MPLAD15KP75CAE3

TVS - Diodes

TVS, or Transient Voltage Suppressor diodes, are unidirectional semi-conductor devices that are designed to protect against sudden changes in voltage. They act as a barrier between an incoming circuit and the rest of the system, and dissipate any transient overvoltages or overshoots before they reach the protected load. The MPLAD15KP75CAE3 is one of the most common types of TVS diodes and is used in a wide range of applications.

Application Field

The MPLAD15KP75CAE3 is typically used in consumer electronics, automotive, industrial, and nuclear applications. It is often used to protect against electrostatic discharge (ESD), electrical fast transients (EFT), and other types of transients. It can be used in both AC and DC applications and is able to withstand voltages up to 1500 volts peak. It is also RoHS compliant, making it suitable for use in high voltage systems.

Working Principle

In short, the MPLAD15KP75CAE3 works by diverting the transient pulse away from the protected load. It does this by essentially acting like a clamped diode that can conduct up to a certain voltage, and will then start to conduct more heavily as the voltage increases. This clamped diode is then coupled with a zener diode that starts to conduct heavily once the initial voltage is exceeded.

The zener diode then starts to conduct heavily, and it is this that is responsible for diverting the majority of the transient pulse away from the protected load. This also works to protect the circuit from reverse voltages, and the device will activate almost instantly in response to a transient pulse.

Once the transient is over, the device then enters its release state. During this state, if the voltage is still above the release voltage, then the device will continue to conduct heavily. However, if the voltage falls below a certain level, then the device will enter into a recovery state in which it will reduce the amount of current that is flowing through it.

Due to its fast response time, the MPLAD15KP75CAE3 is ideal for use in applications where the protection system must respond almost instantly to transient events. This makes it particularly suitable for use in high-speed circuits, where large transients can occur very quickly.

Conclusion

The MPLAD15KP75CAE3 is a type of TVS diode designed to protect against sudden changes in voltage. It is a unidirectional device that is extremely fast in its response time due to its clamped and zener diode design. It is a very popular device and is often found in consumer electronics, automotive, industrial, and nuclear applications, making it suitable for a wide range of uses.
