IRS2128STRPBF

Gate Driver Overview

The IRS2128STRPBF is a single-channel high-side gate driver manufactured by Infineon Technologies, designed for driving IGBT and N-Channel MOSFET devices. It operates within a supply voltage range of 10 V to 20 V and delivers an output current of 200 mA. The device features fast switching characteristics with rise and fall times of 80 ns and 40 ns, respectively. Maximum delay times are specified at 200 ns for turn-off and 250 ns for turn-on. It functions reliably across an extended temperature range from -40°C to +125°C and consumes a typical operating supply current of 120 µA.

Gate Driver Feature Summary

• Provides high-side gate drive capability for power switching applications
• Compatible with standard CMOS and TTL logic input levels
• Designed for robust operation in industrial and automotive environments

Gate Driver Applications

• Driving IGBT modules in motor control systems

Gate Driver Procurement Notes

Verify the component authenticity through authorized distributors or direct manufacturer channels. Confirm that the part matches the specific suffix STRPBF for tape-and-reel packaging. Ensure compliance with RoHS directives if required for your assembly process. Check for moisture sensitivity handling requirements during storage and reflow soldering procedures.

Gate Driver Selection Notes

Select this driver when a single high-side channel is sufficient for the application. Consider the SOIC-8 package constraints for PCB layout space. Evaluate the 200 mA output current against the gate charge requirements of the target power device. Verify that the input logic levels align with the controlling microcontroller or DSP signals.

Gate Driver Part Context

This component belongs to the IR212x family of gate drivers from Infineon Technologies. It shares functional similarities with the IR2128SPBF but differs in packaging format. The series is widely used in power electronics for its reliability and ease of integration into half-bridge configurations.

Gate Driver Replacement Considerations

The IR2128SPBF is a pin-compatible alternative available in tube packaging. Verify that the change in packaging does not impact automated assembly processes. No other direct substitutes are confirmed in public documentation.
