Diodes - Zener - Single

3EZ16D/TR8 is a type of single Zener diode from STMicroelectronics which is widely used in consumer and industrial applications. This diode is mainly constructed to generate a constant and reliable voltage for the DC-DC converter, voltage regulator, and voltage stabilizer. Because of its features like wide working range, low leakage current and good heat transfer, it has become the most preferred choice across all voltage regulators.

Application Field

3EZ16D/TR8 is mainly suited for consumer and industrial applications, like stabilizing the load voltage, regulating the output voltage and in power compensating circuits. This diode can also be used in voltage or current monitoring, triggering thyristors and SCRs, etc. The 3EZ16D/TR8 is mainly used in consumer and industrial applications, like stabilizing the load voltage, regulating the output voltage and in power compensating circuits. It is also used for adjustable power —supply, electronic ballast, inverters and pulse generation.

Working Principle

The working principle of Zener diodes is based on the breakdown of P-N junction formed by two semiconductor materials of different conductivity. When a reverse bias is applied, the depleted region becomes extremely thin and has the capacity to sustain a very large electric field. When the voltage exceeds a certain level, called the “Zener voltage”, the diode starts to express a negative resistance character, allowing the current to flow in the reverse direction. Eventually, the current passing through this reverse-biased junction is proportional to the voltage difference and the Zener voltage.

The 3EZ16D/TR8 Zener diode has a constant Zener voltage of 16V. Its maximum reverse leakage current is 25µA, with a power dissipation of 500mW and operating junction temperature of -55C to +150C. Its thermal resistance limits the temperature increase with respect to the power dissipation and can then protect the circuit from being damaged.

The 3EZ16D/TR8 device is a fast electrical diode. A fast diode is a type of diode that is designed to be operated in less than 100 microseconds. This is a very important feature for high-speed switching circuits. The fast switching speed of the diode helps the device to achieve a more efficient power conversion and operation.

Conclusion

The 3EZ16D/TR8 Zener diode from STMicroelectronics is a high-performance single Zener diode that finds a wide range of uses in consumer and industrial applications. Its features, like high power dissipation, low reverse leakage current and fast switching speed make it ideal for regulating the output voltage of certain devices, as well as triggering thyristors and SCRs.
