IR2302SPBF Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IR2302SPBF 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 operates with a supply voltage range of 5V to 20V and features non-inverting input logic with a maximum bootstrap voltage of 600V.

The IR2302SPBF carries a "Not For New Designs" product status, indicating that Infineon has discontinued active development and support for this component. This status necessitates identifying functionally equivalent substitute parts that maintain compatibility with existing circuit designs while offering improved availability, performance characteristics, or compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IR2302SPBF is determined by strict alignment with the following critical parameters:

Mandatory Matching Criteria:

• Driven Configuration: Half-Bridge
• Channel Type: Synchronous
• Number of Drivers: 2
• Gate Type: IGBT, N-Channel MOSFET
• Input Type: Non-Inverting
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• High Side Voltage - Max (Bootstrap): 600V minimum

Allowable Parameter Ranges for Substitution:

• Voltage - Supply: Must encompass or exceed the 5V ~ 20V range
• Logic Voltage - VIL, VIH: Must be compatible with 0.8V, 2.9V thresholds
• Current - Peak Output (Source, Sink): Must meet or exceed 200mA source and 350mA sink requirements
• Rise / Fall Time: May be equal to or faster than 130ns rise and 50ns fall
• Operating Temperature: Must support -40°C ~ 150°C range
• RoHS Status: ROHS3 Compliant required

The FAN7080MX-GF085 from onsemi qualifies as a direct substitute based on these criteria, offering enhanced performance characteristics and active product status with automotive-grade qualification.

Engineering Selection Recommendations

The FAN7080MX-GF085 is a qualified substitute for the IR2302SPBF based on the following engineering factors:

Functional Equivalence: All mandatory parameters align precisely. The FAN7080MX-GF085 maintains identical half-bridge synchronous driver configuration, gate type compatibility, input logic type, bootstrap voltage rating, and package form factor.

Performance Enhancement: The substitute part delivers superior electrical performance with peak output currents of 300mA source and 600mA sink (versus 200mA and 350mA), and significantly faster switching characteristics with 40ns rise time and 25ns fall time (versus 130ns and 50ns). These improvements provide design margin and reduced switching losses in power conversion applications.

Product Status and Compliance: The FAN7080MX-GF085 carries Active product status with AEC-Q100 automotive qualification, ensuring long-term availability and reliability certification. The IR2302SPBF's "Not For New Designs" status indicates end-of-life trajectory, making the onsemi alternative the appropriate selection for sustained supply chain continuity.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status. The substitute part's automotive-grade qualification provides additional assurance for mission-critical applications.

Packaging and Logistics: The FAN7080MX-GF085 is supplied in Tape & Reel format with MSL 3 (168 Hours) rating, compared to the IR2302SPBF's Tube packaging with MSL 2 (1 Year). Standard moisture control procedures apply for both formats.

Frequently Asked Questions (FAQ)

Q: Can the FAN7080MX-GF085 directly replace the IR2302SPBF in existing circuit designs?

A: Yes. The FAN7080MX-GF085 is a direct functional equivalent with identical package, pin configuration, and electrical interface. No circuit modifications are required. The substitute part's enhanced performance characteristics (higher output current and faster switching) are backward-compatible with designs specified for the IR2302SPBF.

Q: What are the key differences between these two gate driver ICs?

A: The primary differences are product status, performance specifications, and qualification level. The FAN7080MX-GF085 offers higher peak output currents (300mA/600mA versus 200mA/350mA), faster switching times (40ns/25ns versus 130ns/50ns), and carries AEC-Q100 automotive qualification. The IR2302SPBF is discontinued (Not For New Designs status), while the FAN7080MX-GF085 is in active production.

Q: Are there any supply voltage compatibility concerns?

A: The FAN7080MX-GF085 specifies a minimum supply voltage of 5.5V, compared to the IR2302SPBF's 5V minimum. For applications operating at exactly 5V, verification of the substitute part's performance at this boundary condition is necessary. Both parts support the full 20V maximum supply voltage.

Q: How do the logic input thresholds compare?

A: Both parts share identical VIL (0.8V) thresholds. The VIH threshold differs slightly: IR2302SPBF at 2.9V versus FAN7080MX-GF085 at 2.7V. This minor difference is within standard logic interface tolerances and does not affect compatibility with typical digital control circuits.

Q: What is the significance of the AEC-Q100 qualification on the FAN7080MX-GF085?

A: AEC-Q100 is an automotive industry qualification standard that certifies component reliability under stringent environmental and operational stress conditions. This certification is not applicable to the IR2302SPBF. For applications requiring automotive-grade reliability assurance, the FAN7080MX-GF085 provides documented qualification.

Q: Are there packaging format differences that affect procurement or assembly?

A: Yes. The IR2302SPBF is supplied in Tube packaging, while the FAN7080MX-GF085 is supplied in Tape & Reel format. Tape & Reel is standard for high-volume automated assembly. Moisture sensitivity levels also differ: MSL 2 (1 Year) for IR2302SPBF versus MSL 3 (168 Hours) for FAN7080MX-GF085. Both require standard moisture control during storage and handling.

Q: Can the faster switching times of the FAN7080MX-GF085 cause any circuit compatibility issues?

A: The faster switching characteristics of the FAN7080MX-GF085 (40ns rise, 25ns fall versus 130ns rise, 50ns fall) represent improved performance that is backward-compatible with designs specified for the IR2302SPBF. Faster switching reduces power dissipation and electromagnetic interference. No circuit modifications are required to accommodate this improvement.

Q: What is the bootstrap voltage rating and how does it apply to both parts?

A: Both the IR2302SPBF and FAN7080MX-GF085 support a maximum bootstrap voltage of 600V. This rating defines the maximum voltage differential between the high-side and low-side gate driver outputs, typical for half-bridge IGBT and MOSFET driver applications. Both parts are rated identically for this critical parameter.
