TVS, or Transient Voltage Suppressor, diodes help protect electrical circuits from damage caused by electromagnetic pulses and other forms of electrical overstress (EOS). The MSMCGLCE170A is a TVS diode specifically designed to protect critical aerospace components. This article explores the application field and working principle of the MSMCGLCE170A.

Application Field

The MSMCGLCE170A is designed to protect aerospace electronics and nearby components from electrical overstress (EOS) attacks. It can provide protection up to a peak pulse current of 150 amps. This TVS diode is also designed with a very low capacitance of 0.001 pF to ensure minimal deterioration of signal integrity. The MSMCGLCE170A is RoHS compliant and has a maximum reverse standoff voltage of 135 V.

The MSMCGLCE170A is ideal for a variety of aerospace applications, including cables, radiofrequency, and fiber-optic systems. It can also be used for semiconductor and printed circuit boards used for power surges, circuit protection, and transient suppression.

Working Principle

TVS diodes work by providing a low-impedance path for the surge current to flow through, thereby preventing the voltage across the components from exceeding its rated value. TVS diodes produce a very low impedance when the voltage exceeds its clamping voltage, which is typically one-half to one-third of the device\'s rated voltage. The voltage across the device will then drop to a safe level, thereby protecting the circuit from damage.

The MSMCGLES170A is designed to operate as a bidirectional device, meaning that it can absorb both positive and negative transients. When the voltage difference between its two terminals reaches the TVS diode\'s clamping voltage, the device will conduct a surge current in both directions. The device is designed to absorb the energy of the surge current and convert it to heat, which is then dissipated. By absorbing the surge current, the device prevents it from reaching and damaging other components in the circuit.

Conclusion

The MSMCGLCE170A is a TVS diode specifically designed for space applications. It is designed to protect electronic components from EOS attacks by providing a low-impedance path for the surge current to flow through. The device is also designed with a very low capacitance so as to not degrade signal integrity. The MSMCGLCE170A is rated to provide protection up to a peak pulse current of 150 amps and can absorb both positive and negative transients.
