Working Principle

The 1SMA4762-GT3TR is a current controlled Zener diode. Its operating principle is based on the use of a control current to define the voltage at which conduction of current effectively begins. When the external control current is high enough, the diode\'s breakdown process produces a precise, stable voltage level. The diode is constructed of a lightly doped layer, called the depletion layer, between the P and N type regions of the body. When the control current is applied, such as when the diode is arranged in series with a current source and regulated voltage source, the depletion layer widens, reducing the electric potential across the junction. This allows conduction to start and the diode’s output current is then determined by the control current across it and the supply voltage. The diode regulates the voltage by acting as a constant resistance to the flow of current. This ensures that the output voltage is stable, even when the input voltages fluctuate. As a result, the diode is ideal for power supply and voltage regulation applications, where precise levels of voltages are required.

Conclusion

In conclusion, the 1SMA4762-GT3TR is a single Zener diode designed for use in various electronic and electrical applications requiring precise voltage regulation. It is capable of providing stable voltage levels and controlling current flow in power systems, telecom, automotive, medical and industrial applications. Its working principle is based on the use of a control current to define voltage breakdown, allowing precise and reliable voltage regulation.
