1V5KE39CA

TVS (transient voltage suppressor) diodes are devices designed to protect sensitive electronics from voltage spikes and surges. The 1V5KE39CA is one example of such a device. It is a bi-directional, general purpose transient voltage suppressor designed specifically to protect sensitive electronics and components from damage caused by electrostatic discharges, voltage spikes, and overvoltage transients.

The 1V5KE39CA has a stand-off voltage of 14V, with a peak pulse power rating of 150 W and an operating junction temperature of 125°C. It is constructed from a combination of silicon and merged PN junction technology, and offers reverse stand-off voltage and surge peak power protection up to 1500 W. It also offers superior clamping capability, and low leakage current.

The working principle behind the 1V5KE39CA is that when a transient appears across the diode, the integrated PN junction structures act to re-distribute the transient energy within the device. This energy is then ultimately dissipated as heat in the silicon die. This happens at a rate that is much faster than a standard diode can respond, creating a protective barrier that safeguards against voltage overshoots and power surges.

The 1V5KE39CA is primarily used to protect automotive electronics and components from voltage transients, such as heavy-duty automotive equipment, vehicle electrical systems, and telematics. It is also used in consumer electronics and IT hardware, to protect components from damage caused by static electricity during repairs and service. It is also found in many medical equipments, such as medical imaging, patient monitors, and laboratory analyzers.

In conclusion, the 1V5KE39CA is a bi-directional general purpose transient voltage suppressor designed to protect sensitive electronics and components from voltage spikes and surges. It features superior clamping capability, and low leakage current, and is primarily used to protect automotive electronics and components, as well as consumer electronics and IT hardware, from various damages.
