It can be used in various applications where its features like reverse voltage protection, bidirectional overvoltage suppression, and ESD protection make it superior to other models. It is typically used in electronic equipment that is subject to environmental extremes or surges.

Applications

The TZX27A-TR can be used in a variety of applications, including:

• Power Supply Regulation
• Lighting Control
• Industrial Controllers
• Automotive Electronics
• Computer and Networking
• Medical Devices
• Test and Measurement Equipment
• Audio and Video Equipment

The TZX27A-TR has been designed to handle the high power requirements that these applications demand. It is capable of handling power levels up to 200W and can perform in temperatures ranging from -40°C to +105°C without compromising its operation.

Working Principle

The TZX27A-TR is a bi-directional Zener diode that is designed to protect electric and electronic equipment from the damaging effects of overvoltage. It is designed so that when the voltage applied to it exceeds the breakdown voltage, it conducts a current that is proportional to the voltage in a very consistent manner.

The TZX27A-TR operates on the principle that when a potential difference is applied across it exceeding the breakdown voltage, current flows in both directions. It has a breakdown voltage of 27V and operates at over 99% efficiency. This ensures that when used in circuit designs that require bidirectional overvoltage protection, it performs its task with minimal power loss.

The TZX27A-TR also has the ability to dissipate excess energy in the form of heat. This is done through its built-in thermal protection, which keeps the device from burning out when exposed to long-term high-power levels. This allows the device to be used in high-power applications, where other overvoltage protection devices may fail.

Conclusion

The TZX27A-TR is a single Zener diode designed for general purpose applications where it provides excellent protection against overvoltage, thermal protection, and bidirectional overvoltage protection. It is capable of handling power levels up to 200W, and its temperature range makes it suitable for applications in a variety of climates and environments. Because of these features, the TZX27A-TR is a great choice for power supply regulation, lighting control, industrial controllers, automotive electronics, computer and networking, medical devices, test and measurement equipment and audio and video equipment.
