With a single diode, the power is "off" for half of the AC cycle which means you get more ripple (or you have to use a bigger capacitor) and you can only get half the current. Diodes that can handle large current and voltages are known as power diodes. It can pass up to 1A and has a max. But if … The main difference between both are the switching speed. 100 pcs Rectifier Diode Tape kit,1N4148 1N4007 1N5819 1N5399 FR107 FR207 1N5408 1N5822. Heyy guys, i was asked in my electronic class to do a lab using 1N4148 or 1N914 diode, but i only have 1N4007 diode. Why don't libraries smell like bookstores? (1N914 is an identical device to the 1N4148) They will do exactly the same job in switch and lamp matrixes for pinball BUT the 4004/7 is a much tougher device and will withstand the shaking and bashing a lot better than the more fragile glass bodied diode.
