1SMA20AT3G

TVS diodes are manufactured to provide electrostatic protection to a range of devices including electronics and communications systems. The 1SMA20AT3G is a transient voltage surge suppressor (TVSS) diode designed to provide overvoltage protection for low power applications. This diode can be used in applications such as consumer electronics, automotive electronics, and non-automotive equipment.

Application Field

The 1SMA20AT3G is a unidirectional Transient Voltage Suppressor (TVS) diode, which is widely used for overvoltage protection of electronics and communications systems. It is designed to protect against voltage transients in electronic circuits against damaging electrostatic discharge. It can be used in applications such as consumer electronics, automotive electronics, and non-automotive equipment.

Working Principle

The 1SMA20AT3G is an overvoltage protection device. It works by clamping the voltage to prevent it from reaching a damaging level. It is a unidirectional TVS that consists of two diodes connected in a series. When a voltage transient exceeding the peak reverse breakdown voltage (VRRM) is applied, the 1SMA20AT3G will conduct the current away from the sensitive electronic components. This protects the components from high voltage transients.

When not in operation, the 1SMA20AT3G will have a low impedance that allows for lower capacitive coupling and faster protection response. This also allows the diode to clamp the voltage quickly to protect your electronic components from overvoltage and electrostatic discharges.

Conclusion

The 1SMA20AT3G is a unidirectional Transient Voltage Suppressor (TVS) diode designed to provide overvoltage protection for low power applications. It is ideal for consumer electronic, automotive electronic, and non-automotive equipment. This diode works by quickly clamping the voltage when it exceeds the peak reverse breakdown voltage, thus preventing it from reaching a damaging level. The low impedance of the 1SMA20AT3G allows for fast protection response and provides reliable transient voltage protection in your electronic components.
