TVS - Diodes: SM6S26A-E3/2D Application Field and Working Principle

TVS (transient voltage suppressors) diodes are indispensable components for ensuring the performance standards of electronic devices. Without them, damage from overvoltage transients, or sudden electrical spikes, can be catastrophic. SM6S26A-E3/2D is one such diode, a unidirectional TVS diode with a 600W peak pulse power.

Applications

The SM6S26A-E3/2D TVS diode has uses in a variety of electrical applications where high power handling capacity and superior overvoltage protection is required. It can be used for automotive applications including body control systems and anti-theft devices. And in the field of consumer electronics, the TVS diode is seen in electronic phone systems, washing machines, microwaves and even air conditioners.

Working Principle

The SM6S26A-E3/2D is a unidirectional TVS diode, meaning it allows current to flow in only one direction. When the voltage goes above its clamping voltage, the diode begins to conduct and effectively short out the high voltage, thus suppressing the voltage and preventing damage to the circuit. This is known as "clamping."The clamping voltage is the voltage at which the diode conducts, and for the SM6S26A-E3/2D, it is typically 7.5V for the unidirectional type. The maximum surge power is 600W peak Pulse power for the diode at 10/1000 μS wave shape. This allows it to absorb large amounts of electrical energy, even in short intervals.

Conclusion

Overall, the SM6S26A series of unidirectional TVS diodes provide a safe and reliable way to protect electronic systems and devices from destructive voltage transients. With a maximum surge power of 600W peak Pulse power and a clamping voltage of 7.5V, it provides a cost-effective use of current limiting devices across a wide range of applications from automotive to consumer electronics.
