Introduction

TVS (Transient Voltage Suppressors) are semiconductor devices designed to protect sensitive electrical components from damage due to overvoltage transients. The SA150-E3/73 is a TVS Diode that has been designed to offer a robust level of protection against surges, spikes, and other forms of overvoltage transients. In this article, we will look at the application fields and working principles of the SA150-E3/73.

Application Fields

The SA150-E3/73 is commonly used in a wide variety of applications, including:

• Telecommunications - to protect against lightning surges and other high-voltage transients.
• Industrial Control Systems - to protect against power surges and voltage spikes.
• Network Protection - to protect against power surges and voltage spikes.
• Automotive - to protect against voltage overshoot and other overvoltage transients.

The SA150-E3/73 is also suitable for a wide range of other applications, including the protection of audio and video equipment, locomotive control systems, and other similar consumer and industrial applications.

Working Principle

The SA150-E3/73 works on the principle of a breakdown voltage. When the applied voltage exceeds the breakdown voltage threshold of the device, the device will rapidly dissipate the excess voltage in the form of a surge-current, thus protecting the circuit from damage.The SA150-E3/73 has a peak pulse current rating of 1,500A (10/1000µs) and a peak power rating of 350W. The breakdown voltage of the device is typically VBR ≈ 35V (stand-off voltage) and it can operate over a wide temperature range (-55°C to 125°C).The device is rated for a variety of surge current levels, and is also designed to be bidirectional, meaning that it can protect both positive and negative voltage transients on the power line.

Conclusion

As can be seen from this article, the SA150-E3/73 is a TVS Diode designed to provide robust protection against overvoltage transients. It has a wide variety of application fields, and is suitable for a range of protection requirements. The device works on the principle of a breakdown voltage, and is rated for a variety of surge current levels.
