hi, i have a SCR which is 2N5062. From the datasheet i know that it is a 0.8Amp RMS 100V SCR. From the picture above, my transformer rating is 12-0-12 1A. And the fuse rating is 1A. After the 7805 i put 1k resistor and a led as a load. SCR i'm using is 2N5062 and zenor diode is 1N5339B. When i turn on the power the SCR will blow. But when i change the fuse rating to 500mA the fuse will not blow and the led will on. Can someone explain this for me? thank you.
