1SMA18AT3 Voltage Suppressor Diode by ON Semiconductor

The 1SMA18AT3 is a robust transient voltage suppressor (TVS) diode designed by ON Semiconductor to protect sensitive electronic equipment from voltage spikes and transients induced by lightning and other transient voltage events. This TVS diode is an essential component for ensuring the reliability and longevity of a wide range of electronic systems.

Key Features:

• Peak Pulse Power: The 1SMA18AT3 offers excellent surge capabilities with its 400W peak pulse power dissipation rating for a 10/1000µs waveform. This allows it to effectively clamp transient voltages and protect the circuit.
• Stand-off Voltage: It has a stand-off voltage of 18V, which provides a margin of safety for nominal system voltages, preventing the diode from conducting under normal operation.
• Low Leakage: The device has a low leakage current, ensuring minimal impact on the system's power consumption and performance when the diode is in the stand-by state.
• Fast Response Time: With its fast response time, the 1SMA18AT3 reacts quickly to transient events, providing immediate protection to downstream components.
• Uni-directional: This device is uni-directional, which means it is designed to protect against voltage transients in one polarity, making it ideal for DC applications.

Applications:

The 1SMA18AT3 is versatile and can be used in a variety of applications including:

• Power supply protection
• Industrial systems
• Telecommunication devices
