Overview
The BYG24DHE3_A/I is a fast avalanche surface-mount rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated junction and operates in the SMA (DO-214AC) package. The device supports a maximum repetitive peak reverse voltage of 200 V and an average forward current of 1.5 A at 65 °C. Key electrical characteristics include a maximum instantaneous forward voltage of 1.25 V at 1.5 A, a peak forward surge current of 30 A, and a maximum reverse recovery time of 140 ns. It is rated for a pulse energy of 20 mJ in avalanche mode and functions within a junction temperature range of -55 to +150 °C.
Feature Summary
- Fast reverse recovery time with soft recovery characteristics
- Avalanche rated capability for non-repetitive pulse energy absorption
- Glass passivated junction for enhanced reliability
- Automotive grade qualification available via specific ordering codes
Applications
- High frequency rectification in switching mode converters
- Freewheeling applications in inverters
- Consumer electronics power supplies
- Computer equipment power circuits
- Telecommunication systems
Procurement Notes
Verify that the component matches the exact Vishay part number BYG24DHE3_A/I. Confirm the SMA (DO-214AC) package type and the 200 V reverse voltage rating. Ensure the supplier provides documentation confirming AEC-Q101 qualification if automotive compliance is required. Cross-reference the datasheet revision date to ensure technical accuracy.
Selection Notes
Select this component for designs requiring fast switching speeds and avalanche ruggedness in a compact surface-mount form factor. The 1.5 A current rating and 200 V blocking voltage define its operational limits. Consider the thermal resistance values when designing heat dissipation strategies for high ambient temperatures or dense PCB layouts.
Part Context
This component belongs to the BYG24 series of fast avalanche SMD rectifiers from Vishay. The series includes variants with different voltage ratings, specifically the BYG24G (400 V) and BYG24J (600 V). All variants share identical physical dimensions and thermal characteristics while differing in their breakdown voltage specifications.
Replacement Considerations
Direct substitutes include other Vishay parts within the same series, such as the BYG24GHE3_A/I or BYG24JHE3_A/I, provided the voltage requirements align. Verify that any replacement maintains the SMA package footprint and meets the 140 ns reverse recovery time specification.
FAQ
Is the BYG24DHE3_A/I qualified for automotive applications?
Yes, the HE3 suffix indicates that the device is AEC-Q101 qualified.
What is the maximum pulse energy the device can handle?
The device is rated for a non-repetitive pulse energy of 20 mJ in avalanche mode.
Does the device feature a standard PN junction?
No, it utilizes a glass passivated junction structure.
