Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAT74S,115 are classified into two categories based on electrical parameter alignment:

Parametric Equivalent: BAT74S,135 (Nexperia USA Inc.) matches all electrical specifications and package requirements identically to the primary part. This part is a direct functional replacement with identical performance characteristics.

Direct Manufacturer Equivalent: MBD54DWT1G (onsemi) provides equivalent electrical performance with matching diode configuration, voltage ratings, current capacity, and package form factor. The forward voltage specification differs slightly (1 V @ 100 mA versus 800 mV @ 100 mA), remaining within acceptable substitution parameters for Schottky diode arrays.

Similar Substitutes: BAT54DW-7-F (Diodes Incorporated) and MBD330DWT1G (onsemi) are classified as similar substitutes due to deviations in current rating or application focus. BAT54DW-7-F is rated for 100 mA per diode (versus 200 mA), suitable for lower-current applications. MBD330DWT1G is specified as an RF diode with 120 mW power dissipation, designed for RF applications rather than general rectification.

Substitution eligibility is determined by the following key parameters:

• Diode configuration (2 Independent)
• Technology (Schottky)
• Voltage rating (30 V DC reverse minimum)
• Package compatibility (6-TSSOP, SC-88, SOT-363)
• Surface mount mounting type
• Current capacity (200 mA per diode for full equivalence; 100 mA for reduced-current applications)

Parameter Comparison

Engineering Selection Recommendations

BAT74S,135 (Nexperia USA Inc.): This part is the primary parametric equivalent and is recommended as the first choice for direct substitution. All electrical and mechanical specifications are identical to the BAT74S,115. Both parts carry AEC-Q100 automotive qualification and ROHS3 compliance. Inventory availability is 8870 units. No design or layout modifications are required.

MBD54DWT1G (onsemi): This part is suitable for direct substitution in applications where the forward voltage specification of 1 V @ 100 mA is acceptable. The part maintains all other critical parameters including 30 V reverse voltage, 200 mA current rating, 5 ns reverse recovery time, and identical package form factor. The part is Active in product status with 6380 units in stock. Packaging is supplied as Cut Tape (CT) & Digi-Reel® rather than Tape & Reel (TR).

BAT54DW-7-F (Diodes Incorporated): This part is suitable for applications requiring lower current capacity (100 mA per diode versus 200 mA). The part maintains 30 V reverse voltage rating, 5 ns reverse recovery time, and identical package form factor. This substitution is appropriate only when circuit design permits reduced current handling. Inventory availability is 300400 units. Product status is Active.

MBD330DWT1G (onsemi): This part is specified as an RF Schottky diode with 120 mW power dissipation and is designed for RF applications. While it maintains the 30 V voltage rating and identical package form factor, it is not recommended as a general-purpose rectifier substitute for the BAT74S,115 due to its RF-specific design parameters and different application focus.

Frequently Asked Questions (FAQ)

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

A: Yes. BAT74S,135 is a parametric equivalent with identical electrical specifications, package form factor, and automotive qualification. No circuit modifications are required.

Q: What is the difference between BAT74S,115 and MBD54DWT1G?

A: Both parts are 2-independent Schottky diode arrays rated for 30 V and 200 mA per diode in 6-TSSOP packages. The primary difference is forward voltage: BAT74S,115 specifies 800 mV @ 100 mA, while MBD54DWT1G specifies 1 V @ 100 mA. Both are acceptable for most rectification applications. MBD54DWT1G is supplied in Cut Tape & Digi-Reel packaging rather than Tape & Reel.

Q: Can BAT54DW-7-F replace BAT74S,115 in all applications?

A: BAT54DW-7-F is rated for 100 mA per diode, compared to 200 mA for BAT74S,115. This part is suitable only for applications where the circuit current requirement does not exceed 100 mA per diode. Verify circuit current specifications before substitution.

Q: Are all substitute parts automotive-qualified?

A: BAT74S,115, BAT74S,135, and MBD54DWT1G carry AEC-Q100 automotive qualification. BAT54DW-7-F and MBD330DWT1G do not list automotive grade or AEC-Q100 qualification in the provided specifications. For automotive applications, use only AEC-Q100 qualified parts.

Q: What is the package compatibility across all parts?

A: All listed parts use the 6-TSSOP, SC-88, or SOT-363 package designation. These are equivalent package forms suitable for surface mount assembly on identical PCB footprints. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel) does not affect electrical compatibility or PCB mounting.

Q: Is MBD330DWT1G suitable for general rectification applications?

A: MBD330DWT1G is specified as an RF Schottky diode with power dissipation rating of 120 mW. It is designed for RF applications rather than general rectification. Use this part only for RF circuit applications. For general rectification, select BAT74S,135, MBD54DWT1G, or BAT54DW-7-F.

Q: What is the moisture sensitivity level for all substitute parts?

A: All listed parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard component storage practices apply.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.
