TVS - Diodes

Transient Voltage Suppressors (TVS) - diodes are a kind of semiconductor device. TVS diodes are intended to protect sensitive electronics from damage due to high voltage transients, usually caused by ESD (electrostatic discharge), lightning, and other high-energy electrical events. The MMBZ30VALFHT116 device is a diode array featuring two TVS diodes with a low operating and stand-off voltage.

Application Field

MMBZ30VALFHT116 is a surface-mount device designed to protect I/O interfaces of electronic equipment from ESD and high-energy surge events. It can be used in a wide array of applications in the automotive, telecom, industrial, and military sectors. It is suitable for protection against ESD, lightning-induced transients and other high-energy electrical events, offering reliable protection with minimal false tripping rate due to its low clamping voltage.

Working Principle

The MMBZ30VALFHT116 provides dual protection in a single device, as it has two silicon avalanche diodes arranged in a back-to-back configuration. In normal mode, the diode structure behaves as an open switch. When a high voltage transient is applied to either the anode or the cathode, the avalanche effect causes the voltage across the diode to drop and clamp the voltage by allowing a surge current while limiting the voltage across the protected device. Once the surge event has passed, the diode returns to its open-circuit state.

The device is designed to respond quickly to high-voltage transients and clamp the voltage across the protected device before it has time to damage it. The MMBZ30VALFHT116 has a fast response time, low operating voltage, and low clamping voltage, which makes it suitable for a wide variety of applications where low clamping voltage is required.

Conclusion

In conclusion, the MMBZ30VALFHT116 is a TVS diode array designed for protection against ESD, lightning-induced transients and other high-energy electrical events. It is suitable for a wide range of applications in the automotive, telecom, industrial, and military sectors due to its low clamping voltage, fast response time, and low operating voltage.
