IRS2008SPBF Equivalent & Substitute Parts

Part Overview

The IRS2008SPBF is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for driving N-channel MOSFETs in synchronous half-bridge configurations. This device operates with a supply voltage range of 10V to 20V and delivers peak output currents of 290mA (source) and 600mA (sink), making it suitable for power management applications requiring precise gate control.

The IRS2008SPBF is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance of systems utilizing this gate driver architecture.

Substitute Part Grouping Explanation

Substitution of the IRS2008SPBF is determined by strict equivalence across the following critical parameters:

• Driven Configuration & Channel Type: Half-bridge, synchronous topology with 2 drivers
• Gate Control: N-channel MOSFET non-inverting input
• Electrical Performance: Supply voltage 10V–20V, logic thresholds 0.8V/2.5V, output currents 290mA/600mA, bootstrap voltage 200V maximum
• Timing Characteristics: Rise/fall times of 70ns and 30ns respectively
• Thermal Range: Operating temperature -40°C to 150°C
• Physical Form Factor: 8-SOIC package with 0.154" width (3.90mm)
• Regulatory Compliance: ROHS3 compliance and MSL 2 rating

The IRS2008STRPBF meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete IRS2008SPBF.

Parameter Comparison

Engineering Selection Recommendations

The IRS2008STRPBF is the direct substitute for the obsolete IRS2008SPBF. Both parts are manufactured by Infineon Technologies and share identical electrical, thermal, and mechanical specifications. The IRS2008STRPBF maintains active product status, ensuring ongoing availability and supply chain support.

Both parts comply with ROHS3 regulations and carry identical REACH status classification. The MSL 2 rating applies to both devices, requiring storage conditions of 30°C/60% RH or lower for one year.

Selection of the IRS2008STRPBF eliminates obsolescence risk while preserving full functional compatibility with existing circuit designs and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the IRS2008STRPBF be used as a direct replacement for the IRS2008SPBF?

A: Yes. The IRS2008STRPBF is electrically and mechanically identical to the IRS2008SPBF. All electrical parameters, timing characteristics, package dimensions, and regulatory certifications are equivalent. Pin-for-pin compatibility is maintained.

Q: What is the primary reason to substitute the IRS2008SPBF?

A: The IRS2008SPBF is classified as obsolete. The IRS2008STRPBF is an active product offering equivalent performance with assured long-term availability.

Q: Are there any differences in packaging between these parts?

A: Both parts use the 8-SOIC package with identical dimensions (0.154" width, 3.90mm). The IRS2008STRPBF is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, while the IRS2008SPBF packaging format is not specified in the available data.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the IRS2008SPBF and IRS2008STRPBF are ROHS3 compliant, REACH unaffected, and carry MSL 2 moisture sensitivity ratings with a one-year storage window.

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

A: Substitution is determined by matching the half-bridge synchronous topology, 2-driver configuration, N-channel MOSFET gate control, 10V–20V supply range, 290mA/600mA output currents, 200V bootstrap voltage, and -40°C to 150°C operating temperature range.
