The 824540700 TVS diode series has a variety of application fields and working principles. It is designed for a variety of consumer electronics devices, automotive applications and industrial use.

Applications

The 824540700 TVS diode series is ideal for general-purpose protection in automotive, manufacturing, consumer electronics, and medical applications. It protects delicate transactions from the electrical over stress (EOS) often produced near to sensitive parts of circuits. Over voltage protection circuits may also be built in different products like portable devices to prevent damage from voltage transients from power sources, such as switches, lightning strikes and electrostatic discharge (ESD).

In addition, the 824540700 series is suitable for installation in vehicle electronics, satellite and radio antennas, and metal-oxide field-effect transistors (MOSFETs). Solid-state switches also benefit from its use. In consumer electronics, TV set-top boxes, digital video recorders (DVRs), and other consumer audio/video components can be safeguarded from high-voltage transients with the 824540700 TVS diode series. The 824540700 protective diode can be applied to medical products and equipments, such as pacemakers and X-ray machines.

Working Principles

The 824540700 TVS diode series operates on the simple principle of the junction break-down of anti-parallel PN junctions in reverse-blocking mode. The diodes provide a shielded junction to prevent the penetration of high-voltage transients, creating a high resistance, which in turn, limits the current that can flow between the junctions thus protecting the device from damage. In a sense, the 824540700 protective diode is like a current limiter.

When subjected to a high voltage transient, the 824540700 TVS diode series immediately breaks down and reduces the amount of voltage across the junction. After the transient has passed, the diode reverts to a non-conductive state, allowing the current to flow normally. In this way, the diode works as a natural surge arrester, safely dissipating away most of the excess energy before too much of it reaches the part of the circuit that needs protection.

Conclusion

The 824540700 TVS diode series is designed to protect fragile circuits from high-voltage transients. It is a cost-effective solution for automotive, communication, consumer electronics, and medical application where high-voltage protection is needed. Its simple working principle of the junction break-down of anti-parallel PN junctions creates a high resistance, allowing the current to flow normally after a transient has passed.
