Procurement Notes
Verify that the ordering suffix matches the required packaging quantity and delivery mode. Confirm RoHS compliance status and check if automotive qualification via AEC-Q101 is necessary for the specific application environment. Ensure the base part number corresponds to the correct voltage rating variant within the series.
Selection Notes
Select this component when a fast recovery rectifier with avalanche capability is required in a surface-mount SMA package. Consider the 800 V reverse voltage rating and 1.5 A continuous current capacity against circuit demands. Evaluate thermal resistance requirements based on the expected ambient temperature and mounting conditions.
Part Context
This component belongs to the BYG21 series of Fast Avalanche SMD Rectifiers from Vishay. The series includes variants with different voltage ratings, such as the BYG21M rated at 1000 V. These devices are designed for general-purpose rectification in compact electronic designs requiring high-speed switching performance.
