The CRZ27 is a range of single, Zener diodes. They are available with a range of ratings and are a popular choice for applications requiring good reverse voltage breakdown performance. This article will explain the applications and workings of this series of components.

Applications

The CRZ27 series provides a range of breakdown voltages across a range of popular ratings, from 1.5V to 200V. These components are mainly used for protecting circuitry from transient overvoltages due to their low energy losses and rapid switching. They can also be used for voltage clamping and linear stabilisation, as well as for voltage referencing. Typical applications for this series of diodes include AC adapters, automotive and telecoms equipment, consumer electronics, industrial equipment, and medical and military applications.

Working Principle

The CRZ27 has two main variants: TE85L,Q, and M. The ”L” and ”Q” versions have leaded package types and are relatively slow-switching at 6.5V, while the ”M” version is faster-switching, at just 4.5V. All have low dynamic resistance and a wide temperature range.

These Zener diodes work in the same principle as other Zener diodes. When forward-biased they act as a normal diode, allowing current to flow. When reverse biased, they enter a breakdown region which makes them much easier to control. This allows the voltage across them to be precisely controlled. This two-way control ability makes them a popular choice for many different circuit designs.

The technology of the CRZ27 series of diodes makes them very efficient and durable. They feature high quality silicon dies, giving them low leakage and low power losses even at high temperatures. The high sensitivity and fast switching also makes them suitable for a wide range of applications, including those in more demanding environments.

Conclusion

The CRZ27 series of single, Zener diodes are popular for their wide range of applications and their efficient and reliable operation. They are easy to control and offer high-speed switching, low dynamic resistance, low leakage and low power losses. There are three versions available, with leaded package types providing varying response speed.
