- Flyback Diode for 24V DC Solenoid - Electrical Engineering Stack Exchange
You are right in your assumption that the initial current in the diode will be equal to the coil current Using a diode in this fashion will cause the magnetic field to collapse more slowly and reduce the "off" response time, because the diode provides a current path for the coil
- 24V DC Contactor Coil - Flyback Diode Required - All About Circuits
The small DIN mounted type from Phoenix are 7mm wide, comes complete with LED and flyback diode and can handle the current drawn by multiple contactor coils Why risk a EUR400 part when a EUR7 part provides protection and removes the requirement for the diode
- Flyback diode selection - Page 1 - EEVblog
If you don't PWM and only switch rarely (e g , every second or minute), then average dissipation by the diode is small and it will see 6 5A only for some sub-millisecond or so, so a surprisingly small diode does fine, something like rated to 2-3A continuous current
- Flyback Diode Explained: Taming Inductor Spikes (Simple Guide)
To protect the switch from being damaged due voltage spikes or inductive Flyback, a Flyback Diode or a Freewheeling Diode is used The basic idea behind the use of a Flyback Diode is to provide an alternative path for the inductor for its current to flow
- How to choose a flyback diode for a relay? - Electrical Engineering . . .
A diode is put in parallel with a relay coil (with opposite polarity) to prevent damage to other components when the relay is turned off Here's an example schematic I found online:
- HCF60规格书_带电流承载曲线-V03 - HIITIO
It is recommended to install a non-linear resistor(Variable resistors are preferred with over 1J maximum energy tolerance and 1 5-2 times of rated voltage)to suppress the reverse electromotive force generating from the contactor coil
- Flyback diode – What is it used for? How does it work?
It is also a simple P-N junction diode that is used to protect the circuit from the flyback voltage generated by the inductive load The high voltage spike generated by the inductor due to sudden switching is called flyback voltage
