SMAJ220AE3/TR13 TVS-Diodes

The SMAJ220AE3/TR13 device is a transistor-based TVS-Diode specifically designed to protect sensitive components and circuits from over-voltage and over-current transients. In much the same way as a classical diode, the SMAJ220AE3/TR13 can be used to protect against Electrostatic Discharge (ESD) and Low Impedance Fault (LIF) situations. It is a versatile device that can be used in almost any electronic circuit protection application, from high-speed data lines to power circuits.

Application Fields

The SMAJ220AE3/TR13 is ideal for transient surge protection in automotive, industrial, telecommunications, computer and consumer electronics applications. It is also particularly well suited for protection of digital and electronic devices used in satellites, medical, military and aerospace systems.Its low clamping voltage and fast response time to sudden changes in current make it highly effective in applications such as protecting circuitry from power surge events. The low capacitance of the SMAJ220AE3/TR13 can also be used to greatly reduce signal degradation and overshoot errors in high-speed lines.

Working Principle

The SMAJ220AE3/TR13 works by providing a clamping mechanism that redirects currents and voltages away from sensitive circuitry. When a surge in current or voltage occurs, the TVS diode rapidly switches into a low impedance state. This provides a path for the unwanted current or voltage to be diverted away from the protected circuits, which prevents them from becoming damaged. The device\'s reverse-bias breakdown voltage and surge current ratings determine the types of voltage and current surge that it can handle. The SMAJ220AE3/TR13 device has a peak pulse power of 200 watts and a clamp voltage of 13 volts. This provides effective clamping for transient events with energies in the range of 9 volts to 200 Watts. The SMAJ220AE3/TR13 also has a relatively low junction capacitance of just 3 pF, which minimizes detector drop, reduces system noise, and ensures exceptional signal integrity over a wide range of frequencies up to 1 GHZ. This high frequency operation makes it perfect for applications such as data and communication lines, as well as high-speed power circuits.

Conclusion

The SMAJ220AE3/TR13 is a reliable and versatile device for surge protection in automotive, industrial, telecommunications, computer and consumer electronics applications. Its low clamping voltage, fast response time to sudden changes in current, and low junction capacitance make it highly effective for protecting sensitive circuits from over-voltage and over-current transients. The device\'s peak pulse power rating of 200 watts ensure that it can handle transient events with energies up to 200 watts. The SMAJ220AE3/TR13 is an ideal choice for many applications ranging from high-speed data and communication lines to power circuits.
