Diodes have been used in consumer and industrial applications for decades, and the BZD27B22P-HE3-08 Zener single diode is no exception. This diode offers reliable performance and high tolerance levels over a wide range of operating conditions. It is ideal for applications such as linear voltage regulation and EMI suppression.

Characteristics

The BZD27B22P-HE3-08 Zener single diode offers a variety of key characteristics including a maximum working voltage of 5.6V and a nominal Zener voltage of 4.7V. It is also capable of withstanding a very high surge current at 1mA for a repetition rate of 10x/s or 1ms. In terms of operating temperature, the rated operating temperature range for the diode is between -65 degrees Celsius and +175 degrees Celsius.

Package and Aging Behaviour

The BZD27B22P-HE3-08 Zener single diode is delivered in a TO-236 coil package, which provides excellent electrical performance and protection from mechanical and electrical disturbances. Additionally, the TO-236 package provides a high level of support against aging behaviour as it provides a controlled environment for the diode to operate in.

Application Field

The BZD27B22P-HE3-08 Zener single diode is ideally suited for a range of applications, such as rectification, linear voltage regulation, and EMI suppression. The diode is also suitable for use in low-voltage circuits as it has a very low forward voltage drop ratio. The forward voltage ratio is equal to the reverse voltage ratio. As such, power loss is minimized in applications involving a low supply voltage.

Working Principle

The BZD27B22P-HE3-08 Zener single diode works on the principle of Zener breakdown. Zener breakdown is a process in which a high electric field across the diode is achieved due to the increased electric field at the junction. When the electric field exceeded a certain value, the diode begins to break down, resulting in a large amount of current flow. The diode then acts as a voltage regulator, with the breakdown voltage defining the voltage at which it operates.

Safety Considerations

In addition to providing reliable performance, the BZD27B22P-HE3-08 Zener single diode has several safety considerations in place. To avoid damage from high reverse voltage, the forward current should never exceed the maximum peak surge current specified by the manufacturer. Additionally, the diode should be operated below its maximum working temperature, as it could be damaged if it is operated beyond these limits.

Conclusion

The BZD27B22P-HE3-08 Zener single diode is a reliable and efficient component designed for applications with a low supply voltage. It features a low forward voltage ratio, a high surge current rating and a wide operating temperature range. Additionally, it is also designed to withstand aging behaviour. It is well suited to a variety of applications, such as rectification, linear voltage regulation, and EMI suppression. As such, it is an ideal component for engineers and technicians looking to build or maintain circuits with a low supply voltage.
