BAV70T-7 Equivalent & Substitute Parts

Part Overview

The BAV70T-7 is a general-purpose diode array featuring a 1 Pair Common Cathode configuration rated for 85 V DC reverse voltage and 75 mA average rectified current per diode. This surface mount component in SOT-523 packaging is designed for small-signal applications requiring fast switching characteristics with a 4 ns reverse recovery time.

The BAV70T-7 is currently discontinued at DiGi Electronics. Equivalent substitute parts are available to maintain design continuity and ensure procurement of functionally identical components with identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the BAV70T-7 are qualified based on electrical and mechanical parameter equivalence. All substitute components must match the following critical parameters:

Diode Configuration: 1 Pair Common Cathode
Voltage - DC Reverse (Vr) (Max): 85 V
Current - Average Rectified (Io) (per Diode): 75 mA (DC)
Voltage - Forward (Vf) (Max) @ If: 1 V @ 50 mA
Reverse Recovery Time (trr): 4 ns
Current - Reverse Leakage @ Vr: 2 µA @ 75 V
Mounting Type: Surface Mount
Package / Case: SOT-523
Technology: Standard

Substitute parts may differ in packaging format (Cut Tape, Tape & Reel), manufacturer identity, product status, and compliance certifications. Operating temperature range may vary within acceptable limits for the application.

Engineering Selection Recommendations

BAV70T-7-F is a direct parametric equivalent manufactured by Diodes Incorporated with identical electrical specifications and SOT-523 packaging. This part is currently in active production status with ROHS3 compliance certification. The BAV70T-7-F is available in Cut Tape and Digi-Reel packaging formats and represents the primary substitute for the discontinued BAV70T-7.

BAV70T-TP is a parametric equivalent manufactured by Micro Commercial Co with identical electrical specifications and SOT-523 packaging. This part is currently in active production status with ROHS3 compliance certification. The BAV70T-TP is available in Tape & Reel packaging format. The operating temperature range is -55°C to 150°C, which differs from the BAV70T-7 specification of -65°C to 150°C. This part is suitable for applications where the lower temperature limit of -55°C is acceptable.

Both substitute parts satisfy the electrical and mechanical requirements for direct replacement in applications originally designed for the BAV70T-7. Selection between substitutes depends on packaging format requirements and operating temperature range specifications for the end application.

Frequently Asked Questions (FAQ)

Q: Can BAV70T-7-F be used as a direct replacement for BAV70T-7?

A: Yes. The BAV70T-7-F matches all critical electrical parameters including reverse voltage rating (85 V), average rectified current (75 mA per diode), forward voltage (1 V @ 50 mA), reverse recovery time (4 ns), and reverse leakage current (2 µA @ 75 V). Both components feature identical 1 Pair Common Cathode configuration in SOT-523 packaging. The primary difference is packaging format and active product status.

Q: What is the difference between BAV70T-7-F and BAV70T-TP?

A: Both parts are parametric equivalents with identical electrical specifications. The differences are: manufacturer (Diodes Incorporated vs. Micro Commercial Co), packaging format (Cut Tape/Digi-Reel vs. Tape & Reel), and operating temperature range (BAV70T-7-F: -65°C to 150°C; BAV70T-TP: -55°C to 150°C). Selection depends on packaging requirements and whether the application requires operation below -55°C.

Q: Are there compliance differences between the main part and substitutes?

A: Yes. The BAV70T-7 is RoHS non-compliant. Both substitute parts (BAV70T-7-F and BAV70T-TP) are ROHS3 compliant. Applications requiring RoHS compliance must use one of the substitute parts.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Cut Tape, Digi-Reel, or Tape & Reel) affects only procurement, handling, and assembly processes. Electrical performance and component specifications remain identical across all packaging formats for the same part number base.

Q: Is the BAV70T-TP suitable for all applications designed for BAV70T-7?

A: The BAV70T-TP is suitable for applications where the operating temperature range of -55°C to 150°C is acceptable. If the application requires operation below -55°C, the BAV70T-7-F with its -65°C to 150°C range is the appropriate substitute.
