IR2111 Half-Bridge Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The IR2111 is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for driving IGBT and N-Channel MOSFET configurations in power management applications. The device operates with a supply voltage range of 10V to 20V and provides synchronized dual-channel gate driving with peak output currents of 250mA (source) and 500mA (sink).

The IR2111 is classified as obsolete, which necessitates identification of equivalent substitute components for new designs and ongoing system support. The IR2111PBF represents the direct functional equivalent with updated compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2111 is determined by strict equivalence across the following critical parameters:

• Driven configuration (Half-Bridge)
• Number of drivers (2 channels)
• Gate type compatibility (IGBT, N-Channel MOSFET)
• Supply voltage range (10V ~ 20V)
• Logic voltage thresholds (VIL 8.3V, VIH 12.6V)
• Peak output current specifications (250mA source, 500mA sink)
• Input signal type (Non-Inverting)
• Bootstrap voltage rating (600V maximum)
• Timing characteristics (80ns rise, 40ns fall)
• Operating temperature range (-40°C ~ 150°C)
• Physical package format (8-DIP through-hole)

The IR2111PBF meets all these criteria and is identified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The IR2111PBF is the direct functional equivalent of the IR2111. Both devices are manufactured by Infineon Technologies and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is compliance status. The IR2111 is classified as obsolete and RoHS non-compliant, while the IR2111PBF is designated as "Not For New Designs" and achieves ROHS3 compliance. For applications requiring RoHS compliance or long-term component availability, the IR2111PBF is the appropriate selection.

Both devices carry identical REACH and ECCN classifications, indicating equivalent regulatory treatment for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can IR2111PBF be used as a direct replacement for IR2111 in existing designs?
