PZU22BL,315

Diodes - Zener - Single

The PZU22BL,315 is a Zener single diode with a maximum rating of 8.2 Volts and a power dissipation rating of 0.25 watts. It is a 3mm Surface Mount Device, with an operating temperature range of -65°C to +125°C. Three different versions of this diode are available, which are PZU22BL-1, PZU22BL-2 and PZU22BL-3.

Application Field

The PZU22BL,315 is used in a variety of applications such as DC to DC converters, voltage regulators, voltage references, and surge suppressors. It is also used in clamping and limiting circuits, AC direct current and AC line switches, circuit breaker and as a protection diode.

Working Principle

The PZU22BL,315 is a Zener diode, which uses the reverse-bias breakdown phenomenon for its operation. The diode is designed in such a manner that it can withstand voltages up to the Zener breakdown voltage of 8.2 Volts. When a voltage greater than the Zener voltage is applied, the diode breaks down and a significant amount of current starts flowing through it. This current is called Zener current and it is responsible for maintaining the Zener voltage at a steady level, regardless of changes in the applied voltage. The diode also has negative resistance characteristics and behaves like a voltage regulator as it has the ability to maintain a voltage at a constant level.

The PZU22BL,315 Zener diode is an ideal choice for applications where a high current flow is required at a steady voltage level. It can also be used in noise suppression and EMI filtering, as it can act as a clamp for negative voltages.

In short, the PZU22BL,315 is a Zener single diode that is suitable for a wide range of applications where a steady voltage is required. It offers excellent reliability and performance at a relatively low cost.
