TSF20U60C Equivalent & Substitute Parts

Part Overview

The TSF20U60C is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as a 1 Pair Common Cathode arrangement with a 60 V DC 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 configuration for through-hole mounting applications. This component is classified as Active product status and is RoHS3 compliant.

Equivalent and substitute parts are identified based on matching or compatible electrical and mechanical parameters within the Schottky diode rectifier category. Substitution becomes necessary when the primary part is unavailable, when inventory constraints exist, or when design flexibility permits selection from qualified alternatives that maintain functional compatibility within specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSF20U60C is determined by the following critical parameters:

Primary Matching Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 60 V minimum
• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack, Isolated Tab or compatible variant
• Supplier Device Package: ITO-220AB or equivalent

Secondary Compatibility Criteria:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 10 A
• Voltage - Forward (Vf) (Max) @ If: Within acceptable operating range
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: Minimum -55°C, maximum 150°C
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories:

Category A - Direct Equivalents: Parts matching all primary criteria with Io ≥ 10 A and Vr = 60 V.

Category B - Compatible Alternatives: Parts with modified electrical parameters (higher voltage rating or different current rating) that maintain functional compatibility within the application envelope, provided the package and configuration remain compatible.

Engineering Selection Recommendations

VFT3060C-E3/4W (Vishay General Semiconductor - Diodes Division)

The VFT3060C-E3/4W is a direct equivalent substitute for the TSF20U60C. Both devices share identical voltage ratings (60 V), matching diode configuration (1 Pair Common Cathode), identical package type (TO-220-3 Full Pack, Isolated Tab), and compatible supplier device package (ITO-220AB). The VFT3060C-E3/4W provides higher current capacity (15 A versus 10 A per diode), which extends operational margin in current-limited applications. Both parts are RoHS3 compliant, MSL 1, and REACH Unaffected. The VFT3060C-E3/4W is part of the TMBS® series and maintains identical operating temperature range (-55°C ~ 150°C). This part is suitable for direct substitution without circuit modification.

STF2060C (SMC Diode Solutions)

The STF2060C is a compatible substitute with matching voltage rating (60 V), diode configuration (1 Pair Common Cathode), package type (TO-220-3 Full Pack, Isolated Tab), and supplier device package (ITO-220AB). Forward voltage specification (650 mV @ 10 A) is within acceptable range relative to the TSF20U60C (540 mV @ 10 A). Both parts are RoHS3 compliant and MSL 1. The STF2060C is suitable for direct substitution. Note: REACH Status is Affected for this part.

MBRF1560CT-E3/45 (Vishay General Semiconductor - Diodes Division)

The MBRF1560CT-E3/45 is a compatible substitute with matching voltage rating (60 V), diode configuration (1 Pair Common Cathode), package type (TO-220-3 Full Pack, Isolated Tab), and supplier device package (ITO-220AB). Current rating is reduced to 7.5 A per diode compared to the TSF20U60C (10 A). This part is suitable for substitution in applications where the required current does not exceed 7.5 A per diode. Operating temperature range extends to -65°C minimum, providing enhanced low-temperature performance. Both parts are RoHS3 compliant, MSL 1, and REACH Unaffected.

STF20100 (SMC Diode Solutions)

The STF20100 is a compatible alternative with elevated voltage rating (100 V versus 60 V). Package configuration differs: TO-220-2 Full Pack, Isolated Tab (ITO-220AC) versus TO-220-3 Full Pack, Isolated Tab (ITO-220AB). This part is suitable for substitution only in applications where the circuit topology accommodates the different pin configuration and where the higher voltage rating does not introduce design constraints. Note: REACH Status is Affected for this part.

Frequently Asked Questions (FAQ)

Q: Can the VFT3060C-E3/4W replace the TSF20U60C in all applications?

A: Yes. The VFT3060C-E3/4W is a direct equivalent with identical voltage rating (60 V), diode configuration (1 Pair Common Cathode), and package type (TO-220-3 Full Pack, Isolated Tab). The higher current rating (15 A versus 10 A per diode) provides additional operational margin and does not introduce compatibility issues. No circuit modification is required.

Q: What is the difference between the TO-220-3 and TO-220-2 package variants?

A: The TO-220-3 Full Pack, Isolated Tab (ITO-220AB) contains three leads and is used for diode array configurations with common cathode connection. The TO-220-2 Full Pack, Isolated Tab (ITO-220AC) contains two leads and is used for single diode configurations. The STF20100 uses the TO-220-2 variant and is not a direct pin-compatible substitute for the TSF20U60C.

Q: Is the MBRF1560CT-E3/45 suitable for applications requiring 10 A per diode?

A: The MBRF1560CT-E3/45 is rated for 7.5 A per diode, which is below the TSF20U60C specification of 10 A per diode. This part is suitable only for applications where the required current does not exceed 7.5 A per diode. Operating at or above the rated current may result in thermal stress and reduced component reliability.

Q: What is the significance of REACH Status in part selection?

A: REACH Status indicates regulatory compliance with the European Union's Registration, Evaluation, Authorization and Restriction of Chemicals regulation. Parts marked as REACH Unaffected (TSF20U60C, VFT3060C-E3/4W, MBRF1560CT-E3/45) are not subject to REACH restrictions. Parts marked as REACH Affected (STF2060C, STF20100) may be subject to additional regulatory requirements depending on application and end-use jurisdiction. Selection should account for regulatory requirements applicable to the end product.

Q: Can the STF20100 be used as a substitute for the TSF20U60C?

A: The STF20100 has a higher voltage rating (100 V versus 60 V) and uses a different package configuration (TO-220-2 versus TO-220-3). Substitution is possible only if the circuit topology accommodates the different pin configuration and if the elevated voltage rating does not introduce design constraints such as increased leakage current or unintended circuit behavior. Direct pin-for-pin substitution is not possible.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity limitations. The part does not require special moisture control during storage, handling, or assembly. Standard storage and handling procedures are sufficient.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed (TSF20U60C, VFT3060C-E3/4W, MBRF1560CT-E3/45, STF2060C, STF20100) are RoHS3 compliant, indicating compliance with the Restriction of Hazardous Substances Directive 3 requirements for lead-free and restricted substance content.

Q: What is the primary difference in forward voltage between the TSF20U60C and its substitutes?

A: The TSF20U60C specifies 540 mV forward voltage at 10 A. The VFT3060C-E3/4W specifies 700 mV at 15 A, the MBRF1560CT-E3/45 specifies 750 mV at 7.5 A, and the STF2060C specifies 650 mV at 10 A. Forward voltage differences reflect manufacturing process variations and current rating differences. These variations are within acceptable ranges for Schottky diode rectifiers and do not typically require circuit redesign.
