IR2114SS Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IR2114SS is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for driving IGBT gates in power management applications. This device features independent dual-channel configuration with non-inverting input logic and operates across a 11.5V to 20V supply voltage range.

The IR2114SS carries an Obsolete product status, making it necessary to identify functionally equivalent alternatives for new designs and ongoing production requirements. The substitute part IR2114SSPBF provides direct functional compatibility while offering improved compliance status for modern applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IR2114SS is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-Bridge topology
• Number of Drivers: Dual independent channels
• Gate Type: IGBT compatibility
• Supply Voltage Range: 11.5V ~ 20V
• Output Current Specifications: 2A source, 3A sink
• Bootstrap Voltage Rating: 600V maximum
• Package Type: 24-SSOP form factor
• Thermal Operating Range: -40°C ~ 150°C

The IR2114SSPBF meets all electrical and mechanical parameters required for direct substitution. Both parts share identical base product number (IR2114) and maintain functional equivalence across all specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

The IR2114SSPBF is the direct functional equivalent for IR2114SS applications. Selection between these parts is determined by compliance and product lifecycle requirements:

IR2114SS is designated Obsolete with RoHS non-compliant status. This part remains suitable only for legacy system maintenance where existing inventory is available and regulatory compliance is not a constraint.

IR2114SSPBF carries Not For New Designs status but provides ROHS3 compliance, making it the appropriate choice for applications requiring modern regulatory adherence. The improved RoHS compliance and specified packaging (Tube) support production workflows for systems with environmental and compliance requirements.

Both parts maintain identical electrical performance and 24-SSOP package compatibility, enabling direct PCB-level substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can IR2114SSPBF replace IR2114SS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. The 24-SSOP package footprint is identical, and all electrical characteristics including supply voltage, output current, and timing specifications match exactly. Direct substitution is possible without circuit modification.

Q: What is the difference between IR2114SS and IR2114SSPBF?

A: The primary differences are product status and compliance certification. IR2114SS is Obsolete and RoHS non-compliant. IR2114SSPBF is Not For New Designs but ROHS3 compliant. Electrically and functionally, both parts are identical. The packaging format differs (unspecified vs. Tube), which may affect procurement and handling procedures.

Q: Are there any thermal or operating condition differences?

A: No. Both parts operate across the identical temperature range of -40°C to 150°C (junction temperature) and maintain the same electrical performance across all specified supply voltage and load conditions.

Q: What does the Moisture Sensitivity Level (MSL) difference mean?

A: IR2114SS has MSL 1 (Unlimited shelf life without moisture control). IR2114SSPBF has MSL 3 (168-hour maximum exposure to 85% relative humidity at 85°C before reflow). This affects storage and handling procedures but does not impact electrical performance or functionality.

Q: Is the 24-SSOP package footprint identical between both parts?

A: Yes. Both parts use the 24-SSOP package with 0.209" width and 5.30mm dimensions. PCB layouts and footprints are directly compatible without modification.
