IGBTs are generally preferred for applications above 600V where the low conduction loss of a bipolar device outweighs the switching speed advantages of a MOSFET.
Transistors - IGBTs - Single Component Intelligence
High-efficiency power switching for industrial and automotive applications.
What are Transistors - IGBTs - Single components?
Single IGBTs are the standard for high-voltage, high-current switching (typically >600V). They offer the high input impedance of a MOSFET with the low conduction loss of a BJT. Select based on Vces, Ic, and switching frequency to balance thermal and efficiency targets.
How to Choose Transistors - IGBTs - Single Components
Selecting the right IGBT requires balancing switching speed against conduction losses.
Vces Rating
Ensure the collector-emitter breakdown voltage provides sufficient headroom for your bus voltage, including transient spikes.
Saturation Voltage (Vce(sat))
Lower Vce(sat) reduces conduction losses, critical for high-current, low-frequency applications.
Switching Frequency
Match the device's switching speed to your PWM frequency to minimize switching losses and thermal stress.
Gate Charge (Qg)
Lower gate charge allows for faster switching and reduces the requirements for the gate driver circuit.
Thermal Management
Evaluate the package's thermal resistance (Rthjc) and ensure it can dissipate the calculated power loss in your ambient environment.
