Key Parameters

Substitute Part Grouping Explanation

Substitution of the STTH1002CBY-TR is determined by the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 200 V
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Equal or greater than 8 A
• Voltage - Forward (Vf) (Max) @ If: Equal or lower than 1.1 V @ 5 A
• Reverse Recovery Time (trr): Equal or lower than 25 ns
• Current - Reverse Leakage @ Vr: Equal or lower than 5 µA @ 200 V
• Operating Temperature - Junction: Must encompass or exceed -40°C to 175°C range

Substitute parts are classified into two categories:

Parametric Equivalent: Identical electrical specifications and automotive qualification. Direct replacement without circuit re-evaluation.

Similar Manufacturer Part: Reduced current rating or modified electrical characteristics. Substitution requires circuit analysis to confirm adequacy for the application.

Parameter Comparison

Engineering Selection Recommendations

STTH1002CB-TR (Parametric Equivalent)

The STTH1002CB-TR is a direct parametric equivalent to the STTH1002CBY-TR. Both devices are manufactured by STMicroelectronics and share identical electrical specifications: 200 V reverse voltage, 8 A average rectified current per diode, 1.1 V forward voltage at 5 A, and 25 ns reverse recovery time. Both devices carry automotive grade qualification under AEC-Q101 and are ROHS3 compliant. The STTH1002CB-TR differs only in the maximum operating temperature specification (175°C maximum versus -40°C to 175°C range). This part is suitable for direct substitution in applications where the operating temperature range does not require the lower -40°C minimum. Inventory availability is significantly higher at 25400 units.

SBR10200CTL-13 (Similar Manufacturer Part - Reduced Current Rating)

The SBR10200CTL-13 is manufactured by Diodes Incorporated and shares the same 200 V reverse voltage rating, TO-252-3 DPAK package, and surface mount configuration. However, the current rating is reduced to 5 A per diode compared to the 8 A specification of the STTH1002CBY-TR. Forward voltage is lower at 940 mV @ 5 A. Reverse leakage current is higher at 100 µA @ 200 V. Operating temperature range is -65°C to 150°C. This part is suitable only for applications where the circuit current requirement does not exceed 5 A per diode and the maximum operating temperature does not exceed 150°C.

SBR6200CTL-13 (Similar Manufacturer Part - Reduced Current Rating)

The SBR6200CTL-13 is manufactured by Diodes Incorporated and shares the same 200 V reverse voltage rating and TO-252-3 DPAK package. The current rating is further reduced to 3 A per diode. Forward voltage is 850 mV @ 3 A. Reverse leakage current is 100 µA @ 200 V. Recovery speed is standard (>500ns) rather than fast recovery. Operating temperature range is -65°C to 175°C. This part is suitable only for applications where the circuit current requirement does not exceed 3 A per diode.

Frequently Asked Questions (FAQ)

Q: Can STTH1002CB-TR be used as a direct replacement for STTH1002CBY-TR?

A: Yes. The STTH1002CB-TR is a parametric equivalent with identical electrical specifications and automotive AEC-Q101 qualification. The only difference is the operating temperature specification (175°C maximum versus -40°C to 175°C range). Substitution is valid for applications operating within the -40°C to 175°C range.

Q: What is the primary limitation of SBR10200CTL-13 as a substitute?

A: The SBR10200CTL-13 has a reduced current rating of 5 A per diode compared to the 8 A specification of the STTH1002CBY-TR. Substitution is valid only when circuit current requirements do not exceed 5 A per diode. Additionally, the maximum operating temperature is limited to 150°C.

Q: What is the primary limitation of SBR6200CTL-13 as a substitute?

A: The SBR6200CTL-13 has a reduced current rating of 3 A per diode and standard recovery speed (>500ns) compared to the fast recovery (≤500ns) of the STTH1002CBY-TR. Substitution is valid only when circuit current requirements do not exceed 3 A per diode and fast recovery characteristics are not required.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use the TO-252-3 DPAK (2 Leads + Tab) SC-63 surface mount package, ensuring mechanical and PCB layout compatibility.

Q: Do the Diodes Incorporated parts carry automotive qualification?

A: Automotive grade and AEC-Q101 qualification are not specified for the SBR10200CTL-13 and SBR6200CTL-13 parts. Both STMicroelectronics parts (STTH1002CBY-TR and STTH1002CB-TR) carry automotive grade and AEC-Q101 qualification.

Q: What is the difference between fast recovery and standard recovery?

A: Fast recovery diodes have reverse recovery time ≤500ns and are specified for applications requiring rapid switching. Standard recovery diodes have reverse recovery time >500ns. The SBR6200CTL-13 uses standard recovery technology, while the STTH1002CBY-TR and SBR10200CTL-13 use fast recovery technology.

Q: Can reverse leakage current differences affect circuit performance?

A: Yes. The STTH1002CBY-TR specifies 5 µA @ 200 V reverse leakage, while the Diodes Incorporated parts specify 100 µA @ 200 V. Higher reverse leakage may affect circuit performance in applications sensitive to leakage current, such as precision analog circuits or high-impedance applications.

Q: Is RoHS3 compliance consistent across all parts?

A: Yes. All four parts (STTH1002CBY-TR, STTH1002CB-TR, SBR10200CTL-13, and SBR6200CTL-13) are ROHS3 compliant.
