CMLD6263 TR Equivalent & Substitute Parts

Part Overview

The CMLD6263 TR is a Schottky diode array manufactured by Central Semiconductor Corp, featuring 2 independent diodes rated for 70 V DC reverse voltage and 15 mA average rectified current per diode in a surface mount SOT-563/SOT-666 package. This component is classified as obsolete, making identification of functionally equivalent substitute parts necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CMLD6263 TR is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Diode configuration must remain 2 independent diodes
• Technology must be Schottky
• DC reverse voltage rating must equal or exceed 70 V
• Average rectified current per diode must meet or exceed 15 mA
• Reverse recovery time must be 5 ns or faster
• Operating temperature range must encompass the application requirements

Mechanical Compatibility Requirements:

• Mounting type must be surface mount
• Package must be compatible with SOT-563, SOT-666, or equivalent footprints

The BAS70JW-7-F meets all electrical requirements with enhanced current rating (70 mA vs. 15 mA) and maintains the same reverse voltage (70 V) and recovery time (5 ns). Package compatibility exists through SOT-363 (6-TSSOP, SC-88), which is a standard surface mount alternative to SOT-563/SOT-666.

Parameter Comparison

Engineering Selection Recommendations

The BAS70JW-7-F is a functionally equivalent substitute for the obsolete CMLD6263 TR based on the following engineering criteria:

Electrical Equivalence: The BAS70JW-7-F maintains identical DC reverse voltage (70 V) and reverse recovery time (5 ns) specifications. The current rating of 70 mA per diode exceeds the 15 mA requirement of the CMLD6263 TR, providing design margin. Reverse leakage current is superior at 100 nA versus 200 nA.

Product Status and Availability: The CMLD6263 TR is obsolete with no active manufacturing. The BAS70JW-7-F is actively produced by Diodes Incorporated with 50,400 units in stock, ensuring procurement continuity and long-term availability.

Compliance and Certifications: The BAS70JW-7-F is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification.

Package Consideration: The BAS70JW-7-F uses SOT-363 (6-TSSOP, SC-88) packaging instead of SOT-563/SOT-666. PCB layout modification is required to accommodate the different footprint. Verify pin configuration and spacing compatibility with your application before implementation.

Temperature Range: The BAS70JW-7-F operating temperature range (-55°C ~ 125°C) is narrower than the CMLD6263 TR (-65°C ~ 150°C). Confirm that your application requirements fall within the substitute's specified range.

Frequently Asked Questions (FAQ)

Q: Can the BAS70JW-7-F directly replace the CMLD6263 TR without PCB modification?

A: No. While electrically equivalent, the BAS70JW-7-F uses SOT-363 packaging versus the CMLD6263 TR's SOT-563/SOT-666. PCB footprint redesign is required. Pin configuration must be verified against your schematic.

Q: What is the significance of the higher current rating (70 mA vs. 15 mA) in the BAS70JW-7-F?

A: The higher current rating provides design margin and allows the substitute to operate safely in applications requiring up to 70 mA per diode. This does not affect compatibility with circuits designed for 15 mA operation.

Q: Are there any temperature-related limitations when substituting?

A: Yes. The BAS70JW-7-F maximum junction temperature is 125°C versus 150°C for the CMLD6263 TR. If your application requires operation above 125°C, the substitute is not suitable. Verify your operating temperature requirements fall within -55°C to 125°C.

Q: How do the forward voltage characteristics compare?

A: The specifications are provided at different test conditions (410 mV @ 1 mA for CMLD6263 TR versus 1 V @ 15 mA for BAS70JW-7-F), making direct comparison imprecise. Both are Schottky diodes with typical forward voltage characteristics in the expected range for this technology.

Q: Is the BAS70JW-7-F RoHS compliant?

A: Yes. The BAS70JW-7-F is ROHS3 compliant. The CMLD6263 TR RoHS status is not specified in the available data.

Q: What is the reverse leakage current difference, and does it matter?

A: The BAS70JW-7-F has 100 nA reverse leakage at 50 V versus 200 nA for the CMLD6263 TR. This represents superior leakage performance and is beneficial for low-power applications. The difference is not detrimental to compatibility.

Q: Can I use the BAS70JW-7-F in high-temperature applications?

A: The BAS70JW-7-F is rated to 125°C junction temperature. If your application requires sustained operation above this temperature, alternative substitutes with higher temperature ratings must be evaluated.
