Hi,
For my project I need to add a back EMF diode to protect my MOSFETs from the back EMF from my solenoids, but I have no knowledge about deducing which diode I need (e.g. type, ratings, etc.). So I hope anyone can help me out here.
I currently have the following:
- DC power supply: 48V
- Solenoid: 50V, 133Ω, 19W@50V
- Solenoid: 50V, 3.7Ω, 675W@50V
- MOSFET: 28A, 100V, Enhancement type, logic-level, N-channel (IRL540PBF)
- Arduino: 5V
- Pull-down resistor: 10kΩ
One important detail is that the diode must influence the turn-on and release time as little as possible.
How can I chose the right diode, what search/filter parameters that I need to enter in the Mouser search, and do you have any recommendations for diodes to use here?
Thanks in advance,
Raymond
