IR2111STR Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IR2111STR is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for driving IGBT and N-Channel MOSFET configurations in power management applications. This non-inverting gate driver operates with a supply voltage range of 10V to 20V and supports a maximum bootstrap voltage of 600V, making it suitable for synchronous half-bridge topologies.

The IR2111STR is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement. Active alternatives with identical electrical and mechanical specifications are available to ensure continuity in production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2111STR is determined by strict equivalence across all electrical and mechanical parameters. The substitute part IR2111STRPBF maintains identical specifications for driven configuration, channel type, number of drivers, gate type, supply voltage, logic voltage levels, peak output current ratings, input type, bootstrap voltage rating, rise/fall times, operating temperature range, and package dimensions.

The primary distinction between the main part and substitute is the packaging format and product status. The IR2111STR is supplied in standard packaging (product status: obsolete), while IR2111STRPBF is supplied in Tape & Reel format (product status: active). Both parts share the same base product number IR2111 and are manufactured by Infineon Technologies.

Substitution is valid when the following parameters are maintained:

• Half-bridge driven configuration with synchronous channel type
• Dual-driver architecture for IGBT and N-Channel MOSFET gate control
• Supply voltage range 10V to 20V
• Non-inverting input logic
• 600V maximum bootstrap voltage rating
• 8-SOIC surface mount package with 3.90mm width

Parameter Comparison

Engineering Selection Recommendations

The IR2111STRPBF is the direct active substitute for the obsolete IR2111STR. Both parts maintain electrical and mechanical equivalence across all specified parameters, ensuring pin-compatible and functionally identical operation in half-bridge gate driver applications.

Selection between these parts is determined by product availability and compliance requirements. The IR2111STR, classified as obsolete, is no longer recommended for new designs. The IR2111STRPBF, with active product status, is the preferred selection for ongoing procurement and new applications.

The IR2111STRPBF offers improved compliance status, meeting ROHS3 requirements compared to the non-compliant RoHS status of the IR2111STR. Both parts maintain REACH unaffected status and EAR99 export classification. The moisture sensitivity level difference (MSL 1 versus MSL 2) reflects standard industry variations in packaging handling requirements, with the IR2111STRPBF requiring one-year storage compliance.

For applications requiring RoHS3 compliance or new production designs, IR2111STRPBF is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part provides equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can IR2111STRPBF directly replace IR2111STR in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. Pin configuration, electrical characteristics, and package dimensions are identical. The primary difference is product status and packaging format (Tape & Reel versus standard packaging).

Q: What is the difference between IR2111STR and IR2111STRPBF?

A: The parts are functionally identical. IR2111STR is obsolete and supplied in standard packaging. IR2111STRPBF is active and supplied in Tape & Reel format. IR2111STRPBF also meets ROHS3 compliance, while IR2111STR does not.

Q: Are there any pin configuration differences between these parts?

A: No. Both parts use the 8-SOIC package with identical pin assignments and electrical connections. They are direct pin-for-pin equivalents.

Q: What is the significance of the Tape & Reel packaging format?

A: Tape & Reel packaging is standard for automated assembly processes and high-volume production. It provides improved handling efficiency and is the preferred format for modern manufacturing. Standard packaging is typically used for lower-volume or legacy applications.

Q: Does the moisture sensitivity level difference affect compatibility?

A: No. Both MSL 1 (unlimited) and MSL 2 (1 year) ratings indicate low moisture sensitivity. The difference reflects standard packaging variations. MSL 2 requires adherence to one-year storage and handling protocols, which are standard industry practice.

Q: Is IR2111STRPBF suitable for new designs?

A: Yes. IR2111STRPBF is the active product and is recommended for all new designs. It provides equivalent electrical performance with improved compliance status (ROHS3).

Q: What applications are these gate driver ICs suitable for?

A: These half-bridge gate drivers are designed for IGBT and N-Channel MOSFET switching applications, including power conversion, motor control, and synchronous rectification circuits operating within the specified 10V to 20V supply voltage range and 600V bootstrap voltage rating.
