Overview
The BYG24G-E3/TR3 is a surface-mount avalanche rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 400 V and an average forward rectified current (Io) of 1.5 A. The device utilizes the DO-214AC (SMA) package and operates within a junction temperature range of -55°C to 150°C. Key electrical characteristics include a maximum forward voltage (Vf) of 1.4 V at 1.5 A, a reverse leakage current of 1 µA at 400 V, and a fast recovery time (trr) of 75 ns.
Feature Summary
- Incorporates avalanche technology for robust operation under transient conditions
- Provides fast recovery performance with low reverse recovery time
- Designed for surface-mount assembly in compact SMA packages
Applications
- High-frequency switching power supplies
- Freewheeling diodes in inductive load circuits
- General-purpose rectification in industrial electronics
Procurement Notes
Verify the specific suffix TR3 indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status aligns with project requirements. Ensure the DO-214AC footprint matches the PCB design. Check for any recent product change notices regarding manufacturing location or material composition updates from the supplier.
Selection Notes
Select this component where high reverse voltage blocking capability is required alongside moderate current handling. The avalanche rating offers protection against voltage spikes compared to standard rectifiers. Consider the thermal management capabilities of the SMA package for the expected operating environment and duty cycle.
Part Context
This part belongs to the BYG20 series of fast recovery avalanche rectifiers. It shares similar electrical specifications with variants like BYG20G-E3/TR3 but may differ in specific testing parameters or packaging configurations. The series is designed for general-purpose applications requiring reliable performance in harsh electrical environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct equivalents such as BYG24G-E3/TR before implementation.
