TVS diodes are components used mainly for protecting circuits or systems. The MPLAD15KP40A is a unidirectional TVS diode, whose application fields and working principle will be discussed in this article.

Application fields

The MPLAD15KP40A is a unidirectional diode and is mainly used for protecting electronic circuits against stress caused by transient voltages, such as those generated by electronic fast transients (EFT), electrical fast transients (EFT), lightning, electrostatic discharges (ESD) or inductive load switching. Due to its low clamping voltage, it is also used for data signal line protection. It has an operating breakdown voltage of 15 V-40 V, hence it can be used for protecting circuits operating in the 15 V-40 V range. Additionally, it has a positive maximum operating temperature of 85 °C, making it suitable for applications where higher temperatures are expected and it can be used for both high and low voltage applications.

Working principle

The working principle of the MPLAD15KP40A is quite simple. It is designed in such a way that, when the voltage in an electronic circuit reaches certain levels, it is able to instantly activate and suppress any voltage that is above these levels. Essentially, it works by diverting a surge or spike of voltage away from sensitive circuits and dissipating it as heat, thereby protecting the circuit from failure.

When the transient voltage spikes, the diode switches on and the overvoltage is diverted to a low impedance path, which is located in the body of the diode. This then diverts the electricity to the heat dissipation surface of the diode, and the excess current is dissipated as heat quickly. This allows the voltage levels in the circuit to be maintained within safe levels, thus protecting the circuit from damage.

Conclusion

The MPLAD15KP40A is a unidirectional TVS diode, which is mainly used for protecting electronic circuits against transient voltages, such as those generated by EFT, EFT, lightning, ESD or inductive load switching. Its working principle is to divert a surge or spike of voltage away from sensitive circuits and dissipate it as heat, thereby protecting the circuit from failure. It is suitable for applications where higher temperatures are expected and it can be used for both high and low voltage applications.
