JAN1N4470C application field and working principle

Introduction to JAN1N4470C

The JAN1N4470C (also referred to as 1N4470C, 1N4470, JAN1N4470 or JAN1N4470) is a single Zener diode produced by Motorola Semiconductor and manufactured by Meritec Semiconductor. It is a low current diode with a low reverse voltage rating of 5 Volts. This device is primarily used for the purpose of creating a stable reference voltage.

Application Field of JAN1N4470C

The JAN1N4470C is used in a variety of applications which require a stable reference voltage including, but not limited to, power supply circuits, voltage regulators, camera circuitry, computer diagnostic equipment and medical equipment. Its 5 Volt rating allows it to be used in circuits where a higher voltage needs to be regulated.

Working Principle of JAN1N4470C

The JAN1N4470C diode operates on the principle that when current passes across it in one direction, it will produce a stable 5 Volt reference voltage in its other direction. This voltage is stable and not affected by the variations in current passing across the diode. The diode accomplishes this through its built-in Zener diode effect.When a current is applied across the diode in the forward direction, it creates an electric field across the diode junction that causes a free electron current flow. This free electron current is attracted to a layer of positive ions within the semiconductor material. The flow of these free electron currents results in a voltage rise across the semiconductor junction. This voltage rise is called the Zener breakdown voltage or Zener voltage. The Zener voltage is determined by the physical characteristics of the semiconductor material and is typically in the range from 0.5 to 55 Volts.When the forward voltage across the diode is increased to a point higher than the Zener breakdown voltage, the diode creates a reverse direction current flow. This reverse current flow causes the diode to maintain the voltage across its terminal at the Zener breakdown voltage. This voltage remains stable even when the forward voltage applied to the diode varies.In the case of the JAN1N4470C, the Zener breakdown voltage is 5 Volts resulting in 5 Volts being constantly present across the terminals of the diode. This voltage provides a stable reference voltage which can be used in a variety of applications.

Conclusion

The JAN1N4470C is a single Zener diode produced by Motorola Semiconductor and manufactured by Meritec Semiconductor. The diode is primarily used for the purpose of creating a stable reference voltage and is used in a variety of applications including power supply circuits, voltage regulators, camera circuitry, computer diagnostic equipment and medical equipment. The JAN1N4470C operates on the principle that when current passes across it in one direction, it will produce a stable 5 Volt reference voltage across its terminals. This voltage is determined by the physical characteristics of the semiconductor material.
