BAS40P2T5G Equivalent & Substitute Parts

Part Overview

The BAS40P2T5G is an active Schottky diode manufactured by onsemi, designed for surface mount applications in the SOD-923 package. This component is a general-purpose Schottky rectifier rated for 40V operation and is widely used in switching power supplies, voltage clamping circuits, and high-frequency rectification applications. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide design flexibility when the primary part is unavailable or when alternative packaging configurations are required for specific board layouts.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS40P2T5G is determined by the following critical parameters:

Mandatory Matching Criteria:

• Technology: Schottky diode
• Voltage Rating: 40V DC reverse maximum
• Base Product Number: BAS40 series
• Product Status: Active
• Compliance: RoHS3 compliant, REACH unaffected

Package Compatibility Consideration: The BAS40P2T5G uses SOD-923 packaging. Substitute parts may employ alternative surface mount packages (such as DFN1006 or 0402 metric equivalents) provided they maintain electrical equivalence and surface mount mounting type. Package selection depends on board layout requirements and PCB footprint availability.

The identified substitute BAS40L-G3-08 shares the same base product number (BAS40), technology (Schottky), voltage rating (40V), and compliance certifications, making it electrically and functionally equivalent despite differing in physical package configuration.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The BAS40P2T5G remains the preferred choice when SOD-923 package footprints are specified in the design. This part is active, fully compliant with RoHS3 and REACH requirements, and carries unlimited moisture sensitivity rating suitable for standard manufacturing environments.

Substitute Part Selection: The BAS40L-G3-08 from Vishay General Semiconductor - Diodes Division is electrically equivalent and suitable for applications where DFN1006 (0402 metric) packaging is compatible with board layout. This substitute maintains identical voltage rating (40V), active product status, and full compliance certifications (RoHS3, REACH unaffected, MSL 1). The substitute provides specified electrical parameters including 200mA average rectified current, 1V forward voltage at 40mA, and 10µA reverse leakage at 40V.

Compliance Verification: Both parts satisfy RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in regulated markets. Both maintain MSL 1 (unlimited) moisture sensitivity, eliminating special handling requirements during assembly.

Frequently Asked Questions (FAQ)

Q: Can BAS40L-G3-08 be used as a direct replacement for BAS40P2T5G?

A: Yes, for applications where the DFN1006 (0402 metric) package footprint is available on the PCB. Both parts share identical voltage rating (40V), Schottky technology, and compliance certifications. Package differences require PCB layout verification.

Q: What is the primary difference between these two parts?

A: The main difference is physical packaging. BAS40P2T5G uses SOD-923 package, while BAS40L-G3-08 uses DFN1006-2A (0402 metric) package. Electrical characteristics remain equivalent for the 40V Schottky diode function.

Q: Are both parts RoHS3 compliant?

A: Yes. Both BAS40P2T5G and BAS40L-G3-08 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.

Q: What does MSL 1 (Unlimited) mean for these parts?

A: MSL 1 indicates unlimited shelf life without special moisture control requirements. These parts do not require dry-pack storage or baking procedures prior to assembly.

Q: How do I determine which substitute is appropriate for my design?

A: Verify your PCB footprint specification. If SOD-923 is required, use BAS40P2T5G. If DFN1006 (0402 metric) footprints are available, BAS40L-G3-08 is suitable. Both maintain 40V voltage rating and Schottky technology.

Q: Are there any temperature rating differences?

A: BAS40L-G3-08 specifies 150°C maximum junction operating temperature. BAS40P2T5G does not provide this specification in available documentation. Verify thermal requirements against your application specifications.

Q: What is the significance of the base product number BAS40?

A: The BAS40 base product number indicates both parts belong to the same Schottky diode family with 40V rating. This commonality ensures functional equivalence across the product line.
