1N4148 Small Signal Fast Switching Diode

1N4148 Small Signal Fast Switching Diode is a Common small signal fast switching diode.

Perfect for converting 5V level logic to 3.3V level compatible logic. Connect two of these diodes in series between a 5V level device and a 3.3V level device to get a voltage drop of around 1.4V, effectively converting your 5V logic level to a 3.6V logic level which is usually acceptable on 3.3V logic level devices (check the specifications of your specific device to be sure).
