TSF20H100C-S Equivalent & Substitute Parts

Part Overview

The TSF20H100C-S is an active Schottky diode rectifier manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 10 A average rectified current in a through-hole TO-220-3 package with isolated tab configuration. This component is designed for fast recovery applications with switching speeds ≤ 500 ns and operates across a junction temperature range of -55°C to 150°C. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when application requirements necessitate alternative electrical or thermal characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSF20H100C-S is determined by the following critical parameters: reverse voltage rating (Vr), average rectified current capacity (Io), forward voltage drop (Vf), reverse leakage current, switching speed, mounting type, and package configuration. All substitute parts must maintain Schottky diode technology and through-hole mounting to ensure mechanical and electrical compatibility within the application circuit.

The identified substitute parts are grouped as follows:

Group 1: Voltage-Reduced Substitute (STF1060) This part operates at a reduced reverse voltage rating of 60 V, making it suitable only for applications where the circuit operates below this voltage threshold. It is not a direct functional equivalent for 100 V applications.

Group 2: Current-Enhanced Equivalent (VF30100S-E3/4W) This part maintains the 100 V reverse voltage rating and TO-220-3 package configuration while providing increased current capacity of 30 A, making it suitable for applications requiring higher current handling or thermal margin.

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Equivalence (100 V, 10 A Applications): The VF30100S-E3/4W from Vishay General Semiconductor maintains the 100 V reverse voltage rating and TO-220-3 package configuration required for direct substitution. This part provides enhanced current capacity of 30 A, offering increased thermal margin and design flexibility. Both the main part and this substitute are ROHS3 compliant and REACH unaffected, ensuring regulatory compliance. The operating temperature range of -40°C to 150°C is compatible with the -55°C to 150°C specification of the main part for applications operating above -40°C.

For Reduced Voltage Applications (≤ 60 V): The STF1060 from SMC Diode Solutions is suitable only for circuits operating at or below 60 V reverse voltage. This part features a TO-220-2 package configuration, which differs from the TO-220-3 of the main part. The STF1060 is ROHS3 compliant but REACH affected, requiring verification of regulatory requirements for the end application. This substitute is not appropriate for 100 V applications.

Compliance and Certification: All three parts maintain ROHS3 compliance and operate within the specified temperature ranges for industrial and commercial applications. The main part and VF30100S-E3/4W are both REACH unaffected, while STF1060 is REACH affected. Selection should account for end-use regulatory requirements and supply chain constraints.

Frequently Asked Questions (FAQ)

Q: Can the STF1060 be used as a direct replacement for the TSF20H100C-S? A: No. The STF1060 has a maximum reverse voltage rating of 60 V, compared to 100 V for the TSF20H100C-S. It is suitable only for applications operating at 60 V or below. Additionally, the STF1060 uses a TO-220-2 package, while the main part uses TO-220-3, resulting in different pin configurations.

Q: Is the VF30100S-E3/4W a direct equivalent to the TSF20H100C-S? A: The VF30100S-E3/4W maintains the same 100 V reverse voltage rating and TO-220-3 package configuration as the TSF20H100C-S. It provides higher current capacity (30 A versus 10 A), making it suitable for applications requiring increased current handling or thermal margin. The minimum operating temperature is -40°C instead of -55°C; applications requiring operation below -40°C must use the main part.

Q: What are the key differences in forward voltage drop between these parts? A: The TSF20H100C-S exhibits 790 mV forward voltage at 10 A, the STF1060 exhibits 650 mV at 10 A, and the VF30100S-E3/4W exhibits 910 mV at 30 A. Forward voltage characteristics vary with current rating and manufacturing process. Circuit designs sensitive to voltage drop should account for these differences.

Q: Are all three parts RoHS compliant? A: Yes, all three parts are ROHS3 compliant. However, the STF1060 is REACH affected, while the TSF20H100C-S and VF30100S-E3/4W are REACH unaffected. Applications subject to REACH regulations should verify compliance requirements before selecting the STF1060.

Q: What is the difference between the TO-220-2 and TO-220-3 packages? A: The TO-220-2 package (used by STF1060) contains two leads, while the TO-220-3 package (used by TSF20H100C-S and VF30100S-E3/4W) contains three leads. These packages have different pin configurations and are not mechanically interchangeable on the same PCB layout.

Q: Can the VF30100S-E3/4W be used in applications designed for 10 A operation? A: Yes. The VF30100S-E3/4W is rated for 30 A average rectified current, making it suitable for applications designed for 10 A operation. The higher current rating provides additional thermal margin and design flexibility without compromising performance at lower current levels.

Q: What is the reverse leakage current difference between these parts? A: The TSF20H100C-S exhibits 150 µA reverse leakage at 100 V, the STF1060 exhibits 850 µA at 60 V, and the VF30100S-E3/4W exhibits 1 mA at 100 V. Applications sensitive to leakage current should account for these differences in circuit design.
