Engineering Selection Recommendations

Direct Replacement (Preferred):

MBRF2060CT-E3/45 and MBRF2060CTHE3/45 are direct electrical and mechanical equivalents to the TSF20L60C. Both parts maintain the 60 V reverse voltage rating, 10 A average rectified current per diode, and TO-220-3 ITO-220AB package configuration. Both are manufactured by Vishay General Semiconductor and carry Active product status with ROHS3 compliance. The MBRF2060CTHE3/45 variant includes AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade reliability.

VFT2060C-E3/4W is an alternative direct equivalent manufactured by Vishay General Semiconductor. This part is part of the TMBS® series, maintains identical voltage and current ratings, and operates within the same temperature range as the TSF20L60C. It carries Active product status and ROHS3 compliance.

STF2060C, manufactured by SMC Diode Solutions, provides electrical compatibility with matching 60 V voltage rating and TO-220-3 ITO-220AB package. This part is Active and ROHS3 compliant, though current rating specification is not provided in available data.

Compatible Substitutes (Current Derating Required):

MBRF1560CT-E3/45 and MBRF1560CTHE3/45 are compatible substitutes with reduced current rating (7.5 A versus 10 A). These parts maintain the 60 V voltage rating and TO-220-3 ITO-220AB package. Applications requiring the full 10 A rating must not use these parts. The MBRF1560CTHE3/45 variant includes AEC-Q101 automotive qualification.

Compatible Substitutes (Current Upgrading Possible):

MBRF2560CT-E3/45 and MBRF2560CT/45 are compatible substitutes with increased current rating (15 A versus 10 A). Both maintain the 60 V voltage rating and TO-220-3 ITO-220AB package. These parts are suitable for applications where higher current capacity is beneficial. The MBRF2560CT-E3/45 carries ROHS3 compliance and Active status. The MBRF2560CT/45 is Active but RoHS non-compliant.

Not Recommended:

STF20100 is not recommended as a substitute. Although it maintains through-hole mounting, it uses a different package configuration (TO-220-2 ITO-220AC instead of TO-220-3 ITO-220AB) and operates at 100 V reverse voltage, which exceeds the TSF20L60C specification.

VFT1060C-E3/4W is not recommended as a direct substitute due to reduced current rating (5 A versus 10 A). This part is suitable only for applications with lower current requirements.

Frequently Asked Questions (FAQ)

Q: Can MBRF2060CT-E3/45 be used as a direct replacement for TSF20L60C?

A: Yes. MBRF2060CT-E3/45 is a direct electrical and mechanical equivalent. Both parts maintain 60 V reverse voltage rating, 10 A average rectified current per diode, and TO-220-3 ITO-220AB package configuration. The MBRF2060CT-E3/45 is manufactured by Vishay General Semiconductor and carries Active product status with ROHS3 compliance.

Q: What is the difference between MBRF2060CT-E3/45 and MBRF2060CTHE3/45?

A: Both parts are electrically and mechanically identical with matching 60 V voltage rating, 10 A current rating, and TO-220-3 ITO-220AB package. The primary difference is that MBRF2060CTHE3/45 includes AEC-Q101 automotive qualification, making it suitable for automotive applications requiring automotive-grade reliability certification.

Q: Can MBRF1560CT-E3/45 replace TSF20L60C in all applications?

A: No. MBRF1560CT-E3/45 has a reduced current rating of 7.5 A compared to the TSF20L60C's 10 A rating. This part is suitable only for applications where the required current does not exceed 7.5 A per diode. Applications requiring the full 10 A rating must use parts with matching or higher current specifications.

Q: Is VFT2060C-E3/4W compatible with TSF20L60C?

A: Yes. VFT2060C-E3/4W is a direct electrical and mechanical equivalent. Both parts maintain 60 V reverse voltage rating, 10 A average rectified current per diode, and TO-220-3 ITO-220AB package configuration. VFT2060C-E3/4W is part of the TMBS® series and carries Active product status with ROHS3 compliance.

Q: Why is STF20100 not recommended as a substitute?

A: STF20100 uses a different package configuration (TO-220-2 ITO-220AC instead of TO-220-3 ITO-220AB) and operates at 100 V reverse voltage, which exceeds the TSF20L60C specification of 60 V. The different package configuration prevents direct mechanical compatibility with existing PCB layouts designed for TO-220-3 devices.

Q: Can MBRF2560CT-E3/45 be used instead of TSF20L60C?

A: Yes. MBRF2560CT-E3/45 is a compatible substitute with increased current rating (15 A versus 10 A). Both parts maintain 60 V reverse voltage rating and TO-220-3 ITO-220AB package configuration. The higher current rating provides additional design margin and is suitable for applications where increased current capacity is beneficial or required.

Q: What compliance certifications should I verify when selecting a substitute?

A: All recommended direct equivalents and compatible substitutes carry ROHS3 compliance. For automotive applications, verify AEC-Q101 qualification. The MBRF2060CTHE3/45 and MBRF1560CTHE3/45 variants include AEC-Q101 automotive qualification. Confirm that the selected part meets your application's specific compliance requirements before implementation.

Q: Are there any forward voltage differences between TSF20L60C and its substitutes?

A: Yes. The TSF20L60C specifies 660 mV maximum forward voltage at 10 A. Direct equivalents show variations: MBRF2060CT-E3/45 specifies 800 mV at 10 A, while VFT2060C-E3/4W specifies 650 mV at 10 A. These differences are within acceptable ranges for Schottky diode applications but should be verified against your circuit's specific requirements, particularly in low-voltage or high-efficiency designs.

Q: What is the operating temperature range difference between TSF20L60C and substitute parts?

A: The TSF20L60C operates from -55°C to 150°C. Most Vishay substitutes (MBRF series and VFT series) operate from -65°C to 150°C, providing extended low-temperature capability. SMC Diode Solutions parts (STF series) operate from -55°C to 150°C, matching the TSF20L60C range. Verify that the selected substitute meets your application's temperature requirements.
