IGBT
Key Features
- Hybrid Efficiency: Combines the high input impedance of a MOSFET with the low saturation voltage of a BJT.
- Superior Power Handling: Built to handle high-power loads with minimal heat generation compared to standard transistors.
- Fast Switching Speeds: Optimized for high-frequency pulse width modulation (PWM) up to 20kHz – 50kHz.
- Rugged Design: High tolerance for voltage spikes and harsh electrical environments.
- Standardized Power Packaging: Typically available in TO-247 or TO-3P cases, designed for easy mounting to large heat sinks.
