The PDZVTR27B (27V Zener diode) is a diode that is part of the Single Zener Diode family. It is a semiconductor device that regulates the voltage flow between two points and is used primarily in low voltage applications such as digital logic, signal conditioning, data acquisition, and communication systems. The PDZVTR27B is designed to provide a stable voltage over a wide range of operating conditions, even in environments with high levels of noise or interference.

Application Field

The PDZVTR27B diode is designed primarily for AC and DC power conversion, as well as for EMC protection. These diodes are ideal for use in:

• DC-DC converters
• DC-AC converters
• Power supplies
• Power factor correction
• Passive pulse-shaping filters
• Lighting systems
• Heaters, motors and other home appliances

The PDZVTR27B diode is also suitable for use in communications systems, audio equipment and medical equipment.

Working Principle

Zener diodes provide a stable voltage over a wide range of operating conditions, even in environments with high levels of noise or interference. This is achieved by the interaction of the opposing P- and N-type semiconductor materials. When a forward bias is applied, current flows through the device, and when a reverse bias is applied, the current stops flowing due to the change in resistance.

When a reverse bias voltage is applied, the current flow is limited due to a reduction in the majority carrier concentration and an increase in minority carrier concentration, allowing the device to act as a voltage regulator. The PDZVTR27B has a reverse breakdown voltage of 27V and a maximum power dissipation of 500mW.

The PDZVTR27B also has a low dynamic resistance and low leakage current, as well as a wide operating temperature range of -40°C to +130°C. This makes it ideal for applications in which precise and stable voltage regulation is required in harsh environments.
