IR2112STR Equivalent & Substitute Parts

Part Overview

The IR2112STR is a high-side or low-side gate driver IC manufactured by Infineon Technologies, designed for driving IGBT and N-Channel MOSFET gates in power management applications. This component operates with independent dual-channel configuration and supports bootstrap voltage up to 600V. The IR2112STR is currently classified as obsolete, making equivalent substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2112STR is determined by strict equivalence across the following critical parameters:

• Driven configuration (high-side or low-side capability)
• Channel type and number of independent drivers
• Gate type compatibility (IGBT and N-Channel MOSFET support)
• Supply voltage range (10V ~ 20V)
• Logic voltage thresholds (VIL 6V, VIH 9.5V)
• Peak output current specifications (250mA source, 500mA sink)
• Bootstrap voltage rating (600V maximum)
• Rise and fall time characteristics (80ns rise, 40ns fall)
• Operating temperature range (-40°C ~ 150°C)
• Package form factor (16-SOIC)

The IR2112STRPBF meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and compliance certification, not functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The IR2112STRPBF is the direct substitute for the obsolete IR2112STR. Both parts are manufactured by Infineon Technologies and share identical electrical and functional specifications across all critical parameters.

Selection between these parts should be based on the following factors:

• Product availability: IR2112STR is obsolete; IR2112STRPBF is active and maintains higher inventory levels (17,230 pcs vs. 1,532 pcs).
• Regulatory compliance: IR2112STRPBF meets ROHS3 compliance requirements, while IR2112STR does not. For applications subject to RoHS regulations, IR2112STRPBF is the required choice.
• Moisture handling: IR2112STRPBF has MSL 3 rating (168 hours), requiring controlled storage conditions. IR2112STR has MSL 1 (unlimited) rating. Storage and handling procedures must align with the selected part's MSL classification.
• Packaging options: IR2112STRPBF is available in Cut Tape (CT) and Digi-Reel® packaging, providing flexibility for different procurement and assembly workflows.

For new designs and ongoing production, IR2112STRPBF is the appropriate selection due to active product status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can IR2112STRPBF directly replace IR2112STR in existing designs?

A: Yes. Both parts are electrically and functionally identical across all specified parameters. No circuit modifications are required for substitution. Pin configuration, package footprint, and electrical characteristics are identical.

Q: What is the difference between IR2112STR and IR2112STRPBF?

A: The parts are functionally equivalent. The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and moisture sensitivity level (MSL 1 vs. MSL 3). Electrical performance and specifications are identical.

Q: Are there any compatibility concerns when switching from IR2112STR to IR2112STRPBF?

A: No compatibility concerns exist. Both parts use the same 16-SOIC package, have identical pin assignments, and meet the same electrical specifications. PCB layout and component placement remain unchanged.

Q: What does MSL 3 (168 Hours) mean for IR2112STRPBF?

A: MSL 3 indicates the part must be stored in controlled humidity conditions and has a floor life of 168 hours after exposure to ambient conditions. After this period, the component must be baked before reflow soldering. Proper storage in dry-pack conditions is required.

Q: Why is IR2112STR listed as obsolete?

A: IR2112STR has been discontinued by Infineon Technologies. IR2112STRPBF is the active replacement part that maintains the same functionality and specifications.

Q: Can I use IR2112STRPBF in applications requiring RoHS compliance?

A: Yes. IR2112STRPBF is ROHS3 compliant and meets RoHS regulatory requirements. IR2112STR is not RoHS compliant and cannot be used in applications with RoHS mandates.

Q: What packaging options are available for IR2112STRPBF?

A: IR2112STRPBF is available in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both manual and automated assembly workflows.
