1N6278-E3/73

TVS – Diodes

A transient-voltage-suppression (TVS) diode is a special type of diode that protects sensitive electronic equipment from destructive over-voltage transients—voltage spikes—that occur in the circuit. These transients can be very short in duration but can have very high amplitudes. The 1N6278-E3/73 is a low-capacitance, low-clamping, unidirectional TVS diode that can protect against high-energy surge voltages.

1N6278-E3/73 Application Field and Working Principle

The 1N6278-E3/73 is ideally suited for protection of equipment from voltage surge transients that may occur during electrical power disturbances. It also finds application in protecting high-speed data circuit boards, power system monitoring systems, input/output interface circuits, circuit breakers, surge arrestors, and many other types of devices.

The working principle of the 1N6278-E3/73 is based on the heat conduction of the junction. When a high voltage surge is applied to the diode, the heat generated by the current causes the diode junction to expand and change its electric characteristics. This prevents the surge voltage from reaching the electronic equipment.

The 1N6278-E3/73 is designed with an extra-thin silicon layer to ensure minimal capacitance. This minimizes the circuit loading associated with the diode and reduces the device\'s response time to voltage transients. It does this by utilizing a low-clamping voltage, which allows the diode to protect against surges of up to 100V in a fraction of a microsecond.

The device is well suited for use with three-phase circuits as the circuit can be split into three independent channels for parallel blocking, providing robust protection from surges up to 100V. In addition, the low-clamping voltage ensures that the device will remain safe from any transients that may occur on the system.

The 1N6278-E3/73 is also packaged in a small, compact package, making it ideal for use in high-density applications where space is limited. In addition, the device has an excellent temperature coefficient which ensures its consistency in performance at different temperatures.

In conclusion, the 1N6278-E3/73 is a high-performance, low-clamping device designed to protect sensitive electronic equipment from destructive over-voltage transients. Its small size and low-capacitance make it ideal for high-density applications in power systems, data circuit board protection and other applications. This ensures robust protection from surges of up to 100V with minimal response time.
