1N4487 is a high-performance, high-system voltage, common cathode Zener diode. It is made of silicon planar epitaxial substrate, designed as an ideal choice for use in space-limited, high-reliability applications such as automotive, industrial, and commercial products. It is manufactured in an automated assembly line and tested in temperature ranges from -65℃ to +150℃.
1N4487 is widely used in electronic circuits, from speakers to amplifiers. The device is also used to increase signal strength or to connect two devices with different input and output voltage/current levels for efficient power transfer. The device is also often used to protect circuits from excessive current, such as overloading and transient overloads.
The purpose of the 1N4487 is to provide a stable voltage reference in a wide variety of conditions and to protect components, circuits and systems from currents that are too large. It is designed to efficiently convert the incoming voltage into a regulated reference voltage. The device typically features a low forward voltage drop and high reverse current capabilities.
The working principle of the 1N4487 is simple. It acts as a voltage regulator, allowing voltage to pass through it only up to a certain pre-determined voltage level. When the voltage level is exceeded, the excess voltage will be diverted away from the main circuit, preventing damage to the components, circuits and systems.
The 1N4487 is used primarily in applications in which the incoming voltage needs to be regulated for the best performance of the device. For example, it can be utilized in automotive systems, digital home audio systems,industrial measurement meters, and pulse modulators. The device is also often used in DC-DC converters, LDO (low dropout regulator) circuits, mobile phones, DC-AC inverters, and medical systems.
In conclusion, the 1N4487 is a versatile and high-performance Zener diode that is suitable for a wide variety of applications, from automotive systems to medical systems. Its low forward voltage drop and high reverse current capabilities make it an ideal choice for use in high-reliability applications, and its efficiency and stability ensure the protection of electrical elements and systems from excessive current.
