IR2125PBF

Gate Driver Overview

The IR2125PBF is a high-voltage, high-speed power MOSFET and IGBT driver manufactured by Infineon Technologies. It features proprietary HVIC technology and latch-immune CMOS design for robust performance. The device includes over-current limiting protection circuitry to safeguard connected power switches. It operates with a supply voltage range of 0V to 18V and supports logic levels compatible with CMOS and TTL standards. The component is housed in an 8-pin PDIP package suitable for through-hole mounting.

Gate Driver Feature Summary

• Integrates over-current limiting protection circuitry for enhanced system reliability
• Utilizes proprietary HVIC and latch-immune CMOS technology for high noise immunity
• Designed specifically for driving high-side power MOSFETs and IGBTs

Gate Driver Applications

• High-side gate driving for power MOSFETs
• Gate driving for IGBT modules
• Industrial motor control systems requiring current protection

Gate Driver Procurement Notes

Verify the specific suffix 'PBF' confirms lead-free compliance and PDIP-8 packaging when sourcing. Confirm that the part number corresponds to the standalone high-side driver variant rather than other family members with different pinouts or protection features. Ensure compatibility with your PCB footprint specifications before finalizing procurement orders.

Gate Driver Selection Notes

Select this component when a single-channel high-side driver with integrated current limit functionality is required. It is suitable for applications needing latch-up immunity and operation with standard digital logic inputs. Consider the thermal dissipation capabilities of the DIP-8 package relative to the expected switching frequency and load conditions.

Gate Driver Part Context

This part belongs to the IR212x series of gate drivers from Infineon. It is distinct from half-bridge variants like the IR2110, offering only high-side drive capability. The PBF suffix indicates a Pb-Free (lead-free) manufacturing process compliant with RoHS directives, packaged in a standard plastic dual in-line format.

Gate Driver Replacement Considerations

Direct functional substitutes within the same Infineon lineup include the IR2125SPBF (SOIC-16 package) and IR2125STRPBF (SOIC-16 tape & reel). Verify pinout compatibility and package dimensions when considering these alternatives for board-level replacements.
