A Look at a Specific Zener Diode

N 4764CPE3/TR8 is just one type of Zener diode, a type of diode used in many different applications. But what does it do specifically, and how does it work? Let’s dive deeper into this particular Zener type and explore its application field and working principle.

Application Field

N 4764CPE3/TR8 are diodes often used in camera flashes and automotive circuits. Automotive circuits in particular have seen increased use of Zener diodes like the N 4764CPE3/TR8, as automotive manufacturers look for parts that are strong, reliable and designed to last. These specific diodes are used as standard shunt regulators in automotive electronics.

Working Principle

The N 4764CPE3/TR8 Zener diodes operate on the principle of Zener breakdown. Zener breakdown occurs when a diode is placed in a reverse biased situation and a certain voltage is reached. When the voltage reaches a certain level, it results in a breakdown in the diode, allowing for current to flow in the reverse direction. This breaks down the diode’s “valence” bands and frees electrons which then travel in the reverse direction.

That current then becomes stabilized. As the current then rises or lowers, the voltage remains fairly consistent, as long as the breakdown voltage is not surpassed. The diode itself, along with other components, will clamp the voltage at a certain level. The value of the clamping voltage is determined by the Zener voltage of the diode. The Zener voltage of the N 4764CPE3/TR8 is approximately 6.8V.

Conclusion

The N 4764CPE3/TR8 is an important type of Zener diode and is often used in automotive applications. It operates based on the principle of Zener breakdown, where a certain voltage is reached and the diode breaks down and allows for current to pass in the reverse direction. The voltage is stabilized and clamped at a certain value, determined by the Zener voltage of the particular diode.
