DSTF2050C Equivalent & Substitute Parts

Part Overview

The DSTF2050C is a Schottky diode array manufactured by Littelfuse Inc., configured as a 1 Pair Common Cathode arrangement with a 50 V reverse voltage rating and 10 A average rectified current per diode. The device is packaged in a TO-220-3 Full Pack with isolated tab for through-hole mounting applications. This component is classified as Active product status and is ROHS3 compliant.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement in circuit applications. Substitution becomes necessary due to inventory availability, supply chain considerations, or design flexibility requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DSTF2050C are identified based on the following critical parameters that determine functional compatibility:

Configuration Match: Diode array must be 1 Pair Common Cathode topology to maintain circuit interface compatibility.

Technology Match: Schottky technology is required to preserve switching characteristics and forward voltage behavior.

Voltage Rating: Reverse voltage rating must be equal to or greater than 50 V to ensure safe operation under maximum applied voltage conditions.

Current Rating: Average rectified current per diode must be equal to or greater than 10 A to handle circuit load requirements.

Speed Characteristic: Fast Recovery classification (≤ 500ns, > 200mA) must be maintained for switching performance consistency.

Package Compatibility: TO-220-3 Full Pack with isolated tab and through-hole mounting type ensures mechanical and thermal interface compatibility.

Compliance: ROHS3 compliance and MSL 1 rating are required for regulatory and manufacturing process compatibility.

The MBRF2545CT-E3/45 is identified as a manufacturer-recommended substitute based on these parameters, with specific electrical differences noted in the comparison table below.

Engineering Selection Recommendations

DSTF2050C Selection: This part is the primary choice when the 50 V reverse voltage rating is required for the application. The component is Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating, suitable for standard manufacturing and storage conditions. Current inventory of 953 pieces supports immediate availability.

MBRF2545CT-E3/45 Selection: This substitute is applicable in circuits where the 45 V reverse voltage rating is sufficient for the design margin. The part offers higher current capacity (12.5 A versus 10 A per diode) and extended lower operating temperature range (-65°C versus -55°C). The substitute is Active product status with equivalent ROHS3 compliance and MSL 1 rating. Current inventory of 1427 pieces provides alternative supply availability.

Compliance Considerations: Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical ECCN and HTSUS classifications, ensuring regulatory equivalence for procurement and export purposes.

Frequently Asked Questions (FAQ)

Q: Can MBRF2545CT-E3/45 replace DSTF2050C in all applications?

A: The MBRF2545CT-E3/45 is suitable for replacement when the circuit design operates at reverse voltages of 45 V or below. If the application requires the full 50 V reverse voltage rating of the DSTF2050C, the substitute is not appropriate. Both parts share identical diode configuration, Schottky technology, fast recovery speed, and TO-220-3 package format.

Q: What are the key electrical differences between these parts?

A: The DSTF2050C provides 50 V reverse voltage rating with 10 A current per diode. The MBRF2545CT-E3/45 provides 45 V reverse voltage rating with 12.5 A current per diode. Forward voltage characteristics differ at different measurement points (550 mV @ 10 A versus 820 mV @ 30 A). Reverse leakage current differs significantly (1.5 mA @ 50 V versus 200 µA @ 45 V).

Q: Are the packages mechanically identical?

A: Both parts use TO-220-3 Full Pack with isolated tab configuration for through-hole mounting. The mechanical footprint and thermal interface are identical, allowing direct PCB mounting compatibility.

Q: What is the temperature operating range difference?

A: The DSTF2050C operates from -55°C to 150°C junction temperature. The MBRF2545CT-E3/45 extends the lower temperature limit to -65°C, providing 10°C additional cold-temperature capability. Both parts share the same 150°C upper limit.

Q: Are both parts RoHS compliant?

A: Both the DSTF2050C and MBRF2545CT-E3/45 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both are REACH Unaffected and share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Which part should be selected for new designs?

A: Selection depends on circuit voltage requirements. For designs requiring 50 V reverse voltage margin, specify DSTF2050C. For designs operating at 45 V or below with higher current capacity needs, MBRF2545CT-E3/45 is applicable. Both parts are Active product status with equivalent compliance and reliability ratings.
