IX2120B Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The IX2120B is a half-bridge gate driver IC manufactured by IXYS Integrated Circuits Division, designed for driving IGBT and N-Channel MOSFET configurations in power management applications. This device operates with a supply voltage range of 15V to 20V and delivers peak output currents of 2A for both source and sink operations. The IX2120B is classified as obsolete, making identification of functionally equivalent substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IX2120B is determined by strict alignment of the following electrical and mechanical parameters:

• Driven Configuration: Half-bridge topology with independent dual-channel drivers
• Gate Type Compatibility: Support for IGBT and N-Channel MOSFET gate driving
• Supply Voltage Range: 15V to 20V operation
• Logic Voltage Thresholds: VIL and VIH specifications matching 6V and 9.5V
• Peak Output Current: Minimum 2A source and sink capability
• Input Signal Type: Non-inverting logic configuration
• Bootstrap Voltage Rating: Minimum 1200V high-side voltage capability
• Package Form Factor: 28-SOIC surface mount package
• Operating Temperature Range: -40°C to 150°C junction temperature

The IR2113SPBF qualifies as a substitute based on functional equivalence within these defined parameters.

Engineering Selection Recommendations

The IR2113SPBF is the manufacturer-recommended substitute for the obsolete IX2120B. Selection of this substitute is justified on the following basis:

• Product Status Alignment: The IR2113SPBF maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete IX2120B.
• Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, confirming equivalent export control and tariff treatment.
• Functional Equivalence: The IR2113SPBF maintains the same half-bridge gate driver topology, dual-channel independent configuration, and support for IGBT and N-Channel MOSFET gate driving as the IX2120B.
• Electrical Parameter Compatibility: The substitute meets or exceeds the supply voltage, logic voltage thresholds, peak output current, bootstrap voltage rating, and operating temperature specifications of the original component.

Frequently Asked Questions (FAQ)

Q: Can the IR2113SPBF directly replace the IX2120B in existing designs?

A: The IR2113SPBF is functionally equivalent to the IX2120B across all specified electrical parameters and driven configuration requirements. Direct substitution is supported for applications requiring half-bridge gate driving of IGBT and N-Channel MOSFET devices within the specified voltage and current ranges.

Q: Are there package compatibility considerations between these components?

A: Both the IX2120B and IR2113SPBF utilize the 28-SOIC surface mount package form factor. PCB layout and footprint compatibility is maintained between these components.

Q: What is the significance of the IX2120B being classified as obsolete?

A: Obsolete status indicates that the IX2120B is no longer in active production. The IR2113SPBF, maintained in active production status, provides a path for continued system support and new design implementations without supply chain interruption.

Q: Are regulatory certifications equivalent between these parts?

A: Both components share identical ECCN and HTSUS classifications, confirming equivalent regulatory treatment for export control and tariff purposes. RoHS3 compliance is confirmed for the IX2120B; compliance status for the IR2113SPBF is not specified in the provided technical data.
