PMBT3904 NPN General Purpose Transistor SMD SOT-23 Dual Operational Transconductance Amplifiers With Linearizing Diodes and Buffers With an ergonomic hexagonal housingPMBT3904 is a general purpose semiconductor device that may be used to amplify, switch, or control a signal or power. Because the PMBT3904 is an NPN transistor, we must apply a little amount of positive voltage to the transistor's base via a current limiting resistor known as an RB (Base Resistor). When the proper amount of current passes through the transistor's base, the transistor will switch on. The PMBT3904 NPN transistor is packaged in a tiny
