IRF7307PBF Equivalent & Substitute Parts

Part Overview

The IRF7307PBF is a dual MOSFET array manufactured by Infineon Technologies, integrating N-channel and P-channel MOSFETs in a single 8-SOIC package. This device is designed for logic-level gate drive applications with a maximum drain-source voltage rating of 20V and combined current ratings of 5.2A (N-channel) and 4.3A (P-channel). The IRF7307PBF is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain compatibility with existing circuit designs while meeting the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the IRF7307PBF is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Drain to Source Voltage (Vdss): Must equal 20V
• Package / Case: Must be 8-SOIC (0.154", 3.90mm Width)
• Configuration: Must be N and P-Channel dual MOSFET array
• FET Feature: Must support Logic Level Gate operation
• Operating Temperature Range: Must span -55°C to 150°C (TJ)
• RoHS3 Compliance: Required
• Moisture Sensitivity Level (MSL): Must be 1 (Unlimited)

Performance Compatibility Parameters:

• Current ratings (Id): Substitute must meet or exceed 5.2A (N-channel) and 4.3A (P-channel)
• Rds On: Substitute must not exceed 50mOhm at specified conditions
• Gate Charge (Qg): Lower values indicate improved switching performance
• Power dissipation: Substitute rating must support application requirements

The DMC2020USD-13 from Diodes Incorporated meets all mandatory equivalence criteria and demonstrates superior electrical performance characteristics, including higher continuous drain current ratings (7.8A/6.3A) and lower on-resistance (20mOhm).

Engineering Selection Recommendations

Primary Substitute: DMC2020USD-13

The DMC2020USD-13 is the qualified substitute for the IRF7307PBF based on the following engineering criteria:

1. Electrical Equivalence: Both devices maintain identical Vdss (20V), package configuration (8-SOIC), and operating temperature range (-55°C to 150°C). The DMC2020USD-13 exceeds the current ratings of the IRF7307PBF, providing 7.8A (N-channel) and 6.3A (P-channel) versus 5.2A and 4.3A respectively.

2. On-Resistance Performance: The DMC2020USD-13 demonstrates superior on-resistance characteristics at 20mOhm compared to the IRF7307PBF at 50mOhm, resulting in reduced power dissipation and improved thermal performance in switching applications.

3. Switching Characteristics: Gate charge is reduced to 11.6nC in the DMC2020USD-13 versus 20nC in the IRF7307PBF, indicating faster switching transitions and lower gate drive power requirements.

4. Compliance and Availability: The DMC2020USD-13 maintains ROHS3 compliance, MSL 1 rating, and active product status with confirmed inventory availability (16,949 pieces), ensuring supply chain continuity.

5. Package Compatibility: Both devices utilize identical 8-SOIC (0.154", 3.90mm Width) packaging, enabling direct PCB footprint compatibility without layout modifications.

Application Suitability: The DMC2020USD-13 is suitable for direct replacement in applications where the IRF7307PBF was originally specified, with the additional benefit of improved electrical performance margins.

Frequently Asked Questions (FAQ)

Q: Can the DMC2020USD-13 be used as a direct replacement for the IRF7307PBF in existing designs?

A: Yes. Both devices share identical Vdss (20V), package type (8-SOIC), configuration (N and P-Channel), and operating temperature range (-55°C to 150°C). The DMC2020USD-13 provides equal or superior electrical performance across all critical parameters, including higher continuous drain current ratings and lower on-resistance.

Q: What are the key differences between the IRF7307PBF and DMC2020USD-13?

A: The primary differences are: (1) Continuous drain current: DMC2020USD-13 provides 7.8A/6.3A versus IRF7307PBF 5.2A/4.3A; (2) On-resistance: DMC2020USD-13 is 20mOhm versus IRF7307PBF 50mOhm; (3) Gate charge: DMC2020USD-13 is 11.6nC versus IRF7307PBF 20nC; (4) Product status: DMC2020USD-13 is active while IRF7307PBF is discontinued.

Q: Are there any thermal or power dissipation considerations when substituting these devices?

A: The DMC2020USD-13 exhibits lower on-resistance (20mOhm versus 50mOhm), which reduces conduction losses and heat generation. This represents an improvement over the original IRF7307PBF design. Both devices operate across the same temperature range (-55°C to 150°C).

Q: Do both devices require identical PCB footprints?

A: Yes. Both the IRF7307PBF and DMC2020USD-13 use the 8-SOIC (0.154", 3.90mm Width) package, ensuring identical PCB footprint compatibility without layout modifications.

Q: What compliance certifications apply to the DMC2020USD-13?

A: The DMC2020USD-13 is ROHS3 compliant, REACH unaffected, and carries MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the IRF7307PBF.

Q: Is the DMC2020USD-13 currently available in inventory?

A: Yes. The DMC2020USD-13 is an active product with 16,949 pieces confirmed in stock, providing reliable supply chain availability compared to the discontinued IRF7307PBF.

Q: Are gate drive requirements different between these two devices?

A: The DMC2020USD-13 requires lower gate charge (11.6nC versus 20nC), resulting in reduced gate drive power consumption and faster switching transitions. Existing gate drive circuits designed for the IRF7307PBF will operate effectively with the DMC2020USD-13.
