Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSA10I100PM is determined by the following critical parameters:

Voltage Rating Compatibility: The substitute part must maintain the 100V DC reverse voltage specification to ensure circuit protection and reliability.

Current Rating Consideration: The DSA10I100PM operates at 10A average rectified current. Substitute parts with lower current ratings (such as 8A) operate within reduced current capacity and must be evaluated for application-specific current demands.

Package and Mounting: Both the main part and substitute must use TO-220-2 Full Pack with isolated tab configuration to ensure mechanical and thermal compatibility with existing PCB layouts and heatsinking arrangements.

Technology and Speed: Fast recovery Schottky technology with switching speed ≤ 500ns is maintained across substitute selections to preserve circuit performance characteristics.

Thermal Operating Range: The substitute part must support the required junction temperature range for the application environment.

Compliance Standards: RoHS3 compliance and REACH unaffected status are maintained across all substitute options.

Engineering Selection Recommendations

DSA10I100PM (IXYS): Primary selection for applications requiring 10A average rectified current capacity. Active product status with established supply chain. RoHS3 compliant and REACH unaffected. Suitable for designs with thermal management supporting -55°C to 150°C junction temperature range.

STPS8H100FP (STMicroelectronics): Suitable for applications with maximum current requirements of 8A or less. Offers improved reverse leakage characteristics (4.5 µA versus 200 µA) and extended maximum junction temperature rating (175°C versus 150°C). Active product status with higher inventory availability. RoHS3 compliant and REACH unaffected. Lower forward voltage drop at rated current improves thermal efficiency in power conversion applications.

Both parts maintain identical voltage ratings, fast recovery switching characteristics, and TO-220FP package compatibility. Selection between these parts depends on application current requirements and thermal design constraints.

Frequently Asked Questions (FAQ)

Q: Can STPS8H100FP replace DSA10I100PM in all applications?

A: STPS8H100FP is suitable only for applications where the maximum average rectified current does not exceed 8A. If the circuit design requires sustained 10A operation, the DSA10I100PM is the appropriate selection. Both parts share identical 100V voltage ratings and TO-220FP package specifications.

Q: What is the significance of the current rating difference between these parts?

A: The DSA10I100PM is rated for 10A average rectified current, while STPS8H100FP is rated for 8A. This difference directly impacts the maximum continuous current the diode can conduct without exceeding thermal limits. Applications operating above 8A require the DSA10I100PM.

Q: Are the package dimensions identical between DSA10I100PM and STPS8H100FP?

A: Both parts use TO-220-2 Full Pack with isolated tab configuration. This ensures mechanical compatibility with existing PCB layouts and heatsinking arrangements. The supplier device packages differ (TO-220FP versus TO-220FPAC), but both conform to the same TO-220-2 standard footprint.

Q: How do the reverse leakage characteristics compare?

A: STPS8H100FP exhibits significantly lower reverse leakage current (4.5 µA @ 100V) compared to DSA10I100PM (200 µA @ 100V). Lower leakage reduces standby power consumption and heat generation in applications with sustained reverse bias conditions.

Q: What is the thermal operating range difference?

A: DSA10I100PM operates from -55°C to 150°C junction temperature. STPS8H100FP supports a maximum junction temperature of 175°C, providing 25°C additional thermal margin. This difference may be relevant for high-temperature applications or designs with limited heatsinking capacity.

Q: Are both parts RoHS3 compliant?

A: Yes. Both DSA10I100PM and STPS8H100FP are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the forward voltage drop difference at rated current?

A: At their respective rated currents, DSA10I100PM exhibits 890 mV forward voltage drop at 10A, while STPS8H100FP exhibits 710 mV at 8A. Direct comparison at identical current levels is not provided in the specifications. Lower forward voltage drop reduces power dissipation and improves efficiency in rectification circuits.
