IR2111STR

Gate Driver Overview

The IR2111STR is a high-voltage, fast power MOSFET and IGBT driver IC manufactured by Infineon Technologies. It features a 600 V half-bridge topology with junction isolation for level shifting. The device provides a peak output current of 0.25 A source and 0.5 A sink. It operates within a supply voltage range of 10 V to 20 V. Key timing parameters include a maximum turn-on propagation delay of 750 ns and a turn-off delay of 150 ns. Rise and fall times are specified at 130 ns and 65 ns respectively. The component is housed in an 8-pin SOIC package and supports an operating temperature range from -40°C to +125°C.

Gate Driver Feature Summary

• DC-to-AC inverters

Gate Driver Procurement Notes

Verify the specific suffix 'STR' corresponds to the tape-and-reel packaging variant rather than the tube-packaged 'SPBF' version. Confirm that the leaded status aligns with project requirements, as some variants may not be fully RoHS compliant. Ensure the supplier documentation explicitly references the Infineon datasheet for the IR2111 series to validate electrical characteristics against counterfeit components.

Gate Driver Selection Notes

Select this component when a robust half-bridge driver with integrated bootstrap functionality is required for voltages up to 600 V. The choice depends on the need for a single-channel solution driving both high-side and low-side switches. Consider the propagation delays and output current capabilities relative to the target MOSFET or IGBT gate charge requirements.
