US1K_HF

Single Diodes Overview

The US1K_HF is a single ultra-fast recovery rectifier manufactured by Diodes Incorporated. It features a glass passivated die construction and is housed in the DO-214AC (SMA) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 800V and an average forward rectified current of 1A. Key electrical characteristics include a low reverse leakage current of 5µA at 800V, a forward voltage of 1.7V at 1A, and a fast recovery time of 75ns. It withstands surge currents up to 30A peak and operates within a junction temperature range of -65°C to +150°C.
