Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAS40L-HG3-08 are identified through parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain constant:

• Reverse Voltage Rating: 40 V maximum
• Average Rectified Current: 200 mA
• Forward Voltage Drop: 1 V maximum at 40 mA
• Reverse Leakage Current: 10 µA at 40 V
• Junction Capacitance: 2.9 pF at 0 V, 1 MHz
• Package Type: DFN1006-2A (0402 Metric)
• Technology: Schottky diode
• Mounting Configuration: Surface Mount
• Compliance Standards: ROHS3, AEC-Q101 automotive qualification

Parts meeting all these specifications are classified as direct parametric equivalents and may be substituted without circuit redesign or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

Both the BAS40L-HG3-08 and BAS40L-G3-08 are Active product status components manufactured by Vishay General Semiconductor - Diodes Division. Selection between these parts is based on availability and supply chain considerations rather than electrical or mechanical differences.

BAS40L-HG3-08 is suitable for applications requiring automotive-grade Schottky diodes with AEC-Q101 qualification. This part carries full automotive compliance and is appropriate for safety-critical or regulated automotive applications.

BAS40L-G3-08 provides identical electrical performance and mechanical compatibility with equivalent ROHS3 and REACH compliance. This part is suitable for general industrial and consumer applications where automotive qualification is not required.

Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity, indicating robust handling characteristics suitable for standard manufacturing processes. Selection should be based on supply availability, lead time requirements, and specific application compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can BAS40L-G3-08 be used as a direct replacement for BAS40L-HG3-08?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, reverse voltage ratings (40 V), current ratings (200 mA), forward voltage characteristics (1 V @ 40 mA), and package configurations (DFN1006-2A). The parts differ only in manufacturing lot designation and are functionally interchangeable.

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

A: Substitution eligibility is determined by matching: reverse voltage rating (40 V), average rectified current (200 mA), forward voltage drop (1 V @ 40 mA), reverse leakage current (10 µA @ 40 V), and junction capacitance (2.9 pF @ 0V, 1MHz). All substitute parts must meet these specifications exactly.

Q: Are the package dimensions identical between BAS40L-HG3-08 and BAS40L-G3-08?

A: Yes. Both parts use the DFN1006-2A package, which corresponds to the 0402 (1006 Metric) form factor. PCB footprints, solder pad layouts, and mounting procedures are identical.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. The BAS40L-HG3-08 includes AEC-Q101 automotive qualification; the BAS40L-G3-08 does not carry this specific automotive certification.

Q: Can these parts be used in automotive applications?

A: The BAS40L-HG3-08 is qualified to AEC-Q101 automotive standards and is approved for automotive use. The BAS40L-G3-08 lacks automotive qualification and should be evaluated against specific application requirements before use in automotive circuits.

Q: What is the operating temperature range for these diodes?

A: Both parts have a maximum junction operating temperature of 150°C. Specific minimum operating temperature and thermal derating information should be obtained from the manufacturer datasheet.

Q: Are there any differences in reverse leakage characteristics?

A: No. Both parts specify identical reverse leakage current of 10 µA at 40 V reverse bias, ensuring equivalent performance in high-impedance circuit applications.
