SMAJ28C-E3/61

The SMAJ28C-E3/61 is a device belonging to the Transient Voltage Suppression (TVS) diode family, and is used to protect electrical and electronic components from transients caused by electrostatic discharge (ESD), electrical overstress (EOS) and lightning surges. This diode is designed to absorb high-powered transients and to provide robust high-voltage protection for a wide range of applications in the consumer electronics, industrial, automotive and telecommunication sectors.

The SMAJ28C-E3/61 is based on the principle that it has two closely coupled, but electrically isolated PN junction diodes which are connected in series in order to provide a higher voltage protection. When the transient voltage exceeds the breakdown voltage of one of these diodes, the second diode begins to conduct also to form a low-resistance path for the applied surge. This effectively clips the peak of the transient voltage to the breakdown voltage of the two diodes in series, thus providing effective protection.

Some of the most common applications for the SMAJ28C-E3/61 include computer and peripheral equipment protection, AC-power supply line protection, modem and lighted display protection, lightning- and surge-protection, and automotive electronics protection. In consumer electronics, it is routinely used to provide surge protection in consumer electronic equipment such as laptops, cell phones and portable music players. In the automotive industry, it is used in sensors and control systems to protect against voltage spikes due to EMI and ESD.

The SMAJ28C-E3/61 is a robust device that can withstand up to a peak pulse current of 28A, with a maximum repetitive peak reverse voltage rating of 61V. It is designed to allow a relatively low clamping voltage to protect the protected component from overvoltage transients, with very fast response time to suppress very fast transients while providing excellent clamping characteristics. It is also designed with a low dynamic resistance to reduce the amount of ringback effect which can be caused by voltage overshoots after the device has been triggered.

The SMAJ28C-E3/61 offers excellent protection for a wide variety of components and systems. It is a cost effective solution for providing robust, reliable high-voltage protection from transients in consumer electronics, industrial, automotive and telecommunication sectors. It offers a peak surge current rating of 28A, a maximum repetitive peak reverse voltage rating of 61V and a low dynamic resistance for fast response times. Additionally, the SMAJ28C-E3/61 has a wide operating temperature range, making it suitable for a variety of applications.
