Infineon IR2301 Half-Bridge Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The Infineon IR2301 (98-0343) is a half-bridge gate driver IC designed for driving IGBT and N-Channel MOSFET configurations in power management applications. This device operates with a supply voltage range of 5V to 20V and features independent dual-channel architecture with non-inverting logic inputs. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2301 half-bridge gate driver is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Driven Configuration: Half-Bridge topology compatibility
• Number of Drivers: Dual-channel (2) independent drivers
• Gate Type: IGBT and N-Channel MOSFET support
• Voltage - Supply: 5V to 20V operating range
• Current - Peak Output: 200mA source, 350mA sink capability
• High Side Voltage - Max (Bootstrap): 600V rating
• Rise / Fall Time: 130ns rise, 50ns fall (typical)
• Operating Temperature Range: -40°C to 150°C
• Package / Case: 8-SOIC form factor
• Input Type: Non-Inverting logic configuration

The IR2301SPBF qualifies as a direct substitute based on matching all critical electrical parameters and package specifications. However, the substitute part exhibits different driven configuration capability (High-Side or Low-Side vs. Half-Bridge only) and improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

For Existing System Support: The IR2301SPBF serves as the direct electrical and mechanical substitute for the obsolete IR2301 (98-0343). All critical gate driver parameters—supply voltage, output current, bootstrap voltage, timing characteristics, and package form factor—are identical. The substitute part maintains full functional compatibility within half-bridge topologies.

Compliance Considerations: The IR2301SPBF provides improved regulatory compliance status. It is ROHS3 compliant, whereas the original IR2301 is RoHS non-compliant. This distinction is significant for applications subject to environmental regulations. The substitute part carries a Moisture Sensitivity Level (MSL) of 2 (1 Year), compared to MSL 1 (Unlimited) for the original, requiring appropriate handling and storage protocols during the one-year window.

Product Status Impact: Both parts carry restricted product status designations. The original IR2301 is classified as Obsolete, while the IR2301SPBF is designated Not For New Designs. For ongoing maintenance and repair of existing systems using the IR2301, the IR2301SPBF is the appropriate substitute. For new design initiatives, alternative gate driver architectures should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the IR2301SPBF directly replace the IR2301 in existing half-bridge applications?

A: Yes. The IR2301SPBF provides identical electrical performance across all critical parameters: dual-channel independent drivers, 5V to 20V supply operation, 200mA/350mA peak output current, 600V bootstrap voltage rating, and 8-SOIC package form factor. Functional substitution is direct.

Q: What is the difference between the driven configurations listed for these parts?

A: The original IR2301 is specified as Half-Bridge configuration. The IR2301SPBF is specified as High-Side or Low-Side configuration. Despite this specification difference, both parts contain identical dual-channel driver architecture and can operate in half-bridge topologies. The specification difference reflects marketing categorization rather than fundamental hardware differences.

Q: Are there packaging differences between IR2301 and IR2301SPBF?

A: Both parts use the 8-SOIC package with identical dimensions (0.154" width, 3.90mm). The IR2301SPBF is supplied in Tube packaging, while the original IR2301 packaging specification is not detailed. PCB footprint and land pattern requirements are identical.

Q: What compliance changes should be considered when substituting?

A: The IR2301SPBF is ROHS3 compliant, whereas the IR2301 is RoHS non-compliant. If your application or market requires RoHS compliance, the IR2301SPBF satisfies this requirement. Additionally, the IR2301SPBF has a Moisture Sensitivity Level (MSL) of 2 (1 Year), requiring proper handling within a one-year window from manufacturing. The original IR2301 has MSL 1 (Unlimited), allowing indefinite storage without moisture sensitivity concerns.

Q: Are the logic input voltage thresholds identical?

A: Yes. Both parts specify identical logic voltage thresholds: VIL = 0.8V and VIH = 2.9V. Input signal conditioning and interface requirements are unchanged.

Q: What is the significance of the "Not For New Designs" status on the IR2301SPBF?

A: This designation indicates the part is available for existing system support and maintenance but should not be selected for new product development. For new designs, evaluate current-generation gate driver alternatives from Infineon or other manufacturers.
