PZU3.3BL,315

Diodes- Zener– single

The PZU3.3BL,315 is a single Zener diode device manufactured by US manufacturer Vishay Intertechnology. The device is designed as a semiconductor device, which is usually marked with a broken line and/or striped end to indicate it is a Poladized Silicon Zener Diode.

Application Fields

The PZU3.3BL,315 has a variety of application fields. It is widely used as a regulator and voltage limiter for semiconductor applications. It can be used for voltage clamping for circuits, providing a stable reference voltage for analog circuits and providing a termination point for current limiting. It can also be used as a voltage divider, providing isolation for voltage regulators and as a voltage follower in an electronic circuit.

Working Principle

The PZU3.3BL,315 operates in three distinct regions of operation. In the Zener breakdown or “reverse bias” region, the PZU3.3BL,315 is designed to controll current flow and drop the voltage across a reverse-biased p-n junction. The Zener region occurs when the diode is operated in reverse bias and the voltage exceeds the Zener voltage, the breakdown voltage specified for the device. The second region, the avalanche breakdown region, occurs when the device is operated at a reverse-biased voltage that is above the avalanche breakdown voltage specified for the device and produces more current than the Zener breakdown region. The third region is the forward bias region, which is when the device operates at a voltage equal to or less than the Zener voltage and produces a low, constant value of current. In the forward bias region, the device acts as an ordinary diode.

The PZU3.3BL,315 device is designed with a maximum rated power and a maximum working voltage and current. The device is designed to allow the maximum amount of current to pass through the device, while still maintaining stability. The device has an operating temperature range of -65°C to 150°C and a maximum storage temperature of 167°C. The device exhibits excellent frequency characteristics, most notably at high frequencies, which allows these devices to be used in frequency sensitive applications.

Conclusion

The PZU3.3BL,315 is a single Zener diode device that is used for a variety of applications. It is used for voltage clamping, voltage regulation and current limiting. The device operates in three distinct regions, the Zener breakdown, avalanche breakdown and forward bias regions. The device is designed with a maximum rated power and a maximum working voltage and current and exhibits excellent frequency characteristics.
