Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRL6372PBF is determined by the following critical parameters:

Primary Compatibility Criteria:

• Drain-Source Voltage (Vdss): Must equal 30V
• Configuration: Must be 2 N-Channel (Dual) in 8-SOIC package
• Mounting Type: Surface Mount
• Package Dimensions: 8-SOIC (0.154", 3.90mm Width)
• Operating Temperature Range: -55°C to 150°C (TJ)

Secondary Performance Parameters:

• Continuous Drain Current (Id): Minimum 8.1A at 25°C
• On-Resistance (Rds On): Lower or equivalent values preferred
• Gate Threshold Voltage (Vgs(th)): Logic level operation (typically 1V to 2.6V)
• Maximum Power Dissipation: Minimum 2W

Compliance Requirements:

• RoHS3 Compliant
• MSL 1 (Unlimited)
• REACH Unaffected status

All substitute parts listed meet these core electrical and mechanical parameters. Variations in secondary parameters (gate charge, input capacitance, on-resistance) are acceptable within the scope of dual N-channel 30V MOSFET array functionality.

Engineering Selection Recommendations

For Active Product Status (Recommended for New Designs):

The following substitute parts maintain active product status and are suitable for new design implementations:

• AO4818B (Alpha & Omega Semiconductor): Meets all primary electrical parameters with 8A continuous drain current. Active product status ensures long-term availability and supply chain stability.

• DMN3015LSD-13 (Diodes Incorporated): Exceeds drain current specification at 8.4A with superior on-resistance performance (15 mOhm). Active status with established manufacturing support.

• SI4214DDY-T1-GE3 (Vishay Siliconix): Provides 8.5A continuous drain current with TrenchFET® technology. Active product with logic level gate feature matching the original specification.

• STS8DN3LLH5 (STMicroelectronics): Delivers 10A continuous drain current with STripFET™ V technology. Active product status with enhanced power dissipation capability (2.7W).

For Existing Design Maintenance (Legacy Support):

Parts with "Not For New Designs" status remain electrically compatible for replacement in existing applications but should not be selected for new circuit designs:

• AO4842 (Alpha & Omega Semiconductor)
• SH8KA4TB (Rohm Semiconductor)
• STS10DN3LH5 (STMicroelectronics)

Compliance Verification:

All listed substitute parts maintain RoHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status, matching the original IRL6372PBF regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I directly replace IRL6372PBF with any of the listed substitute parts?

A: Direct replacement is possible only if the substitute part meets the minimum electrical specifications required by your circuit design. All listed parts share the same 30V Vdss rating, dual N-channel configuration, and 8-SOIC package. However, variations in on-resistance, gate charge, and input capacitance may affect circuit performance. Verify that the substitute part's electrical characteristics are compatible with your specific application requirements.

Q: What is the difference between "Active" and "Not For New Designs" product status?

A: "Active" status indicates the manufacturer continues production and supports the part for new circuit designs. "Not For New Designs" status means the manufacturer has discontinued active development but may still supply existing inventory. For new designs, select only parts with "Active" status to ensure long-term availability and manufacturer support.

Q: Are all substitute parts in the same package?

A: Yes, all substitute parts use 8-SOIC packaging with 0.154" (3.90mm) width, ensuring mechanical compatibility with the original IRL6372PBF footprint. However, verify PCB layout compatibility with your specific design before implementation.

Q: How do I determine which substitute part is best for my application?

A: Selection depends on your circuit's specific requirements. If your design requires minimum on-resistance, DMN3015LSD-13 offers superior performance at 15 mOhm. If maximum current handling is critical, STS8DN3LLH5 and STS10DN3LH5 provide 10A capability. For logic level gate operation matching the original specification, AO4818B and SI4214DDY-T1-GE3 are optimal choices.

Q: What is the significance of gate charge (Qg) differences between parts?

A: Gate charge affects switching speed and driver circuit requirements. Lower gate charge (IRL6372PBF at 11 nC, STS10DN3LH5 at 4.6 nC) enables faster switching with lower driver power consumption. Higher gate charge (DMN3015LSD-13 at 25.1 nC) may require more robust gate driver circuits but does not prevent substitution if your driver circuit is adequately rated.

Q: Can I use DMN3033LSDQ-13 as a substitute if my circuit only requires 6.9A?

A: Yes, DMN3033LSDQ-13 is electrically compatible if your circuit operates at or below 6.9A continuous drain current. However, this part provides lower current capability than the original 8.1A specification. Use this part only if your actual circuit current requirements are confirmed to be within its 6.9A rating.

Q: Are there any thermal considerations when substituting parts?

A: Maximum power dissipation ratings vary among substitute parts (1.2W to 3.1W). Ensure your thermal management design accommodates the substitute part's power dissipation characteristics. Parts with higher power ratings (SH8KA4TB at 3W, SI4214DDY-T1-GE3 at 3.1W) provide additional thermal margin in high-current applications.

Q: Do all substitute parts have the same RoHS and REACH compliance?

A: Yes, all listed substitute parts are RoHS3 compliant, MSL 1 (Unlimited), and REACH Unaffected, matching the original IRL6372PBF regulatory status. This ensures compliance with current environmental and safety standards across all substitute options.
