IRS21867SPBF Equivalent & Substitute Parts

Part Overview

The IRS21867SPBF is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for driving IGBT and N-Channel MOSFET configurations in power management applications. This device operates with a supply voltage range of 10V to 20V and delivers peak output currents of 4A for both source and sink operations. The IRS21867SPBF is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRS21867SPBF is determined by strict equivalence across the following critical parameters:

• Driven configuration (half-bridge topology)
• Number of independent driver channels (2)
• Compatible gate types (IGBT and N-Channel MOSFET)
• Supply voltage range (10V ~ 20V)
• Peak output current capability (4A source and sink)
• Bootstrap voltage rating (600V maximum)
• Switching characteristics (rise and fall times)
• Package form factor (8-SOIC)
• Input logic levels (CMOS, TTL compatible)

The IRS21867STRPBF meets all these criteria and represents the active production equivalent of the obsolete IRS21867SPBF, differing only in packaging format (Cut Tape & Digi-Reel versus Tube).

Parameter Comparison

Engineering Selection Recommendations

The IRS21867STRPBF is the direct functional equivalent for the obsolete IRS21867SPBF. Both devices share identical electrical specifications, thermal ratings, and package geometry. The IRS21867STRPBF maintains active production status with Infineon Technologies and carries equivalent compliance certifications (ROHS3, REACH Unaffected). The only distinction is packaging format: the IRS21867SPBF is supplied in Tube packaging, while the IRS21867STRPBF is available in Cut Tape and Digi-Reel formats. For new designs and legacy system support, the IRS21867STRPBF provides full electrical and mechanical compatibility with superior supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the IRS21867STRPBF directly replace the IRS21867SPBF in existing designs?

A: Yes. The IRS21867STRPBF is electrically and mechanically identical to the IRS21867SPBF. Both devices feature the same 8-SOIC package geometry, pin configuration, and electrical characteristics. No circuit modifications are required.

Q: What is the difference between Tube and Cut Tape packaging?

A: Tube packaging supplies components in plastic tubes for manual handling and small-quantity applications. Cut Tape and Digi-Reel packaging provides components on continuous tape for automated pick-and-place assembly. The electrical and functional performance is identical; packaging format affects only handling and assembly methodology.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the IRS21867SPBF and IRS21867STRPBF carry identical RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 2 ratings. Thermal and electrical specifications are fully equivalent.

Q: Why is the IRS21867SPBF classified as obsolete?

A: Obsolete status indicates that Infineon Technologies has discontinued production of this specific part number. The IRS21867STRPBF represents the active production equivalent and is recommended for all new procurement and design activities.

Q: What supply voltage range does this gate driver support?

A: The IRS21867STRPBF operates with a supply voltage range of 10V to 20V, making it suitable for a wide range of power management applications including industrial motor drives and power conversion systems.

Q: What is the maximum bootstrap voltage rating?

A: The maximum high-side bootstrap voltage is 600V, which defines the maximum voltage differential that can be applied across the high-side gate driver circuit in half-bridge configurations.
