BAS40W-06-7-F-79 Equivalent & Substitute Parts

Part Overview

The BAS40W-06-7-F-79 is a Schottky diode array manufactured by Diodes Incorporated, configured as 1 pair common anode with a maximum reverse voltage of 40 V and average rectified current of 200 mA per diode. The device is housed in a surface mount SC-70, SOT-323 package and is classified as obsolete product status. Due to its obsolete classification, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAS40W-06-7-F-79 are determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Diode configuration: 1 Pair Common Anode
• Technology: Schottky
• Maximum reverse voltage (Vr): 40 V
• Average rectified current (Io): 200 mA per diode
• Reverse recovery time (trr): 5 ns
• Package type: SC-70, SOT-323

Mechanical Parameters (Must Match):

• Surface mount mounting type
• SOT-323 supplier device package

Compliance Parameters (Must Match):

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in forward voltage characteristics, reverse leakage current specifications, or operating temperature ranges do not disqualify a part from substitution eligibility when all primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

BAS40W-06-7-F (Diodes Incorporated)

This part is the direct parametric equivalent to the BAS40W-06-7-F-79, differing only in packaging format (Tape & Reel versus the main part's unspecified packaging) and product status (Active versus Obsolete). All electrical and mechanical specifications are identical. This substitute is recommended as the primary replacement option due to identical specifications and active product status from the original manufacturer. Inventory availability is 3100 pieces.

CMSSH-3AE TR PBFREE (Central Semiconductor Corp)

This part meets all critical electrical and mechanical substitution criteria: 40 V reverse voltage, 200 mA average rectified current, 5 ns reverse recovery time, SC-70 SOT-323 package, and surface mount configuration. The part exhibits an extended operating temperature range (-65°C to 150°C versus -55°C to 125°C) and higher reverse leakage current specification (500 nA @ 25 V versus 200 nA @ 30 V). Both parts maintain ROHS3 compliance and MSL 1 rating. This substitute is suitable for applications where the extended temperature range provides additional design margin. Inventory availability is 6802 pieces.

Frequently Asked Questions (FAQ)

Q: Can BAS40W-06-7-F be used as a direct replacement for BAS40W-06-7-F-79?

A: Yes. The BAS40W-06-7-F is a direct parametric equivalent with identical electrical specifications, diode configuration, voltage ratings, current ratings, and package type. The only differences are packaging format and product status. The substitute is actively manufactured and available.

Q: What are the key differences between the two substitute parts?

A: Both BAS40W-06-7-F and CMSSH-3AE TR PBFREE meet the core substitution criteria. The CMSSH-3AE TR PBFREE offers an extended operating temperature range (-65°C to 150°C) and is manufactured by Central Semiconductor Corp rather than Diodes Incorporated. The reverse leakage current specification differs slightly between the two parts.

Q: Does the forward voltage specification difference in CMSSH-3AE TR PBFREE affect substitution eligibility?

A: No. The CMSSH-3AE TR PBFREE specifies forward voltage at 200 mA, while the main part specifies it at 40 mA. Both specifications fall within the 200 mA maximum average rectified current rating. This difference does not disqualify the part from substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both substitute parts carry ROHS3 compliance certification, matching the main part's compliance status.

Q: What is the significance of the SC-70, SOT-323 package designation?

A: SC-70 and SOT-323 refer to the same surface mount package type. All three parts use this identical package, ensuring mechanical and electrical compatibility on printed circuit boards.

Q: Why is the main part classified as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The BAS40W-06-7-F-79 is no longer actively produced by Diodes Incorporated. The substitute BAS40W-06-7-F remains in active production from the same manufacturer.

Q: Can CMSSH-3AE TR PBFREE be used in applications requiring the -55°C to 125°C temperature range?

A: Yes. The CMSSH-3AE TR PBFREE operating range of -65°C to 150°C encompasses the -55°C to 125°C specification of the main part, providing full compatibility for this temperature range.
