeding the original current requirement. The application circuit will not draw more current than designed; the higher rating provides margin and thermal headroom.

Q: What is the impact of different forward voltage (Vf) values on my circuit?

A: Forward voltage directly affects power dissipation in the diode. The original 8ETL06FP specifies 1.05 V @ 8 A. Substitute parts range from 1.3 V to 2.8 V at their rated currents. Higher Vf values increase heat generation and may require thermal management adjustments. Lower Vf values improve efficiency. Verify that your circuit design accommodates the voltage drop of the selected substitute part, particularly in low-voltage applications or high-current paths.

Q: Does reverse recovery time (trr) affect my application?

A: Reverse recovery time impacts switching speed and electromagnetic interference (EMI) characteristics. The original 8ETL06FP has trr of 250 ns. Substitute parts range from 45 ns to 180 ns, all meeting the fast recovery classification (≤ 500 ns). Faster recovery times reduce switching losses and EMI in high-frequency rectification circuits. For low-frequency applications (50 Hz to 60 Hz line rectification), trr differences have minimal practical impact.

Q: Are all substitute parts RoHS compliant?

A: The original 8ETL06FP is RoHS non-compliant. All listed substitute parts are ROHS3 compliant, meeting current environmental and procurement standards. If your supply chain or end-product requirements mandate RoHS compliance, any of the listed substitutes satisfy this requirement.

Q: What is the difference between TO-220-2 Full Pack and TO-220ACFP packaging?

A: Both are through-hole TO-220 variants with two leads (anode and cathode). TO-220-2 Full Pack and TO-220ACFP are mechanically compatible for PCB mounting and heatsink attachment. The primary difference is thermal tab isolation: some variants feature an isolated tab for improved thermal performance in specific circuit topologies. Verify heatsink mounting compatibility with your mechanical design.

Q: Can I use FFPF10UA60ST as a substitute?

A: FFPF10UA60ST meets the electrical specifications (600 V, 10 A, fast recovery) and is ROHS3 compliant. However, this part is classified as obsolete, indicating limited future availability. For new designs or long-term production, select an active-status substitute such as MURF1560G, RFNL10TJ6SGC9, or RFV8TJ6SGC9 to ensure supply continuity.

Q: What is the maximum junction temperature limitation for substitute parts?

A: The original 8ETL06FP operates to 175°C junction temperature. Most Rohm Semiconductor substitutes (RFNL and RFV series) and WeEn BYV29X-600,127 are rated to 150°C maximum. The onsemi MURF1560G maintains 175°C. For applications operating near 175°C, select MURF1560G or verify that your thermal design maintains junction temperature below 150°C when using other substitutes.

Q: Which substitute part offers the best efficiency?

A: The RFNL series (RFNL5TJ6SGC9, RFNL10TJ6SGC9, RFNL15TJ6SGC9, RFNL20TJ6SGC9) offers forward voltage of 1.3 V across all current ratings, representing the lowest Vf among active substitutes. This reduces power dissipation and improves overall circuit efficiency compared to the original 1.05 V @ 8 A specification or higher-Vf alternatives. Select the RFNL part matching your required current rating.
