1.5KE16A-HF

The 1.5KE16A-HF is a transient voltage suppressor (TVS), which is part of a bigger family of diodes designed to protect against voltage spikes, typically resulting from lightning strikes or electromagnetic disturbances. The particular type is designed to protect sensitive equipment that works with medium-voltage supply, withstanding up to 16-volts of sustained reverse bias.

The key behind the protection offered by the 1.5KE16A-HF lies in its internal construction, which is composed of two zener diodes connected in series and combined with a PN junction. The latter serves as a regulating diode, with the zener diodes absorbing all the power tipped over during a voltage surge. The PN junction, on the other hand, provides a highly stable breakdown voltage, allowing the 1.5KE16A-HF to work reliably in any situation.

In electrical terms, 1.5KE16A-HF works as a shunt device, conducting current from its anode to its cathode whenever the voltage reaches the breakdown point. This is how the device works to protect the equipment it\'s connected to, as it prevents the voltage to go above the breakdown point. This technology can be applied to power supplies, high-density microcircuits, telecommunications equipment, and many other devices and even some automotive applications.

The 1.5KE16A-HF is also designed to withstand a wide range of transient conditions, including repetitive electromechanical transients, radiations and static discharges. Its construction also allows it to absorb a wide range of current surges, ranging from 1-amps to 800-amps (on a single pulses). This makes them especially useful to protect circuits against hard power surges like those resulting from lightning strikes.

In terms of physical characteristics, the 1.5KE16A-HF is encapsulated in a DO-35 type package, which has a diameter of 2.6 mm and a total length of 5.08 mm. When mounted on a Printed Circuit Board (PCB), it takes up very little space, being one of the smallest operations available in its class.

In conclusion, the 1.5KE16A-HF is an excellent example of the current state of the art of transient voltage suppressors, offering highly reliable protection against voltage spikes and other power surges. Its small size and low power consumption makes it particularly well suited for applications in many different contexts, ranging from telecoms to automotive and many more.
