TVS (transient voltage suppressors) devices are specially designed to protect vulnerable electric components from sudden and destructive voltage transients arising from sources such as lightning and electrostatic discharge (ESD). CM1242-07CP is a type of uni-directional TVS diode. It has a low dynamic resistance, fast response, and wide operating voltage range, making it an ideal choice for designers.

CM1242-07CP Application Field

The CM1242-07CP is designed for use in telecommunications, digital, networking, and computing applications. It is suitable for protecting equipment sensitive to overvoltage transients caused by electrostatic discharge (ESD), lighting, and other sources. The device can also be used to protect single channel telephone lines to provide reliable surge protection against overvoltage transients.

The CM1242-07CP is small enough for surface mount and is RoHS compliant, making it an ideal choice for high-density circuit boards. It can also be used in DC/DC converters, telecom line cards, home networking, and other consumer electronic devices.

CM1242-07CP Working Principle

The CM1242-07CP is a uni-directional TVS diode that acts as a voltage suppressor. It is designed to limit voltage spikes and protect vulnerable electronic components from overvoltage and short-term power surges. The device consists of a zener diode and a PN junction that act as the primary components in the protection circuit.

In normal operation, the CM1242-07CP operates in conduction and limits the voltage spikes that occur when a surge occurs. When the voltage exceeds the normal operating level, the device goes into conduction and dissipates the power of the surge. The device is designed to provide fast response and low-clamping voltage, allowing it to successfully protect sensitive components.

The CM1242-07CP can also be used to protect two-wire systems. Its low clamping voltage helps prevent AC power line disturbances from causing damage to sensitive electrical components. The device is also designed to protect ground loops that can be caused by inductance in the wiring. It can also help reduce the power consumption during operation and minimize the length of service outages.

Conclusion

The CM1242-07CP is a uni-directional TVS diode designed for use in telecommunications, digital, networking, and computing applications. It is capable of protecting equipment sensitive to overvoltage transients caused by lightning, electrostatic discharge, or other sources. The device has a low dynamic resistance, fast response, and low-clamping voltage, which help to protect vulnerable electrical components. In addition, it is RoHS compliant and small enough for surface-mount, making it an ideal choice for high-density circuit boards.
