SMFJ90-E3/52 is a kind of unidirectional transient voltage suppressors (TVS), also known as transient voltage suppression diodes. It serves various applications, including overvoltage protection, ESD and lightning protection, and surge current absorption. It’s a three-terminal, neutral, low-capacitance TVS, with a reverse standoff voltage from 12 V to 200 V.

Under normal circumstances, the SMFJ90-E3/52 device works as an open circuit. When subjected to transient overvoltages, it instantly turns on the rectifying action and acts as a short circuit to absorb the surge current and protect the circuit. When the voltage returns to normal, the device reactivates its open circuit once the reverse breakdown voltage VBR is exceeded.

The SMFJ90-E3/52 is specifically designed to be installed between the power and ground lines of sensitive circuits, in order to protect them from ESD or lightning-induced transients. It is commonly used to protect circuits which are exposed to transient voltages generated by static electricity discharge, fast transients, electrical fast transient bursts, and surge currents.

The SMFJ90-E3/52 is easily installed in systems due to its low capacitance and low leakage current. It’s highly reliable and compact compared to other standard TVS Diodes, thanks to its fast response operation, high peak pulse current, and superior surge capability. It is also available in different package options, such as SOT-23, SOT-323, SOT-457, and so on.

In conclusion, the SMFJ90-E3/52 is an excellent choice when you need superior transient protection for your sensitive applications. It offers a fast response time, great surge capability, and low leakage current and capacitance. It is highly reliable, compact, and cost-effective, and can be used in a variety of applications ranging from ESD and lightning protection, to surge current absorption.
