IR2108SPBF Equivalent & Substitute Parts

Part Overview

The IR2108SPBF is a half-bridge gate driver IC manufactured by Infineon Technologies, designed to drive IGBT and N-channel MOSFET devices in power management applications. This device operates with a supply voltage range of 10V to 20V and provides independent dual-channel gate driving with peak output currents of 200mA (source) and 350mA (sink).

The IR2108SPBF is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure continued availability for new designs, production continuity, and system reliability when original inventory becomes depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2108SPBF is determined by strict equivalence across the following critical parameters:

• Driven configuration (half-bridge topology)
• Number of independent driver channels (2)
• Gate type compatibility (IGBT and N-channel MOSFET)
• Supply voltage range (10V ~ 20V)
• Logic input voltage thresholds (VIL 0.8V, VIH 2.9V)
• Peak output current specifications (200mA source, 350mA sink)
• Input signal polarity (non-inverting)
• Bootstrap voltage rating (600V maximum)
• Timing characteristics (150ns rise, 50ns fall)
• Operating temperature range (-40°C ~ 150°C)
• Physical package form factor (8-SOIC)
• Surface mount compatibility
• Regulatory compliance (ROHS3, REACH Unaffected)

The IR2108STRPBF qualifies as a direct substitute based on identical electrical specifications and functional characteristics. The primary distinction is packaging format: the substitute is supplied in tape and reel (TR) configuration rather than tube packaging, and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The IR2108STRPBF is the direct equivalent substitute for the IR2108SPBF. Both parts share identical electrical specifications, functional characteristics, and regulatory compliance certifications. The IR2108STRPBF maintains active product status with Infineon Technologies, ensuring long-term availability and supply chain stability.

Selection of the IR2108STRPBF is appropriate for applications requiring the IR2108SPBF functionality. The packaging format difference (tape and reel versus tube) does not affect electrical performance or circuit compatibility. Both parts comply with ROHS3 and REACH requirements, maintaining equivalent environmental and regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the IR2108STRPBF directly replace the IR2108SPBF in existing designs?

A: Yes. The IR2108STRPBF is electrically and functionally identical to the IR2108SPBF. All electrical parameters, timing characteristics, and gate drive capabilities are equivalent. No circuit modifications are required.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging supplies individual components in a plastic tube, typically for lower-volume orders. Tape and reel packaging supplies components on continuous carrier tape wound on a reel, optimized for automated assembly processes. Both formats contain identical components with no electrical differences.

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

A: No. Both the IR2108SPBF and IR2108STRPBF carry identical ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 2, 1 Year) is equivalent for both parts.

Q: Why is the IR2108SPBF classified as obsolete?

A: The IR2108SPBF has been superseded by the IR2108STRPBF in Infineon's product portfolio. The IR2108STRPBF maintains active status and is the recommended part for new designs and production continuity.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the same temperature range of -40°C to 150°C (junction temperature), ensuring equivalent thermal performance in all operating conditions.

Q: Can these parts be used interchangeably in high-volume manufacturing?

A: Yes. The IR2108STRPBF tape and reel format is specifically designed for high-volume automated assembly, making it the preferred choice for production environments. The electrical equivalence ensures seamless integration into existing manufacturing processes.
