SK106-TP Equivalent & Substitute Parts

Part Overview

The SK106-TP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 60V DC reverse voltage and 10A average rectified current in a DO-214AB (HSMC) surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The SK106-TP serves in applications requiring fast recovery Schottky diode performance with moderate to high current handling capability.

Substitute Part Grouping Explanation

Substitution of the SK106-TP is determined by the following critical parameters:

Voltage Rating: All substitute parts must maintain a minimum DC reverse voltage rating of 60V to ensure equivalent reverse bias protection.

Current Rating: The SK106-TP is rated for 10A average rectified current. Substitute parts with lower current ratings (3A or 5A) are listed as partial substitutes suitable only for applications with reduced current requirements. Substitute parts with equal or higher current ratings provide direct functional equivalence.

Package Type: The SK106-TP uses DO-214AB (SMC) surface mount packaging. Substitute parts must use compatible surface mount packages (DO-214AB, SMC, or SMA) to ensure PCB layout compatibility.

Technology: All listed substitutes employ Schottky diode technology with fast recovery characteristics (≤ 500ns), matching the SK106-TP's switching performance profile.

Forward Voltage: The SK106-TP specifies 850 mV maximum forward voltage at 10A. Substitute parts with lower forward voltage ratings indicate improved efficiency characteristics.

Compliance: RoHS3 compliance is preferred for new designs; however, RoHS non-compliant alternatives are listed where current availability and performance parameters align.

Engineering Selection Recommendations

For Direct Functional Replacement (10A Current Requirement):

No active substitute part with 10A current rating is available in the provided list. Applications requiring the full 10A capacity of the SK106-TP must either source remaining SK106-TP inventory or redesign circuits to operate at reduced current levels using available substitutes.

For Reduced Current Applications (5A Maximum):

B560C-13-F and CDBC560-G are suitable for applications requiring up to 5A. Both parts maintain 60V reverse voltage rating and DO-214AB packaging compatibility. B560C-13-F offers ROHS3 compliance and higher maximum junction temperature (150°C). CDBC560-G provides equivalent performance with ROHS3 compliance and standard junction temperature rating (125°C).

For Further Reduced Current Applications (3A Maximum):

Multiple active alternatives exist for 3A applications: B360-13-F, CDBC360-G, HSM360J/TR13, MBRS360T3G, SK36/TR13, SS36, and STPS3L60S. Selection among these options depends on compliance requirements and thermal performance needs.

Compliance Considerations:

ROHS3-compliant alternatives include B360-13-F, B560C-13-F, CDBC360-G, CDBC560-G, MBRS360T3G, SS36, and STPS3L60S. These parts are preferred for new designs subject to RoHS regulations. RoHS non-compliant alternatives (HSM360J/TR13, HSM560J/TR13, SK36/TR13) remain available for legacy system support and applications where RoHS compliance is not required.

Thermal Performance:

HSM360J/TR13, HSM560J/TR13, and MBRS360T3G offer maximum junction temperatures of 175°C, providing superior thermal margin compared to the SK106-TP (125°C). These parts are suitable for high-temperature operating environments.

Package Compatibility:

SS36 uses DO-214AC (SMA) packaging, which differs from the SK106-TP's DO-214AB (SMC) package. PCB layout modifications are required for SS36 substitution. All other listed alternatives use compatible DO-214AB or SMC packaging.

Frequently Asked Questions (FAQ)

Q: Can I use a 5A-rated diode in place of the 10A SK106-TP?

A: A 5A-rated diode can be used only in applications where the actual circuit current does not exceed 5A. The SK106-TP's 10A rating indicates the maximum safe continuous current. Using a lower-rated part in a 10A circuit will cause excessive heat generation and component failure. Circuit redesign or current limiting is required to safely use 5A substitutes.

Q: What is the difference between DO-214AB and SMA packages?

A: DO-214AB (SMC) and DO-214AC (SMA) are different surface mount package outlines. While both are surface mount Schottky diodes, they have different physical dimensions and PCB pad layouts. SS36 uses SMA packaging and requires different PCB footprint design compared to the SK106-TP's DO-214AB package. Direct PCB substitution without layout modification is not possible.

Q: Are RoHS non-compliant parts acceptable for new designs?

A: RoHS non-compliant parts (HSM360J/TR13, HSM560J/TR13, SK36/TR13) are acceptable only for applications not subject to RoHS regulations or for legacy system maintenance. New product designs intended for sale in regulated markets must use ROHS3-compliant alternatives.

Q: How does forward voltage affect circuit performance?

A: Forward voltage (Vf) determines the voltage drop across the diode during conduction. Lower forward voltage reduces power dissipation and heat generation. The SK106-TP specifies 850 mV at 10A, while most 3A and 5A substitutes specify 700 mV or lower at their respective current ratings. In circuits operating at reduced current levels, lower forward voltage substitutes improve efficiency.

Q: Can I use multiple lower-rated diodes in parallel to achieve 10A capacity?

A: Parallel connection of Schottky diodes requires careful thermal and current-sharing design. This approach is not addressed in the provided substitute parts list and falls outside the scope of direct component substitution. Consult application-specific design guidelines for parallel diode configurations.

Q: What is the significance of reverse leakage current specifications?

A: Reverse leakage current indicates the small current flowing through the diode when reverse-biased. The SK106-TP specifies 1 mA at 60V, which is higher than most substitutes (typically 55 µA to 500 µA). Lower reverse leakage reduces standby power consumption and heat generation in reverse-biased conditions. This parameter becomes significant in low-power or battery-powered applications.

Q: Are all listed substitutes pin-compatible with the SK106-TP?

A: All listed substitutes use Schottky diode technology with identical functional pin configurations (anode and cathode). However, physical package dimensions differ between DO-214AB (SMC) and DO-214AC (SMA) variants. Verify PCB footprint compatibility before substitution. Parts using identical DO-214AB packaging (B360-13-F, B560C-13-F, CDBC360-G, CDBC560-G, HSM360J/TR13, HSM560J/TR13, MBRS360T3G, SK36/TR13, STPS3L60S) are directly pin-compatible.
