Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRS25100CT is determined by the following critical parameters:

Mandatory Matching Criteria:

• Diode configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Flexible Parameters (Application-Dependent):

• Current - Average Rectified (Io) (per Diode): May be lower if application current requirements permit
• Voltage - Forward (Vf) (Max): Variation acceptable within circuit design margins
• Operating Temperature - Junction: Maximum rating may differ based on thermal design

The STPS10H100CG-TR qualifies as a substitute part based on matching diode configuration, voltage rating, package type, and fast recovery speed characteristics. The current rating of 5 A per diode is lower than the 25 A specification of the MBRS25100CT and restricts its use to applications with reduced current requirements.

Parameter Comparison

Engineering Selection Recommendations

MBRS25100CT (Primary Part): Select this part for applications requiring 25 A average rectified current per diode at 100 V reverse voltage. The part is active, RoHS3 compliant, and REACH unaffected. Operating temperature range of -55°C to 150°C supports standard industrial and commercial applications. Forward voltage of 920 mV at 25 A is specified for high-current operation.

STPS10H100CG-TR (Substitute Part): This part is suitable for applications with reduced current requirements up to 5 A per diode at 100 V reverse voltage. The part is active, RoHS3 compliant, and REACH unaffected. Maximum junction temperature of 175°C provides extended thermal headroom compared to the primary part. Lower reverse leakage current of 3.5 µA at 100 V and lower forward voltage of 730 mV at 5 A indicate improved efficiency in lower-current applications. Moisture sensitivity level (MSL) of 1 indicates unlimited shelf life.

Both parts share identical package configuration (TO-263-3, D2PAK), diode configuration (1 Pair Common Cathode), voltage rating (100 V), and fast recovery speed characteristics, ensuring mechanical and electrical compatibility within their respective current ratings.

Frequently Asked Questions (FAQ)

Q: Can STPS10H100CG-TR replace MBRS25100CT in all applications?

A: No. The STPS10H100CG-TR has a maximum average rectified current of 5 A per diode, compared to 25 A for the MBRS25100CT. Substitution is valid only for applications where the circuit current requirement does not exceed 5 A per diode.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use TO-263-3 (D2PAK) surface mount package with 2 leads plus tab configuration. PCB footprints and thermal interface requirements are identical.

Q: What is the difference in forward voltage between these parts?

A: The MBRS25100CT specifies 920 mV forward voltage at 25 A, while the STPS10H100CG-TR specifies 730 mV at 5 A. Forward voltage varies with current; direct comparison at different current levels is not applicable.

Q: Do both parts have the same reverse voltage rating?

A: Yes. Both parts have a maximum DC reverse voltage (Vr) of 100 V and are suitable for identical voltage-class applications.

Q: What is the difference in reverse leakage current?

A: The MBRS25100CT has reverse leakage of 100 µA at 100 V, while the STPS10H100CG-TR has 3.5 µA at 100 V. Lower leakage in the substitute part indicates reduced standby power dissipation in low-current applications.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the maximum operating temperature for each part?

A: The MBRS25100CT operates from -55°C to 150°C junction temperature. The STPS10H100CG-TR has a maximum junction temperature of 175°C, providing 25°C additional thermal margin.

Q: Do both parts have identical fast recovery characteristics?

A: Yes. Both parts specify fast recovery speed of ≤ 500ns for currents greater than 200mA (Io), ensuring equivalent switching performance in rectification circuits.
