IR2133S Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IR2133S is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for driving IGBT and N-Channel MOSFET configurations in 3-phase applications. The device operates with a supply voltage range of 10V to 20V and provides peak output currents of 250mA (source) and 500mA (sink). The IR2133S is classified as obsolete, making identification of suitable substitute components necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2133S is determined by strict equivalence across the following critical parameters:

• Driven configuration (Half-Bridge)
• Channel type (3-Phase)
• Number of drivers (6)
• Gate type compatibility (IGBT, N-Channel MOSFET)
• Supply voltage range (10V ~ 20V)
• Logic voltage thresholds (VIL 0.8V, VIH 2.2V)
• Peak output current specifications (250mA source, 500mA sink)
• Input type (Inverting)
• Bootstrap voltage rating (600V maximum)
• Package form factor (28-SOIC)

The IR2133SPBF meets all these criteria and is identified as a direct substitute for the obsolete IR2133S.

Parameter Comparison

Engineering Selection Recommendations

The IR2133SPBF is the direct functional equivalent of the IR2133S, with identical electrical and mechanical specifications across all critical parameters. The primary distinction lies in compliance status: the IR2133SPBF achieves ROHS3 compliance, whereas the IR2133S is RoHS non-compliant. The IR2133SPBF carries a product status designation of "Not For New Designs," indicating it is suitable for replacement and maintenance applications but not recommended for new product development initiatives.

For applications requiring RoHS compliance or modern manufacturing standards, the IR2133SPBF is the appropriate selection. The difference in Moisture Sensitivity Level (MSL 1 versus MSL 3) reflects updated handling and storage requirements for the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the IR2133SPBF directly replace the IR2133S in existing designs?

A: Yes. The IR2133SPBF is electrically and mechanically identical to the IR2133S across all functional parameters, including supply voltage, output current, timing characteristics, and package form factor. Direct substitution is supported without circuit modification.

Q: What is the significance of the RoHS compliance difference?

A: The IR2133S is RoHS non-compliant, while the IR2133SPBF is ROHS3 compliant. This distinction affects manufacturing processes, supply chain requirements, and regulatory compliance for end products. Applications subject to RoHS regulations must use the IR2133SPBF.

Q: Does the Moisture Sensitivity Level (MSL) difference affect functionality?

A: No. MSL differences reflect storage and handling requirements only. MSL 3 (168 Hours) for the IR2133SPBF requires more controlled humidity conditions during storage compared to MSL 1 (Unlimited) for the IR2133S. Both devices function identically once installed on a circuit board.

Q: Are there any pin-to-pin or footprint differences between these parts?

A: No. Both devices use the 28-SOIC package with identical pin assignments and footprint dimensions (0.295", 7.50mm Width). PCB layouts require no modification.

Q: Why is the IR2133S classified as obsolete?

A: The IR2133S has reached end-of-life status. The IR2133SPBF represents the current equivalent offering from Infineon Technologies for this gate driver topology.
