Suojadiodis

Suojadiodis, also known as a protection diode or suppressor diode, is a semiconductor device used to protect electronic circuits from overvoltage transients. These transients can be caused by various sources, including lightning strikes, electrostatic discharge (ESD), and switching inductive loads. A suojadiodis is typically connected in parallel with the circuit it is protecting. When the voltage across the suojadiodis exceeds its breakdown voltage, it becomes conductive and diverts the excess current away from the sensitive components. This action effectively clamps the voltage to a safe level, preventing damage.

There are several types of suojadiodis available, including Zener diodes, transient voltage suppressors (TVS diodes), and metal-oxide-varistors (MOVs). Zener diodes are commonly used for lower power applications and offer precise voltage regulation. TVS diodes are designed for faster response times and higher surge current handling capabilities. MOVs are robust and cost-effective solutions for higher energy transient suppression. The selection of the appropriate suojadiodis depends on factors such as the expected transient voltage, pulse duration, and the circuit's operating voltage. Proper implementation of suojadiodis is crucial for ensuring the reliability and longevity of electronic equipment.
