Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBR40100PTHC0G are qualified based on the following critical parameters that must remain constant or compatible:

Fixed Parameters (Must Match):

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Mounting Type: Through Hole
• Package / Case: TO-247-3
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Variable Parameters (Acceptable Range):

• Current - Average Rectified (Io) (per Diode): 15A to 40A
• Current - Reverse Leakage @ Vr: 5 µA to 500 µA @ 100 V
• Operating Temperature - Junction: -40°C to 175°C (minimum range must encompass application requirements)

The three STMicroelectronics substitute parts (STPS30H100CW, STPS40H100CW, STPS61H100CW) maintain identical voltage ratings, package configuration, and fast recovery characteristics. Variations in current ratings and reverse leakage characteristics are within acceptable substitution parameters for applications where the full 40A capability of the primary part is not required or where lower leakage performance is acceptable.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and full ROHS3 compliance with MSL 1 rating, ensuring compatibility with standard handling and storage protocols. The primary distinction between the MBR40100PTHC0G and its STMicroelectronics equivalents lies in current rating capacity and reverse leakage characteristics.

STPS30H100CW is suitable for applications requiring 15A or less per diode, offering the lowest reverse leakage specification at 5 µA @ 100 V and extended maximum junction temperature to 175°C.

STPS40H100CW provides 20A per diode capacity with 730 mV forward voltage at 20A and 10 µA reverse leakage, representing a mid-range current option with improved forward voltage characteristics.

STPS61H100CW delivers 30A per diode capacity with 790 mV forward voltage at 30A and 16 µA reverse leakage, approaching the full current capability of the primary part while maintaining all electrical and mechanical compatibility parameters.

Selection between substitute parts depends on application current requirements. The MBR40100PTHC0G remains the appropriate choice for applications requiring the full 40A per diode specification. For applications with lower current demands, the STMicroelectronics alternatives provide equivalent voltage and package compatibility with potentially improved leakage performance.

Frequently Asked Questions (FAQ)

Q: Can STPS30H100CW, STPS40H100CW, or STPS61H100CW be used as direct replacements for MBR40100PTHC0G?

A: Direct replacement depends on application current requirements. All substitute parts share identical voltage ratings (100 V), package configuration (TO-247-3), and fast recovery characteristics. However, current ratings differ: STPS30H100CW (15A), STPS40H100CW (20A), and STPS61H100CW (30A) versus MBR40100PTHC0G (40A). Substitution is valid only when application current per diode does not exceed the substitute part's rating.

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

A: Reverse leakage current values (5 µA to 500 µA @ 100 V) indicate the magnitude of current flowing through the diode in reverse bias condition. Lower leakage values reduce power dissipation and heat generation in standby or reverse bias states. The MBR40100PTHC0G specifies 500 µA, while STMicroelectronics substitutes range from 5 µA to 16 µA. Applications sensitive to leakage current may benefit from the lower leakage characteristics of the substitute parts.

Q: Are there temperature rating differences that affect substitution?

A: The MBR40100PTHC0G operates from -55°C to 150°C junction temperature. STPS30H100CW extends to -40°C to 175°C, while STPS40H100CW and STPS61H100CW specify maximum 175°C. For applications operating below -40°C, the MBR40100PTHC0G is required. For applications within -40°C to 150°C range, all parts are compatible.

Q: Do all parts maintain the same RoHS and MSL compliance?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 (Unlimited) rating, ensuring equivalent environmental compliance and handling requirements.

Q: What is the difference between the MBR40100PTHC0G and STPS61H100CW in practical applications?

A: Both parts share identical voltage ratings, package type, and fast recovery characteristics. The primary difference is current capacity: STPS61H100CW provides 30A per diode versus 40A for MBR40100PTHC0G. STPS61H100CW also exhibits significantly lower reverse leakage (16 µA versus 500 µA @ 100 V). For applications requiring 30A or less, STPS61H100CW is a valid substitute with improved leakage performance.

Q: Can these parts be used interchangeably in automotive applications?

A: The MBR40100PTHC0G carries AEC-Q101 automotive qualification. The STMicroelectronics substitute parts do not list AEC-Q101 qualification in the provided specifications. For applications requiring explicit automotive qualification, the MBR40100PTHC0G is the specified choice. For non-qualified automotive applications, substitutes may be evaluated based on current and temperature requirements.
