TVS - Diodes, such as SMDJ26C, are protection components designed to protect circuits against transients and surge currents caused by lightning strikes, system faults, and other sources. The portection afforded by TVS diodes is realized through their ability to clamp voltage surges quickly and with minimal voltage drop.

The SMDJ26C’s construction consists of two basic elements, an input diode and the pair of avalanche breakdown diodes. The avalanche diodes are used to limit voltage overshoots beyond the prescribed voltage level of the component, depending on the diode voltage handling capability.

The TVS diode behaves as a closed switch when its reverse breakdown voltage is exceeded and as an open switch when reverse current flows. This ensures a high level of protection against overvoltage transients, while having an extremely low leakage current during normal operation. During a fault condition, the TVS diode will react instantly by clamping the voltage and then diverting most of the surge current to the ground.

The SMDJ26C is especially useful in applications requiring high-speed switching of voltage and current, such as those found in power supplies and automotive electronics. Thanks to its high surge current handling capability and low holding voltage, it is ideal for protecting sensitive circuitry. The SMDJ26C is also suitable for protecting against overvoltage transients caused by electrostatic discharges (ESDs).

In summary, the SMDJ26C TVS diode is an ideal solution for protecting circuits from transients and surge currents. Its high surge current handling capability, low leakage current, low holding voltage, and fast response time make the SMDJ26C the perfect choice for a variety of applications requiring voltage and current switching. Its ability to effectively handle ESDs also makes it a great choice for protecting sensitive circuitry.
