TVS diodes, also known as transient voltage suppressors, are an electrical component that protects electronic equipment from surges caused by electrostatic or induced voltages. The 1V5KE91A series provides protection from transients up to 600 Watts of peak pulse power at 10/1000 microseconds pulse width. It operates within a voltage range of 5.5 to 180V, and is capable of repetitive peak power dissipation up to 600W.

These TVS diodes offer the necessary protection to safeguard today’s modern semiconductor technology in various equipment including notebook computers, power supplies, motor controllers, and medical devices. In addition, these devices feature excellent clamping capability, very fast response time (less than 1ns), and ratings of up to 6kV for AC transient voltage suppressing.

The working principle of the 1V5KE91A series of TVS diodes relies on its ability to quickly limit the peak voltage presented at the device’s protected terminals to a safe level. When a voltage transient momentarily rises above the normal operating voltage, a current surge results, and this builds in di/dt. This in turn triggers the device to act like a low impedance connection, allowing large amounts of current to flow, thereby reducing the voltage to a safe level. This provides a high level of protection from transients, without degrading the normal operating voltage.

The 1V5KE91A series of TVS diodes feature a wide operating temperature range, from -55°C to 125°C. The ultra-low capacitance values of these devices, ranging from 0.3pF to 3.2pF, make them well-suited for high speed digital systems. Furthermore, these devices come in a variety of case sizes, from SMA to SOT-23, thereby providing designers with maximum flexibility when space is a concern.

In conclusion, the 1V5KE91A series of TVS diodes provide reliable protection against transients, while having the capability to repetitively withstand peak power dissipation levels up to 600W. Furthermore, these devices feature a high surge current level, as well as an ultra-low capacitance level. Moreover, they come in various case sizes, and are designed to operate over a wide temperature range. They are ideally suited for protecting various types of semiconductor equipment, including notebook computers, power supplies, motor controllers, and medical devices.
