Diodes - Zener - Single - 1N5928P/TR12 Application Field and Working Principle

The 1N5928P/TR12 Zener single diode from Diodes Incorporated is a reliable and highly efficient semiconductor device that is used to damp out voltage fluctuations and other electrical signals in order to regulate an electrical circuit. It is a general-purpose device and is suitable for numerous applications in industrial, automotive, consumer, and telecommunications systems. Its wide range of operating voltages, low reverse leakage currents and minimal forward voltage drop makes it a great choice for applications requiring protection from electrical overvoltage or static discharge.

Applications and Advantages

The 1N5928P/TR12 is best suited for low-power, low-voltage applications such as circuit protection and power efficient applications such as DC motor control. It is also ideal for protecting data lines and other delicate circuitry from overvoltage and static discharge. Since its operating voltages range from 1 to 6.2 volts, it can be used as a voltage reference in many applications where tight voltage regulation is required. Apart from its wide range of operating voltage levels and very low reverse leakage current, the 1N5928P/TR12 offers many advantages over other zener diodes. It has a high current rating (up to 150 mA), a low thermal resistance (down to 0.50 °C/W) and a maximum junction temperature of 175 °C. In addition, it has a high surge current handling capability (200 watts) and supports both reverse and forward current.

Working Principle

The 1N5928P/TR12 Zener diode operates by allowing a small amount of current to flow through the diode when an applied voltage is higher than its threshold voltage, called the “Zener voltage”. This current creates a small voltage drop across the diode, bringing the voltage level down to the Zener voltage and allowing the circuit to regulate the voltage. In other words, the 1N5928P/TR12 regulates the voltage level by allowing a small amount of current to flow in the opposite direction. When the voltage level of the applied voltage is lower than the Zener voltage, no current is allowed to flow through the diode. This means that the 1N5928P/TR12 is completely non-conductive until the applied voltage exceeds the Zener voltage rating. This makes it an ideal choice for applications requiring high voltage isolation and reliable voltage regulation.

Conclusion

The 1N5928P/TR12 Zener single diode is a reliable, efficient, and cost-effective way to regulate voltage levels in low-voltage and low-power applications. It can handle a wide range of operating voltages and delivers exceptional performance in demanding circuit protection, voltage regulation, and static discharge protection applications. The device can withstand high surge current and has a low thermal resistance and reverse leakage current, making it an ideal choice for countless applications.
