YFZVFHTR4.3B Datasheet/PDFDiodes, particularly zener diodes, are electronic components used in a variety of electronic circuits. They are bi-directional devices, meaning they allow current to flow in either direction through them. The YFZVFHTR4.3B is one such diode and has a wide range of applications and a distinct structure and function.
This diode, when put into a series with a resistor, has a maximum power dissipation capability of 500mW. Its maximum reverse voltage rating is 5V. This diode can be used as a voltage reference device with constant voltage characteristics over a range of currents. The YFZVFHTR4.3B exhibits very low capacitance and is a good choice for use in high frequency and signal conditioning applications. It has a very low noise rating and is suitable for use in low noise signal applications.
The diode is made up of two distinct sections. The first section is an anode terminal and the second section is a zener layer. The zener layer acts as a barrier and only allows current to flow in one direction. This layer is connected to the anode terminal and limits the current flow from the anode to the cathode. When sufficient voltage is applied, the zener layer kicks in and prevents further current flow from the anode to the cathode. Thus, the current is limited to the voltage at which the diode breaks down. This breakdown point can be adjusted by altering the concentration of the doping agent in the zener layer.
There are many applications for the YFZVFHTR4.3B. Some of these include its use in voltage regulating systems such as power supply circuits and motor drives. It can also be used in overvoltage protection circuits, series regulator circuits and low power battery charging circuits. The device also has an application in clock and oscillator circuits, as well as in switching circuits, logic gates and amplifier circuits. The diode can also be used in sampling and demodulation circuits.
In summary, the YFZVFHTR4.3B is a zener diode that can be used for a variety of applications where a stable source of power or a constant voltage is required. Its two terminals and zener layer allow for a current limiting device with a precise voltage rating. The applications for this diode are wide ranging and it is an important component in any electronic circuit.
