TVS - Diodes
A transient voltage surge suppressor (TVS) diode is an electrical component, which is designed to quickly and efficiently protect a device or circuit from damage due to high voltage and power surges. The SMA6J40A-TR TVS diode is used to protect power supply lines, communication ports, and other sensitive components or systems from voltage and power surges. In this article, we will discuss the application field and working principle of the SMA6J40A-TR.
Application Field
The SMA6J40A-TR is well suited for applications requiring fast response time and excellent capability of holding off high voltage. It can be used for components in automotive, industrial, computer, communication and home appliance applications. The SMA6J40A-TR is also widely used to protect power supply lines, communication ports, and other sensitive components or systems from voltage and power surges.
Working Principle
The SMA6J40A-TR is composed of two components: an N-channel MOSFET and a fast-acting avalanche diode. When a high voltage surge occurs, the voltage breakdown in the avalanche diode will activate the MOSFET, causing the current to be blocked. This effectively prevents the surge from damaging the protected component or system. The SMA6J40A-TR uses a low on-resistance of 0.025Ω, which allows it to conduct high-current surges, such as those caused by defibrillators or lightning, without suffering damage. The SMA6J40A-TR also provides an excellent ability to hold off high voltage, with a maximum clamping voltage of 5.5V.
Conclusion
The SMA6J40A-TR is a fast-acting TVS diode designed for effective protection of power supply lines, communication ports, and other sensitive components or systems from voltage and power surges. Its low on-resistance and high voltage holding off capability make it an ideal choice for applications in automotive, industrial, computer, communication, and home appliance fields.
