Parameter Comparison

Engineering Selection Recommendations

The BAS40W-05-7-F is the direct parametric equivalent to the BAS40W-05-7-F-79. Both parts are manufactured by Diodes Incorporated and maintain identical electrical specifications, mechanical packaging, and compliance certifications. The primary distinction is product status: BAS40W-05-7-F-79 is classified as obsolete, while BAS40W-05-7-F maintains active status.

For new designs and ongoing production, BAS40W-05-7-F is the appropriate selection due to its active product status and significantly higher inventory availability (17300 Pcs versus 1074 Pcs). Both parts satisfy ROHS3 compliance and REACH requirements, ensuring regulatory alignment across applications.

For legacy systems currently utilizing BAS40W-05-7-F-79, direct substitution with BAS40W-05-7-F is electrically and mechanically valid without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can BAS40W-05-7-F directly replace BAS40W-05-7-F-79 without circuit modification?

A: Yes. BAS40W-05-7-F is a parametric equivalent with identical electrical specifications (40 V reverse voltage, 200 mA average rectified current, 1 V forward voltage at 40 mA, 5 ns reverse recovery time), identical package (SC-70, SOT-323), and identical compliance certifications (ROHS3, MSL 1). No circuit modification is required.

Q: What is the primary reason to transition from BAS40W-05-7-F-79 to BAS40W-05-7-F?

A: BAS40W-05-7-F-79 is classified as obsolete, creating long-term supply risk. BAS40W-05-7-F maintains active product status with substantially higher inventory availability, ensuring component accessibility for production and repair operations.

Q: Are there packaging differences between BAS40W-05-7-F-79 and BAS40W-05-7-F?

A: Both parts use the SC-70, SOT-323 surface mount package. BAS40W-05-7-F-79 is supplied in standard packaging, while BAS40W-05-7-F is available in Cut Tape (CT) and Digi-Reel® formats, providing flexibility in procurement quantities.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both BAS40W-05-7-F-79 and BAS40W-05-7-F are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level), ensuring equivalent environmental and regulatory performance.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution is determined by equivalence in reverse voltage (40 V), average rectified current (200 mA per diode), forward voltage (1 V @ 40 mA), reverse recovery time (5 ns), reverse leakage current (200 nA @ 30 V), and operating temperature range (-55°C to 125°C). All parameters must match exactly.
