TVS - Diodes

Transient Voltage Suppression Diodes, or TVS Diodes, are used in circuit protection solutions. They provide a fast and reliable solution to the ever-increasing demand for short-term protection from power surge or overvoltage transients. The MASMCG85A is a specialized TVS known as a “bidirectional overvoltage protection diode”.

MASMCG85A Application Fields

The MASMCG85A is well suited for a variety of application domains including automotive electronics, telecommunication systems, power electronics, data processing equipment, and consumer electronics. It has been designed specifically for use as overvoltage protection from either positive or negative voltage transients. The capability of the MASMCG85A to safely dissipate multiple transient events makes it a more reliable and durable alternative to other similar protection solutions.

MASMCG85A Working Principle

When the voltage transient exceeds the breakover voltage, the MASMCG85A quickly absorbs the voltage by directing it through the diode junction. The diode then rapidly conducts the current to ground, clamping the transient energy within a safe operating range. As the voltage drops back to a safe level, the diode “opens” again and normal circuit functioning is restored.The MASMCG85A has a fast response time, typically a few nanoseconds. This along with its low capacitance make it a reliable protector against fast glitch surges on data and communications lines. The device also benefits from its low leakage current, which acts to reduce self-discharge time and preserve the operation of an electronic circuit.

Conclusion

The MASMCG85A is a specialized TVS diode that is well suited to a variety of applications which require reliable protection from transient overvoltage events. With its fast response time, low capacitance, and low leakage current, the device is an ideal choice for protecting both data and communication lines. Ultimately, the MASMCG85A is a reliable and durable solution for protecting sensitive electronic circuitry from power surge or overvoltage transients.
