BAV70W Equivalent & Substitute Parts

Part Overview

The BAV70W is a diode array from Diodes Incorporated, configured as a 1 Pair Common Cathode general-purpose rectifier. The device is rated for 75 V DC reverse voltage with 300 mA average rectified current per diode and features fast recovery characteristics with a 4 ns reverse recovery time. The BAV70W is packaged in SC-70, SOT-323 surface mount configuration and is qualified to AEC-Q101 automotive standards.

The BAV70W carries an Obsolete product status. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for ongoing production and field support applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAV70W is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Diode configuration must remain 1 Pair Common Cathode
• DC reverse voltage rating must be 75 V or greater
• Forward voltage drop must not exceed 1.25 V @ 150 mA
• Reverse recovery time must be 4 ns
• Operating temperature range must span -55°C to 150°C

Mechanical Compatibility Requirements:

• Package type must be SC-70, SOT-323
• Mounting type must be Surface Mount

Functional Compatibility Requirements:

• Current rating must support the application requirements
• Reverse leakage characteristics must be acceptable for the circuit design

The substitute parts listed below meet these core electrical and mechanical parameters. However, the BAV70W-7-F and BAV70W_R1_00001 operate at reduced current ratings (150 mA per diode versus 300 mA), which represents a functional limitation. These substitutes are suitable only for applications where the circuit current requirements do not exceed 150 mA per diode.

Engineering Selection Recommendations

BAV70W-7-F (Diodes Incorporated)

This part is the manufacturer-recommended substitute from Diodes Incorporated. It maintains active product status and carries ROHS3 compliance with Moisture Sensitivity Level 1 (Unlimited). The BAV70W-7-F is supplied in Tape & Reel packaging with 50,200 units in current inventory. Selection of this part ensures continuity with the original manufacturer and maintains automotive-grade qualification through the BAV70 base product line. The reduced current rating of 150 mA per diode must be evaluated against circuit requirements.

BAV70W_R1_00001 (Panjit International Inc.)

This part is a cross-manufacturer substitute from Panjit International Inc. and carries active product status with ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited). The device is supplied in Tape & Reel packaging with 14,025 units in current inventory. This option provides an alternative source for the BAV70 diode array function. The reduced current rating of 150 mA per diode must be evaluated against circuit requirements.

Both substitute parts demonstrate improved reverse leakage characteristics (2.5 µA @ 75 V versus 50 µA @ 75 V) compared to the obsolete BAV70W, which may provide circuit performance benefits in low-leakage applications.

Frequently Asked Questions (FAQ)

Q: Can BAV70W-7-F or BAV70W_R1_00001 be used as direct replacements for BAV70W?

A: Both parts are electrically and mechanically compatible with BAV70W in terms of package type (SC-70, SOT-323), diode configuration (1 Pair Common Cathode), reverse voltage rating (75 V), forward voltage characteristics (1.25 V @ 150 mA), and reverse recovery time (4 ns). However, the current rating is reduced from 300 mA to 150 mA per diode. Direct substitution is valid only if the circuit application does not require current exceeding 150 mA per diode.

Q: What is the difference between BAV70W-7-F and BAV70W_R1_00001?

A: Both parts share identical electrical specifications and package configuration. The primary differences are manufacturer (Diodes Incorporated versus Panjit International Inc.) and inventory availability. BAV70W-7-F is the manufacturer-recommended substitute with higher current inventory (50,200 units). BAV70W_R1_00001 provides an alternative source option with 14,025 units available.

Q: Why do the substitute parts have lower reverse leakage current?

A: The substitute parts (BAV70W-7-F and BAV70W_R1_00001) specify 2.5 µA @ 75 V reverse leakage compared to 50 µA @ 75 V for the BAV70W. This difference reflects the electrical characteristics of the specific device designs and manufacturing processes. The lower leakage in substitute parts may provide improved performance in circuits sensitive to leakage current.

Q: Are the substitute parts suitable for automotive applications?

A: The BAV70W carries AEC-Q101 automotive qualification. The substitute parts (BAV70W-7-F and BAV70W_R1_00001) are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements. However, automotive qualification status for the substitute parts should be confirmed with the respective manufacturers if AEC-Q101 certification is a design requirement.

Q: What is the significance of the SOT-323 package designation?

A: SOT-323 (also designated SC-70) is a surface mount package for small signal diodes and diode arrays. All three parts (BAV70W, BAV70W-7-F, and BAV70W_R1_00001) use this identical package, ensuring mechanical and electrical compatibility on printed circuit boards without layout modifications.

Q: Can I use these parts interchangeably in production?

A: Interchangeability depends on circuit current requirements. If the application operates at or below 150 mA per diode, both substitute parts are interchangeable with BAV70W from an electrical and mechanical standpoint. If the application requires current above 150 mA per diode, only the BAV70W (or equivalent 300 mA rated devices) is suitable. Qualification and sourcing policies should be reviewed with your procurement and quality departments.
