Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8EWF06STR is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 8 A
• Voltage - Forward (Vf) (Max) @ If: 1.2 V @ 8 A
• Speed Classification: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Current - Reverse Leakage @ Vr: 100 µA @ 600 V
• Operating Temperature - Junction: -40°C ~ 150°C

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Supplier Device Package: TO-252AA (DPAK)
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed maintain these core parameters. Substitute parts are available in active product status with Tape & Reel (TR) packaging, offering improved availability compared to the obsolete 8EWF06STR.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts (VS-8EWF06SLHM3, VS-8EWF06STR-M3, VS-8EWF06STRL-M3, and VS-8EWF06STRR-M3) are direct electrical and mechanical equivalents to the 8EWF06STR. The primary distinctions are:

Product Status: All substitute parts are classified as active, ensuring long-term availability and supply chain continuity compared to the obsolete 8EWF06STR.

Compliance: All substitute parts are ROHS3 compliant, whereas the 8EWF06STR is RoHS non-compliant. This compliance improvement is significant for applications subject to RoHS regulations.

Reverse Recovery Time: Substitute parts exhibit 55 ns reverse recovery time compared to 140 ns for the 8EWF06STR. This improved performance characteristic does not affect direct substitution compatibility.

Packaging: All substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The 8EWF06STR was supplied in bulk packaging.

Automotive Grade: VS-8EWF06SLHM3 carries AEC-Q101 automotive qualification, making it suitable for automotive applications requiring this certification.

Inventory Availability: VS-8EWF06SLHM3 offers the highest inventory level at 30,300 pieces, followed by VS-8EWF06STR-M3 at 15,300 pieces.

Frequently Asked Questions (FAQ)

Q: Can the substitute parts be used as direct replacements for the 8EWF06STR in existing designs?

A: Yes. All substitute parts maintain identical electrical ratings (600 V, 8 A, 1.2 V forward voltage) and mechanical specifications (TO-252AA DPAK package). The parts are pin-compatible and functionally equivalent for circuit operation.

Q: What is the significance of the improved reverse recovery time in substitute parts?

A: The substitute parts feature 55 ns reverse recovery time compared to 140 ns in the 8EWF06STR. This represents improved switching performance and reduced switching losses. This enhancement does not prevent direct substitution and may improve overall circuit efficiency.

Q: Why is RoHS3 compliance important for the substitute parts?

A: RoHS3 compliance indicates conformance to current environmental and hazardous substance restrictions. The 8EWF06STR is RoHS non-compliant, which may restrict its use in applications or markets with RoHS requirements. All substitute parts are ROHS3 compliant, eliminating this restriction.

Q: Is the automotive-grade qualification of VS-8EWF06SLHM3 necessary for all applications?

A: AEC-Q101 qualification is required only for automotive applications. For non-automotive applications, all four substitute parts are functionally equivalent. Selection should be based on application requirements and supply chain preferences.

Q: How does the Tape & Reel packaging of substitute parts differ from the bulk packaging of the 8EWF06STR?

A: Tape & Reel packaging is the standard format for automated surface mount assembly. It provides better handling, reduced component damage during manufacturing, and improved traceability. Bulk packaging is less common in modern manufacturing environments.

Q: Are there any electrical performance differences between the four substitute parts?

A: No. All four substitute parts (VS-8EWF06SLHM3, VS-8EWF06STR-M3, VS-8EWF06STRL-M3, and VS-8EWF06STRR-M3) maintain identical electrical specifications. Differences are limited to product status, compliance certifications, and packaging format.

Q: Which substitute part should be selected for new designs?

A: For new designs, selection should prioritize active product status and compliance requirements. VS-8EWF06SLHM3 is recommended for automotive applications requiring AEC-Q101 qualification. VS-8EWF06STR-M3 is recommended for general industrial applications due to high inventory availability.
