IR2101PBF

Gate Driver Overview

The IR2101PBF is a dual, half-bridge, high-voltage, high-speed power MOSFET and IGBT driver manufactured by Infineon Technologies. It features independent high-side and low-side drivers with a supply voltage range of 10V to 20V. The device provides peak output currents of 130mA source and 360mA sink. It operates within a temperature range of -40°C to 125°C and is housed in an 8-pin PDIP package.

Gate Driver Feature Summary

• Independent high-side and low-side channel drivers for half-bridge configurations
• High-voltage capability up to 600V for floating channel operation
• Non-inverting logic input compatibility for direct interface with control circuits

Gate Driver Applications

• Switched-mode power supplies (SMPS)
• Motor control applications using IGBTs or MOSFETs
• Power inversion circuits requiring isolated gate driving

Gate Driver Procurement Notes

Verify the specific ordering suffix and package variant against the official Infineon datasheet before procurement. Confirm that the component meets the required thermal and electrical specifications for the target application environment. Check current lifecycle status as components may be subject to change or obsolescence notices from the manufacturer.

Gate Driver Selection Notes

Select this component when a robust, high-voltage half-bridge driver is required for driving IGBTs or MOSFETs. Ensure the control logic voltage levels are compatible with the non-inverting inputs. Consider the PDIP-8 package constraints for thermal management and PCB layout space compared to surface-mount alternatives like the STRPBF variant.

Gate Driver Part Context

The IR2101 belongs to the IR21xx series of high-voltage gate drivers designed for power electronics. It serves as a foundational component for driving power switches in medium-power applications. The PBF suffix indicates a lead-free, halogen-free package compliant with RoHS standards, distinguishing it from older non-compliant variants.

Gate Driver Replacement Considerations

The IR2101STRPBF is a pin-compatible surface-mount alternative offering identical electrical performance in an SOIC-8 package. Designers must adjust PCB footprint and reflow soldering profiles when substituting the DIP version with the SMD variant.
