BAV170VL Equivalent & Substitute Parts

Part Overview

The BAV170VL is a general-purpose diode array manufactured by Nexperia USA Inc., configured as a 1 Pair Common Cathode device in a Surface Mount TO-236-3 (SOT-23-3) package. This component is rated for 85 V DC reverse voltage and 125 mA average rectified current per diode, with a maximum forward voltage of 1.25 V at 150 mA. The part is Active in product status and RoHS3 compliant. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when design specifications permit higher performance ratings.

Substitute Part Grouping Explanation

Substitute parts for the BAV170VL are identified based on electrical and mechanical compatibility within the following criteria:

Primary Substitution Criteria:

• Diode configuration must be 1 Pair Common Cathode
• Package must be TO-236-3, SC-59, or SOT-23-3 (Surface Mount)
• Voltage - DC Reverse (Vr) must be equal to or greater than 85 V
• Current - Average Rectified (Io) must be equal to or greater than 125 mA per diode
• Voltage - Forward (Vf) must be equal to or less than 1.25 V @ 150 mA
• Technology must be Standard
• RoHS3 compliance required

Substitute Parts Identified:

1. BAV70LT1G (onsemi) — Direct manufacturer substitute with enhanced electrical ratings (100 V, 200 mA)
2. BAV170Q-7-F (Diodes Incorporated) — Parametric equivalent with identical electrical specifications and automotive qualification

Both substitute parts meet or exceed the electrical performance requirements of the BAV170VL while maintaining identical package geometry and mounting compatibility.

Engineering Selection Recommendations

BAV170Q-7-F (Diodes Incorporated) — Parametric Equivalent

The BAV170Q-7-F is a parametric equivalent to the BAV170VL with identical electrical specifications (85 V, 125 mA, 1.25 V forward voltage, 3 µs recovery time). This part is AEC-Q101 automotive qualified and operates across an extended temperature range (−65°C to 150°C). Selection of this part is appropriate for applications requiring automotive-grade reliability or extended temperature performance while maintaining exact electrical compatibility with the BAV170VL.

BAV70LT1G (onsemi) — Enhanced Performance Substitute

The BAV70LT1G is a direct manufacturer substitute with enhanced electrical ratings: 100 V reverse voltage (versus 85 V) and 200 mA average rectified current (versus 125 mA). This part is suitable for applications where the BAV170VL is unavailable and where the higher voltage and current ratings do not create design conflicts. The BAV70LT1G operates across a wide temperature range (−55°C to 150°C) and maintains identical package geometry and forward voltage characteristics. The faster reverse recovery time (6 ns versus 3 µs) may provide improved switching performance in high-frequency applications.

Both substitute parts are Active in product status, RoHS3 compliant, and available in high inventory quantities. Selection between them depends on application-specific requirements for voltage rating, current capacity, temperature range, and automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can BAV70LT1G be used as a direct replacement for BAV170VL?

A: Yes. The BAV70LT1G is a direct manufacturer substitute with enhanced electrical ratings. It maintains identical package geometry (SOT-23-3), forward voltage characteristics (1.25 V @ 150 mA), and diode configuration (1 Pair Common Cathode). The higher voltage (100 V) and current (200 mA) ratings are backward compatible with BAV170VL applications rated for 85 V and 125 mA.

Q: What is the difference between BAV170Q-7-F and BAV170VL?

A: The BAV170Q-7-F is a parametric equivalent with identical electrical specifications. The primary differences are: (1) manufacturer (Diodes Incorporated versus Nexperia), (2) AEC-Q101 automotive qualification, and (3) extended operating temperature range (−65°C to 150°C versus 150°C maximum). Electrical performance is identical.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the TO-236-3 (SOT-23-3) package with identical pin configuration for 1 Pair Common Cathode diode arrays. They are mechanically and electrically interchangeable at the PCB level.

Q: Which substitute should be selected for automotive applications?

A: The BAV170Q-7-F is AEC-Q101 qualified and recommended for automotive applications. It provides identical electrical performance to the BAV170VL with automotive-grade reliability certification.

Q: Does the faster reverse recovery time of BAV70LT1G affect circuit performance?

A: The BAV70LT1G has a reverse recovery time of 6 ns compared to 3 µs for the BAV170VL. This faster recovery may improve switching performance in high-frequency rectification or signal conditioning circuits. In low-frequency applications, this difference is not significant.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three parts (BAV170VL, BAV70LT1G, and BAV170Q-7-F) are RoHS3 compliant and REACH unaffected.

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

A: All three parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
