Working Principle

The 1N5920PE3/TR12 is a single Zener diode. It works on two basic principles: breakdown and reverse current conduction. The breakdown principle means that when the diode is subjected to a voltage greater than its rated maximum reverse voltage (VR), it will begin to permit current to flow in a reverse direction. This is often referred to as “breakdown voltage”. The reverse current conduction principle means that when current passes through the diode in the reverse direction, it will cause a voltage drop, known as the “reverse voltage drop”. The combination of these two principles allows the diode to regulate voltage levels and protect other components from overvoltage.

The 1N5920PE3/TR12 has a moderate power rating at 1 W, so it is suitable for most general purpose applications. The diode has a breakdown voltage of 6.0 V and a reverse current rating of 0.5 uA. It is designed to handle up to 1 W of operating power and operate up to +105°C. It also has a low power consumption at 0.1 uA, making it suitable for battery operated applications.

The 1N5920PE3/TR12 offers excellent performance in critical applications. It is suitable for protection devices, such as in automotive applications, and is perfect for low voltage integrated circuits. The diode is also ideal for applications requiring fast switching, providing up to 100 kHz of operation.

In summary, the 1N5920PE3/TR12 is a single Zener diode that is suitable for a wide range of applications, including DC power supplies, charge pumps, rectifier bridges, regulators, voltage limiters, DC motor control, and power supply filtering. It offers excellent performance in critical applications and is capable of handling up to 1 W of operating power and operates up to +105°C. The 1N5920PE3/TR12 is perfect for low voltage integrated circuits, providing up to 100 kHz of operation.
