Transistor Switch Resistor Calculation at Jamie Heyne blog

Transistor Switch Resistor Calculation. You find this by first determining the collector current requirements of the transistor, then working backwards to find the base current, then the resistor to support the base current. Secondly, find the current gain, beta, hfe. Most of the time the transistor will be set to switch just into saturation to improve turn off time. First you must check the datasheet of the transistor in question and identify the values vbe, vce, and hfe. These values is in the datasheet for. You will find special transistors called switching transistors due to their fast rate of switching. First, calculate the current you need to pass through the transistor when its on, that is your collector current. Notice that hfe and hfe are used for. The value of the base resistor determines how much input voltage is required and corresponding base current to switch the transistor fully “on”. The spec sheets are all based on ic/ib = 10.
