ES1D-E3/61T – VISHAY

Overview

The Vishay ES1D-E3/61T is a high-performance 1A, 200V standard recovery rectifier diode, crucial for efficient power rectification in compact designs. Its primary advantage lies in its robust 1A current handling capability within a standard SMA (DO-214AC) package, offering a significant power density improvement over older through-hole equivalents. Engineers must carefully consider the trade-off between its fast switching characteristics (25ns reverse recovery time) and potential EMI generation in sensitive analog circuits, often necessitating careful layout and filtering to mitigate unwanted noise.
