TVS - Diodes: CM1214-01DE Application Field and Working Principle

TVS - Diodes are widely used in many electronic devices to protect other sensitive components from electrical damage and to reduce interference in signal paths. The CM1214-01DE is a powerful transil diode designed to absorb transient voltage. It is used for TVS protection in high-speed I/O and signal line circuitry, computers, power supplies, and data communication devices.A TVS diode consists of two components: a voltage sensitive device and a conducting path. The voltage sensitive device is triggered by excessive electrical stress. When the voltage reaches a predetermined level, the conducting path is closed, allowing current to run through it instead of flowing through other sensitive equipment. The voltage of the CM1214-01DE is usually used to protect components from potential >14V spikes.When used in a circuit, the TVS diode protects other components by diverting electricity from the undesired components to the diode. This prevents further electrical damage, and ensures the circuit is functioning properly. The CM1214-01DE has a SURF20K peak pulse current, meaning it is able to handle high-speed pulse signals without compromising integrity, achieving high reliability and robustness.How does it work? When the TVS diode is triggered by increased voltage, the semiconductor device inside becomes a conductor, allowing current to flow through the diode and effectively dissipating electrical energy. The CM1214-01DE is triggered when voltage exceeds 14V, and turns off when the voltage returns to its normal level. This high voltage protection is ideal for protecting computers and other electronic devices from high voltage spikes or transients, which can cause permanent damage to the circuitry.The CM1214-01DE is also relatively simple to install. The diode can be placed on a board with ease, as it usually comes with two large solder pins for easy soldering. This makes it ideal for use in high-speed I/O and signal line configurations, as it can be quickly installed and configured.The major advantage of the CM1214-01DE is that it can effectively act as a short circuit when necessary, preventing more electrical current from flowing into the protected components. This is much more efficient than other protection methods, as the CM1214-01DE is able to dissipate energy much quicker and with better precision.Overall, the CM1214-01DE provides an effective solution to protect components from high-voltage transients and surges. It is a simple to use and cost-effective device, and can provide superior protection for high-speed I/O and signal line systems. It is also a reliable design, boasting a SURF20K peak pulse current, meaning it is able to handle more electrical current without compromising the integrity of the circuit.
