TSF40H200C Equivalent & Substitute Parts

Part Overview

The TSF40H200C is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as 1 pair common cathode with 200 V reverse voltage rating and 20 A average rectified current per diode. The device is packaged in TO-220-3 Full Pack with isolated tab for through-hole mounting applications.

The TSF40H200C carries a product status of "Not For New Designs," indicating it is obsolete or being phased out. Identification of equivalent and substitute parts is necessary for design continuity, procurement alternatives, and long-term supply chain management. Substitute parts must maintain electrical compatibility within the specified parameter ranges while accommodating application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSF40H200C is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 200 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack, Isolated Tab

Flexible Parameters (Application-Dependent):

• Current - Average Rectified (Io) (per Diode): Substitute parts may have lower current ratings if application requirements permit
• Voltage - Forward (Vf) (Max) @ If: Variations acceptable within application thermal and efficiency constraints
• Operating Temperature - Junction: Substitute parts with narrower temperature ranges are acceptable if application operates within specified limits

All substitute parts listed maintain the 200 V reverse voltage specification, Schottky technology, common cathode configuration, and TO-220-3 package format. Differences in current ratings and forward voltage characteristics reflect manufacturing variations and product series designations from Vishay General Semiconductor - Diodes Division (TMBS® series).

Engineering Selection Recommendations

Primary Substitute: VF30200C-E3/4W

The VF30200C-E3/4W is the recommended substitute for the TSF40H200C. This part maintains full electrical and mechanical compatibility with identical 200 V reverse voltage rating, Schottky technology, common cathode configuration, and TO-220-3 package format. The VF30200C-E3/4W carries Active product status, ensuring long-term availability and supply chain continuity. Current rating of 15 A per diode accommodates applications requiring up to 15 A; applications requiring the full 20 A rating of the original TSF40H200C require evaluation of thermal management and circuit design.

Secondary Substitutes: VF20200C-E3/4W and VF20200G-E3/4W

Both VF20200C-E3/4W and VF20200G-E3/4W are functionally equivalent with 10 A current rating per diode. These parts are suitable for applications with current requirements up to 10 A. Both maintain Active product status and full compliance with ROHS3 and MSL specifications. Selection between these two variants depends on forward voltage characteristics acceptable to the application.

Lower Current Alternative: VFT10200C-E3/4W

The VFT10200C-E3/4W provides a 5 A per diode option for applications with reduced current requirements. This part maintains all critical electrical and mechanical parameters and carries Active product status.

All substitute parts are manufactured by Vishay General Semiconductor - Diodes Division within the TMBS® series, carry ROHS3 compliance, and maintain MSL 1 (Unlimited) rating. Operating temperature range for all Vishay substitutes is -40 to 150 °C, which is narrower than the original TSF40H200C (-55 to 150 °C); applications requiring operation below -40 °C require verification against specific design requirements.

Frequently Asked Questions (FAQ)

Q: Can VF30200C-E3/4W directly replace TSF40H200C in all applications?

A: VF30200C-E3/4W maintains identical voltage rating (200 V), technology (Schottky), configuration (1 pair common cathode), and package (TO-220-3 Full Pack, Isolated Tab). The 15 A current rating is lower than the original 20 A rating. Direct replacement is valid for applications requiring 15 A or less per diode. Applications requiring the full 20 A rating require circuit redesign or parallel device configuration.

Q: What is the difference between VF20200C-E3/4W and VF20200G-E3/4W?

A: Both parts are electrically and mechanically identical with the following exception: VF20200C-E3/4W specifies maximum forward voltage of 1.6 V @ 10 A, while VF20200G-E3/4W specifies 1.7 V @ 10 A. Selection depends on application thermal budget and efficiency requirements. Both maintain 200 V reverse voltage, Schottky technology, common cathode configuration, and TO-220-3 package format.

Q: Why does the TSF40H200C have "Not For New Designs" status?

A: This status indicates the part is obsolete or being phased out by the manufacturer. Active substitute parts from Vishay General Semiconductor - Diodes Division (VF20200C-E3/4W, VF20200G-E3/4W, VF30200C-E3/4W, VFT10200C-E3/4W) are recommended for new designs and ongoing production.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and MSL 1 (Unlimited) rating, matching the compliance profile of the original TSF40H200C.

Q: What is the minimum operating temperature for substitute parts?

A: All Vishay substitute parts specify operating temperature range of -40 to 150 °C. The original TSF40H200C specifies -55 to 150 °C. Applications requiring operation below -40 °C must verify compatibility with specific design requirements or consider alternative solutions.

Q: Can multiple lower-current parts be paralleled to achieve 20 A operation?

A: Parallel configuration of Schottky diodes requires careful thermal management and current balancing design. This approach is outside the scope of direct substitution and requires detailed circuit analysis and thermal modeling specific to the application.

Q: Are the TO-220-3 packages of all parts physically identical?

A: All listed parts use TO-220-3 Full Pack with Isolated Tab package format. Physical dimensions and pin configurations are identical, enabling direct mechanical replacement on printed circuit boards.
