BAV70T,115 Equivalent & Substitute Parts

Part Overview

The BAV70T,115 is a general-purpose diode array manufactured by NXP USA Inc., configured as a 1 Pair Common Cathode device rated for 100 V DC reverse voltage and 150 mA average rectified current per diode. The device is packaged in SC-75 (SOT-416) surface mount configuration and is classified as obsolete product status. Due to its obsolete classification, equivalent substitute parts with active product status are available to maintain design continuity and ensure long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAV70T,115 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode (mandatory match)
• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 100 V
• Current - Average Rectified (Io) (per Diode): Equal to or greater than 150 mA
• Reverse Recovery Time (trr): 4 ns (standard small signal specification)
• Technology: Standard (small signal diode array)
• RoHS Status: ROHS3 Compliant
• Mounting Type: Surface Mount

Secondary Considerations:

• Package / Case: Different surface mount packages are acceptable provided PCB layout accommodates the physical dimensions
• Product Status: Active status preferred for long-term availability
• Operating Temperature Range: Minimum junction temperature capability of 150°C

The substitute parts listed below meet or exceed the electrical performance requirements of the BAV70T,115 while offering improved product status and alternative packaging options.

Parameter Comparison

Engineering Selection Recommendations

BAV70M,315 (Nexperia USA Inc., SOT-883)

This substitute provides electrical parameter equivalence to the BAV70T,115 with identical voltage rating (100 V), current rating (150 mA), forward voltage (1.25 V @ 150 mA), and reverse leakage characteristics (500 nA @ 80 V). The BAV70M,315 maintains active product status, ensuring continued availability and supply chain stability. The SOT-883 package is a smaller surface mount option compared to the original SC-75 (SOT-416) footprint, requiring PCB layout modification. This part is recommended for new designs or redesigns where package size reduction is acceptable.

BAV70W,115 (Nexperia USA Inc., SOT-323)

This substitute exceeds the electrical requirements of the BAV70T,115 with identical voltage rating (100 V) and enhanced current rating (175 mA versus 150 mA). Forward voltage and reverse leakage specifications match the original part (1.25 V @ 150 mA and 500 nA @ 80 V respectively). The BAV70W,115 maintains active product status and is manufactured by Nexperia USA Inc. The SOT-323 package is a mid-size surface mount option, offering a balance between the original SC-75 footprint and the smaller SOT-883 alternative. This part is recommended for applications requiring current margin or where SOT-323 package compatibility exists.

BAV70-TP (Micro Commercial Co, SOT-23-3)

This substitute meets the current and reverse recovery time requirements (150 mA and 4 ns) but operates at a reduced voltage rating of 75 V compared to the 100 V specification of the BAV70T,115. The BAV70-TP is suitable only for applications where the circuit design operates at or below 75 V DC reverse voltage. The part maintains active product status and ROHS3 compliance. The SOT-23-3 package is a standard small-outline surface mount option. This part is not recommended as a direct replacement for the BAV70T,115 in circuits designed for 100 V operation.

Frequently Asked Questions (FAQ)

Q: Can the BAV70-TP substitute for the BAV70T,115 in all applications?

A: No. The BAV70-TP operates at a maximum DC reverse voltage of 75 V, while the BAV70T,115 is rated for 100 V. The BAV70-TP is suitable only for circuits designed to operate at 75 V or lower. Use of the BAV70-TP in a 100 V circuit exceeds the device rating and creates reliability risk.

Q: What are the package differences between the substitute parts?

A: The BAV70T,115 uses SC-75 (SOT-416) packaging. The BAV70M,315 uses SC-101 (SOT-883), which is smaller. The BAV70W,115 uses SC-70 (SOT-323), which is intermediate in size. The BAV70-TP uses TO-236-3 (SC-59, SOT-23-3). Each package has different PCB footprint requirements and lead spacing. PCB layout modification is necessary when changing packages.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (BAV70-TP, BAV70M,315, and BAV70W,115) are ROHS3 compliant, matching the compliance status of the BAV70T,115.

Q: Which substitute part is recommended for new designs?

A: The BAV70M,315 or BAV70W,115 are recommended for new designs. Both maintain active product status, ensuring long-term availability. The BAV70M,315 offers the smallest package footprint (SOT-883). The BAV70W,115 offers enhanced current rating (175 mA) with a mid-size package (SOT-323). Selection depends on PCB space constraints and current margin requirements.

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

A: All parts, including the BAV70T,115 and all substitutes, have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.

Q: Do the substitute parts have the same reverse recovery time?

A: Yes. All substitute parts (BAV70-TP, BAV70M,315, and BAV70W,115) have a reverse recovery time (trr) of 4 ns, matching the BAV70T,115 specification for small signal diode array performance.

Q: Can the BAV70W,115 be used in place of the BAV70T,115?

A: Yes, with PCB layout modification. The BAV70W,115 meets or exceeds all electrical requirements of the BAV70T,115 (100 V voltage rating, 175 mA current rating, 1.25 V forward voltage, 500 nA reverse leakage). The SOT-323 package requires different PCB footprint and lead spacing compared to the original SC-75 (SOT-416) package.
