Common Cathode Flyback Diode
Shared cathode diodes balance protection and efficiency in inductive circuits
6 hours ago
0
What is the primary trade-off when using a common cathode flyback diode in an inductive circuit?
It provides protection against voltage spikes but may introduce power losses and slower switching.
It eliminates all voltage spikes without any impact on circuit performance.
It increases voltage spikes to improve circuit response time.
