1.5KE120ARL

TVS (transient voltage surge) diodes are a type of surge-protection device used in a wide variety of applications to protect components from the damaging effects of transients, such as electrical spikes, voltage surges, and lightning strikes. A TVS diode is typically a unidirectional (one-way) device that fast-acts to divert the voltage away from sensitive electronic components before it has a chance to cause damage.

The 1.5KE120ARL is a type of TVS diode that is widely used in a wide range of industrial, automotive, and commercial applications. It is designed to provide protection up to 130V for 1ms or 20A for 8/20μs pulse. It is constructed from a ceramic body, a capacitor, and a PN junction diode in a single package.

The 1.5KE120ARL has an operating junction temperature range of -55 to 125°C and is able to handle high voltages and currents with a response time as short as 8/20μs. It is also designed to dissipate power dissipation levels up to 2W for short time periods, which is sufficient for most applications.

The 1.5KE120ARL is typically used in applications where transients could cause damage, such as automotive, computer, and industrial equipment. It is also commonly used in applications where overvoltage might occur, such as in the protection of power supplies from overvoltage transients. The 1.5KE120ARL is also often used in power supply protection circuits and as an output clamp for AC- DC converters.

The working principle of the 1.5KE120ARL is simple. When the input voltage exceeds the rated voltage, the diode turns on, diverting the excess voltage away from sensitive components. This prevents damage to the components and ensures that the circuit functions correctly. The diode also has a reverse leakage current of less than 0.1uA, which prevents the diode from conducting current in the reverse direction.

The 1.5KE120ARL is a reliable and cost-effective solution for providing protection against overvoltage transients. Its fast response time and high breakdown voltage make it a suitable choice for a wide variety of applications. With its wide operating temperature range and low power dissipation, it is an ideal solution for applications where transients may cause damage, and where surge protection is required.
