Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRF20200CT is determined by the following critical parameters:

Mandatory Matching Parameters:

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

Current Rating Consideration: The MBRF20200CT specifies 10 A average rectified current per diode. Substitute parts may operate at equal or lower current ratings, provided all other electrical and mechanical parameters remain compatible.

Allowable Variations:

• Forward voltage (Vf) may vary within typical manufacturing tolerances
• Reverse leakage current may differ based on manufacturer process
• Operating temperature range may be narrower in substitute parts
• Product status may transition from Obsolete to Active

Two substitute parts are identified based on these criteria:

1. DSTF10200C (Littelfuse Inc.) — Active status, reduced current rating (5 A), narrower temperature range
2. MBRF20200CT (Good-Ark Semiconductor) — Active status, equivalent current rating (10 A), identical electrical specifications

Parameter Comparison

Engineering Selection Recommendations

MBRF20200CT (Good-Ark Semiconductor)

This substitute is the primary equivalent for the obsolete Diodes Incorporated MBRF20200CT. Both parts share identical current ratings (10 A), voltage specifications (200 V), and package configuration (TO-220-3 Full Pack, Isolated Tab). The Good-Ark version is currently in Active product status with full inventory availability (22,800 pcs). Both versions are ROHS3 compliant and carry MSL 1 classification. This substitute provides direct functional replacement with no design modifications required.

DSTF10200C (Littelfuse Inc.)

This substitute is applicable only in applications where the circuit design permits operation at reduced current levels (5 A per diode versus 10 A). The DSTF10200C maintains the same 200 V reverse voltage rating, Schottky technology, and TO-220-3 package configuration. The operating temperature range is narrower (-55 to 150 °C versus -55 to 175 °C). This part is suitable for designs with lower current requirements or where thermal derating is acceptable. The DSTF10200C is Active status with 851 pcs in stock.

Both substitutes are ROHS3 compliant and carry AEC-Q101 automotive qualification where applicable.

Frequently Asked Questions (FAQ)

Q: Can the DSTF10200C replace the MBRF20200CT in all applications?

A: The DSTF10200C is a valid substitute only when the circuit design operates at or below 5 A per diode. Applications requiring the full 10 A rating must use the Good-Ark MBRF20200CT or equivalent 10 A rated devices. The narrower operating temperature range (-55 to 150 °C) must also be verified against application requirements.

Q: Are the TO-220-3 packages mechanically interchangeable?

A: Yes. Both the DSTF10200C and Good-Ark MBRF20200CT use the TO-220-3 Full Pack with isolated tab package configuration (ITO-220AB supplier designation). Pin assignments and mechanical dimensions are identical, allowing direct board-level substitution without PCB modifications.

Q: What is the significance of the "1 Pair Common Cathode" configuration?

A: This configuration indicates the diode array contains two independent diodes sharing a common cathode connection. The three-pin TO-220-3 package provides two anode pins and one common cathode pin. Substitutes must maintain this exact configuration to ensure circuit compatibility.

Q: How do reverse leakage current differences affect circuit performance?

A: The three parts exhibit different reverse leakage characteristics: MBRF20200CT (Diodes Inc.) at 100 µA, DSTF10200C at 10 µA, and MBRF20200CT (Good-Ark) at 200 nA. Lower leakage is generally favorable in high-impedance circuits. Applications with strict leakage requirements should specify the Good-Ark version.

Q: Is the Littelfuse DSTF10200C suitable for automotive applications?

A: The DSTF10200C is ROHS3 compliant and carries MSL 1 classification. However, automotive qualification status (AEC-Q101) is not specified in the provided data. Automotive applications requiring AEC-Q101 certification should confirm qualification status with the manufacturer before selection.

Q: What is the difference between "Fast Recovery" and "Small Signal" speed classifications?

A: The original MBRF20200CT (Diodes Inc.) and DSTF10200C specify Fast Recovery speed (≤ 500ns for currents > 200mA). The Good-Ark MBRF20200CT specifies Small Signal speed (≤ 200mA). Speed classification affects switching characteristics and reverse recovery behavior. Applications with specific switching frequency requirements should verify speed specifications.

Q: Can I use the Good-Ark MBRF20200CT as a direct replacement without circuit redesign?

A: Yes. The Good-Ark MBRF20200CT maintains all critical electrical parameters of the original Diodes Incorporated part: 200 V reverse voltage, 10 A current rating, Schottky technology, and TO-220-3 package. No circuit modifications are required for direct substitution.
