What is an STFI34N65M5 IGBT?

An STFI34N65M5 IGBT is an insulated-gate bipolar transistor, or IGBT, module. This type of transistor is used as an active component in regenerative circuits, power amplifiers, and electric drive systems. It is an IC (integrated circuit) containing a N-channel MOSFET and a PNP transistor that allow a quick switching of the gate-source voltage (VGS) and the drain current (Id).

Working Principle of the STFI34N65M5 IGBTs

The STFI34N65M5 uses an insulated-gate bipolar transistor (IGBT) architecture and construction. An IGBT is essentially a combination of two transistors: a P-type MOSFET and an NPN bipolar junction transistor. Both of these components work together to switch a high- or low- and controlled voltage between two points. When a voltage is applied to the gate of the IGBT, the P-type MOSFET turns on and the NPN bipolar junction transistor simultaneously turns off, allowing the voltage to flow between the collector and emitter. This process is then reversed when voltage is no longer applied at the gate. As a result, the current that flows between the collector and emitter can be controlled and switched on and off quickly and accurately.

The STFI34N65M5 IGBT is just one example of this technology in action. It is a reliable and efficient way of controlling currents in numerous applications.

In conclusion, the STFI34N65M5 IGBT is a reliable and efficient transistor that is used for numerous applications in a wide range of industries. It features fast continuous current rise/fall times and pulse current peak/recovery times as well as a soft-start function. It is ideal for switch-mode power supplies, voltage regulation, motor drives, and high-power inverter applications.
