Overvoltage Protection

Electrical safety mechanisms designed to protect circuits from receiving voltages higher than their operating levels.

Zener Diodes

Semiconductor devices that allow current to flow in the forward direction like a typical diode, but can also allow it to flow in the reverse direction when the voltage is above a certain value.

Voltage Spikes

Sudden, temporary increases in voltage in an electrical circuit that can cause damage to electronic components and systems.

AC Leakage Test

A test procedure used to identify unwanted flow of current from the power lines into the grounding conductor of an electrical appliance or system.
