Substitute Part Grouping Explanation

Substitution of the CTLSH3-30M833S TR is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Schottky diode technology
• 30 V maximum DC reverse voltage rating
• 3 A average rectified current capacity
• 450 mV maximum forward voltage at 3 A
• Fast recovery speed characteristic (≤ 500 ns, > 200 mA)
• 1 mA maximum reverse leakage current at 30 V

Mechanical Equivalence Criteria:

• Surface mount packaging configuration
• Operating temperature range of -65°C to 150°C
• Moisture sensitivity level 1 (unlimited)

The B3L30LP-7 from Diodes Incorporated meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The B3L30LP-7 is the designated substitute for the obsolete CTLSH3-30M833S TR based on complete electrical parameter equivalence. The substitute part is manufactured by Diodes Incorporated and maintains active product status, ensuring long-term availability and supply chain continuity.

Compliance Status:

• B3L30LP-7 is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Package Consideration: The substitute uses an 8-PowerUDFN package versus the original 8-PowerVDFN package. Both are surface mount configurations with identical electrical performance. PCB layout and thermal management characteristics may differ due to package geometry; physical footprint verification is required during design transition.

Availability: The B3L30LP-7 has 2224 units in stock as new original inventory, compared to 746 units of the obsolete CTLSH3-30M833S TR.

Frequently Asked Questions (FAQ)

Q: Can the B3L30LP-7 be used as a direct replacement for the CTLSH3-30M833S TR?

A: Yes. The B3L30LP-7 meets all specified electrical parameters: 30 V reverse voltage, 3 A rectified current, 450 mV forward voltage at 3 A, fast recovery speed, and identical reverse leakage characteristics. Both components operate across -65°C to 150°C and have MSL 1 rating.

Q: What is the difference between the 8-PowerVDFN and 8-PowerUDFN packages?

A: Both are 8-lead surface mount power packages designed for Schottky diode applications. The packages differ in physical dimensions and thermal characteristics. PCB layout modifications may be necessary when transitioning between these package types. Consult the respective component datasheets for exact footprint specifications.

Q: Why is the original part listed as obsolete?

A: The CTLSH3-30M833S TR is classified as obsolete by Central Semiconductor Corp. The B3L30LP-7 provides equivalent electrical functionality with active manufacturing status from Diodes Incorporated.

Q: Are there any compliance differences between the two parts?

A: The B3L30LP-7 carries RoHS3 compliance and REACH unaffected status. Both parts are classified under ECCN EAR99 and HTSUS 8541.10.0080. Verify compliance requirements for your specific application and region.

Q: What should be verified before implementing the B3L30LP-7 as a substitute?

A: Verify PCB footprint compatibility with the 8-PowerUDFN package, confirm thermal management requirements are met with the substitute package geometry, and validate that circuit performance is acceptable with the substitute component in your specific application context.
