IRL530 N-Channel MOSFET 100V 15A TO-220AB Equivalent & Substitute Parts

Part Overview

The IRL530 is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 100V drain-to-source voltage with 15A continuous drain current at 25°C. The device is housed in a TO-220AB through-hole package and dissipates a maximum of 88W at the case temperature. The IRL530 is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute parts are selected based on matching or exceeding the electrical performance parameters while maintaining compatibility with the TO-220-3 package footprint and thermal characteristics required for the application.

Substitute Part Grouping Explanation

Substitute parts for the IRL530 are grouped based on the following electrical and mechanical criteria:

Critical Matching Parameters:

Drain to Source Voltage (Vdss): 100V minimum
Package / Case: TO-220-3 through-hole configuration
FET Type: N-Channel MOSFET technology
Operating Temperature Range: -55°C to 175°C or compatible subset

Performance Consideration Parameters:

Continuous Drain Current (Id): 15A or higher
Power Dissipation (Max): 88W or higher
Rds On (Max): 160 mOhm or lower (lower is acceptable)
Gate Charge (Qg): 28 nC or lower (lower is acceptable)

Substitutes are classified into two categories:

Direct Equivalent (IRL530PBF): Identical electrical specifications with improved product status (Active vs. Obsolete) and enhanced RoHS compliance.
Functional Alternatives: Parts meeting or exceeding the critical parameters with variations in secondary characteristics. These include the IRF520NPBF, IRF540ZPBF, IRL520NPBF, and RFP12N10L, each offering different trade-offs in current capacity, on-resistance, and gate charge.

Engineering Selection Recommendations

Primary Recommendation: IRL530PBF

The IRL530PBF is the direct equivalent of the IRL530, offering identical electrical specifications including 100V Vdss, 15A continuous drain current, 160 mOhm Rds On, and 88W power dissipation. The IRL530PBF is classified as Active with ROHS3 compliance, eliminating obsolescence concerns while maintaining full compatibility with existing designs. This part is the preferred choice for direct replacement in new procurement and redesign efforts.

Secondary Recommendations:

IRF540ZPBF is suitable for applications requiring higher current capacity (36A) or lower on-resistance (26.5 mOhm). This part exceeds the IRL530 specifications and is appropriate for designs where thermal margin or current headroom is beneficial. The higher gate charge (63 nC) may require driver circuit evaluation.

RFP12N10L provides a balanced alternative with 12A continuous drain current, 200 mOhm Rds On, and 60W power dissipation. This part is suitable for applications where the IRL530 current rating is not fully utilized. The maximum operating temperature is limited to 150°C, which is 25°C lower than the IRL530 specification.

IRF520NPBF is suitable only for applications where the required continuous drain current does not exceed 9.7A. The reduced current capacity and power dissipation (48W) make this part appropriate for lower-power variants of the original design.

IRL520NPBF is classified as Not For New Designs and is not recommended for new procurement or design efforts, despite its Active RoHS3 compliance status.

Frequently Asked Questions (FAQ)

Q: Can the IRL530PBF be used as a direct replacement for the IRL530?

A: Yes. The IRL530PBF is electrically and mechanically identical to the IRL530, with the same 100V Vdss, 15A continuous drain current, 160 mOhm Rds On, and 88W power dissipation. The IRL530PBF is Active and ROHS3 compliant, making it the preferred direct replacement.

Q: What is the difference between the IRL530 and IRF540ZPBF?

A: The IRF540ZPBF has a higher continuous drain current (36A vs. 15A) and significantly lower on-resistance (26.5 mOhm vs. 160 mOhm). Both devices share the same 100V Vdss rating and TO-220-3 package. The IRF540ZPBF is suitable for applications requiring higher current capacity or lower power dissipation. The gate charge is higher (63 nC vs. 28 nC), which may affect switching speed in driver-limited circuits.

Q: Can the RFP12N10L replace the IRL530 in all applications?

A: The RFP12N10L can replace the IRL530 only in applications where the continuous drain current requirement does not exceed 12A and the maximum operating temperature does not exceed 150°C. The IRL530 is rated to 175°C, providing a 25°C thermal margin advantage. The RFP12N10L has identical on-resistance (200 mOhm) and similar gate charge characteristics, making it suitable for lower-power or thermally constrained designs.

Q: Are all substitute parts available in the same TO-220-3 package?

A: Yes. All substitute parts listed are housed in the TO-220-3 through-hole package, ensuring mechanical and thermal interface compatibility with the IRL530 footprint.

Q: What is the significance of the Product Status field?

A: Product Status indicates the manufacturer's support level. Active parts are in full production and recommended for new designs. Obsolete parts are no longer manufactured. Not For New Designs indicates the part is available but not recommended for new procurement. The IRL530PBF (Active) is preferred over the IRL530 (Obsolete) for ongoing support and availability.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance does not affect electrical performance. ROHS3 compliance indicates the part meets Restriction of Hazardous Substances requirements and is suitable for applications with environmental or regulatory constraints. The IRL530 is RoHS non-compliant, while all substitute parts are ROHS3 compliant.

Q: Can the IRF520NPBF be used in high-current applications?

A: No. The IRF520NPBF is rated for 9.7A continuous drain current, which is below the IRL530 specification of 15A. This part is suitable only for applications where the required current does not exceed 9.7A. For applications requiring 15A or higher, the IRL530PBF or IRF540ZPBF are appropriate choices.
