824501511 Datasheet/PDF824501511 is a kind of Transient Voltage Suppressor (TVS) Diodes. It is mainly used for decreasing and limiting surge voltages or peak current. It can also provide protection against electrostatic discharge and other transient voltage events.
The 824501511 has a robust glass (DO-214AA) package, which gives superior performance, along with a wide operating temperature range of -55℃ to +125℃. It has a high peak pulse current of 1.5kW, a working voltage of 2.55V to 5V, and a breakdown voltage of 5V. This makes it highly versatile and applicable in a variety of fields.
Applications
TVS diodes are widely used in the protection of electronic signal lines and power supplies from large transient voltages or currents, and the 824501511 is no exception. It can be used in all kinds of computer peripherals, such as USB, PCI, sockets, and so on. It can also be used in the power supply circuits of domestic and industrial electrical appliances, including motor control circuits. TVS diodes can improve the efficiency and reliability of the products they are employed in greatly.
Since 824501511 provides protection from electrostatic discharge (ESD), it is also extensively used for Human Body Model (HBM) protection in a wide range of portable electronic devices, such as mobile phones, phones, and PDAs. It can also be utilized in communication systems, including satellite, high frequency, and so on.
Working Principle
The primary operation of 824501511 is done by the zener diode. When the transient voltage exceeds the pre-determined breakdown voltage (VDBR) of the 824501511, the zener diode begins to conduct, and short-circuits the over-voltage to the ground. This helps to reduce surge voltage down to a permissible level. When reverse bias voltage reaches the peak pulse power (PPP) of the diode, it conducts after a very short period of time.
When the transient voltage is removed, the zener diode is quickly reset to normal bias condition, and the 824501511 is once again ready to offer protection. The high PPP of 824501511 enables it to absorb large peak current, improving system reliability and prolonging the product lifespan.
