Another Marking Code For 1n4148 Signal Diode

Don't be surprise to see a different code for 1n4148 signal diode. It marked only 48 and you could not see full part number which is the 1N4148. Do not think also that it is a 48 volt diode. Not all equipments are using this different code but if you come across a diode that mark '48' then automatically you have to know it is a 1n4148 diode!
