Key Featrues
High Power Handling (600W Peak Pulse Power): The TVS diode can handle up to 600W of peak pulse power, making it suitable for applications requiring robust protection against high-energy transient events, such as lightning strikes or power surges. This ensures reliable performance in demanding environments.
Bi-Directional Protection: The diode offers bi-directional protection, safeguarding circuits from voltage spikes in both polarities. This versatility simplifies circuit design and enhances protection in AC or DC systems, improving overall system reliability.
Low Clamping Voltage (486V): With a maximum clamping voltage of 486V at 1.3A, the diode effectively limits transient voltages to safe levels, minimizing the risk of damage to sensitive components. This feature is critical for maintaining the longevity of electronic devices.
Wide Operating Temperature Range (-55°C to 175°C): The diode operates reliably across a broad temperature range, from -55°C to 175°C, making it suitable for use in extreme environments, such as automotive, industrial, or outdoor applications.
Surface Mount Design (DO-214AA, SMB Package): The compact surface-mount package allows for easy integration into modern PCB designs, saving space and enabling high-density layouts. This feature is particularly beneficial for portable or space-constrained devices.
