BAV302-TR3 Equivalent & Substitute Parts

Part Overview

The BAV302-TR3 is a general-purpose fast recovery diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at 150 V DC reverse voltage with 250 mA average rectified current and features a 50 ns reverse recovery time, making it suitable for high-speed switching applications. The device is packaged in MicroMELF format with Tape & Reel (TR) packaging and carries automotive-grade qualification under AEC-Q101. The BAV302-TR3 maintains Active product status and is RoHS3 compliant. Substitute parts are identified when packaging format or supplier delivery method differs while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAV302-TR3 is determined by electrical and mechanical parameter equivalence. The critical parameters that define substitutability are:

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 250 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 100 mA
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 100 nA @ 150 V
• Capacitance @ Vr, F: 1.5 pF @ 0V, 1MHz
• Operating Temperature - Junction (Max): 175°C
• Package / Case: 2-SMD, No Lead (MicroMELF)
• Mounting Type: Surface Mount
• Grade: Automotive
• Qualification: AEC-Q101

The BAV302-TR3 differs from substitute parts only in packaging format and supplier delivery method. The BAV302-TR3 is supplied in Tape & Reel (TR) format, while equivalent parts may be supplied in alternative packaging configurations such as Cut Tape (CT) or Digi-Reel®. All electrical characteristics, thermal performance, compliance certifications, and mechanical dimensions remain identical across the substitution group.

Parameter Comparison

Engineering Selection Recommendations

Both the BAV302-TR3 and BAV302-TR are Active products manufactured by Vishay General Semiconductor - Diodes Division with identical electrical specifications and mechanical dimensions. Selection between these parts is based on packaging and supply chain requirements rather than functional performance.

The BAV302-TR3 is supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly operations. The BAV302-TR is supplied in Cut Tape (CT) and Digi-Reel® formats, suitable for lower-volume applications or alternative handling requirements.

Both parts carry automotive-grade qualification under AEC-Q101 and maintain RoHS3 compliance with REACH Unaffected status. The identical electrical characteristics, thermal ratings, and compliance certifications ensure direct functional interchangeability within the same circuit design.

Selection should be based on:

• Production volume and assembly equipment compatibility
• Supplier inventory availability and lead time requirements
• Packaging format compatibility with existing manufacturing processes
• Cost considerations associated with packaging and delivery methods

Frequently Asked Questions (FAQ)

Q: Can BAV302-TR be used as a direct replacement for BAV302-TR3?

A: Yes. Both parts are electrically and mechanically identical. The only difference is the packaging format: BAV302-TR3 uses Tape & Reel (TR) format, while BAV302-TR uses Cut Tape (CT) and Digi-Reel® formats. Direct substitution is valid when the receiving equipment can accommodate the alternative packaging format.

Q: Are there any electrical performance differences between BAV302-TR3 and BAV302-TR?

A: No. Both parts share identical electrical specifications including 150 V reverse voltage rating, 250 mA average rectified current, 1 V forward voltage at 100 mA, 50 ns reverse recovery time, and all other electrical parameters listed in the parameter comparison table.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both BAV302-TR3 and BAV302-TR carry automotive-grade classification with AEC-Q101 qualification. Both are RoHS3 compliant and REACH Unaffected, meeting automotive industry compliance standards.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for lower-volume applications or manual handling. Digi-Reel® is an alternative reel format. The components themselves are identical.

Q: Can I mix BAV302-TR3 and BAV302-TR in the same production run?

A: Yes, provided your assembly equipment can handle both packaging formats. Since the components are electrically and mechanically identical, mixing packaging formats does not affect circuit performance or reliability.

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

A: Both parts carry MSL 1 (Unlimited), indicating unlimited shelf life without moisture control requirements. No baking or special storage conditions are necessary.

Q: Are these parts suitable for high-speed switching applications?

A: Yes. Both parts feature 50 ns reverse recovery time, classifying them as fast recovery diodes suitable for high-frequency switching circuits and applications requiring rapid diode turn-off characteristics.
