Diodes - Zener - Single are semiconductor devices used to regulate voltage. A single Zener diode can be used to protect circuits from a high voltage input, by providing a controlled low voltage output. The most common application of Zener diodes is to protect circuits from overvoltage. The UDZSTE-174.3B is a single Zener diode manufactured by United Diode Corporation. It is a 2.7V 2 Watt type, with a maximum power dissipation of 5 Watts.

The UDZSTE-174.3B is packaged in a DO-35 Glass Package with a size of 2.2mm x 3.0mm. The package is designed to allow the Zener diode to dissipate heat away from the circuit board to prevent the device from overheating. The device has an operating temperature range of -65°C to 150°C and a storage temperature range of -65°C to 200°C. The device is RoHS compliant.

The UDZSTE-174.3B has a breakdown voltage of 2.7V, with a tolerance of 5% minimum, and a maximum voltage of 5.0V with a tolerance of 5%. This allows the device to provide a controlled low voltage output in situations with high voltage input. The Zener diode also has a maximum reverse current of 5mA. This protects the device from current surges and helps to keep the voltage constant.

The UDZSTE-174.3B is mainly used for transient over-voltage protection and in applications where large current surges are expected. It is typically used in power supplies and industrial equipment. The device can also be used in systems that require a high amount of current, as it can handle the maximum load of 5 Watts. Additionally, the device’s low static power consumption makes it suitable for use in energy efficient applications.

The working principle of the UDZSTE-174.3B is similar to that of other Zener diodes. When the voltage across the Zener diode is greater than the Zener voltage, it conducts current in the reverse direction. This current is limited by the maximum reverse current of the device, which helps to limit the voltage across the device to the Zener voltage. This limits the voltage to the desired level, protecting the circuit from overvoltage.

In summary, the UDZSTE-174.3B is a single Zener diode made by United Diode Corporation with a voltage of 2.7V and a power rating of 5 Watts. It is mainly used for transient over-voltage protection and in high current applications. The device’s low power consumption and temperature range make it suitable for energy efficient applications. The working principle of the device is similar to that of other Zener diodes, where the device conducts current in the reverse direction and limits the output voltage to the Zener voltage.
