Figure 2: 2N3904 circuit example - drawn in Scheme-it®. Since the 2N3904 is an NPN transistor, that means the base needs positive biasing (appropriate voltage levels and resistance) to turn on the collector emitter junction for proper current flow. dot matrix character lcd module user’s manual optrex corporation ... dmc-16188 16 x 1 5 x 8 1/8 led 151.0 x 40.0 x 14.2 reflective & el 151.0 x 40.0 x 10.0 Silicon NPN Power Transistors Silicon NPN power transistors are for use in power amplifier and switching circuits − excellent safe area limits.
