CMPD6263 BK PBFREE Schottky Diode Equivalent & Substitute Parts

Part Overview

The CMPD6263 BK PBFREE is a Schottky rectifier diode manufactured by Central Semiconductor Corp, rated for 70V DC reverse voltage with 15mA average rectified current in a surface mount SOT-23 package. This component is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits the use of higher-rated alternatives that maintain electrical compatibility within the application's operational parameters.

Package / Case must be compatible with SOT-23-3 footprint or equivalent surface mount package
Technology must be Schottky
Current - Average Rectified (Io) rating must equal or exceed 15mA
RoHS3 compliance and MSL 1 rating required

Acceptable Variations:

Current - Average Rectified (Io) may exceed 15mA (higher current rating is acceptable)
Operating temperature range may differ provided maximum junction temperature is maintained
Forward voltage (Vf) may vary within Schottky diode specifications
Reverse leakage current may be lower than specified

Substitute parts are grouped into two categories:

Category 1: Single Diode SOT-23 Package - Direct pin-compatible replacements maintaining identical package footprint (BAS70E6327HTSA1, BAS70E6433HTMA1)

Category 2: Diode Array SOT-23 Package - Higher current capacity alternatives in SOT-23 package with diode array configurations (BAS7004E6327HTSA1, BAS7004E6433HTMA1, BAS7005E6327HTSA1, BAS7005E6433HTMA1, BAS7006E6433HTMA1)

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (Same Footprint):

BAS70E6327HTSA1 and BAS70E6433HTMA1 (Infineon Technologies) are single Schottky diodes in SOT-23-3 package with 70V rating and 70mA current capacity. Both parts are ROHS3 compliant with MSL 1 rating. These parts provide higher current handling (70mA vs. 15mA) while maintaining identical package footprint and voltage rating. The primary difference is packaging format: BAS70E6327HTSA1 is supplied in Cut Tape & Digi-Reel format, while BAS70E6433HTMA1 is supplied in Tape & Reel format.

For Applications Requiring Diode Array Configurations in SOT-23-3:

BAS7004E6327HTSA1 and BAS7004E6433HTMA1 (Infineon Technologies) provide 1 Pair Series Connection configuration with 70V rating and 70mA per diode. Both are ROHS3 compliant. BAS7005E6327HTSA1 and BAS7005E6433HTMA1 provide 1 Pair Common Cathode configuration with identical electrical ratings. BAS7006E6433HTMA1 provides 1 Pair Common Anode configuration. Selection depends on circuit topology requirements.

For Higher Current Applications (200mA):

BAS70-04-E3-18 (Vishay General Semiconductor - Diodes Division) is a 1 Pair Series Connection diode array rated for 200mA per diode in SOT-23-3 package with 70V rating and ROHS3 compliance. This part accommodates significantly higher current demands while maintaining the same package footprint.

For Alternative Package Requirements:

BAS7004SH6827XTSA1 (Infineon Technologies) provides 2 Pair Series Connection in SOT-363 (6-VSSOP) package with 70V and 70mA ratings for applications requiring different PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can BAS70E6327HTSA1 or BAS70E6433HTMA1 be used as direct replacements for CMPD6263 BK PBFREE?

A: Yes. Both parts are single Schottky diodes with identical 70V DC reverse voltage rating, SOT-23-3 package footprint, and ROHS3 compliance. The higher current rating (70mA vs. 15mA) is acceptable for applications designed for 15mA operation. Forward voltage characteristics differ slightly (1V @ 15mA vs. 410mV @ 1mA), which must be evaluated for specific circuit requirements.

Q: What is the difference between BAS7004, BAS7005, and BAS7006 series diode arrays?

A: These are diode array configurations in SOT-23-3 package, all rated 70V and 70mA per diode. BAS7004 is 1 Pair Series Connection. BAS7005 is 1 Pair Common Cathode. BAS7006 is 1 Pair Common Anode. Selection depends on circuit topology and pin configuration requirements.

Q: Can diode array parts (BAS7004, BAS7005, BAS7006) replace a single diode application?

A: Diode array parts can replace single diode applications only if the circuit topology permits use of the array configuration. For single diode applications requiring SOT-23-3 footprint, use BAS70E6327HTSA1 or BAS70E6433HTMA1 instead.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape (CT) and Digi-Reel format are supplied in smaller quantities on cut tape. Tape & Reel (TR) format is supplied in continuous reel for high-volume production. Electrical specifications are identical; packaging format selection depends on order quantity and assembly process requirements.

Q: Is BAS70-04-E3-18 suitable for 15mA applications?

A: Yes. BAS70-04-E3-18 is rated for 200mA per diode, which exceeds the 15mA requirement. The 70V DC reverse voltage rating matches the CMPD6263 specification. This part provides higher current capacity margin for applications with potential current growth or design flexibility.

Q: Can SOT-363 or SOT-143 package alternatives be used if PCB layout permits?

A: Yes, if PCB layout and circuit topology accommodate the different package footprint. BAS7004SH6827XTSA1 (SOT-363) and BAS7007E6327HTSA1 or BAS7007E6433HTMA1 (SOT-143) maintain 70V rating and provide higher current capacity. These alternatives require PCB redesign and are suitable only when layout constraints are not limiting factors.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original CMPD6263 BK PBFREE compliance status.

Q: What is the maximum junction temperature difference between CMPD6263 and substitute parts?

A: CMPD6263 BK PBFREE is rated to 150°C maximum junction temperature. BAS70E6327HTSA1, BAS70E6433HTMA1, and BAS70-04-E3-18 are rated to 125°C maximum. BAS7004, BAS7005, BAS7006, BAS7004SH6827XTSA1, BAS7007 series are rated to 150°C maximum. Verify application operating temperature requirements before selection.
