Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS16170CT is determined by strict adherence to the following electrical and mechanical parameters:

Configuration Compatibility: The substitute part must maintain a 1 Pair Common Cathode diode array configuration to ensure pin-level compatibility with existing circuit designs.

Technology Requirement: Schottky diode technology is mandatory for the substitute to preserve the fast recovery characteristics and forward voltage performance of the original component.

Voltage Rating: The substitute part must have a maximum reverse voltage (Vr) rating equal to or greater than 170 V to ensure safe operation across the full voltage range of the original design.

Current Rating: The substitute part must have an average rectified current (Io) rating equal to or greater than 8 A per diode to support the thermal and electrical load requirements of the application.

Package Compatibility: The substitute must use the TO-220-3 Through Hole package to maintain mechanical fit and thermal management characteristics in the target application.

Speed Characteristics: Fast recovery performance (≤ 500ns, > 200mA) must be maintained to preserve switching frequency and efficiency performance.

Compliance Standards: The substitute part must maintain ROHS3 compliance and REACH Unaffected status to satisfy regulatory and supply chain requirements.

Parameter Comparison

Engineering Selection Recommendations

The MBR20200CTG from onsemi is a qualified substitute for the STPS16170CT based on the following engineering criteria:

Electrical Compatibility: The MBR20200CTG meets or exceeds all critical electrical parameters. The 200 V reverse voltage rating provides a 30 V margin above the 170 V requirement of the original design. The 10 A current rating exceeds the 8 A specification, providing additional thermal headroom. Forward voltage performance is equivalent or superior at the respective current levels.

Configuration and Package: Both parts maintain identical diode array configuration (1 Pair Common Cathode) and TO-220-3 Through Hole packaging, ensuring direct mechanical and electrical compatibility at the board level.

Technology and Performance: Both parts employ Schottky technology with identical fast recovery characteristics (≤ 500ns, > 200mA), preserving switching frequency and efficiency performance in the target application.

Regulatory Compliance: The MBR20200CTG maintains ROHS3 compliance and REACH Unaffected status, satisfying all regulatory requirements equivalent to the original component.

Product Availability: The MBR20200CTG is classified as Active, ensuring long-term availability and supply chain continuity compared to the Obsolete status of the STPS16170CT.

Reverse Leakage Consideration: The MBR20200CTG exhibits higher reverse leakage current (1 mA @ 200 V) compared to the STPS16170CT (15 µA @ 170 V). This parameter difference must be evaluated within the specific application context to determine if the increased leakage is acceptable for the intended circuit function.

Frequently Asked Questions (FAQ)

Q: Can the MBR20200CTG be used as a direct replacement for the STPS16170CT?

A: The MBR20200CTG is electrically and mechanically compatible with the STPS16170CT at the package and pin level. Both parts share identical TO-220-3 configuration and 1 Pair Common Cathode arrangement. The substitute part meets or exceeds all voltage and current specifications. However, the higher reverse leakage current of the MBR20200CTG must be evaluated within the specific application circuit to confirm functional equivalence.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (STMicroelectronics versus onsemi), product status (Obsolete versus Active), and reverse leakage current specification. The MBR20200CTG provides higher voltage and current ratings (200 V / 10 A versus 170 V / 8 A) and superior forward voltage performance. The MBR20200CTG exhibits higher reverse leakage (1 mA @ 200 V versus 15 µA @ 170 V).

Q: Are the pin configurations identical?

A: Yes. Both the STPS16170CT and MBR20200CTG use the TO-220-3 Through Hole package with identical pin assignments for a 1 Pair Common Cathode diode array configuration. Direct board-level substitution is mechanically feasible.

Q: Does the higher voltage rating of the MBR20200CTG affect circuit operation?

A: The higher voltage rating (200 V versus 170 V) does not negatively affect circuit operation. The substitute part is rated for higher voltage stress, providing additional safety margin. The circuit will operate within the electrical specifications of both parts.

Q: Is the higher reverse leakage current of the MBR20200CTG a concern?

A: The reverse leakage current of the MBR20200CTG (1 mA @ 200 V) is higher than the STPS16170CT (15 µA @ 170 V). The impact of this difference depends on the specific application. In high-impedance circuits or precision analog applications, this parameter may require circuit-level evaluation. In standard switching applications, the difference is typically negligible.

Q: Are both parts RoHS compliant?

A: Yes. Both the STPS16170CT and MBR20200CTG are ROHS3 Compliant and REACH Unaffected, meeting all current regulatory requirements for electronic components.

Q: What is the availability status of each part?

A: The STPS16170CT is classified as Obsolete, indicating discontinued manufacturing. The MBR20200CTG is classified as Active, indicating current production and long-term availability through authorized distributors.
