Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAV74,235 are identified based on strict electrical and mechanical parameter compatibility. The substitution logic is organized into two categories:

Parametric Equivalent: Parts that match all critical electrical specifications including diode configuration, reverse voltage rating, forward voltage characteristics, reverse recovery time, reverse leakage current, and junction temperature rating. These parts are functionally interchangeable within the same application context.

Direct Manufacturer Equivalent: Parts that maintain the same diode configuration, reverse voltage rating, forward voltage characteristics, reverse recovery time, reverse leakage current, and package form factor, with allowable variations in average rectified current within the design margin of the application.

The key parameters determining substitution eligibility are:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 50 V
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 100 mA
• Reverse Recovery Time (trr): 4 ns
• Current - Reverse Leakage @ Vr: 100 nA @ 50 V
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount

Parameter Comparison

Engineering Selection Recommendations

BAV74,215 (Nexperia USA Inc.): This part is a parametric equivalent to the BAV74,235, matching all electrical specifications and package requirements. Both parts are manufactured by Nexperia USA Inc., carry Active product status, and maintain ROHS3 compliance. Selection of BAV74,215 is appropriate for direct substitution in applications where the BAV74,235 is specified.

BAV74LT1G (onsemi): This part is a direct manufacturer equivalent with compatible electrical characteristics across all critical parameters. The average rectified current rating is 200 mA per diode, which is 15 mA lower than the BAV74,235 specification of 215 mA. The operating temperature range extends to -55°C, providing broader environmental coverage than the BAV74,235 maximum junction temperature specification. Both parts are ROHS3 compliant and Active in product status. Selection of BAV74LT1G is appropriate for applications where the 200 mA current rating is within design margins and the extended temperature range is beneficial or neutral to system requirements.

Frequently Asked Questions (FAQ)

Q: Can BAV74,215 be used as a direct replacement for BAV74,235?

A: Yes. BAV74,215 is a parametric equivalent with identical electrical specifications, diode configuration, package form factor, and mounting type. Both parts are manufactured by Nexperia USA Inc. and carry Active product status with ROHS3 compliance.

Q: What is the difference between BAV74LT1G and BAV74,235?

A: BAV74LT1G is manufactured by onsemi and differs in average rectified current rating (200 mA versus 215 mA per diode) and operating temperature range (-55°C to 150°C versus 150°C maximum). All other critical electrical parameters, package specifications, and compliance certifications are identical.

Q: Is the 15 mA current difference between BAV74,235 and BAV74LT1G significant?

A: The current difference is a specification parameter that must be evaluated within the context of the application circuit design. If the application circuit operates at or near the 215 mA specification limit of the BAV74,235, the 200 mA rating of BAV74LT1G may not be suitable. If the application operates below 200 mA, BAV74LT1G is compatible.

Q: Are all three parts in the same package?

A: Yes. BAV74,235, BAV74,215, and BAV74LT1G are all housed in the TO-236-3 (SC-59, SOT-23-3) Surface Mount package with identical pinout and land pattern compatibility.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. BAV74,235, BAV74,215, and BAV74LT1G are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the reverse recovery time specification across all parts?

A: All three parts—BAV74,235, BAV74,215, and BAV74LT1G—specify a reverse recovery time (trr) of 4 ns, ensuring consistent switching performance in fast recovery applications.
