Key Parameters

Substitute Part Grouping Explanation

Substitution of the MA3J74500L is determined by equivalence across the following critical electrical and mechanical parameters:

Technology Requirement: Schottky diode technology must be maintained to preserve switching characteristics and forward voltage performance.

Voltage Rating: Substitute parts must support a minimum DC reverse voltage (Vr) rating equal to or exceeding 30 V to ensure safe operation within the original design envelope.

Current Rating: Substitute parts must support a minimum average rectified current (Io) rating equal to or exceeding 30 mA to handle the specified load conditions.

Speed Classification: Substitute parts must operate within the Small Signal ≤ 200mA classification to maintain compatibility with high-frequency switching applications.

Mounting Type: Surface mount technology must be preserved to ensure compatibility with PCB assembly processes and footprint requirements.

Moisture Sensitivity: MSL rating of 1 (Unlimited) is acceptable for substitute parts, indicating no moisture-related handling restrictions.

The BAT854W,115 manufactured by Nexperia USA Inc. satisfies all substitution criteria through superior or equivalent electrical ratings and active product status.

Parameter Comparison

Engineering Selection Recommendations

The BAT854W,115 is a qualified substitute for the MA3J74500L based on the following engineering criteria:

Electrical Compatibility: The BAT854W,115 exceeds all minimum electrical requirements of the MA3J74500L. The 40 V reverse voltage rating provides 33% margin above the 30 V requirement. The 200 mA current rating provides 567% margin above the 30 mA requirement. Forward voltage performance is superior at 550 mV @ 100 mA compared to 1 V @ 30 mA.

Product Status: The BAT854W,115 maintains active product status with 85,162 units in stock, ensuring long-term availability and supply chain continuity. The MA3J74500L is classified as obsolete, making substitution necessary for new procurement.

Compliance and Certifications: The BAT854W,115 is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8541.10.0070) classifications.

Thermal Performance: The BAT854W,115 supports a maximum junction temperature of 150°C, exceeding the MA3J74500L specification of 125°C by 20%.

Package Consideration: The BAT854W,115 is supplied in SOT-323 package format, which differs from the original SMini3-F1 package. PCB layout and footprint modifications are required for implementation.

Frequently Asked Questions (FAQ)

Q: Can the BAT854W,115 directly replace the MA3J74500L without circuit modifications?

A: The BAT854W,115 is electrically compatible with the MA3J74500L across all critical parameters. However, the package format differs (SOT-323 versus SMini3-F1), requiring PCB footprint and layout modifications. Electrical circuit operation remains unchanged.

Q: What is the significance of the higher current rating in the BAT854W,115?

A: The BAT854W,115 is rated for 200 mA average rectified current compared to 30 mA for the MA3J74500L. This higher rating provides design margin and allows the substitute to operate safely in applications requiring up to 200 mA. The original 30 mA requirement is fully satisfied.

Q: Does the improved forward voltage performance of the BAT854W,115 affect circuit operation?

A: The BAT854W,115 exhibits superior forward voltage performance at 550 mV @ 100 mA compared to 1 V @ 30 mA for the MA3J74500L. This improvement reduces power dissipation and heat generation in the diode, benefiting overall circuit efficiency.

Q: Are there moisture sensitivity or handling differences between these parts?

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture-related handling restrictions. Storage and handling procedures are identical.

Q: What compliance certifications apply to the BAT854W,115?

A: The BAT854W,115 is RoHS3 Compliant and REACH Unaffected. Both parts share identical ECCN (EAR99) and HTSUS (8541.10.0070) classifications for export and tariff purposes.

Q: Is the 40 V reverse voltage rating of the BAT854W,115 suitable for 30 V applications?

A: Yes. The 40 V rating exceeds the 30 V requirement, providing design margin and protection against voltage transients. The substitute operates safely within the original 30 V specification.

Q: What is the impact of the different package formats on assembly?

A: The BAT854W,115 uses SOT-323 package format while the MA3J74500L uses SMini3-F1 format. Assembly equipment, pick-and-place programming, and PCB footprints require reconfiguration. Electrical performance is unaffected by this package change.
