STTH602CBY-TR Equivalent & Substitute Parts

Part Overview

The STTH602CBY-TR is a general-purpose diode array manufactured by STMicroelectronics, configured as 1 pair common cathode with 200 V reverse voltage rating and 3 A average rectified current per diode. The device is housed in a Surface Mount TO-252-3 DPAK package and is classified as Active product status with AEC-Q101 automotive qualification. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility within specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STTH602CBY-TR is permissible when the following criteria are met:

Critical Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 200 V (minimum requirement)
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• Current - Average Rectified (Io) (per Diode): Equal to or greater than 3 A

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: May vary within design tolerance
• Reverse Recovery Time (trr): May vary within design tolerance
• Current - Reverse Leakage @ Vr: May vary within design tolerance
• Operating Temperature - Junction: May extend beyond specified range
• Technology: May differ (Standard, Super Barrier, etc.)

All substitute parts listed maintain identical package geometry, pin configuration, and surface mount compatibility. Electrical performance remains within acceptable operating margins for applications designed for the STTH602CBY-TR.

Parameter Comparison

Engineering Selection Recommendations

STTH602CBY-TR (Primary Reference) All substitute parts are qualified alternatives. Selection is based on availability and design requirements within the specified parameter envelope.

RF601BM2DTL (Rohm Semiconductor) This substitute provides higher current capacity (6 A versus 3 A) with improved forward voltage characteristics (930 mV @ 3 A). Fast recovery speed classification is maintained. Operating temperature maximum is limited to 150°C. Product status is Active with ROHS3 compliance. This part is suitable for applications requiring higher current margin or lower forward voltage dissipation.

SBR10200CTL-13 (Diodes Incorporated) This substitute provides 5 A current capacity with Super Barrier technology. Forward voltage is 940 mV @ 5 A. Fast recovery speed classification is maintained. Operating temperature range is -65°C ~ 150°C. Product status is Active with ROHS3 compliance. This part is suitable for applications requiring extended low-temperature operation.

SBR6200CTL-13 (Diodes Incorporated) This substitute matches the 3 A current rating with Super Barrier technology and improved forward voltage (850 mV @ 3 A). Speed classification is Standard Recovery (>500ns). Operating temperature range extends to 175°C, matching the primary part. Product status is Active with ROHS3 compliance. This part is suitable for applications where lower forward voltage dissipation is prioritized and recovery speed is not critical.

All substitute parts maintain identical package geometry (TO-252-3 DPAK), surface mount compatibility, and 200 V reverse voltage rating. All parts are ROHS3 compliant and Active product status.

Frequently Asked Questions (FAQ)

Q: Can RF601BM2DTL replace STTH602CBY-TR in all applications? A: RF601BM2DTL is mechanically and electrically compatible as a substitute. The higher current rating (6 A versus 3 A) provides additional margin. However, the maximum operating temperature is limited to 150°C compared to 175°C for the STTH602CBY-TR. Verify application temperature requirements before substitution.

Q: What is the primary difference between SBR10200CTL-13 and SBR6200CTL-13? A: SBR10200CTL-13 provides 5 A current capacity with operating temperature range of -65°C ~ 150°C. SBR6200CTL-13 provides 3 A current capacity with operating temperature range of -65°C ~ 175°C. Both use Super Barrier technology. Select based on current requirements and operating temperature envelope.

Q: Are all substitute parts in the same package? A: Yes. All parts listed use TO-252-3 DPAK (2 Leads + Tab), SC-63 package. Surface mount footprint and pin configuration are identical, enabling direct board-level substitution without layout modification.

Q: What does "1 Pair Common Cathode" configuration mean? A: This indicates the diode array contains two diodes with a shared cathode terminal. All substitute parts maintain this identical configuration, ensuring functional equivalence in circuit applications.

Q: Can SBR6200CTL-13 be used where fast recovery speed is required? A: SBR6200CTL-13 is classified as Standard Recovery (>500ns), whereas STTH602CBY-TR is Fast Recovery (≤500ns). Applications requiring fast recovery switching characteristics should not use SBR6200CTL-13 as a substitute.

Q: Are all substitute parts RoHS compliant? A: Yes. All parts listed are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.

Q: What is the significance of reverse recovery time (trr)? A: Reverse recovery time affects switching speed and electromagnetic interference characteristics. STTH602CBY-TR specifies 30 ns, RF601BM2DTL specifies 25 ns. Lower values indicate faster switching transitions. SBR10200CTL-13 and SBR6200CTL-13 do not specify this parameter.

Q: Can these parts be used in automotive applications? A: STTH602CBY-TR carries AEC-Q101 automotive qualification. Substitute parts do not list automotive qualification in the provided specifications. Verify automotive compliance requirements with the component manufacturer before use in automotive applications.
