Parameter Comparison

Engineering Selection Recommendations

The DST3080C from Littelfuse Inc. is a direct electrical and mechanical equivalent to the VT3080C-M3/4W. Both components satisfy identical specifications across all critical parameters: 80 V reverse voltage rating, 15 A average rectified current, 820 mV forward voltage drop at 15 A, and fast recovery Schottky technology with ≤ 500ns switching speed.

Both parts are qualified to ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for automotive and industrial applications. The DST3080C maintains the same operating temperature range (-55°C to 150°C junction temperature) and identical moisture sensitivity classification (MSL 1 - Unlimited).

The TO-220-3 package footprint is mechanically identical between both manufacturers, enabling direct PCB layout compatibility. Selection between VT3080C-M3/4W and DST3080C may be based on supply availability, lead time, or procurement preference, as both components deliver equivalent performance in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the DST3080C replace the VT3080C-M3/4W in existing designs?

A: Yes. The DST3080C is electrically and mechanically equivalent. All critical parameters—reverse voltage (80 V), forward current (15 A), forward voltage drop (820 mV @ 15 A), switching speed (≤ 500ns), and operating temperature range (-55°C to 150°C)—are identical. The TO-220-3 package footprint is the same, enabling direct substitution without PCB redesign.

Q: Are there package differences between VT3080C-M3/4W and DST3080C?

A: Both components use the TO-220-3 through-hole package. The Supplier Device Package designation differs (TO-220-3 for Vishay versus TO-220AB for Littelfuse), but these refer to the same physical package form factor and pin configuration. No mechanical adaptation is required.

Q: Do both parts meet automotive qualification standards?

A: The VT3080C-M3/4W carries AEC-Q101 automotive qualification. Both parts are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for automotive and industrial applications. Verify specific AEC-Q101 status with Littelfuse for the DST3080C if automotive qualification is a mandatory design requirement.

Q: What is the reverse leakage current specification for both parts?

A: Both the VT3080C-M3/4W and DST3080C specify 700 µA maximum reverse leakage current at 80 V. This parameter is identical across both components.

Q: Are there any differences in forward voltage characteristics?

A: No. Both parts specify 820 mV maximum forward voltage drop at 15 A forward current. Forward voltage characteristics are identical.

Q: What is the moisture sensitivity level for these diodes?

A: Both components are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard component storage practices apply.
