TVS - Diodes are used to protect sensitive electronics and components from excessive overvoltage electrically caused through lightning strikes, abrupt high voltage discharges, power inductive loading from large motors and many other unpredictable events. They are designed to provide a “sensitive” and “clamping” function on an electric circuit, limiting the voltage surge to a level that the vulnerable components on the circuit can withstand safely without permanent damage occuring. One common type of TVS - Diode is theMXL1.5KE12AE3. This diode features some notable benefits that make it particularly suitable for a wide range of applications where transient protection is needed.

The MXL1.5KE12AE3 is constructed using proprietary low voltage, low resistance PN junction technology. Its main application field and working principle can be summarized as follows:

Application Field: It is mainly applied to the overvoltage and surge protection of mobile communications, electronic data processing equipment, industrial and commercial electronics & electronic equipment.

Working Principle: The functionality of the diode puts it into the category of a bidirectional Transient Voltage Suppressor (TVS) Diode. It typically exhibitsForward Bias Breakdown Voltage which is specific to the diode and is measured prior to shipment. This critical voltage determines the level at which the device will start conducting current when a positive voltage is applied to the anode terminal of the diode.

The performance of the MXL1.5KE12AE3 is highly superior. According to its datasheet, when subject to a positive voltage greater than its 25V breakdown voltage, it will begin to conduct at less than 1mA. It has a highly reliable electrostatic discharge of 8kV, and can withstand surge currents up to 150A. This makes it an ideal choice for many applications requiring superior protection.

The MXL1.5KE12AE3 also has great tolerance for high power pulses. It can withstand power pulses ranging from 10µs - 10ms with a peak pulse current rating of 185A. Furthermore, it has excellent clamping protection, meaning that if a voltage spike is greater than the threshold, it will rapidly conduct in order to limit the peak voltage. This ensures the device will not suffer long term damage due to excessive current.

The MXL1.5KE12AE3 has a highly stable thermal resistance of up to 25°C/W. This means that it will not suffer too much heat build-up durig high power discharges, allowing it to remain stable and nominal voltage will remain constant. This is very important, as some of the more susceptible components on a circuit can be easily damaged due to excess heat, making the MXL1.5KE12AE3 an invaluable resource for many applications requiring protection.

The MXL1.5KE12AE3 also has a high speed detection rate. It can detect transient overvoltage in as little as 1μs, allowing it to offers protection under the most demanding of short term excursions. This is very important to protecting many components on a circuit that may not be able to handle a prolonged excessive voltage.

In summary, the MXL1.5KE12AE3 Transient Voltage Suppressor (TVS) Diode is one of the most reliable and versatile surge protection devices on the market. Its superior protection capabilities, together with its reliability, durability and resistance to thermal damage make it a perfect choice in many applications where protecting sensitive electronics from excessive voltage is critical.
