Single Zener diodes are a type of semiconductor diode that allows current to flow in one direction. They are used in a variety of applications for suppression of voltage transients, voltage regulation and other functions. The 1N4762APE3/TR8 is a glass-passivated single Zener diode specially designed for applications requiring high reliability and stability under varying temperature conditions. In this article, we will explore the application field and working principle of the 1N4762APE3/TR8.

Applications

The 1N4762APE3/TR8 is primarily used in display and backlight power supply applications in consumer electronic devices such as laptops, smartphones and digital cameras. It is also used for excess voltage protection for semiconductor integrated circuits, as well as for voltage regulation in line powered communication equipment, instrumentation and control systems. Furthermore, the 1N4762APE3/TR8 is used in low voltage switching circuits and AC/DC converters.

Working Principle

The 1N4762APE3/TR8 is a dual Zener diode composed of two separate Zener diodes connected in reverse parallel. In applications involving voltage regulation or transient suppression, the device is connected in such a way that negative breakdown voltage is supplied to a terminal. When the voltage on the cathode terminal rises above the Zener breakdown voltage, a current flows through the device in order to maintain a constant voltage level on the anode. In contrast, the other terminal maintains a constant voltage level irrespective of the voltage applied to the first terminal. As a result, the 1N4762APE3/TR8 is able to protect vulnerable areas of a circuit from overvoltages.

The 1N4762APE3/TR8 is designed to operate over a wide temperature range from -55 to +105 °C. Furthermore, the device features a glass passivation layer that provides improved resistance to thermal shock and voltage transients. Additionally, the device is capable of operating in a high voltage environment, up to 140 V for the 1N4762APE3. The maximum working current is also relatively high, ranging from 100 to 500 mA.

Conclusion

The 1N4762APE3/TR8 is a dual Zener diode designed for reliable and stable performance over a wide temperature range. It is used in a variety of applications, ranging from display and backlight power supply applications in consumer electronics, to excess voltage protection and voltage regulation in power systems. Additionally, the device is designed to operate up to 140 V and a maximum operating current of 500 mA.
