MAPLAD18KP8.0CA

TVS diodes, also known as transient voltage suppressors, are a type of semiconductor device used to prevent damage to sensitive electronics during power glitches, overcurrent and electrostatic discharge (ESD) events. In particular, the MAPLAD18KP8.0CA is a sub-type of TVS diode specifically designed for automotive circuit protection. In this article, we will explore the application field and working principle of the MAPLAD18KP8.0CA.

Application Field

The MAPLAD18KP8.0CA is designed for the automotive environment and offers higher continuous operating temperatures and voltage than the standard TVS diode. It is typically used in high current automotive applications such as junction boxes, ECUs, and safety-critical components, given its robust design and enhanced protection features. It is capable of handling high voltages up to 18 volts for single-line events and 32 volts for differential line events, making it suitable for use in a wide range of automotive industry applications.

Additionally, the MAPLAD18KP8.0CA provides protection against ESD events with a capability of up to 25kV per human body mode, 15kV per machine model and 6kV per induced air gap discharge. It is also AEC-Q101 compliant, meaning it has met stringent automotive quality standards, making it suitable for use in mission-critical automotive electronic devices.

Working Principle

The MAPLAD18KP8.0CA is a bidirectional TVS diode, meaning that it is capable of clamping transient voltages in either direction. It works by intercepting potentially damaging voltage spikes and shunting them to ground, thereby preventing the associated electronics from having to suffer the effects of high current levels.

The MAPLAD18KP8.0CA is designed with an integrated ESD clamp in parallel with the TVS diode that guards against ESD events. This capability prevents false triggering due to over-voltage and ESD events, ensuring that the device is protected against both ESD strikes and transient electrical surges. Additionally, the device is designed with a integrated dual diode in series with the TVS diode, providing connection to the positive and negative potentials of an ESD pulse so that the device is not damaged by reverse bias current.

Conclusion

The MAPLAD18KP8.0CA is a highly reliable and robust TVS diode specifically designed for use in the automotive industry. It is capable of handling high voltages for single-line and differential line events and is compliant with AEC-Q101, ensuring that it is suitable for use in mission-critical devices. Furthermore, its integrated ESD and dual diode technology make it a viable choice for a variety of applications, making it an ideal choice for automotive circuit protection.
