Introduction to TVS-Diodes

Transient Voltage Suppressors (TVS-diodes) are semiconductor devices used to protect electrical and electronic systems from destructive voltage spikes, or transients. TVS-diodes are designed to offer inrush current handling capability in addition to the transient protection. They come in many different shapes and sizes, making them well-suited for both surface-mount and through-hole applications.

TVS-diodes work by clamping voltage spikes and dissipating them as heat energy. A TVS-diode will resist any voltage surge that is greater than the breakdown voltage of the diode until the energy of the surge is consumed. The device can then be reset and start responding to future voltage spikes.

MSMBJ60AE3/TR Application Field and Working Principle

The MSMBJ60AE3/TR is a small steady state bidirectional TVS diode designed to protect data lines against electrical static discharge (ESD). The device offers improved ESD sound protection over conventional silicon diodes and is suitable for a wide variety of applications including telecom, data communications equipment, and portable consumer electronic devices.

The MSMBJ60AE3/TR is designed to protect up to three data lines at a time. It features an ultra-low capacitance of 0.22 pF typical, making it ideal for high-speed data applications. The device’s excellent clamping capability and low peak pulse current of 6 A (tp 8/20 μs) ensures reliable protection. The MSMBJ60AE3/TR is available in a small SOD-323 surface-mount package.

The working principle of the MSMBJ60AE3/TR is very simple. When an ESD waveform is applied, the TVS diode starts conducting current, immediately clamping the voltage at the breakdown voltage of the device. This limits the ESD voltage to a safe level and prevents the circuit from being damaged. The small capacitance of the device ensures that it does not attenuate or distort high-frequency signals.

Conclusion

TVS-diodes are a versatile type of semiconductor device that can be used to protect a variety of electronics from high-voltage transient surges. The MSMBJ60AE3/TR is an ESD-protection device that provides reliable protection for up to three data lines at a time. Its low capacitance and excellent clamping capability make it well-suited for high-speed applications. The device is available in an easy-to-handle surface-mount package.
