PH4148 vs T4148 vs 1N4148 diode?

[geratheg]

I have a diode that has PH4148 written on it and one that has T4148.

What's the difference between these diodes? Are they both different from 1N4148?

Hi, They are general purpose type with no major differences. Can be small differences from manufacturer to manufacturer or from lot to lot but nothing to worried about

Thanks for the reply.

So the letters in the beginning represent manufacturer?
