IR2302S Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IR2302S is a half-bridge gate driver IC manufactured by Infineon Technologies, designed to drive IGBT and N-Channel MOSFET configurations in power management applications. The device operates with a supply voltage range of 5V to 20V and supports a maximum bootstrap voltage of 600V, making it suitable for industrial power conversion circuits.

The IR2302S is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement. Substitute parts must maintain electrical compatibility across critical parameters including supply voltage, logic thresholds, output current capabilities, and thermal operating range to ensure functional equivalence in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IR2302S is determined by strict adherence to the following critical parameters:

Electrical Compatibility Requirements:

• Driven configuration must be half-bridge with 2 drivers
• Gate type must support IGBT and N-Channel MOSFET
• Supply voltage range must encompass or exceed 5V ~ 20V
• Logic voltage thresholds (VIL, VIH) must be compatible with 0.8V, 2.9V
• Peak output current (source and sink) must meet or exceed 200mA and 350mA respectively
• Input type must be non-inverting
• Bootstrap voltage rating must be minimum 600V
• Operating temperature range must cover -40°C ~ 150°C

Mechanical Compatibility Requirements:

• Package must be 8-SOIC form factor
• Mounting type must be surface mount

Identified Substitute Parts:

1. IR2302SPBF (Infineon Technologies) - Direct manufacturer equivalent with identical electrical specifications and 8-SOIC packaging. Product status is "Not For New Designs" with RoHS3 compliance.

2. FAN7080MX-GF085 (onsemi) - Manufacturer-recommended substitute with enhanced electrical performance characteristics, active product status, and automotive-grade qualification (AEC-Q100). Exceeds minimum requirements for peak output current and provides faster switching times.

Parameter Comparison

Engineering Selection Recommendations

IR2302SPBF Selection Criteria: IR2302SPBF is the direct manufacturer equivalent from Infineon Technologies with identical electrical and mechanical specifications to the IR2302S. This part is suitable for applications requiring exact functional replacement where RoHS3 compliance is required. The product status "Not For New Designs" indicates limited long-term availability; however, current inventory levels support near-term procurement needs.

FAN7080MX-GF085 Selection Criteria: FAN7080MX-GF085 is classified as active product status with manufacturer-recommended substitution status. This part exceeds the minimum electrical requirements of the IR2302S across multiple parameters: peak output current (300mA source, 600mA sink versus 200mA, 350mA), and switching speed (40ns rise, 25ns fall versus 130ns, 50ns). The device carries AEC-Q100 automotive qualification and RoHS3 compliance. FAN7080MX-GF085 is appropriate for new designs and applications requiring long-term component availability and enhanced performance margins.

Compliance Considerations: Both substitute parts maintain RoHS3 compliance and REACH unaffected status. The IR2302S is RoHS non-compliant; therefore, designs requiring regulatory compliance must transition to either IR2302SPBF or FAN7080MX-GF085.

Frequently Asked Questions (FAQ)

Q: Can IR2302SPBF be used as a direct replacement for IR2302S? A: Yes. IR2302SPBF is electrically and mechanically identical to IR2302S, with the same supply voltage range (5V ~ 20V), output current ratings (200mA source, 350mA sink), and 8-SOIC packaging. The primary differences are product status and RoHS compliance level.

Q: What are the key differences between IR2302SPBF and FAN7080MX-GF085? A: Both parts are half-bridge gate drivers in 8-SOIC packages with compatible logic thresholds and 600V bootstrap ratings. FAN7080MX-GF085 provides higher peak output current (300mA source, 600mA sink), faster switching times (40ns/25ns versus 130ns/50ns), and carries active product status with AEC-Q100 automotive qualification. IR2302SPBF maintains exact electrical specifications of the original IR2302S.

Q: Is FAN7080MX-GF085 compatible with existing IR2302S circuit designs? A: FAN7080MX-GF085 is electrically compatible with IR2302S designs. The device operates within the same supply voltage range (5.5V ~ 20V encompasses 5V ~ 20V), maintains non-inverting input configuration, and supports identical gate types (IGBT, N-Channel MOSFET). The enhanced output current and faster switching characteristics provide improved performance margins without requiring circuit modifications.

Q: What is the significance of product status classifications? A: Product status indicates manufacturer support and availability outlook. "Obsolete" (IR2302S) indicates end-of-life with no further support. "Not For New Designs" (IR2302SPBF) indicates limited availability and no new design recommendations. "Active" (FAN7080MX-GF085) indicates full manufacturer support and long-term availability for new and existing designs.

Q: Are there packaging differences between these parts? A: All three parts use 8-SOIC surface mount packaging (0.154" width, 3.90mm). IR2302SPBF is supplied in tube packaging, while FAN7080MX-GF085 is supplied in tape and reel format. Both packaging formats are compatible with standard surface mount assembly processes.

Q: Does FAN7080MX-GF085 require circuit design changes? A: No circuit design changes are required. FAN7080MX-GF085 maintains pin-compatible 8-SOIC packaging and non-inverting input logic. The enhanced electrical characteristics (higher output current, faster switching) are backward compatible with designs specified for IR2302S minimum requirements.
