TVS diodes are a wide range of devices used to protect electronic equipment from high voltage spikes. The MA1.5KE170AE3 is a transient suppressor diode designed to safely dissipate high voltage spikes and protect sensitive electronics. This article will discuss the application field and working principle of the MA1.5KE170AE3.

Application Field

The MA1.5KE170AE3 is a unidirectional Transient Volt-Second Suppressor (TVS) diode. It is designed for transient pulse Energy suppression in electronic circuits. It is suitable for a wide variety of applications such as consumer electronics, automotive, communication systems, and industrial applications. It is typically used in applications which require high-power handling capability, such as surge protection of DC-DC converters, inrush current suppression, and protection of automotive ECU\'s from high voltage transients.

Features and Specifications

The MA1.5KE170AE3 has a peak pulse power rating of 175 Watts, a breakdown voltage of 170 Volts, and a breakdown voltage of 1.5 Amps. It is rated for operation at temperatures from -55℃ to +135℃. It has a fast response time and can absorb high energy transients. The device is RoHS compliant and is Halogen free.

Working Principle

The MA1.5KE170AE3 TVS diode works by diverting surge current away from sensitive components or circuits. At normal operating voltages, the diode behaves like an open switch, allowing no current to flow. However, if the voltage level exceeds the Breakdown Voltage (V BR ) of the device, the diode becomes conductive and diverts the surge current around or away from the protected components. The maximum allowed surge current is limited by the Peak Pulse Current rating (I PP ) of the diode. Once the surge is dissipated, the diode reverts to its original state, isolating the protected components from the surge.

In conclusion, the MA1.5KE170AE3 Transient Suppressor Diode is a high-performance device used for transient surge protection. It has a high peak pulse power rating and a wide operating temperature range, making it suitable for a range of applications. It works by diverting surge current away from sensitive components or circuits, protecting them from damage.
