IRL8113S N-Channel 30V 105A MOSFET Equivalent & Substitute Parts

Part Overview

The IRL8113S is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 30V drain-to-source voltage with 105A continuous drain current at 25°C. This device is housed in a D2PAK surface mount package and is designed for high-current switching applications. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. Substitute parts must maintain compatibility across voltage ratings, current handling capability, thermal characteristics, and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IRL8113S is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Drain-to-Source Voltage (Vdss): Must equal or exceed 30V
• Package Type: Must be D2PAK (TO-263-3) surface mount
• Mounting Type: Must be surface mount
• Operating Temperature Range: Must span -55°C to 175°C minimum
• Gate Voltage Rating (Vgs Max): Must support ±20V

Performance Matching Criteria:

• Continuous Drain Current (Id): Substitute must support the application's current requirement
• On-State Resistance (Rds On): Lower values indicate improved efficiency
• Power Dissipation: Must be adequate for thermal management in the application
• Gate Charge (Qg): Affects switching speed and driver requirements

Two substitute parts are identified based on these parameters. The PSMN4R3-30BL,118 provides near-equivalent current handling (100A vs. 105A) with improved on-state resistance (4.1mOhm vs. 6mOhm) and active product status. The PSMN017-30BL,118 offers reduced current rating (32A) and is suitable only for applications with lower current demands.

Engineering Selection Recommendations

Primary Substitute: PSMN4R3-30BL,118

The PSMN4R3-30BL,118 is the preferred substitute for the IRL8113S. This part maintains electrical equivalence across all critical parameters: identical 30V Vdss rating, near-equivalent 100A continuous drain current (within 5% of the original 105A specification), and superior on-state resistance of 4.1mOhm compared to 6mOhm. The device is housed in the same D2PAK package and supports the full -55°C to 175°C operating temperature range. Critically, the PSMN4R3-30BL,118 carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. Power dissipation of 103W is adequate for thermal management in applications designed for the 110W IRL8113S.

Secondary Substitute: PSMN017-30BL,118

The PSMN017-30BL,118 is suitable only for applications where continuous drain current does not exceed 32A. While this part shares the 30V Vdss rating, D2PAK package, and full temperature range, its 32A current rating represents a significant reduction from the IRL8113S specification. This part is appropriate for lower-power variants or redesigned circuits with reduced current demands. The PSMN017-30BL,118 also carries ROHS3 compliance but is classified as obsolete.

Compliance Considerations:

Both Nexperia substitutes are ROHS3 compliant, whereas the original IRL8113S is non-compliant. This compliance upgrade supports modern procurement and environmental standards. Both substitutes maintain REACH unaffected status and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the PSMN4R3-30BL,118 directly replace the IRL8113S without circuit modifications?

A: The PSMN4R3-30BL,118 is electrically and mechanically compatible with the IRL8113S. Both devices share identical 30V Vdss rating, D2PAK package, and -55°C to 175°C operating range. The 100A continuous current rating of the PSMN4R3-30BL,118 is within 5% of the IRL8113S 105A specification. The improved on-state resistance (4.1mOhm vs. 6mOhm) reduces power dissipation, which is beneficial for thermal management. No circuit modifications are required for direct substitution in applications designed for the IRL8113S.

Q: What is the significance of the lower on-state resistance in the PSMN4R3-30BL,118?

A: On-state resistance (Rds On) directly affects power dissipation and efficiency. The PSMN4R3-30BL,118 exhibits 4.1mOhm compared to 6mOhm in the IRL8113S. At 100A continuous current, this 32% reduction in Rds On translates to lower I²R losses and reduced thermal stress on the device. This improvement enhances reliability and may allow for more compact thermal management solutions.

Q: Why is the PSMN017-30BL,118 listed as a substitute if its current rating is significantly lower?

A: The PSMN017-30BL,118 is listed as a substitute only for applications where the circuit has been redesigned or where the actual current requirement does not exceed 32A. It maintains the same 30V voltage rating and D2PAK package, making it mechanically compatible. However, its 32A current rating makes it unsuitable for applications requiring the full 105A capability of the IRL8113S. Selection of this part requires verification that application current demands are within its 32A specification.

Q: Are there differences in gate charge between the substitutes?

A: Yes. The IRL8113S has a gate charge of 35nC at 4.5V, the PSMN4R3-30BL,118 has 41.5nC at 10V, and the PSMN017-30BL,118 has 10.7nC at 10V. Gate charge affects switching speed and driver circuit requirements. The PSMN4R3-30BL,118's slightly higher gate charge may require marginally faster gate drivers but remains within acceptable limits for most applications. The PSMN017-30BL,118's lower gate charge indicates faster switching characteristics suitable for lower-current applications.

Q: What is the impact of input capacitance differences?

A: Input capacitance (Ciss) affects gate drive circuit design and switching transients. The IRL8113S has 2840pF at 15V, the PSMN4R3-30BL,118 has 2400pF, and the PSMN017-30BL,118 has 552pF. The PSMN4R3-30BL,118's lower Ciss provides slightly faster switching response with reduced gate driver stress. The PSMN017-30BL,118's significantly lower Ciss reflects its lower current rating and is appropriate for lower-power applications.

Q: Does RoHS compliance affect substitution decisions?

A: The PSMN4R3-30BL,118 and PSMN017-30BL,118 are both ROHS3 compliant, whereas the IRL8113S is non-compliant. For new designs or procurement requiring RoHS compliance, the Nexperia substitutes are mandatory. For legacy systems, compliance requirements depend on application context and regulatory jurisdiction. Both substitutes maintain REACH unaffected status, ensuring no additional regulatory burden.

Q: Is the D2PAK package identical across all three parts?

A: Yes. All three parts—IRL8113S, PSMN4R3-30BL,118, and PSMN017-30BL,118—use the D2PAK package (TO-263-3 with 2 leads plus tab). This ensures mechanical and thermal compatibility on printed circuit boards. No PCB layout modifications are required for substitution.

Q: What inventory considerations apply to these substitutes?

A: The PSMN4R3-30BL,118 has 10,750 pieces in stock (active product status), ensuring long-term availability. The PSMN017-30BL,118 has 2,767 pieces available but is classified as obsolete. The original IRL8113S has 2,077 pieces in stock but is also obsolete. For new designs, the PSMN4R3-30BL,118 is the recommended choice due to active product status and superior inventory position.
