IR2151S

Gate Driver Overview

The IR2151S is a high-voltage, fast power MOSFET and IGBT driver IC featuring a half-bridge topology with synchronous channel configuration. It supports a maximum high-side bootstrap voltage of 600 V and operates within a supply voltage range of 10 V to 20 V. The device delivers peak output currents of 125 mA (sink) and 250 mA (source). Typical rise and fall times are specified at 80 ns and 40 ns, respectively. It is designed for surface-mount installation in an 8-SOIC package and functions reliably across an operating junction temperature range of -40°C to 150°C.

Gate Driver Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm the specific orderable part number matches the required suffix and package variant. Check current lifecycle status as availability may vary. Ensure storage conditions comply with moisture sensitivity level requirements before reflow soldering. Validate that the procurement source provides valid traceability documentation.

Gate Driver Selection Notes

Select this component when a half-bridge driver with 600 V high-side capability is required. Consider the 125 mA sink and 250 mA source current ratings against gate charge requirements. Verify compatibility with the 10 V to 20 V supply range. Evaluate the 8-SOIC package constraints for PCB layout. Ensure the RC input interface aligns with the control signal generation method.

Gate Driver Part Context

The IR2151S belongs to the IR215x family of high-voltage gate drivers from Infineon Technologies. It shares architectural similarities with the IR2152S and IR2153S but differs in specific internal configurations and clamp features. This series targets applications requiring reliable isolation and fast switching speeds for power semiconductors in demanding environments.
