MA1.5KE39A is a part of Transient Voltage Suppressor (TVS) Diode family, which is designed to protect sensitive electronic equipment from lightning, accelerated transients and other electrical pulse threats. It has many application fields and working principles.

The MA1.5KE39A is basically a fused device, which primarily guards over-voltage conditions, generated from Electrostatic Discharge (ESD) or any such sources, and Clamped to a safe level. It’s made of two circuit protection devices – TVS and an integrated PTC fuse in a single package. The integrated fuse Current Rating value is 39A.

The working principle of MA1.5KE39A’s, is that when an excessive surge current flows through the device, its PTC part (an over-temperature protection device) begins to heat up, a switch action occurs in which resistance increases significantly, limiting the surge current to safe levels. As a result, the TVS component takes effect, simultaneously clamping the over-voltage condition and dissipating energy into the atmosphere.

One key application field for MA1.5KE39A is protecting the power systems in all kinds of automobiles from transients and lightning strike. The integrated fuse part of the device makes it suitable for complicated automotive power circuit protection in which fusing function is needed. Moreover, MA1.5KE39A is not only applied to automobiles, but also widely used in different industrial equipment, digital home appliances, IT equipment, and other applications.

Voltage and current ratings of MA1.5KE39A device usually range from 5V to 170V, showing excellent surge current of up to 41.3A, and excellent clamping ratio of 8V/3A. Its robust design and capability to handle high pulse power make it popular in power and telecom applications. It is flame retardant, with UL 94 V-2 ratings, positive temperature coefficient, extremely low turn on voltage, and quick response time.

To sum up, MA1.5KE39A is a exceptional part of the TVS diode family, which can operate in hostile environmental conditions with superior protection and reliability. It is highly recommended when it comes to protecting power switching designs, automotive power systems, and telecom lines.
