Automotive applications use the 824521750 for ESD protection on Automotive Control Modules (ECMs) such as Engine Control Modules (ECMs) and Airbag Control Modules. Industrial applications of the 824521750 include Industrial Control Systems (ICS), Robotics, and Programmable Logic Controllers (PLCs). In addition, the 824521750 can be used in commercial applications such as PC motherboards, servers, and communication systems. Lastly, in the medical field the 824521750 can be used to protect medical imaging and diagnostic equipment from overvoltage and ESD damage.

Working Principle

The 824521750 is an ESD and overvoltage protection device that operates on principle of “avalanche break down”. When a voltage across the diode exceeds the breakdown voltage of the diode, it is said to have "avalanched." The avalanche effect causes the diode to simply clamp the voltage at a safe level and conduct a large amount of current to ground. This current flow discharges the overvoltage and protects the circuit.The 824521750 also provides ESD protection which works very similarly. When an ESD event occurs, the 824521750 will avalanche and clamp the voltage at a safe level. The ESD induced current is then discharged to ground. This protects the circuit from potential ESD damage.

Conclusion

The 824521750 is an ESD and overvoltage protection device that provides high levels of protection from both ESD and overvoltage conditions. It is used in a variety of applications including automotive, industrial, commercial, and medical. The 824521750 operates on the principle of avalanche break down, where, when a voltage across the diode exceeds the breakdown voltage, it will avalanche and clamp the voltage at a safe level, discharging the overvoltage or ESD induced current to ground.
