3EZ20D/TR8

Diodes - Zener - Single

The 3EZ20D/TR8 is an integrated power semiconductor device of the Zener diode type. Zener diodes are used principally in voltage regulation, where current needs to be kept within an acceptable range. This device, manufactured by Bourns, Inc., can be used to regulate voltage in a variety of applications, including electronics and power control systems.

Applications

The 3EZ20D/TR8 is designed to regulate a voltage of 20 volts. It can be used in a wide range of applications, such as consumer electronics, home appliances, industrial electronics, power control systems, and automotive parts. It is especially useful for applications needing long-term reliability, due to its exceptionally low leakage current and low temperature coefficient.

For these types of applications, the 3EZ20D/TR8 features a wide operating temperature range, from -55 to +150C. It is also robust in high vibration and shock environments, which makes it ideal for use in automotive and mobile applications. Additionally, the package has superior solderability, so it is able to withstand high temperatures during soldering.

Working Principle

The 3EZ20D/TR8 is a variation of the traditional Zener diode, which works by allowing a certain amount of voltage to pass through the diode before the diode rapidly switches to “on” mode, allowing the remaining current to pass through as well. This action has the effect of regulating the voltage. The specific value of the Zener Voltage can be set by adjusting the parameters in the diode’s design.

In the 3EZ20D/TR8, this action is controlled by an internal Zener voltage that is purposely set to achieve the desired voltage level. When the voltage across the diode rises above the Zener voltage, the diode begins to regulate the current, allowing the maximum current to be determined by the diode’s own characteristics. This ensures that the voltage across the diode stays at the desired level within a certain tolerance.

Conclusion

The 3EZ20D/TR8 is a Zener diode designed for voltage regulation applications. It features a wide operating temperature range and robust construction for demanding applications, such as automotive and power control systems. Its Zener voltage is set to a specific value so that the current passing through the diode can be regulated when the voltage rises above the set point. This makes it useful for maintaining accurate voltage levels in a variety of situations.
