IR2131S Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IR2131S is a half-bridge gate driver IC 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 provides independent channel control with peak output currents of 250mA (source) and 500mA (sink). The IR2131S is classified as obsolete, making identification of suitable substitute parts essential for ongoing system design and component procurement.

Substitute Part Grouping Explanation

Substitution of the IR2131S is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-Bridge topology
• Number of Drivers: 6 independent channels
• Gate Type: IGBT and N-Channel MOSFET compatibility
• Voltage - Supply: 10V ~ 20V operating range
• Logic Voltage Levels: VIL 0.8V, VIH 2.2V
• Current - Peak Output: 250mA source, 500mA sink
• Input Type: Inverting logic
• High Side Voltage - Max (Bootstrap): 600V
• Package / Case: 28-SOIC form factor
• Operating Temperature Range: -40°C ~ 150°C (TJ)

The IR2131SPBF maintains full electrical and mechanical compatibility with the IR2131S across all specified parameters, enabling direct substitution in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The IR2131SPBF is the direct substitute for the IR2131S. Both devices share identical electrical specifications and mechanical packaging, ensuring pin-for-pin compatibility and functional equivalence in half-bridge gate driver applications.

The primary distinction between these parts is product status: the IR2131S is classified as obsolete, while the IR2131SPBF maintains active status. This difference is significant for long-term component availability and supply chain planning. The IR2131SPBF is manufactured by International Rectifier and is available in bulk packaging with current inventory levels supporting production requirements.

Both parts comply with EAR99 export classification and are subject to HTSUS code 8542.39.0001. Neither part is RoHS compliant, and both are unaffected by REACH regulations. The IR2131S carries Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

For new designs or component replenishment, the IR2131SPBF is the appropriate selection due to its active product status and assured long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the IR2131SPBF be used as a direct replacement for the IR2131S?

A: Yes. The IR2131SPBF is electrically and mechanically equivalent to the IR2131S. All electrical parameters, including supply voltage, output current, logic levels, timing characteristics, and operating temperature range are identical. The 28-SOIC package dimensions are the same, enabling direct PCB substitution without design modification.

Q: What is the significance of the product status difference between IR2131S and IR2131SPBF?

A: The IR2131S is classified as obsolete, indicating that Infineon Technologies has discontinued production and support for this part number. The IR2131SPBF maintains active status, meaning International Rectifier continues to manufacture and support this device. For ongoing production and future designs, the active part number ensures component availability and manufacturer support.

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

A: Both parts share identical export classification (EAR99) and HTSUS coding (8542.39.0001). Neither part is RoHS compliant, and both are unaffected by REACH regulations. The IR2131S specifies Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints. Compliance profiles are equivalent for both devices.

Q: What are the critical parameters that define substitution eligibility for half-bridge gate drivers?

A: Substitution eligibility is determined by equivalence across driven configuration (half-bridge topology), number of drivers (6 channels), gate type compatibility (IGBT and N-Channel MOSFET), supply voltage range (10V ~ 20V), logic voltage levels (VIL 0.8V, VIH 2.2V), peak output current specifications (250mA source, 500mA sink), input type (inverting), bootstrap voltage rating (600V maximum), timing characteristics (80ns rise, 40ns fall), operating temperature range (-40°C ~ 150°C), and package form factor (28-SOIC). All parameters must match for direct substitution.

Q: Is the 28-SOIC package suitable for surface mount assembly?

A: Yes. Both the IR2131S and IR2131SPBF are specified for surface mount assembly in 28-SOIC packaging with 0.295" (7.50mm) width. This package is compatible with standard surface mount technology (SMT) assembly processes and equipment.
