Relay Coil Reverse Voltage at Gina Powell blog

Relay Coil Reverse Voltage. Normally a designer puts in plenty of reserve in the reverse rating. a common solution for suppressing relay coil bemf is to place a general purpose diode across the coil to serve as a shunt. The use of a flyback diode in a relay circuit prevents huge voltage spikes from arising when the power supply is disconnected. a high reverse voltage causes a large current to flow through the circuit, which damages the contact that controls power supply to. counter electromotive voltage generated when the coil voltage of a relay is interrupted causes overvoltage to various. the diode reverse voltage rating should be at least the voltage applied to the relay coil. when the relay is closed, there is a surge of current, and the applied voltage drives the diode into reverse bias. a flyback diode is placed with reverse polarity from the power supply and in parallel to the relay’s inductance coil.
