Technology: Schottky
Voltage - DC Reverse (Vr) (Max): 200 V minimum
Mounting Type: Through Hole
Package / Case: TO-220-3 or compatible variant

Current Rating Considerations: Substitute parts are grouped by average rectified current capacity. The MBR20200CTH operates at 20 A per diode. Substitutes with equal or higher current ratings (20 A or greater) provide direct replacement capability. Substitutes with lower current ratings (10 A, 15 A, or 5 A) are classified as similar alternatives suitable only when application current requirements are lower than the original specification.

Compliance and Packaging: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. Packaging variants include standard TO-220-3 through-hole and isolated tab configurations (ITO-220AB). Tube and bulk packaging options are available depending on sourcing requirements.

Engineering Selection Recommendations

Direct Equivalents (20 A Current Rating):

MBR20200CT-BP (Micro Commercial Co) and MBR20200CTH share identical electrical specifications at 20 A average rectified current and 200 V reverse voltage. Both parts are ROHS3 compliant and MSL 1 rated. MBR20200CT-BP is available in bulk packaging, whereas the main part is supplied in tube packaging. Both are active products suitable for direct substitution in applications requiring full 20 A capacity.

Compatible Substitutes (10 A Current Rating):

MBR20200CT-G1 (Diodes Incorporated), V20202C-M3/4W (Vishay), and MBR20200CT (Good-Ark Semiconductor) are rated at 10 A average rectified current. These parts maintain 200 V reverse voltage and fast recovery speed characteristics. MBR20200CT-G1 and V20202C-M3/4W both specify operating temperature ranges extending to 175°C, exceeding the main part's 150°C maximum. These substitutes are suitable for applications where current requirements do not exceed 10 A per diode.

Reduced Current Alternatives:

V30202C-M3/4W (Vishay) operates at 15 A and MBR10200CT-G1 (Diodes Incorporated) at 5 A. Both maintain 200 V reverse voltage and Schottky technology. These parts are suitable only when application current demands are lower than the original specification.

Compliance Status:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating, consistent with the main part's environmental and regulatory qualifications. The main part carries AEC-Q101 automotive qualification; substitute parts should be evaluated for automotive grade requirements in specific applications.

Frequently Asked Questions (FAQ)

Q: Can MBR20200CT-BP replace MBR20200CTH directly?

A: Yes. MBR20200CT-BP is a direct electrical equivalent with identical 20 A current rating and 200 V reverse voltage specification. The primary difference is packaging format: MBR20200CT-BP is supplied in bulk, while MBR20200CTH is supplied in tube. Both are ROHS3 compliant and MSL 1 rated.

Q: What is the difference between MBR20200CT-G1 and MBR20200CTH?

A: MBR20200CT-G1 is rated at 10 A average rectified current, whereas MBR20200CTH is rated at 20 A. Both share 200 V reverse voltage, Schottky technology, and TO-220-3 through-hole packaging. MBR20200CT-G1 is suitable only for applications where current requirements do not exceed 10 A per diode.

Q: Are Vishay V20202C-M3/4W and V30202C-M3/4W interchangeable with MBR20200CTH?

A: V20202C-M3/4W (10 A) and V30202C-M3/4W (15 A) are not direct replacements for the 20 A rated MBR20200CTH. Both Vishay parts maintain 200 V reverse voltage and fast recovery speed. They are suitable substitutes only when application current requirements are lower than the original 20 A specification. Both Vishay parts extend operating temperature to 175°C compared to MBR20200CTH's 150°C maximum.

Q: What does "1 Pair Common Cathode" configuration mean?

A: This configuration indicates the diode array contains two diodes sharing a common cathode terminal. All substitute parts listed maintain this same configuration, ensuring pin-compatible operation in circuits designed for the MBR20200CTH.

Q: Is the isolated tab variant (ITO-220AB) compatible with standard TO-220-3 applications?

A: The MBR20200CT from Good-Ark Semiconductor features an isolated tab variant (ITO-220AB). While mechanically similar to standard TO-220-3, the isolated tab provides electrical isolation between the tab and the cathode. Compatibility depends on circuit design; isolated tab variants are suitable when tab isolation is required or beneficial.

Q: Which substitute part has the lowest forward voltage drop?

A: V30202C-M3/4W (Vishay) specifies 880 mV forward voltage at 15 A, the lowest among parts with specified forward voltage values. However, this part is rated at 15 A, not 20 A. For 20 A operation, MBR20200CT-BP specifies 950 mV at 10 A, which is lower than MBR20200CTH's 1.23 V at 20 A.

Q: Are all substitute parts automotive qualified?

A: The main part MBR20200CTH carries AEC-Q101 automotive qualification. Substitute parts listed do not explicitly state automotive qualification in the provided specifications. Applications requiring automotive grade components should verify qualification status with manufacturers before selection.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current varies among substitutes: MBR20200CT (Good-Ark) specifies 200 nA, while others range from 50 µA to 250 µA at 200 V. Lower leakage current indicates better reverse blocking characteristics. Differences are significant in high-impedance or precision applications; standard rectification applications are generally unaffected by these variations.
