The 1SMA24AT3 is a robust transient voltage suppressor (TVS) diode from ON Semiconductor, designed to protect sensitive electronic equipment from voltage spikes and surges. This device is part of the SMA series and is specifically engineered to shield voltage-sensitive components from destruction or degradation. It's an essential component for any application where electronic circuits are at risk of being damaged by overvoltage events, such as lightning strikes, electrostatic discharge (ESD), and other transient power fluctuations.

Key Features

• Stand-off Voltage: 24V - This diode is designed to be in a stand-by state under normal operating conditions and to become active when the voltage exceeds 24 volts, ensuring protection against transient overvoltages.
• Peak Pulse Power Dissipation: 400W - The 1SMA24AT3 can dissipate up to 400 watts of peak pulse power, providing a high degree of protection from surge energy.
• Fast Response Time - The device reacts swiftly to transient overvoltages, ensuring that the sensitive components it is designed to protect are shielded promptly.
• Low Incremental Surge Resistance - The surge resistance of this TVS diode is minimal, enhancing its ability to conduct surge currents without a significant increase in voltage.
• Unidirectional Functionality - The 1SMA24AT3 is designed for unidirectional applications, making it ideal for DC voltage circuits where protection is needed in one direction only.
• Compact SMA Package - The device comes in a small-footprint surface-mount package, making it suitable for high-density PCB designs.

Applications

The 1SMA24AT3 is widely used across various industries and applications, such as:

• Consumer Electronics - Protecting TVs, computers, and other personal electronics from power surges.
• Industrial Systems - Safeguarding sensors, controllers, and factory automation equipment.
• Telecommunications - Ensuring the integrity of communication lines and equipment.
• Automotive Electronics - Defending automotive control systems and electronics against transients.
• Power Supply Circuits - Providing overvoltage protection in power converters and regulators.

The 1SMA24AT3 from ON Semiconductor is an indispensable component for maintaining the reliability and longevity of electronic systems exposed to transient voltage events. With its robust design and high performance, it is the go-to choice for engineers looking to enhance the durability of their electronic designs.
