Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSF40L200C is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• 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
• Supplier Device Package: ITO-220AB

Current Rating Consideration: The TSF40L200C operates at 20 A average rectified current per diode. Substitute parts may operate at different current ratings (5 A, 10 A, or 15 A). Selection of a substitute with lower current rating is permissible only when the application circuit does not require the full 20 A capability. Selection of a substitute with equal or higher current rating maintains full functional compatibility.

Forward Voltage Consideration: The TSF40L200C exhibits 980 mV forward voltage at 20 A. Substitute parts with different current ratings will exhibit different forward voltage characteristics at their respective rated currents. Forward voltage differences must be evaluated against specific circuit requirements.

Temperature Range Consideration: The TSF40L200C operates from -55°C to 150°C junction temperature. Substitute parts from the Vishay TMBS® series operate from -40°C to 150°C. Applications requiring operation below -40°C junction temperature cannot use these substitutes.

Compliance and Regulatory Status: All listed substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory equivalence with the main part.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent: The TSF40L200C itself remains available with 984 pieces in stock as new original inventory. This part maintains full electrical and mechanical compatibility with existing designs and requires no circuit modifications.

Active Product Alternatives: All listed substitute parts carry Active product status from Vishay General Semiconductor - Diodes Division, ensuring long-term availability and continued manufacturing support. These parts are suitable for new designs and design transitions.

Current Rating Selection:

VF30200C-E3/4W operates at 15 A average rectified current per diode, providing the closest current rating match to the TSF40L200C 20 A specification while maintaining Active product status. This part is suitable for applications where the full 20 A capability is not required but higher current capacity than 10 A is necessary.

VF20200C-E3/4W and VF20200G-E3/4W operate at 10 A average rectified current per diode. These parts are suitable for applications where circuit requirements do not exceed 10 A per diode.

VFT10200C-E3/4W operates at 5 A average rectified current per diode. This part is suitable for applications where circuit requirements do not exceed 5 A per diode.

Temperature Range Consideration: The TSF40L200C supports operation from -55°C to 150°C junction temperature. All Vishay TMBS® substitute parts support operation from -40°C to 150°C junction temperature. Applications requiring junction temperatures below -40°C cannot use the listed Vishay substitutes and must retain the TSF40L200C or identify alternative sources.

Compliance Status: All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory equivalence with the main part for applications subject to these requirements.

Frequently Asked Questions (FAQ)

Q: Can VF30200C-E3/4W be used as a direct replacement for TSF40L200C?

A: VF30200C-E3/4W is mechanically and electrically compatible with TSF40L200C in applications where the circuit does not require the full 20 A capability. Both parts share identical reverse voltage rating (200 V), diode configuration (1 Pair Common Cathode), technology (Schottky), mounting type (Through Hole), and package (TO-220-3 Full Pack, Isolated Tab). VF30200C-E3/4W operates at 15 A average rectified current per diode compared to TSF40L200C at 20 A. Forward voltage at rated current differs: VF30200C-E3/4W exhibits 1.1 V @ 15 A versus TSF40L200C at 980 mV @ 20 A. Temperature range differs: VF30200C-E3/4W operates from -40°C to 150°C versus TSF40L200C from -55°C to 150°C.

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

A: Both parts share identical electrical specifications except for forward voltage at rated current. VF20200C-E3/4W exhibits 1.6 V @ 10 A forward voltage, while VF20200G-E3/4W exhibits 1.7 V @ 10 A forward voltage. Both operate at 10 A average rectified current per diode, 200 V reverse voltage, and share identical package, mounting type, and temperature range (-40°C to 150°C). Selection between these parts depends on circuit requirements for forward voltage characteristics.

Q: Can a lower current-rated substitute be used in place of TSF40L200C?

A: A lower current-rated substitute is permissible only when the application circuit does not require the full 20 A capability. VF30200C-E3/4W (15 A), VF20200C-E3/4W (10 A), VF20200G-E3/4W (10 A), and VFT10200C-E3/4W (5 A) are all mechanically and electrically compatible with TSF40L200C in applications where circuit current requirements do not exceed the substitute part's rated current. Circuit analysis must confirm that maximum circuit current does not exceed the substitute part's average rectified current specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (VFT10200C-E3/4W, VF20200C-E3/4W, VF30200C-E3/4W, and VF20200G-E3/4W) maintain ROHS3 compliance, matching the compliance status of TSF40L200C. All parts also maintain MSL 1 (Unlimited) rating and REACH Unaffected status.

Q: What is the significance of the "Not For New Designs" status of TSF40L200C?

A: The "Not For New Designs" status indicates that Taiwan Semiconductor Corporation no longer recommends this part for new circuit development. However, the part remains available for existing designs and maintenance applications. All listed Vishay substitute parts carry Active product status, indicating ongoing manufacturing support and suitability for new designs and design transitions.

Q: Does package compatibility extend to all substitute parts?

A: Yes. All substitute parts utilize the TO-220-3 Full Pack with isolated tab package in the ITO-220AB supplier device package format, matching the mechanical and thermal characteristics of TSF40L200C. All parts are configured for through-hole mounting with identical pin configuration and thermal interface properties.

Q: What is the impact of reverse leakage current differences between parts?

A: TSF40L200C exhibits 100 µA reverse leakage current @ 200 V, while all Vishay substitute parts exhibit 150 µA (VFT10200C-E3/4W, VF20200C-E3/4W, VF20200G-E3/4W) or 160 µA (VF30200C-E3/4W) reverse leakage current @ 200 V. These differences are within typical Schottky diode specifications and do not affect functional compatibility in standard rectification applications. Applications with specific reverse leakage requirements must evaluate these differences against circuit specifications.

Q: Can TSF40L200C be used in applications requiring operation below -40°C junction temperature?

A: Yes. TSF40L200C supports operation from -55°C to 150°C junction temperature, extending 15°C lower than the Vishay TMBS® substitute parts which operate from -40°C to 150°C. Applications requiring junction temperatures below -40°C must retain TSF40L200C or identify alternative sources, as all listed Vishay substitutes have a -40°C minimum junction temperature specification.
