The 1SMA22CAT3G is a robust transient voltage suppression (TVS) diode designed by ON Semiconductor, a leading provider of semiconductor-based solutions. This TVS diode is specifically engineered to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and electrostatic discharge (ESD).

Key Features

• Stand-off Voltage: The device is designed to accommodate a stand-off voltage of 22V, making it suitable for a wide range of applications that require this level of voltage protection.
• Peak Pulse Power: It can handle a peak pulse power dissipation of 400 Watts (@10/1000μs waveform), ensuring reliable protection against high energy transients.
• Fast Response Time: The diode's response time is virtually instantaneous (< 1 picosecond), providing immediate protection against transient voltage spikes.
• Low Leakage Current: It features a low leakage current, minimizing power loss and ensuring efficiency in operation.
• Bi-directional Clamping: The device provides bi-directional clamping, which is beneficial for AC applications or where the polarity of the transient could be either positive or negative.
• Package: Supplied in a compact SMA package, the 1SMA22CAT3G is ideal for space-constrained applications.
