I am trying to look for a solution that can help me in turning ON/OFF my 24VDC, 2A LED load. So as per the application needs I may have to turn ON/OFF this load 30 times max per day. So it is a DC operation.
Below sketch shows a quick pictorial representation of what I am trying to do. Not a final layout yet.
I am looking if I can use a MOSFET rather electro mechanical relay. I am referring to the ROHM RQ7L050AT datasheet. This is a 60V, 5A Mosfet.
But by looking at the SOA curve as below, I am not sure if this MOSFET approach is advisable for continuous DC loads.
As per the graph, I guess at the desired 24VDC VDS the maximum allowed Id current is less than 0.07A before I hit the thermal runaway situation? (whereas my actual requirement is for 2A Id).
Let me know if I am getting if right. Can anyone help me understanding the MOSFETs for DC load operations?
Will it help if I choose higher VDS and Id rated MOSFETs?
Thanks in advance!
