MBR16100CTH Equivalent & Substitute Parts

Part Overview

The MBR16100CTH is a Schottky diode array in a 1 Pair Common Cathode configuration rated for 100 V DC reverse voltage and 8 A average rectified current per diode. Manufactured by onsemi under the SWITCHMODE™ series, this through-hole TO-220-3 package component is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR16100CTH 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): 100 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Equal or greater than 8 A
• Voltage - Forward (Vf) (Max) @ If: Within acceptable circuit operating margins
• Current - Reverse Leakage @ Vr: Equal or lower than specified
• Operating Temperature - Junction: Must encompass or exceed the required range

Substitute parts are grouped into two categories: direct equivalents (identical electrical ratings) and similar alternatives (higher current ratings or enhanced specifications that maintain backward compatibility).

Parameter Comparison

Engineering Selection Recommendations

MBR16100CTG (onsemi): This part is a direct electrical equivalent to the MBR16100CTH with identical ratings across all critical parameters. The primary difference is packaging format (Tube versus unspecified). Both parts share obsolete product status. This substitute is suitable for applications requiring exact electrical performance matching. Higher inventory availability (6502 units) supports production continuity.

SR16100HC0G (Taiwan Semiconductor Corporation): This part provides a higher current rating of 16 A per diode, exceeding the 8 A requirement of the MBR16100CTH. Active product status ensures long-term availability. AEC-Q101 automotive qualification and Automotive grade designation provide enhanced reliability documentation. Operating temperature range (-55°C ~ 150°C) is narrower than the original part. Forward voltage is elevated at 900 mV @ 8 A. This substitute is applicable in designs where higher current capacity provides design margin and automotive-grade reliability is beneficial.

STPS40SM100CT (STMicroelectronics): This part offers the highest current rating at 20 A per diode with superior reverse leakage characteristics (45 µA @ 100 V versus 100 µA). Active product status ensures availability. Forward voltage specification is 810 mV @ 20 A. Operating temperature maximum is specified as 150°C without a minimum value provided. This substitute is suitable for applications requiring enhanced current handling and lower leakage performance.

VS-16CTQ100-M3 (Vishay General Semiconductor - Diodes Division): This part matches the 8 A current rating of the MBR16100CTH with identical voltage specifications. Active product status supports long-term procurement. Operating temperature range (-55°C ~ 175°C) encompasses the original specification. Forward voltage is 880 mV @ 16 A. Reverse leakage is elevated at 550 µA @ 100 V. This substitute provides direct current rating compatibility with active product status and extended temperature range capability.

Frequently Asked Questions (FAQ)

Q: Can MBR16100CTG be used as a direct replacement for MBR16100CTH?

A: Yes. MBR16100CTG is a direct electrical equivalent with identical Schottky diode array configuration, 100 V reverse voltage rating, 8 A current rating, and TO-220-3 package. Both parts are obsolete. The primary difference is packaging format (Tube). Electrical performance and circuit compatibility are identical.

Q: What is the difference between the MBR16100CTH and higher-current alternatives like SR16100HC0G or STPS40SM100CT?

A: SR16100HC0G and STPS40SM100CT provide higher current ratings (16 A and 20 A respectively) compared to the 8 A rating of MBR16100CTH. These parts maintain the same 100 V reverse voltage and TO-220-3 package. Higher current ratings provide design margin in applications where current demand may approach the original specification. Both alternatives are active products, ensuring long-term availability.

Q: Are all substitute parts compatible with the same PCB layout and thermal management design?

A: All substitute parts use the TO-220-3 package and through-hole mounting type, ensuring mechanical and thermal interface compatibility with existing PCB designs. Thermal performance may vary due to differences in current ratings and forward voltage characteristics. Designs utilizing higher-current substitutes may benefit from improved thermal margin.

Q: What compliance certifications apply to these substitute parts?

A: All listed parts are ROHS3 compliant and REACH unaffected. SR16100HC0G carries AEC-Q101 automotive qualification and Automotive grade designation, providing additional reliability documentation for automotive applications. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Which substitute part should be selected for new production designs?

A: Selection depends on application requirements. For designs requiring exact electrical matching with the original MBR16100CTH, use MBR16100CTG or VS-16CTQ100-M3. For applications benefiting from higher current capacity and active product status, select SR16100HC0G (automotive-qualified) or STPS40SM100CT (enhanced leakage performance). All active alternatives ensure long-term component availability.

Q: How do forward voltage differences affect circuit performance?

A: Forward voltage variations (740 mV to 900 mV across the substitute range) affect power dissipation and voltage drop across the diode array. Designs with tight voltage margin requirements should account for these differences. STPS40SM100CT offers the lowest forward voltage at 810 mV @ 20 A, while SR16100HC0G is highest at 900 mV @ 8 A.

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

A: Reverse leakage current affects standby power consumption and circuit performance in high-impedance applications. STPS40SM100CT provides the lowest leakage at 45 µA @ 100 V, while VS-16CTQ100-M3 is highest at 550 µA @ 100 V. The original MBR16100CTH specifies 100 µA @ 100 V. Applications sensitive to leakage current should prioritize STPS40SM100CT.
