Engineering Selection Recommendations

MBR40200PTH (Main Part): The MBR40200PTH is suitable for applications requiring a 40 A Schottky diode array with Automotive grade qualification and AEC-Q101 certification. This part is recommended for automotive and mission-critical applications where AEC-Q101 compliance is mandatory.

APT30S20BCTG (Substitute): The APT30S20BCTG provides a 45 A current rating, exceeding the main part specification. This substitute is applicable in applications where higher current capacity is required within the same 200 V voltage class. The forward voltage is lower at 830 mV @ 30 A compared to the main part. Reverse leakage is higher at 500 µA @ 200 V. This part is suitable for non-automotive applications or where automotive qualification is not required.

STPS60SM200CW (Substitute): The STPS60SM200CW provides the highest current rating at 60 A, offering significant current margin above the main part specification. This substitute features the lowest reverse leakage at 50 µA @ 200 V and an extended operating temperature range to 175°C. The forward voltage is 830 mV @ 30 A. This part is recommended for high-current applications or where superior leakage characteristics and thermal performance are beneficial.

Selection Criteria:

• All three parts are Active products with ROHS3 compliance
• All three parts maintain the same 200 V voltage rating and TO-247-3 package
• Current rating selection depends on application requirements: 40 A (main), 45 A (APT30S20BCTG), or 60 A (STPS60SM200CW)
• Automotive grade and AEC-Q101 qualification are specific to the MBR40200PTH
• Thermal performance and leakage characteristics vary among the three options

Frequently Asked Questions (FAQ)

Q: Can APT30S20BCTG be used as a direct replacement for MBR40200PTH?

A: APT30S20BCTG is electrically compatible as a substitute within the same functional category. Both devices share identical diode configuration (1 Pair Common Cathode), technology (Schottky), voltage rating (200 V), mounting type (Through Hole), and package (TO-247-3). The APT30S20BCTG provides higher current capacity (45 A vs. 40 A) and lower forward voltage. However, the MBR40200PTH carries Automotive grade and AEC-Q101 qualification, which APT30S20BCTG does not specify. Substitution is valid for applications where automotive qualification is not required.

Q: What is the difference between STPS60SM200CW and MBR40200PTH?

A: Both devices are 200 V Schottky diode arrays in TO-247-3 packages with identical diode configuration and fast recovery characteristics. The primary differences are: (1) Current rating: STPS60SM200CW is rated for 60 A versus 40 A for MBR40200PTH; (2) Reverse leakage: STPS60SM200CW has 50 µA @ 200 V versus 100 µA for MBR40200PTH; (3) Operating temperature range: STPS60SM200CW extends to 175°C versus 150°C for MBR40200PTH; (4) Automotive qualification: MBR40200PTH carries AEC-Q101 certification while STPS60SM200CW does not specify this qualification.

Q: Are all three parts RoHS compliant?

A: Yes. MBR40200PTH, APT30S20BCTG, and STPS60SM200CW are all ROHS3 Compliant. All three parts are also REACH Unaffected and carry EAR99 ECCN classification.

Q: What is the significance of the TO-247-3 package for these diodes?

A: The TO-247-3 package is a Through Hole surface mount package with three leads, designed for high-current applications. All three substitute parts use this identical package, ensuring mechanical and thermal compatibility in PCB layouts. The package provides robust thermal dissipation suitable for 40 A to 60 A current ratings.

Q: How do forward voltage specifications compare among the three parts?

A: The MBR40200PTH specifies 1.01 V @ 40 A forward voltage. APT30S20BCTG and STPS60SM200CW both specify 830 mV @ 30 A. Direct comparison at identical current levels is not available from the provided specifications. Forward voltage characteristics are technology-dependent and influence power dissipation in the application circuit.

Q: Which part should be selected for maximum current capacity?

A: STPS60SM200CW provides the highest current rating at 60 A per diode, offering the greatest current margin. This part is suitable for applications requiring maximum current handling capability within the 200 V voltage class.

Q: Is automotive qualification important for my application?

A: Automotive qualification and AEC-Q101 certification are mandatory for automotive and safety-critical applications. Only MBR40200PTH carries this qualification among the three parts. For non-automotive industrial or consumer applications, APT30S20BCTG or STPS60SM200CW are acceptable substitutes based on electrical compatibility.
