Web1. There are plenty of ways, Here's two: -. Note the diode across the motor - this is needed to protect the BJT (or MOSFET) when the transistor is switched-off - this circuit will be OK for low-power fans. Rate the transistor in accordance with the current the fan needs. WebJan 11, 2024 · To calculate the base resistor, subtract the B-E 0.7V from the driver voltage and divide by the base current: 4.5-0.7 = 3.8V / 400uA = ~9.5K ohms max. The difference in CE drop between a factor of ten and using the beta is neglible for relatively slow on/off circuits, and it lowers the driver current requirement.

WebWhen an IGBT is used as controlled switch in a static state, its current and voltage ratings equal to that of BJT. On the contrary, the isolated gate in IGBT makes it easier to drive BJT charges and hence less power is required. IGBT is switched ON or OFF based on whether its gate terminal has been activated or deactivated. WebApr 5, 2024 · Views today: 3.11k. Bipolar junction transistor (BJT) is the type of transistor and three-terminal semiconductor device, which has two p-n junctions. They are mainly used as amplifiers or current controlled devices in electronic circuits. Both the electrons and holes will act as the charge carriers in the Bipolar junction transistor.

WebOff or Cutoff Mode. This mode is the opposite of saturation. The transistor essentially resembles a broken or open circuit; no collector current is allowed to flow, and so there is no emitter current output. When driven into either cutoff or saturation mode, the BJT effectively functions more like a binary (on/off) circuit switch.
