UNIT VRRM … I need the full range from an LM34DZ, but I don't have an 1N914 diode. or Cancel. As the most common mass-produced switching diode, the 1N4148 replaced the older 1N914. The black band at one end of the 1N4148 diode indicates the cathode (negative side). (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. 1N914A, 1N914B, 1N916, 1N916A, 1N916B, 1N4448, with fairly subtle between!
