BAS40-07V,115 Equivalent & Substitute Parts

Part Overview

The BAS40-07V,115 is a Schottky diode array manufactured by Nexperia USA Inc., configured as 2 independent diodes rated for 40 V DC reverse voltage and 120 mA average rectified current per diode. The device is housed in a SOT-563 or SOT-666 surface mount package and is compliant with ROHS3 and REACH standards.

This part carries a product status of "Not For New Designs," indicating it is obsolete or in end-of-life phase. Equivalent and substitute parts are necessary to support existing designs, provide continuity for production runs, and enable migration to active product lines where applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS40-07V,115 is determined by strict equivalence in the following parameters:

Critical Substitution Parameters:

• Diode Configuration: 2 Independent (must match exactly)
• Technology: Schottky (must match exactly)
• Voltage - DC Reverse (Vr) (Max): 40 V (must match or exceed)
• Mounting Type: Surface Mount (must match exactly)
• Package / Case: SOT-563 or SOT-666 (must be compatible)

Allowable Variation:

• Current - Average Rectified (Io) (per Diode): Substitute parts rated at 200 mA are acceptable for applications requiring 120 mA, as higher current ratings provide design margin without functional degradation in circuits designed for 120 mA operation.

The substitute parts BAS40V-7 and BAS40V-TP meet all critical substitution criteria. Both are 2-independent Schottky diode arrays rated for 40 V DC reverse voltage in SOT-563/SOT-666 packages. The increased current rating of 200 mA per diode represents an upward-compatible specification suitable for 120 mA applications.

Parameter Comparison

Engineering Selection Recommendations

BAS40V-7 (Diodes Incorporated) and BAS40V-TP (Micro Commercial Co) are functionally equivalent substitutes for the BAS40-07V,115 in applications requiring 120 mA per diode operation at 40 V DC reverse voltage.

Both substitute parts offer the following advantages:

• Active Product Status: Both BAS40V-7 and BAS40V-TP carry active product status, ensuring long-term availability and manufacturing continuity compared to the obsolete BAS40-07V,115.

• Compliance Certification: Both substitutes maintain ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the original part.

• Current Rating Margin: The 200 mA per diode rating of both substitutes provides 67% additional current capacity relative to the 120 mA requirement of the original design, enabling operation with design margin.

• Package Compatibility: Both substitutes are available in SOT-563 and SOT-666 packages, maintaining mechanical and electrical compatibility with existing PCB layouts designed for the BAS40-07V,115.

• Electrical Characteristics: Forward voltage, reverse voltage rating, and diode configuration are identical across all three parts, ensuring drop-in compatibility in circuit operation.

Selection between BAS40V-7 and BAS40V-TP depends on supplier availability, lead time, and procurement cost. Both parts are electrically and mechanically interchangeable for the specified application.

Frequently Asked Questions (FAQ)

Q: Can BAS40V-7 or BAS40V-TP be used as direct replacements for BAS40-07V,115 in existing designs?

A: Yes. Both BAS40V-7 and BAS40V-TP are direct substitutes. They share identical diode configuration (2 independent), technology (Schottky), reverse voltage rating (40 V), forward voltage characteristics (1 V @ 40 mA), and package options (SOT-563, SOT-666). The higher current rating (200 mA vs. 120 mA) is compatible with 120 mA applications.

Q: What is the difference between SOT-563 and SOT-666 packages?

A: Both SOT-563 and SOT-666 are surface mount packages for dual diode arrays. The BAS40-07V,115 is supplied in SOT-666, while BAS40V-7 and BAS40V-TP are supplied in SOT-563. Both packages are mechanically and electrically compatible for the same circuit function. PCB layout compatibility depends on the footprint design of the original application.

Q: Why do the substitute parts have lower reverse leakage current (200 nA @ 30 V) compared to the original part (10 µA @ 40 V)?

A: The substitute parts exhibit superior reverse leakage characteristics, which is a beneficial improvement. Lower leakage current reduces power dissipation and improves circuit performance. This difference does not affect substitution compatibility.

Q: Are BAS40V-7 and BAS40V-TP interchangeable with each other?

A: Yes. BAS40V-7 and BAS40V-TP are electrically and mechanically identical. Both are 2-independent Schottky diode arrays rated for 40 V, 200 mA per diode, in SOT-563/SOT-666 packages with identical electrical characteristics. Selection between them is based on supplier availability and procurement factors only.

Q: What is the significance of the "Not For New Designs" status of BAS40-07V,115?

A: This status indicates the part is obsolete or in end-of-life phase and is not recommended for new circuit designs. Existing designs using this part should migrate to active alternatives such as BAS40V-7 or BAS40V-TP to ensure long-term supply continuity and manufacturing support.

Q: Can the 200 mA rating of substitute parts be used to increase current capacity in the original design?

A: The substitute parts are rated for 200 mA per diode, but their use in the original design is limited to the 120 mA specification for which the circuit was designed. The higher rating provides design margin and reliability improvement but does not permit circuit redesign to higher current levels without additional analysis of thermal management, PCB trace sizing, and component stress.

Q: Are there any temperature range differences between the original and substitute parts?

A: Yes. The BAS40-07V,115 specifies a maximum junction temperature of 150°C, while BAS40V-7 and BAS40V-TP specify an operating range of -55°C to 125°C. For applications operating within the -55°C to 125°C range, the substitute parts are fully compatible. Applications requiring operation above 125°C require thermal analysis to confirm the original part's higher temperature rating is necessary.
