Today, there is a wide range of TVS diodes available, from basic single channel protection to advanced, high performance designs. The DLPT05-7 is one such device, which provides transient voltage surge suppression for high power lighting, power supplies and motor control applications, with a maximum rated protection of 7 A. In this article, we\'ll discuss the application field and working principle of the DLPT05-7.

Applications

The DLPT05-7 is suitable for a variety of different applications, but is specifically designed for surge suppression in high power lighting and power supplies. It can also provide protection for motor control systems, which are prone to transient voltage surges caused by lightning or power outages. The DLPT05-7 is also suitable for applications that require low current leakage and high isolation voltage, such as processors, LEDs and LCDs.

Working Principle

The DLPT05-7 is a radial-type TVS diode which uses silicon to protect against voltage spikes. The device is designed with three layers, consisting of a P+ layer, a N+ layer and a resistive layer, which are encapsulated in a ceramic material. When a voltage surge occurs, the P+ and N+ layers form a \'strong body diode\' which can effectively clamp the voltage to a safe level. The resistive layer is then used to provide additional protection against excessively high transient voltages.

The DLPT05-7 also features integrated overvoltage protection, which detects when the device is subjected to an overvoltage condition and shut off the electrical current automatically. This helps prevent damage to sensitive components and ensures reliable operation.

Conclusion

The DLPT05-7 is a radial-type TVS diode which provides effective transient voltage surge suppression for high power lighting, power supplies and motor control applications. It is designed with three layers which provide strong body diode protection, as well as integrated overvoltage protection for reliable operation. The DLPT05-7 is an ideal choice for a wide range of applications, due to its high performance and low leakage current.
