IR2125STR

Gate Driver Overview

The IR2125STR is a high-voltage, high-speed power MOSFET and IGBT gate driver manufactured by Infineon Technologies. It features a single-channel non-inverting input configuration housed in a 16-SOIC surface-mount package. The device supports supply voltages from 0 V to 18 V and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a maximum propagation delay of 270 ns, with rise and fall times of 43 ns and 26 ns respectively. It provides an output current capability of 1 A and includes shutdown functionality.

Gate Driver Feature Summary

• Integrates over-current limiting protection circuitry for enhanced system safety
• Features functional level-shift isolation (JI) for high-side driving applications
• Includes UVLO and fault reporting capabilities for reliable operation

Gate Driver Applications

• Driving IGBTs in industrial motor control systems
• Powering N-channel MOSFETs in high-voltage switching circuits
• High-side gate drive applications requiring current limit protection

Gate Driver Procurement Notes

Verify the specific suffix STRPBF against official Infineon documentation to confirm the tape-and-reel packaging format and RoHS compliance status. Ensure the procurement source provides valid datasheets matching the 16-SOIC pinout and electrical characteristics. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the received units match the specified operating temperature range and voltage ratings.

Gate Driver Selection Notes

Select this component when a single-channel high-side driver with integrated current limiting is required for IGBT or MOSFET applications. The 16-SOIC package suits surface-mount designs needing robust isolation. Consider the 1 A output current and 500 V blocking capability for medium-power industrial loads. Verify logic compatibility with CMOS or TTL inputs before integration into the control circuit.

Gate Driver Part Context

The IR2125 series belongs to Infineon's family of monolithic high-voltage gate drivers designed for power electronics. These devices utilize junction-isolated technology to provide functional isolation between low-voltage control logic and high-voltage power stages. The STR variant specifically denotes the surface-mount reel packaging option within the broader IR2125 product line.
