IR2011STR Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The IR2011STR is a high-side or low-side gate driver IC designed for N-channel MOSFET applications in power management circuits. This inverting gate driver operates with a supply voltage range of 10V to 20V and delivers peak output currents of 1A for both source and sink configurations. The device is packaged in an 8-SOIC surface mount package with a maximum bootstrap voltage rating of 200V.

The IR2011STR is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this gate driver topology.

Substitute Part Grouping Explanation

Substitution eligibility for the IR2011STR is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Must support high-side or low-side operation
• Channel Type: Must be independent channels
• Number of Drivers: Must provide 2 independent driver channels
• Gate Type: Must be N-channel MOSFET compatible
• Voltage - Supply: Must operate within 10V to 20V range
• Logic Voltage Thresholds: VIL and VIH must match 0.7V and 2.2V specifications
• Peak Output Current: Must deliver 1A source and 1A sink capability
• Input Type: Must be inverting configuration
• Bootstrap Voltage Rating: Must support minimum 200V maximum rating
• Timing Characteristics: Rise and fall times must be compatible with 35ns and 20ns specifications
• Package: Must be 8-SOIC surface mount form factor
• Operating Temperature Range: Must support -40°C to 150°C junction temperature range

The IR2011STRPBF qualifies as a direct substitute based on complete parameter equivalence across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The IR2011STRPBF is the direct substitute for the obsolete IR2011STR. Both parts are manufactured by Infineon Technologies and maintain complete electrical and mechanical equivalence across all specified parameters.

The primary distinction between these parts is product status and compliance certification. The IR2011STR is obsolete, while the IR2011STRPBF maintains active product status with ROHS3 compliance. The IR2011STRPBF is the recommended selection for new designs and ongoing production requirements where RoHS compliance is required or preferred.

The moisture sensitivity level differs between the two parts (MSL 1 versus MSL 2), reflecting different manufacturing and storage requirements. The IR2011STRPBF requires controlled storage conditions with a one-year shelf life limitation under specified humidity conditions.

Frequently Asked Questions (FAQ)

Q: Can the IR2011STRPBF directly replace the IR2011STR in existing designs?

A: Yes. The IR2011STRPBF is electrically and mechanically equivalent to the IR2011STR. All electrical parameters, timing characteristics, voltage ratings, current capabilities, and package specifications are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between IR2011STR and IR2011STRPBF?

A: The primary differences are product status and compliance certifications. The IR2011STR is obsolete, while the IR2011STRPBF is active. The IR2011STRPBF carries ROHS3 compliance certification. Both parts are manufactured by Infineon Technologies with identical electrical specifications.

Q: Are there packaging differences between these parts?

A: Both parts use the 8-SOIC surface mount package with identical dimensions (0.154" width, 3.90mm). Packaging format differs in that IR2011STRPBF is available in Cut Tape (CT) and Digi-Reel® configurations, while the IR2011STR packaging format is not specified in the provided data.

Q: What does the "STRPBF" suffix indicate?

A: The STRPBF suffix indicates the part includes lead-free plating and RoHS compliance certification. This designation reflects manufacturing process changes implemented to meet environmental and regulatory requirements.

Q: Is the IR2011STRPBF suitable for high-temperature applications?

A: Yes. The IR2011STRPBF operates across the full temperature range of -40°C to 150°C junction temperature, supporting both industrial and high-temperature application requirements.

Q: What are the moisture sensitivity requirements for storage?

A: The IR2011STRPBF carries MSL 2 rating, requiring storage at controlled humidity levels with a one-year shelf life limitation. The IR2011STR carries MSL 1 rating with unlimited shelf life. Proper moisture control during storage and handling is required for the IR2011STRPBF to maintain device reliability.
