Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDBD2060-G is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Voltage - DC Reverse (Vr) (Max): 60 V
• Mounting Type: Surface Mount
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Allowable Variation Parameters:

• Current - Average Rectified (Io): Substitute must meet or exceed 20A per diode requirement
• Voltage - Forward (Vf): Substitute must not exceed 750 mV @ 10 A
• Current - Reverse Leakage @ Vr: Substitute must not exceed 500 µA @ 60 V
• Operating Temperature - Junction: Substitute must cover or exceed -55°C ~ 150°C range
• Technology: Schottky or equivalent barrier technology acceptable

The SBR20A60CTB from Diodes Incorporated qualifies as a substitute based on matching package, voltage rating, configuration, and mounting type. However, the current rating of 10A per diode is lower than the 20A specification of the main part, which represents a functional limitation in applications requiring the full 20A current capacity.

Engineering Selection Recommendations

CDBD2060-G (Primary Selection)

The CDBD2060-G remains the primary component for applications requiring the full 20A per diode current capacity. Both the main part and substitute are Active product status with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compliance. The CDBD2060-G is available in higher inventory (947 pcs) and provides the specified 20A current rating without derating.

SBR20A60CTB (Conditional Substitute)

The SBR20A60CTB qualifies as a substitute only for applications where the current requirement does not exceed 10A per diode. The substitute offers improved forward voltage characteristics (650 mV vs. 750 mV @ 10A) and an extended lower operating temperature limit (-65°C vs. -55°C). Both devices share identical package geometry, voltage rating, configuration, and compliance certifications. The SBR20A60CTB is available in significantly higher inventory (24,299 pcs), supporting supply chain flexibility for lower-current applications.

Selection Criteria:

• Use CDBD2060-G for applications requiring 10A to 20A per diode
• Use SBR20A60CTB only for applications requiring 10A or less per diode
• Both devices are suitable for -55°C to 150°C operating range applications
• Both devices meet ROHS3 and MSL 1 requirements

Frequently Asked Questions (FAQ)

Q: Can the SBR20A60CTB replace the CDBD2060-G in all applications?

A: No. The SBR20A60CTB has a maximum current rating of 10A per diode, while the CDBD2060-G is rated for 20A per diode. The substitute is suitable only for applications where the actual current requirement does not exceed 10A per diode. Applications requiring 10A to 20A per diode must use the CDBD2060-G.

Q: Are the packages physically identical?

A: Yes. Both the CDBD2060-G and SBR20A60CTB use the TO-263-3 D2PAK package with identical pinout and mechanical dimensions (2 Leads + Tab). PCB layout and footprints are interchangeable.

Q: What is the difference between Schottky and Super Barrier technology?

A: Both are barrier diode technologies suitable for fast recovery applications. The Super Barrier technology in the SBR20A60CTB demonstrates lower forward voltage (650 mV vs. 750 mV @ 10A) compared to the Schottky technology in the CDBD2060-G. Both meet the ≤ 500ns fast recovery specification.

Q: Do both parts have the same reverse leakage characteristics?

A: Yes. Both the CDBD2060-G and SBR20A60CTB specify 500 µA reverse leakage current @ 60V, ensuring equivalent leakage performance.

Q: What is the temperature operating range difference?

A: The CDBD2060-G operates from -55°C to 150°C junction temperature. The SBR20A60CTB extends the lower limit to -65°C while maintaining the same 150°C upper limit. For applications within the -55°C to 150°C range, both parts are suitable. For applications below -55°C, only the SBR20A60CTB is qualified.

Q: Are both parts RoHS compliant?

A: Yes. Both the CDBD2060-G and SBR20A60CTB are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.

Q: Which part should I select for new designs?

A: For new designs, select based on actual current requirements. If the application requires up to 10A per diode, either part is acceptable; the SBR20A60CTB offers better forward voltage performance and lower temperature capability. If the application requires 10A to 20A per diode, the CDBD2060-G is mandatory.
