Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBRB20150CT-13 are qualified based on the following criteria:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 150 V
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount

Allowable Parameter Variations:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 10 A
• Voltage - Forward (Vf) (Max) @ If: Within acceptable forward voltage characteristics for Schottky technology
• Current - Reverse Leakage @ Vr: Lower values indicate improved performance
• Operating Temperature - Junction: Must support the required operating range
• Product Status: Active
• Compliance: ROHS3 Compliant, REACH Unaffected

The STPS40150CG from STMicroelectronics qualifies as a substitute because it maintains identical configuration, voltage rating, and package specifications while providing enhanced current handling capability (20 A versus 10 A per diode).

Engineering Selection Recommendations

MBRB20150CT-13 (Diodes Incorporated)

Select this part when the application requires a 10 A per diode Schottky rectifier array with automotive-grade qualification (AEC-Q101). This device is suitable for standard rectification applications operating within the 150 V reverse voltage specification. The part maintains active production status with established supply availability.

STPS40150CG (STMicroelectronics)

Select this part as a substitute when the application requires higher current handling capability (20 A per diode) while maintaining the same 150 V reverse voltage rating and TO-263-3 package footprint. The STPS40150CG provides improved reverse leakage characteristics (8 µA versus 50 µA at 150 V), resulting in lower standby power dissipation. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Both parts are active in production and suitable for automotive applications. The selection between these parts depends on the specific current requirements of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the STPS40150CG replace the MBRB20150CT-13 in existing designs?

A: Yes. The STPS40150CG is a direct substitute from a package and electrical configuration standpoint. Both devices use the TO-263-3 (D2PAK) package with identical pinout and mounting requirements. The STPS40150CG provides higher current capability (20 A versus 10 A per diode) and lower reverse leakage current, making it suitable for applications designed for the MBRB20150CT-13.

Q: Are there any thermal considerations when substituting these parts?

A: Both parts share the same maximum junction temperature rating of 175°C and identical package type. Thermal performance depends on PCB layout, copper area, and thermal vias. The STPS40150CG's lower reverse leakage current (8 µA versus 50 µA) results in reduced standby power dissipation.

Q: Do both parts meet automotive qualification requirements?

A: The MBRB20150CT-13 carries AEC-Q101 automotive qualification. The STPS40150CG is manufactured by STMicroelectronics and maintains ROHS3 compliance and REACH unaffected status. Verify specific automotive qualification requirements with the application's quality and compliance documentation.

Q: What is the significance of the reverse voltage rating of 150 V for both parts?

A: The 150 V DC reverse voltage rating (Vr) is the maximum voltage that can be applied across the diode in reverse bias without exceeding the reverse leakage specification. Both the MBRB20150CT-13 and STPS40150CG are rated for identical 150 V reverse voltage, ensuring compatibility in circuits designed for this voltage class.

Q: How do the forward voltage characteristics compare between these parts?

A: The MBRB20150CT-13 specifies 900 mV maximum forward voltage at 10 A, while the STPS40150CG specifies 920 mV maximum at 20 A. Both values are typical for Schottky diode technology at their respective current ratings. Forward voltage drop increases with current, which is reflected in the higher specification for the higher-current STPS40150CG.

Q: Are there packaging or handling differences between these parts?

A: Both parts are supplied in surface mount TO-263-3 (D2PAK) packages with identical moisture sensitivity level (MSL 1 - Unlimited). The MBRB20150CT-13 is supplied in Tape & Reel (TR) packaging, while the STPS40150CG is supplied in Tube packaging. Both packaging formats are standard for surface mount assembly processes.

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

A: This configuration indicates the diode array contains two independent Schottky diodes with a shared cathode connection. The common cathode pin is the tab on the TO-263-3 package. This configuration is standard for bridge rectifier and dual rectification applications.
