Introduction: MA1.5KE82CAE3 TVS-Diodes

MA1.5KE82CAE3 belongs to the family of TVS-Diodes, a Transient Voltage Surge Suppressor (TVSS) device. The MA1.5KE82CAE3 is a unidirectional silicon avalanche diode intended to protect voltage sensitive components from induced transient overvoltages. This diode has a voltage standoff rating of 82 V and a power dissipation rating of 500 watts. It can protect equipment and circuits when transient overvoltages occur, such as the surges generated by lightning strikes, AC induction motors, and long cable runs.

Application Field

The MA1.5KE82CAE3 has a wide range of applications, including surge protection for AC power line, appliance power lines, industrial control systems, communication systems, personal computers, servers, set-tops, and other sensitive electronic equipment. It is also widely used in automotive, appliance, consumer, industrial, and home automation products.

Working Principle

The MA1.5KE82CAE3 is a unidirectional silicon avalanche diode. When presented with an overvoltage, it conducts the voltage and quickly dissipates it. The diode contains a voltage dependent breakdown element, which presents a low impedance path to the overvoltage. The diode is triggered when the overvoltage exceeds the rated voltage standoff. It clamps the voltage to a safe level and dissipates the energy generated by the transient overvoltage.The diode can handle high-energy pulses for duration up to 50µs. It has a temperature coefficient of -0.1% per °C, a surge life cycle of 120 cycles, and a typical capacitance of 2.4pF. The diode is available in several voltage and current ratings.

Conclusion

The MA1.5KE82CAE3 is a unidirectional silicon avalanche diode designed to protect voltage sensitive components from transient overvoltages. It has a wide range of applications, including AC power line, appliance power lines, industrial control systems, communication systems, and more. It has a voltage standoff rating of 82 V and a power dissipation rating of 500 watts. The diode can handle high-energy pulses for duration up to 50µs and has a temperature coefficient of -0.1% per °C.
