TVS (transient voltage suppressors) are used for protecting electronic circuits from destruction, degradation or malfunction due to different types of power surges. These usually include voltage transients like lightning, electrostatic discharge (ESD), inductive load switching, and other various high-energy impulsive transients. SMDJ90 is a series of TVS diodes that have similar characteristics which make them ideal for various protection applications in different non-automotive environments.

The SMDJ90 series features a 75V standoff voltage, making it suitable for a wide range of protection applications. It has excellent clamping capability and low leakage current. The part is available in unidirectional and bidirectional configurations with 5 different lead form options. Additionally, it offers a range of packaging options such as thru-hole, SMD, and DO-214AB (SMC). The bidirectional diodes in this series can provide protection to both positive and negative power signals, and can handle high peak current levels quickly.

The working principle of the SMDJ90 TVS diode is simple but effective. It acts like a short circuit when the voltage level exceeds the rated Clamping Voltage (VC). This stops further current from flowing and diverts the surge current from the protected device, thus preventing damage to it. When the voltage across the diode falls back to the rated VC or lower, the diode reverts back to its normal state.

This TVS diode series is ideal for various non-automotive protection applications including personal computers, networking equipment, consumer electronics, telecom and wireless devices, and more. It is also an excellent choice for medical equipment and other high-reliability applications where maximum protection and failure analysis is required. It is also widely used in applications which demand robust and cost-effective protection against ESD, lightning, and other transient threats.

In summary, SMDJ90 series of TVS diodes offer excellent performance against transient voltage surges and other high-energy impulses. They have a wide range of applications and features like low leakage current, high peak current handling capabilities, and different packaging options. It is a reliable and cost-effective solution for a variety of transient protection applications.
