Working Principle

The GLL4749A-E3/96 diode utilizes the principle of avalanche breakdown. When a voltage is applied to the diode, a large current will flow through it. This current will cause the voltage to increase exponentially, until it reaches the diode’s breakdown voltage (also known as the zener voltage). At this point, the zener diode will allow a small current to flow through it, creating a stable voltage and preventing further increases. This allows the device to protect circuits from both overvoltage and transients.
