ABS1-HF

Overview

The ABS1-HF is a high-speed switching diode manufactured by Comchip Technology. It features a glass-passivated junction and utilizes the Super Barrier Rectifier (SBR) technology for enhanced performance. The device is designed for general-purpose applications requiring fast recovery times. Key electrical parameters include a maximum repetitive peak reverse voltage of 100V and a maximum average forward rectified current of 1A at 75°C case temperature. The forward voltage drop is typically low, contributing to system efficiency. The component operates within a specified junction temperature range and is housed in a compact DO-204AL (DO-15) axial leaded package suitable for through-hole mounting.

Feature Summary

• Glass-passivated junction provides mechanical integrity and protection against mechanical stresses.
