What is an IGBT?

An IGBT is a power semiconductor device that combines the gate-controlled input characteristics of a MOSFET with the low conduction loss of a bipolar transistor. It operates by using an insulated gate to control the formation of a conductive channel, which in turn enables carrier injection into the drift region to support high current flow at elevated voltages.

IGBTs are widely used in medium- to high-power conversion systems where efficient switching and high voltage blocking capability are required. Device behavior is governed by gate drive conditions, collector–emitter voltage stress, current handling capability, and thermal dissipation limits, all of which directly impact switching losses, reliability, and system efficiency.

Key Specifications

• Types: Defines the structural or functional classification of the IGBT, which determines switching behavior, conduction characteristics, and application suitability.
• Collector Emitter Voltage: Specifies the maximum voltage the device can block between the collector and emitter in the off-state, setting the upper limit for system operating voltage.
• Gate Emitter Voltage: Indicates the allowable voltage range applied between the gate and emitter terminals, influencing gate drive design and safe operating conditions.
• DC Collector Current: Represents the maximum continuous current the collector can conduct under steady-state conditions, affecting load capability and thermal performance.
• Peak Collector Current: Defines the maximum allowable collector current for short-duration events, relevant to transient operating conditions and fault tolerance.
• Power Dissipation: Specifies the maximum power the device can dissipate as heat, which is critical for thermal management and long-term reliability.
