Substitute Part Grouping Explanation

Substitution of the BYG24JHE3_A/I is determined by strict equivalence across the following parameters:

• Voltage Rating: 600 V DC reverse voltage (Vr) maximum
• Current Rating: 1.5 A average rectified current (Io)
• Forward Voltage: 1.25 V maximum at 1.5 A forward current
• Reverse Recovery Time: 140 ns
• Reverse Leakage Current: 1 µA at 600 V
• Package: DO-214AC (SMA) surface mount
• Technology: Avalanche diode classification
• Operating Temperature Range: -55°C to 150°C junction temperature
• Compliance: RoHS3 compliant, REACH unaffected, AEC-Q101 qualified

The substitute part BYG24J-E3/TR maintains identical electrical performance and mechanical compatibility while differing only in packaging configuration (Tape & Reel designation) and inventory availability. Both parts share the same base product number (BYG24) and are manufactured by the same supplier.

Parameter Comparison

Engineering Selection Recommendations

Product Status: Both parts maintain active production status with Vishay General Semiconductor - Diodes Division, ensuring long-term availability and supply chain stability.

Mechanical Compatibility: Both parts are packaged in DO-214AC (SMA) surface mount configuration with identical footprints and soldering requirements. PCB layout and assembly processes require no modification when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can BYG24J-E3/TR be used as a direct replacement for BYG24JHE3_A/I in existing designs?

A: Yes. Both parts are electrically and mechanically identical. All electrical parameters including voltage rating, current rating, forward voltage, and reverse recovery time are equivalent. The DO-214AC (SMA) package footprint is identical, requiring no PCB modifications.

Q: What is the difference between BYG24JHE3_A/I and BYG24J-E3/TR?

A: The parts differ only in packaging designation and inventory availability. Both are Tape & Reel (TR) packaged variants of the same base product (BYG24). The BYG24J-E3/TR designation indicates higher stock availability through Vishay distribution channels.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the BYG24JHE3_A/I and BYG24J-E3/TR carry AEC-Q101 automotive qualification, confirming suitability for automotive-grade applications with appropriate temperature and reliability requirements.

Q: What is the reverse recovery time specification, and why is it important?

A: The reverse recovery time (trr) is 140 ns for both parts. This parameter defines the time required for the diode to switch from forward conduction to reverse blocking state. The fast recovery classification (≤ 500ns) makes these parts suitable for high-frequency switching applications and power conversion circuits.

Q: Do these diodes require any special handling or storage conditions?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements. Standard ESD precautions for surface mount components apply during handling and assembly.

Q: What is the maximum junction temperature operating range?

A: Both parts operate across a junction temperature range of -55°C to 150°C, supporting applications in extreme thermal environments including automotive underhood and industrial control applications.

Q: Are there any RoHS or environmental compliance concerns with these parts?

A: No. Both parts are RoHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components in EU and global markets.
