SAC15-E3/54 Circuit Protection

TVS-diodes are a form of protection device, which blocks overvoltage due to external sources. Conventionally diodes are used for protection, but they do not have the capacity to block large transients. That is why transient voltage suppression (TVS) diodes are often used in many electronic systems.

SAC15-E3/54 is a form of popular TVS diode, which is utilised in protecting battery systems, telecommunication systems and other overvoltage conditions. This TVS diode has voltage breakdown of 44.4V and peak pulse power of 15W.

Specifically, the SAC15-E3/54 TVS Diode devotes itself to precision electronic assemblies such as automotive systems, telecoms boards,and manufacturing equipments. Also, automotive applications such as run flat systems, airbag systems, and alarms rely heavily on SAC15-E3/54s for high-efficiency overvoltage protection. The device is able to manage relatively high voltage and current surges, making it suitable for use in DC/DC converters, where high frequencies and narrow pulse duration require a diode with rapid response time and low clamping parameters. Furthermore, its application can be seen in many industry sectors, such as automotive, white goods, hand-held devices, and PC / peripheral circuits.

The basic working principle of a TVS diode is relatively simple. When the voltage across the diode exceeds its specified breakdown voltage, the device starts to conduct current. This action limits and reduces the voltage across the diode to the specified peak pulse power of the device. So the transient voltage of the system is “clamped”, and is protected from further harm.

The advantage of protecting high speed signals with TVS diodes over other types of active or passive components is their fast response time. They are able to control voltage transients in less than 1ns, which provides effective protection from the damaging effects of overvoltage. The SAC15-E3/54 TVS diode features a working temperature range of –40°C to +125°C. It consist of a zinc oxide element that helps achieve fast responding time, great temperature stability and energy capacity.

In conclusion, SAC15-E3/54 TVS diode is an effective device for controlling overvoltage conditions and protecting important electronic assemblies. Its fast response time and wide operating temperature range make it suitable for use in many protection applications. Furthermore, its robust construction and low clamping voltage ensures system reliability.
