Product Overview

The CUS520.H3F(T is a silicon epitaxial Schottky barrier diode from Toshiba, optimized for high-speed switching applications. Housed in a USC package (equivalent to SOD-323 and SC-76), it features low reverse current (I_R(2)=5_µA max) and low forward voltage, supporting 30V reverse voltage and 300mA peak forward current. Ideal for high-frequency circuits, power rectification, and signal modulation, its compact design and wide temperature range (-40°C to 100°C) make it suitable for consumer and industrial electronics.

Key Features

• Ultra-Low Reverse Current: Maximum 5µA reverse current at 30V reduces energy loss and improves circuit efficiency.
• Compact Universal Package: USC package compatible with SOD-323/SC-76 enables high-density SMD mounting, saving PCB space.
• High-Speed Switching: Short reverse recovery time suits high-frequency switching applications for fast signal processing.
• Low Forward Voltage Drop: Typical 0.52V at 200mA forward current minimizes conduction loss for energy efficiency.
• Wide Temperature Operation: Operates from -40°C to 100°C, with storage from -55°C to 125°C, ensuring reliability in harsh environments.
