MBR20100CT-1 Equivalent & Substitute Parts

Part Overview

The MBR20100CT-1 is a Schottky diode array manufactured by Vishay General Semiconductor - Diodes Division. This component features a 1 Pair Common Cathode configuration rated for 100 V DC reverse voltage and 10 A average rectified current per diode. The device is packaged in a TO-262-3 (I2PAK) through-hole format with long leads.

The MBR20100CT-1 is classified as obsolete. Identification of equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBR20100CT-1 are qualified based on the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Current - Average Rectified (Io) (per Diode): 10 A minimum
• Diode Configuration: 1 Pair Common Cathode
• Operating Temperature - Junction: Must support -65°C minimum and 150°C maximum

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: TO-262-3 Long Leads, I2PAK, TO-262AA

Both substitute parts listed below meet these core requirements and maintain functional equivalence with the original MBR20100CT-1 component.

Parameter Comparison

Engineering Selection Recommendations

SBR20A100CTE is an active substitute manufactured by Diodes Incorporated. This part maintains electrical equivalence with the MBR20100CT-1 across all critical parameters: 100 V reverse voltage rating, 10 A average rectified current, and TO-262-3 package compatibility. The SBR20A100CTE achieves ROHS3 compliance and supports an extended operating temperature range of -65°C to 175°C, exceeding the original specification. Forward voltage is reduced to 750 mV at 10 A, representing improved efficiency. Reverse leakage remains at 100 µA at 100 V.

SBR20U100CTE-G is an active substitute also manufactured by Diodes Incorporated. This part meets all core electrical and mechanical requirements for direct substitution. The SBR20U100CTE-G achieves ROHS3 compliance and supports the extended operating temperature range of -65°C to 175°C. Forward voltage is further reduced to 700 mV at 10 A. Reverse leakage is specified at 500 µA at 100 V, which remains within acceptable limits for most applications but represents a higher leakage characteristic compared to the original part.

Both substitute parts are currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete MBR20100CT-1.

Frequently Asked Questions (FAQ)

Q: Can the SBR20A100CTE directly replace the MBR20100CT-1 in existing designs?

A: Yes. The SBR20A100CTE maintains identical electrical ratings (100 V, 10 A) and package configuration (TO-262-3). Both parts feature 1 Pair Common Cathode diode arrays with through-hole mounting. The extended temperature range (-65°C to 175°C) and improved forward voltage characteristics (750 mV vs. 800 mV at 10 A) provide enhanced performance margins.

Q: What is the difference between the SBR20A100CTE and SBR20U100CTE-G?

A: Both parts share identical voltage ratings, current ratings, and package specifications. The primary differences are forward voltage and reverse leakage characteristics. The SBR20A100CTE specifies 750 mV forward voltage and 100 µA reverse leakage at 100 V. The SBR20U100CTE-G specifies 700 mV forward voltage and 500 µA reverse leakage at 100 V. Selection depends on application requirements for forward voltage drop and reverse leakage performance.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both SBR20A100CTE and SBR20U100CTE-G are ROHS3 compliant. The original MBR20100CT-1 is RoHS non-compliant. This compliance upgrade may be required for new designs or applications subject to RoHS regulations.

Q: What is the difference between Schottky and Super Barrier diode technologies?

A: The MBR20100CT-1 uses Schottky technology with fast recovery characteristics (≤ 500 ns). The substitute parts use Super Barrier technology with standard recovery characteristics (> 500 ns). Both technologies are suitable for rectification applications. Recovery speed differences are not significant for most low-frequency rectification circuits but may affect performance in high-frequency switching applications.

Q: Are the packages physically identical?

A: Yes. All three parts use the TO-262-3 package with long leads (I2PAK, TO-262AA). Physical dimensions, lead spacing, and mounting hole patterns are identical, enabling direct PCB compatibility without layout modifications.

Q: What is the temperature range difference between the original and substitute parts?

A: The MBR20100CT-1 operates from -65°C to 150°C. Both substitute parts operate from -65°C to 175°C. The 25°C extended upper temperature limit provides additional thermal margin for high-temperature applications.
