1.5KE39ARL

TVS (Transient Voltage Suppressor) diodes, also commonly referred to as TVS diodes, are one of the most common types of electrical components used to protect circuitry from high voltage overshoot, electrostatic discharge (ESA) and other types of surges. 1.5KE39ARL is a special type of TVS diode, which is specifically designed to provide high-level circuit protection against lightning strikes and other transients. This article will explain the application field and working principle of this special diode.

The application field of 1.5KE39ARL TVS diode includes gigabit ethernet, Modem and USB 2.0 protection, automotive electronics, telecommunication equipment, consumer electronics, base stations, radio transceivers, personal computers, and other electronic devices. The 1.5KE39ARL TVS diode is capable of handling peak repetitive voltage up to 39V, peak pulse current up to 14A, and pulse discharge current up to 300A. It also has an average power dissipation rating of 395W.

When it comes to the working principle of 1.5KE39ARL TVS diode, this device has two distinct modes of operation: non-destructive and destructive. In the non-destructive mode, the TVS diode is designed to absorb a certain level of electric energy without being damaged. When the surge voltage exceeds that certain value, the TVS diode will enter the destructive mode which is designed to absorb even higher electric energy. When the peak surge voltage exceeds a still higher value, the TVS diode will dissipate the energy through thermal energy transfer to its environment.

The 1.5KE39ARL TVS diode also has several features that make it especially suitable for protecting sensitive electronic devices. Firstly, its low capacitance and low clamping ratio make it perfect for protecting high speed communications circuits. Secondly, this device is capable of handling up to 10,000W of surge current over 25s or up to 1500W over 8/20μs. Thirdly, it has a wide operating temperature range of -55 to + 125oC.

In conclusion, the 1.5KE39ARL TVS diode is a specialized device designed for high-level circuit protection against transients, lightning strikes and other surges. This diode has a wide range of applications including Gigabit Ethernet, Modem and USB 2.0 protection, automotive electronics, consumer electronics, base stations, etc. It has two modes of operation - non-destructive and destructive - and several features that make it suitable for protecting sensitive electronic devices.
