IRS2005SPBF Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IRS2005SPBF 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 features non-inverting logic inputs, independent channel control, and operates across a 10V to 20V supply voltage range with a maximum bootstrap voltage of 200V.

The IRS2005SPBF is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications utilizing this gate driver topology.

Substitute Part Grouping Explanation

Substitution of the IRS2005SPBF is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-Bridge topology
• Channel Type: Independent channels
• Number of Drivers: 2 drivers
• Gate Type: IGBT and N-Channel MOSFET compatibility
• Voltage - Supply: 10V ~ 20V operating range
• Logic Voltage Thresholds: VIL 0.8V, VIH 2.5V
• Current - Peak Output: Source 290mA, Sink 600mA
• Input Type: Non-Inverting logic
• High Side Voltage - Max (Bootstrap): 200V
• Rise / Fall Time (Typ): 70ns rise, 30ns fall
• Operating Temperature: -40°C ~ 150°C (TJ)
• Package / Case: 8-SOIC form factor
• Mounting Type: Surface Mount

The IRS2005STRPBF meets all these criteria and is classified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The IRS2005STRPBF is the direct substitute for the obsolete IRS2005SPBF. Both parts are manufactured by Infineon Technologies and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: the IRS2005SPBF is obsolete, while the IRS2005STRPBF is active and maintains current manufacturing support. Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production continuity.

The IRS2005STRPBF is available in Cut Tape (CT) and Digi-Reel packaging options with significantly higher inventory availability (37,900 pieces in stock versus 960 pieces for the obsolete variant), supporting both prototype and volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can the IRS2005STRPBF directly replace the IRS2005SPBF in existing designs?

A: Yes. The IRS2005STRPBF is electrically and mechanically identical to the IRS2005SPBF across all specified parameters. No circuit modifications or PCB layout changes are required for direct substitution.

Q: Are there differences in packaging between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. The IRS2005STRPBF offers additional packaging options including Cut Tape (CT) and Digi-Reel formats, while the IRS2005SPBF packaging format is not specified in the available data.

Q: What is the significance of the product status difference?

A: The IRS2005SPBF is classified as obsolete, indicating discontinued manufacturing and limited availability. The IRS2005STRPBF is active, ensuring ongoing manufacturing support, technical documentation updates, and reliable supply chain access for current and future production.

Q: Are compliance certifications identical between these parts?

A: Yes. Both the IRS2005SPBF and IRS2005STRPBF maintain ROHS3 compliance, REACH unaffected status, and identical Moisture Sensitivity Level (MSL) ratings of 2 (1 Year).

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching driven configuration (half-bridge), channel type (independent), number of drivers (2), gate type (IGBT and N-Channel MOSFET), supply voltage range (10V ~ 20V), logic voltage thresholds (VIL 0.8V, VIH 2.5V), peak output current (290mA source, 600mA sink), input type (non-inverting), bootstrap voltage (200V maximum), and timing characteristics (70ns rise, 30ns fall).
