Engineering Selection Recommendations

IRL540NSTRLPBF (Infineon Technologies)

This substitute provides the highest continuous drain current rating at 36A (Tc), exceeding the original specification. The device maintains identical Vdss (100V) and compatible gate threshold voltage (2V @ 250µA). The lower RDS(on) of 44 mOhm @ 18A, 10V offers improved efficiency compared to the original 77 mOhm specification. All compliance certifications match the original part, including RoHS3 compliance and MSL 1 rating. This part is suitable for applications requiring higher current capacity within the same voltage class and package footprint.

BUK9675-100A,118 (Nexperia USA Inc.)

This substitute is rated for 23A continuous drain current (Tc), which is lower than the original 28A specification. The device maintains 100V Vdss and compatible gate threshold voltage (2V @ 1mA). The RDS(on) of 72 mOhm @ 10A, 10V is comparable to the original specification. This part carries AEC-Q101 automotive qualification and REACH Unaffected status in addition to RoHS3 compliance. Selection of this part is appropriate for applications where the 23A current rating is sufficient and automotive-grade qualification is required.

IRF530NSTRLPBF (Infineon Technologies)

This substitute is rated for 17A continuous drain current (Tc), which is lower than the original 28A specification. The device maintains 100V Vdss but has a higher gate threshold voltage of 4V @ 250µA compared to the original 2V specification. The RDS(on) of 90 mOhm @ 9A, 10V is higher than the original specification. This part is suitable only for applications where the 17A current rating and higher gate threshold voltage are compatible with the circuit design. All compliance certifications match the original part.

Frequently Asked Questions (FAQ)

Q: Can the BUK9675-100A,118 be used as a direct replacement for the IRL540STRLPBF?

A: The BUK9675-100A,118 is electrically compatible within the 100V Vdss class and shares the same D2PAK package. However, the continuous drain current rating is 23A compared to the original 28A. This substitute is appropriate only if the application current requirement does not exceed 23A (Tc). All other electrical parameters and compliance certifications are compatible.

Q: What is the primary difference between the IRL540NSTRLPBF and the original IRL540STRLPBF?

A: Both parts share the same base product number (IRL540) and are rated for 100V Vdss in the D2PAK package. The IRL540NSTRLPBF is manufactured by Infineon Technologies and offers a higher continuous drain current rating of 36A (Tc) compared to the original 28A, with improved RDS(on) performance. The original is manufactured by Vishay Siliconix. Both maintain identical operating temperature ranges and RoHS3 compliance.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts listed are packaged in the TO-263-3 (D2PAK) surface mount configuration with identical lead count and tab configuration. The mechanical footprint is compatible across all listed parts.

Q: What compliance certifications are common to all listed parts?

A: All parts, including the original IRL540STRLPBF and all substitutes, are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The BUK9675-100A,118 additionally carries AEC-Q101 automotive qualification and REACH Unaffected status.

Q: Which substitute part offers the best performance improvement over the original?

A: The IRL540NSTRLPBF provides the highest continuous drain current (36A vs. 28A) and the lowest RDS(on) (44 mOhm vs. 77 mOhm), resulting in improved current handling capacity and reduced power dissipation. This part is suitable for applications requiring higher performance within the same voltage and package specifications.

Q: Can the IRF530NSTRLPBF be used in applications designed for the IRL540STRLPBF?

A: The IRF530NSTRLPBF is compatible in terms of voltage rating (100V Vdss) and package type (D2PAK). However, the continuous drain current is limited to 17A (Tc), which is significantly lower than the original 28A specification. Additionally, the gate threshold voltage is 4V compared to the original 2V, which may require circuit design adjustments. This substitute is appropriate only for applications where both the reduced current rating and higher gate threshold voltage are acceptable.
