SBL1630CT Equivalent & Substitute Parts

Part Overview

The SBL1630CT is a Schottky diode array manufactured by Diodes Incorporated, configured as a 1 Pair Common Cathode device rated for 30 V DC reverse voltage and 16 A average rectified current per diode. The component is packaged in TO-220-3 through-hole configuration and is currently classified as obsolete. Due to its obsolete status, identification of equivalent and substitute parts is necessary for ongoing design support, maintenance, and production continuity. Alternative components must satisfy the electrical and mechanical requirements of the original specification while accounting for available product status and compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the SBL1630CT are classified into two categories based on substitution criteria:

Direct Manufacturer Substitute: Parts that differ in one or more key electrical parameters but maintain the same diode configuration and mounting type. The SBR20U40CT represents a direct substitute with modified voltage and current ratings.

Parametric Equivalents: Parts that maintain identical electrical specifications (30 V, 16 A, Schottky technology, 1 Pair Common Cathode configuration) but differ in package form factor or operating temperature range. These include TO-220-3 and TO-247-3 package variants from Taiwan Semiconductor Corporation.

Substitution logic is determined by the following key parameters:

Diode Configuration (1 Pair Common Cathode)
Technology (Schottky or Super Barrier)
Voltage - DC Reverse (Vr) (Max)
Current - Average Rectified (Io) (per Diode)
Mounting Type (Through Hole)
Package / Case compatibility

Engineering Selection Recommendations

For Direct Replacement (Same Package, TO-220-3):

The SR1630 C0G and SR1630HC0G from Taiwan Semiconductor Corporation provide parametric equivalence to the SBL1630CT with identical electrical specifications. Both maintain 30 V reverse voltage, 16 A current rating, and Schottky technology. The SR1630HC0G variant includes AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade components. Both parts are currently in active product status, ensuring long-term availability and supply chain stability.

The SBR20U40CT from Diodes Incorporated is a direct manufacturer substitute with modified electrical parameters: 40 V reverse voltage and 10 A current rating. This part is suitable only for applications where the reduced current rating (10 A versus 16 A) and elevated voltage rating (40 V versus 30 V) are acceptable. The SBR20U40CT is active and available in higher inventory quantities.

For Alternative Package Form (TO-247-3):

The SR1630PT C0G and SR1630PTHC0G provide identical electrical specifications in a TO-247-3 package. These parts are suitable for applications where the larger TO-247-3 form factor is preferred or required for thermal management. The SR1630PTHC0G includes AEC-Q101 automotive qualification. Both variants are currently active and available.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. The Taiwan Semiconductor Corporation parts are REACH Unaffected, while the Diodes Incorporated SBR20U40CT is REACH Affected. Selection should account for supply chain compliance requirements.

Temperature Range Consideration:

The SBL1630CT operates across -65°C to 150°C. Taiwan Semiconductor Corporation parametric equivalents operate across -55°C to 125°C, representing a narrower temperature range. Applications requiring the full -65°C to 150°C range must use the SBR20U40CT or confirm that the reduced range is acceptable for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the SBR20U40CT directly replace the SBL1630CT?

A: The SBR20U40CT is a direct manufacturer substitute but with modified electrical specifications. It provides 40 V reverse voltage (versus 30 V) and 10 A current rating (versus 16 A). Substitution is valid only if the application can operate within these modified parameters. The reduced current rating may limit performance in high-current applications.

Q: What is the difference between SR1630 C0G and SR1630HC0G?

A: Both parts are parametric equivalents with identical electrical specifications. The SR1630HC0G includes AEC-Q101 automotive qualification and is designated for automotive applications. Selection depends on whether automotive-grade certification is required.

Q: Can I use a TO-247-3 package part (SR1630PT C0G) in place of the TO-220-3 package SBL1630CT?

A: The TO-247-3 package is physically larger than TO-220-3 and has different pin spacing and mounting hole locations. Direct mechanical substitution is not possible without PCB redesign. However, the electrical specifications are identical, making it suitable for new designs or applications where PCB modification is feasible.

Q: Are all substitute parts RoHS compliant?

A: Yes, all substitute parts listed are ROHS3 compliant. However, the SBR20U40CT is REACH Affected, while Taiwan Semiconductor Corporation parts are REACH Unaffected. Verify compliance requirements for your specific supply chain and regulatory jurisdiction.

Q: What is the operating temperature range difference between the SBL1630CT and Taiwan Semiconductor Corporation equivalents?

A: The SBL1630CT operates from -65°C to 150°C. Taiwan Semiconductor Corporation parts (SR1630 series) operate from -55°C to 125°C. The SBL1630CT provides a wider temperature range. If your application requires operation below -55°C or above 125°C, the SBL1630CT or SBR20U40CT must be used.

Q: Which substitute part has the best availability?

A: The SBR20U40CT has the highest inventory (4074 Pcs), followed by SR1630PT C0G (985 Pcs) and SR1630PTHC0G (917 Pcs). The SR1630 C0G and SR1630HC0G have lower inventory levels (794 Pcs and 738 Pcs respectively). Inventory levels should be verified with suppliers for current availability.

Q: Can I use the SBR20U40CT in a 30 V application?

A: Yes, the SBR20U40CT is rated for 40 V reverse voltage, which exceeds the 30 V requirement. However, the current rating is reduced to 10 A. If your application requires 16 A at 30 V, the SBR20U40CT is not suitable. For 30 V applications requiring 16 A, use the Taiwan Semiconductor Corporation SR1630 series parts.

Q: What is the forward voltage difference between SBL1630CT and SBR20U40CT?

A: The SBL1630CT has a forward voltage of 550 mV @ 8 A. The SBR20U40CT has a forward voltage of 470 mV @ 10 A. The SBR20U40CT exhibits lower forward voltage, which may result in reduced power dissipation in the substitute part. This difference is due to the Super Barrier technology used in the SBR20U40CT versus the standard Schottky technology in the SBL1630CT.
