TVS - Diodes are widely used in electronics industry as overvoltage protection devices. The 1.5KE68AHA0G is a high-performance Transient Voltage Suppressor Diode, specifically designed for use in a wide range of overvoltage protection applications.

The 1.5KE68AHA0G consist of two electrically isolated PN junctions fabricated from a single semiconductor substrate. It is designed to provide high surge current capability while maintaining low capacitance. These devices are available in a variety of terminals, shapes, and ratings.

The 1.5KE68AHA0G has an operating breakdown voltage of 16.5 volts, a maximum peak pulse current of 45 amperes, and a reverse leakage current of 10 microamperes at breakdown. The maximum surge current rating is 90 amperes, and it is designed to clamp large overvoltage transients without exceeding its heat dissipation specifications.

The 1.5KE68AHA0G is designed to protect sensitive electronics equipment against overvoltage transients. During normal operation, the diode acts as an open circuit across the protected load. When an overvoltage transient occurs, the diode clamps the voltage at the breakdown voltage. In this way, it reduces the peak voltage across the protected load and provides effective overvoltage protection.

The 1.5KE68AHA0G is widely used in a variety of applications such as DC-DC converters, power switching circuits, military and avionics systems, and medical instrumentation systems. It can also be used in automotive applications, such as in-cab entertainment systems, for protection from electrical transients. It is an ideal choice for noise protection requiring medium voltage and high current ratings.

The 1.5KE68AHA0G works by providing a highly conductive diode that acts as a low-impedance barrier between the protected load and the incoming transient. When the transient voltage exceeds the breakdown voltage of the diode, the diode starts to conduct, offering a low-impedance path which the transient current ‘sees’. This ‘short’ clamps the voltage and dissipates the transient energy in the diode. The diode then recovers, returning to its normal reverse-biased state.

The 1.5KE68AHA0G is a highly reliable, robust and cost-effective overvoltage protection device, providing a low-impedance ‘short’ when subjected to a transient surge. Its wide range of ratings allows it to be used in both high- and low-voltage applications. It is an ideal choice for noise protection, offering a reliable and cost-effective solution for protecting electronic equipment.
