Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT74S,135 is determined by strict equivalence across the following critical parameters: diode configuration (2 independent), Schottky technology, 30 V maximum reverse voltage rating, package type (6-TSSOP/SC-88/SOT-363), surface mount mounting type, and RoHS3 compliance. Current rating and forward voltage characteristics are secondary selection criteria that determine functional compatibility within the application circuit.

Substitute parts are grouped into two categories:

Parametric Equivalents: Parts that match all critical electrical specifications and package requirements, enabling direct substitution without circuit modification.

Direct Manufacturer Equivalents: Parts from alternative manufacturers that meet identical electrical and mechanical specifications.

Similar Parts: Components with compatible package and core technology but with reduced current ratings or alternative electrical characteristics, suitable for applications with lower current demands.

Parameter Comparison

Engineering Selection Recommendations

BAT74S,115 (Nexperia USA Inc.): This part is a parametric equivalent to the BAT74S,135, offering identical electrical specifications and package configuration. Both parts are manufactured by Nexperia, carry AEC-Q100 automotive qualification, and maintain ROHS3 compliance. Selection between BAT74S,135 and BAT74S,115 is based on inventory availability and supply chain considerations, as no functional difference exists between the two variants.

MBD54DWT1G (onsemi): This direct manufacturer equivalent from onsemi provides identical diode configuration, voltage ratings, current capacity, and package type. The forward voltage specification is 1 V @ 100 mA compared to 800 mV @ 100 mA for the BAT74S,135, representing a 200 mV increase. This part maintains ROHS3 compliance and MSL 1 rating. Selection is appropriate when onsemi supply chain availability is preferred or when the higher forward voltage is acceptable within circuit design margins.

BAT54DW-7-F (Diodes Incorporated): This part shares identical package, voltage rating, and reverse recovery time specifications. However, the current rating is reduced to 100 mA per diode, representing a 50% reduction from the BAT74S,135 specification. Forward voltage is specified at 1 V @ 100 mA. This part is suitable only for applications where the reduced current capacity meets circuit requirements. ROHS3 compliance and MSL 1 rating are maintained.

MBD330DWT1G (onsemi): This part is classified as a similar component with compatible package and Schottky technology. It is specified as an RF diode with 120 mW power dissipation and 30 V peak reverse voltage. Current and forward voltage specifications are not provided in the available data. This part is suitable for RF applications with lower power requirements and is not recommended as a direct substitute for general-purpose rectification applications requiring the full 200 mA current specification.

Frequently Asked Questions (FAQ)

Q: Can BAT74S,115 be used as a direct replacement for BAT74S,135?

A: Yes. BAT74S,115 and BAT74S,135 are parametric equivalents manufactured by Nexperia with identical electrical specifications, package configuration, and automotive qualification. Both parts support 30 V reverse voltage, 200 mA average rectified current per diode, and are housed in 6-TSSOP (SC-88, SOT-363) packages. The parts are interchangeable without circuit modification.

Q: What is the primary difference between BAT74S,135 and MBD54DWT1G?

A: Both parts are functionally equivalent with identical diode configuration, voltage ratings, current capacity, and package type. The primary difference is manufacturer: BAT74S,135 is manufactured by Nexperia, while MBD54DWT1G is manufactured by onsemi. The forward voltage specification differs by 200 mV (800 mV versus 1 V @ 100 mA). Both parts maintain ROHS3 compliance and MSL 1 rating.

Q: Is BAT54DW-7-F suitable as a substitute for BAT74S,135?

A: BAT54DW-7-F is suitable only for applications where the reduced current rating of 100 mA per diode is acceptable. The BAT74S,135 is rated for 200 mA per diode. If the application circuit requires the full 200 mA current capacity, BAT54DW-7-F is not an appropriate substitute. Package, voltage rating, and reverse recovery time are compatible.

Q: When should MBD330DWT1G be considered?

A: MBD330DWT1G is specified as an RF Schottky diode with 120 mW power dissipation and is intended for RF applications. Current and forward voltage specifications are not provided. This part is not recommended as a general-purpose substitute for the BAT74S,135 in standard rectification applications. Selection should be limited to RF circuit applications where the 120 mW power rating and RF characteristics are required.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—BAT74S,115, MBD54DWT1G, BAT54DW-7-F, and MBD330DWT1G—are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity level, matching the BAT74S,135 environmental and regulatory specifications.

Q: What is the significance of the 6-TSSOP package designation?

A: The 6-TSSOP (Thin Shrink Small Outline Package) is also designated as SC-88 or SOT-363. All substitute parts use this identical package configuration, ensuring mechanical and electrical compatibility with printed circuit board layouts designed for the BAT74S,135. No PCB redesign is required when substituting between parts with this package specification.

Q: Can forward voltage differences affect circuit performance?

A: Forward voltage differences between parts can affect circuit performance in precision applications. The BAT74S,135 and BAT74S,115 specify 800 mV @ 100 mA, while MBD54DWT1G and BAT54DW-7-F specify 1 V @ 100 mA. The 200 mV difference may impact voltage drop calculations in low-voltage circuits. Circuit design margins should be verified when substituting between parts with different forward voltage specifications.
