Hello
The 1N5400 series diodes have 200A IFSM's for a diam of ony 5,3mm. Is there a better diode to resist a short circuit when size is a premium. I'll have to give you more info.
The attached image is of a small circuit to fix inside a wall-mounted on/off switch, with the LED protruding through a hole in the face plate. When current flows the LED lights so I know when I've left a small several hundred watt blower on in the attic.
I tested with 1N4007's but when I made a short-circuit (Murphy's Law) they obviously expired before the 2A electromagnetic bipolar circuit breaker tripped.
Rather surprisingly it worked with 1N4007's running a 1.5kW vacuum cleaner even without a resistor to protect the LED.
Thanks
