Diodes - Zener - Single
A 1N4747CP/TR8 is a zener diode designed and manufactured by Texas Instruments. It is a two-terminal, hermetically sealed device that uses a high-performance silicon technology to provide electrical performance and reliability in a wide range of applications. The 1N4747CP/TR8 is a single-diode device capable of withstanding and handling reverse voltages of up to 15 volts. It is designed to be used in applications where voltages up to 15 volts could be encountered.
Application Field
The 1N4747CP/TR8 is designed for use in telecom, automotive, industrial and home appliances markets. It can be used in a wide range of DC voltage applications, including battery-based dedicated channel converters, receiver radio circuits, and 48V telecom power supplies. The 1N4747CP/TR8 is also suitable for applications such as emergency and emergency vehicle light systems, automotive batteries, solar energy systems, power cords, and power supplies.
Working Principle
The 1N4747CP/TR8 is a special type of diode, known as a zener diode. It is designed to allow current to flow in one direction only, however, it will also allow a reverse current to flow when the voltage across the diode exceeds the zener voltage. The zener voltage is determined by the amount of dopant impurity in the diode material and the temperature. The 1N4747CP/TR8 has an avalanche voltage rating of 15V and a breakdown voltage of 15V.
When the reverse voltage across the diode exceeds the zener voltage, it begins to conduct in a reverse direction. This reverse current will be regulated by the zener voltage just as it is limited by the forward voltage. This action is what enables the 1N4747CP/TR8 to be used in applications requiring a relatively constant voltage level, regardless of the input voltage. Additionally, it provides protection for electronic components in voltage sensitive circuits.
In general operation, the 1N4747CP/TR8 behaves as any regular diode; when the forward voltage exceeds the breakdown voltage of the device, current will flow in the forward direction. However, once the forward voltage drops below the breakdown voltage, the diode will again be in a reverse bias condition. The reverse current will then be limited by the zener voltage.
The 1N4747CP/TR8 is an integrated device consisting of a zener diode and a temperature compensated capacitance. This capacitance can provide temperature compensation over a wide range of temperatures. With its combination of high performance, a wide temperature range, and integrated temperature compensation, the 1N4747CP/TR8 is an ideal choice for a wide range of DC applications.
