TVS - Diodes, small as they are, can be incredibly impactful in emergency protection circuits, such as those found in mobile phones. The CD214B-T45CALF is a device designed and manufactured by Central Semiconductor Corporation, making a long line of TVS diodes in the T-series for a wide variety of applications. It is designed to be reverse-mountable, which helps it protect from high voltage or current overshoot in cramped and narrow spaces.

The CD214B-T45CALF is an ultrafast diode, with the capability of clamping overvoltages within 1.9 nanoseconds. This low clamping time is far superior to mechanical relays, which typically have a response in the milliseconds. Its operating current is an impressive 200V, with a possibility for up to 500V of continuous blocking voltage. This makes it possible to withstand and protect against transients in high frequency and high power applications.

Now let’s move to its application field. It’s designed for a range of special purpose applications, but it’s particularly effective against ESD, EFT, and surge damage in LCD modules, optical modules, and backlighting systems. Those electronics can be sensitive to sudden current spikes, and the CD214B-T45CALF is a great solution for avoiding those damages quickly and conveniently.

So what’s the working principle behind this device? It works by maintaining two electrodes, a combination of anode and cathode, which can enter conduction if there is a sharp voltage spike. When the trigger does occur, the current takes a shortcut and is diverted away from the active components of the electronic device, thereby maintaining the integrity of the system.

In order to identify the correct working voltage level for the CD214B-T45CALF, an important factor to consider is the peak pulse voltage of the device. The peak current level, or peak pulse current, is the maximum current the diode should be exposed to without being damaged. It’s important to take these measurements into account when choosing the right TVS diode for the application at hand.

The CD214B-T45CALF is an impressive piece of sturdy and reliable circuitry, designed to protect sensitive and valuable devices from voltage overshoots and transients. It’s easy to mount and suitable for a range of special purpose applications, and can be specified for peak pulse voltages of up to 500V. It provides a crucial buffer between electronic systems and voltage spikes, and it’s no wonder why it’s such a popular choice for mobile phone protection circuits.
