#135723 - Protecting a Triac |
Hi all,
I use a simple MOC3031 and traic to control an air valve solenoid (5.4 watt). I've recently noticed that every time I have to replace the fuse, I also have to replace the triac. So I did a little investigating (searching the net) and found it is difficult to protect semiconductors from direct shorts. The recommended method is to use a I2C or 2 ms fuse, but the ones I looked at cost 5 times the price of triac, so I don't see much sense in that. Is there any other ways? Thanks Jon |
