IR2011 Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The IR2011 is a high-side or low-side gate driver IC designed for N-channel MOSFET applications in power management circuits. This component operates as an inverting driver with independent dual-channel configuration, supporting supply voltages between 10V and 20V. The IR2011 is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the IR2011 is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish valid substitute relationships:

• Driven configuration must remain high-side or low-side capable
• Channel type must be independent dual-channel
• Number of drivers must equal 2
• Gate type must support N-channel MOSFET switching
• Supply voltage range must encompass 10V ~ 20V
• Logic voltage thresholds (VIL, VIH) must match 0.7V and 2.2V
• Peak output current (source and sink) must maintain 1A specification
• Input type must remain inverting
• Bootstrap voltage rating must meet or exceed 200V
• Rise and fall time characteristics must align with 35ns and 20ns
• Operating temperature range must cover -40°C ~ 150°C
• Package must be 8-DIP through-hole configuration

The IR2011PBF meets all specified parameters and qualifies as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can IR2011PBF replace IR2011 in existing designs? A: Yes. The IR2011PBF provides complete electrical and mechanical equivalence. All functional parameters, pin configurations, and performance characteristics are identical. Direct substitution is supported without circuit modification.

Q: What is the primary reason for substitution? A: The IR2011 is classified as obsolete. The IR2011PBF maintains active product status, ensuring long-term supply chain availability and manufacturing continuity.

Q: Are there packaging differences between these parts? A: No. Both components use 8-DIP through-hole packaging with identical 0.300" (7.62mm) body dimensions. PCB layouts and mounting procedures remain unchanged.

Q: Do compliance certifications differ? A: Both parts share identical ECCN and HTSUS classifications. RoHS and REACH status should be verified against current component documentation for specific procurement requirements.

Q: What is the bootstrap voltage specification used for? A: The 200V bootstrap voltage rating defines the maximum voltage that can be applied to the high-side driver output. This specification is critical for high-voltage switching applications and must be respected in circuit design.
