Key Parameters

Substitute Part Grouping Explanation

Substitution of the VT2080C-E3/4W is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 80 V
• Current - Average Rectified (Io) (per Diode): 10 A
• Voltage - Forward (Vf) (Max) @ If: 810 mV @ 10 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 600 µA @ 80 V
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: TO-220-3

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The DST2080C from Littelfuse Inc. meets all specified electrical, mechanical, and compliance requirements and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the VT2080C-E3/4W and DST2080C are Active product status components with full ROHS3 compliance and REACH Unaffected status. The DST2080C from Littelfuse Inc. is electrically and mechanically equivalent to the VT2080C-E3/4W from Vishay General Semiconductor - Diodes Division. All critical electrical parameters, including reverse voltage rating, forward current capacity, forward voltage drop, switching speed, and reverse leakage current, are identical. Both devices operate across the same temperature range and are packaged in TO-220-3 through-hole configurations suitable for PCB mounting.

The Supplier Device Package designation differs (TO-220-3 versus TO-220AB), but both designations refer to the same physical TO-220-3 package form factor and pin configuration. This difference reflects manufacturer-specific package nomenclature and does not affect functional or mechanical compatibility.

Selection between these parts should be based on availability, lead time, and supply chain requirements. Both parts satisfy identical design specifications and regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the DST2080C replace the VT2080C-E3/4W in existing designs?

A: Yes. The DST2080C is electrically and mechanically equivalent. All electrical parameters, including voltage ratings, current capacity, forward voltage drop, and switching characteristics, are identical. Both devices use the same TO-220-3 through-hole package with identical pin configuration.

Q: Are there any differences in the package designation between these parts?

A: The VT2080C-E3/4W uses the designation TO-220-3, while the DST2080C uses TO-220AB. Both designations refer to the same physical TO-220-3 package form factor. This difference reflects manufacturer-specific nomenclature and does not affect mechanical compatibility or PCB layout.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the VT2080C-E3/4W and DST2080C are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Both are Active product status components.

Q: What are the critical electrical parameters that define substitution?

A: Substitution is based on matching: Diode Configuration (1 Pair Common Cathode), Technology (Schottky), Voltage - DC Reverse (80 V), Current - Average Rectified (10 A per diode), Voltage - Forward (810 mV @ 10 A), Speed (Fast Recovery ≤ 500ns), Current - Reverse Leakage (600 µA @ 80 V), and Operating Temperature Range (-55°C to 150°C).

Q: Can these parts be used in high-temperature applications?

A: Both parts are rated for junction operating temperatures from -55°C to 150°C. Applications requiring operation at the upper temperature limit should verify thermal management and heat dissipation design to maintain junction temperature within specification.

Q: What is the difference between the base product numbers VT2080 and DST2080?

A: The base product numbers identify the manufacturer's product line. VT2080 is the Vishay base designation, while DST2080 is the Littelfuse base designation. The suffix and packaging designations (VT2080C-E3/4W and DST2080C) specify the exact configuration and packaging. Despite different base numbers, the electrical and mechanical specifications are equivalent.
