TVS - Diodes: 824550281 Application Field and Working Principle

Transient Voltage Suppression (TVS) diodes are an important component in protection circuits that are used to limit surges, overvoltage, and ESD (electrostatic discharge) from damaging sensitive electronic components and devices. The 824550281 series of TVS diodes are manufactured by TELEDYNE LECROY, a renowned manufacturer specializing in the production of high-quality TVS diodes. This article will discuss the application fields and working principle of the 824550281 series TVS diodes.

Application Fields of 824550281 Series TVS Diodes

The 824550281 series of TVS diodes are mainly used in the following application fields:

• Computer peripherals, such as hard disk drives, motherboards, network cards, and graphics cards.
• Consumer electronics, such as digital cameras, MP3 players, mobile phones, and PDAs.
• Industrial control, such as PLCs, UPSs, motor controllers, and I/O modules.
• General consumer protection, such as LCD monitors, LED lighting, and power tools.

Working Principle of 824550281 Series TVS Diodes

The working principle of the 824550281 series of TVS diodes is based on the avalanche break down mechanism. Under normal operating conditions, the TVS diode behaves like an open circuited device, allowing no current to flow through it. However, when a high voltage spike occurs, electron and hole pairs are generated within the device, resulting in an avalanche break down. This causes the TVS diode to suddenly reduce its impedance from infinity to a minimum of a couple of ohms. The TVS diode then acts as a short, thus limiting the voltage and protecting the circuit from damage.

Advantages of the 824550281 Series TVS Diodes

The 824550281 series of TVS diodes offer many advantages. These diodes are constructed using advanced manufacturing techniques to ensure high reliability. They are designed to operate in high temperatures up to + 175°C with minimal leakage current. They are also highly compatible with a wide range of technologies, such as logic, MOSFET, bipolar, and IGBT. Moreover, the 824550281 series of TVS diodes have a low capacitance that reduces power dissipation and enables faster switching speeds.

Conclusion

TVS diodes have become a crucial component for protecting electronic circuits from overvoltage and ESD. The 824550281 series of TVS diodes manufactured by TELEDYNE LECROY have many advantages such as high reliability, high temperature capability, and compatibility with various technologies. The working principle of these TVS diodes is based on the avalanche break down mechanism, wherein the diode abruptly reduces its impedance under high voltage spikes, thus limiting the voltage and protecting the circuit from damage.
