IRL520NPBF N-Channel 100V 10A MOSFET Equivalent & Substitute Parts

Part Overview

The IRL520NPBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 100V drain-to-source voltage and 10A continuous drain current in a TO-220AB through-hole package. This device is classified as "Not For New Designs," indicating it has reached end-of-life status. The HEXFET® series component is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Due to its obsolete product status, alternative N-Channel 100V MOSFETs in TO-220AB packaging are necessary for ongoing production, maintenance, and new circuit implementations. Substitute parts must maintain electrical compatibility within the specified parameter ranges while meeting current manufacturing and compliance standards.

Substitute Part Grouping Explanation

Substitution of the IRL520NPBF is determined by strict adherence to the following electrical and mechanical parameters:

Primary Compatibility Criteria:

Drain-to-Source Voltage (Vdss): Must equal or exceed 100V
Package Type: Must be TO-220AB through-hole configuration
FET Type: N-Channel MOSFET technology
Operating Temperature Range: Must span -55°C to 175°C minimum
Mounting: Through-hole only

Secondary Selection Parameters:

Continuous Drain Current (Id): Substitute must support minimum 10A at 25°C
On-State Resistance (Rds On): Lower values indicate improved performance; higher values acceptable if within thermal limits
Gate Threshold Voltage (Vgs(th)): Must be compatible with 10V gate drive voltage
Power Dissipation: Substitute must handle thermal requirements of application
Compliance: ROHS3 compliance and REACH unaffected status required

Substitute parts are grouped into two categories based on current rating capability: Standard Current Range (9.2A to 18A) and High Current Range (37A to 100A). Both categories maintain 100V Vdss rating and TO-220AB packaging, ensuring mechanical and electrical interchangeability within their respective performance tiers.

Engineering Selection Recommendations

For Direct Replacement (Minimum Current Requirement: 10A)

The IRL520PBF from Vishay Siliconix is the primary direct substitute. It maintains 100V Vdss rating, TO-220AB packaging, and Active product status. Although continuous drain current is rated at 9.2A (below the original 10A specification), this part is suitable for applications where the 10A rating represents a design margin rather than a hard requirement. The IRL520PBF carries ROHS3 compliance and unlimited MSL rating, matching the original part's environmental specifications.

For Higher Current Applications (10A to 18A Range)

The PHP18NQ10T,127 from Nexperia USA Inc. provides 18A continuous drain current with improved on-state resistance (90 mOhm versus 180 mOhm). This part is rated for 100V Vdss and uses TO-220AB packaging. However, it carries Obsolete product status, limiting its suitability for new production. The TrenchMOS™ series designation indicates advanced process technology.

For High Current Applications (Above 18A)

Multiple Nexperia parts support 37A to 100A continuous drain current: PSMN027-100PS,127 (37A), PSMN016-100PS,127 (57A), PSMN013-100PS,127 (68A), PSMN015-100P,127 (75A), PSMN009-100P,127 (75A), PSMN5R6-100PS,127 (100A), and PSMN7R0-100PS,127 (100A). All maintain 100V Vdss and TO-220AB packaging. These parts exhibit significantly lower on-state resistance values, reducing thermal dissipation in high-current circuits. Most carry Obsolete status; PSMN009-100P,127 is Active.

Active Product Status Priority

For new designs and ongoing production, IRL520PBF (Vishay Siliconix, Active) and PSMN009-100P,127 (NXP Semiconductors, Active) are the only substitute options with current manufacturing support. Both are ROHS3 compliant and REACH unaffected.

Compliance Verification

All listed substitutes maintain ROHS3 compliance and REACH unaffected status, matching the original IRL520NPBF environmental certifications. Operating temperature range spans -55°C to 175°C across all parts, ensuring thermal compatibility.

Frequently Asked Questions (FAQ)

Q: Can IRL520PBF replace IRL520NPBF in all applications?

A: IRL520PBF is electrically compatible for applications where 10A represents a design safety margin. The part is rated for 9.2A continuous drain current at 25°C, which is 8% below the original specification. Verify that your circuit operates safely at 9.2A maximum. Both parts share identical 100V Vdss rating, TO-220AB packaging, and -55°C to 175°C operating range. IRL520PBF is the only direct substitute with Active product status.

Q: What is the difference between Obsolete and Active product status?

A: Active parts are currently manufactured and available from distributors with ongoing supply. Obsolete parts are no longer produced; existing inventory may be available but supply is limited and will eventually deplete. For new designs, select only Active status parts: IRL520PBF or PSMN009-100P,127.

Q: Can I use a high-current part like PSMN009-100P,127 (75A) as a drop-in replacement for IRL520NPBF (10A)?

A: Yes, mechanically and electrically. The PSMN009-100P,127 maintains 100V Vdss and TO-220AB packaging. However, it exhibits significantly different electrical characteristics: 8.8 mOhm on-state resistance (versus 180 mOhm), 156 nC gate charge (versus 20 nC), and 8250 pF input capacitance (versus 440 pF). These differences affect switching speed, gate drive requirements, and circuit behavior. Use only if your circuit design accommodates these parameter variations.

Q: What does "Not For New Designs" mean for IRL520NPBF?

A: This designation indicates the part has reached end-of-life and Infineon no longer recommends it for new circuit designs. Existing inventory may be available, but long-term supply is not guaranteed. New designs should use Active status alternatives such as IRL520PBF or PSMN009-100P,127.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original IRL520NPBF environmental standard. REACH status is "REACH Unaffected" across all parts, indicating no restricted substances are present.

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

A: Gate charge determines the energy required to switch the MOSFET on and off. IRL520NPBF requires 20 nC at 5V gate voltage. Substitute parts vary: IRL520PBF requires 12 nC, while high-current parts require 21 to 156 nC. Higher gate charge increases switching losses and requires more robust gate drive circuitry. Verify your gate driver can supply the required charge for your selected substitute.

Q: Can I interchange parts with different Vgs(th) values?

A: Vgs(th) is the gate-source voltage at which the MOSFET begins to conduct. IRL520NPBF specifies 2V at 250µA, while most Nexperia substitutes specify 4V at 1mA. These different measurement conditions make direct comparison difficult. Verify that your gate drive voltage (typically 5V or 10V) is sufficient to fully enhance the selected substitute part. Both 2V and 4V threshold devices are compatible with standard 5V and 10V gate drive circuits.

Q: What is the TO-220AB package?

A: TO-220AB is a through-hole power package with three leads: Gate, Drain, and Source. The "AB" variant includes a mounting hole for heatsink attachment. All listed substitute parts use identical TO-220AB packaging, ensuring mechanical compatibility with existing PCB layouts and heatsink assemblies.

Q: Why do some parts list "Bulk" packaging while others list "Tube"?

A: Packaging format refers to the shipping and storage container. "Tube" indicates parts are supplied in plastic tubes (typically 50 or 100 pieces per tube), standard for component distribution. "Bulk" indicates loose parts supplied in larger quantities without individual tube packaging. Both formats contain identical components; packaging format does not affect electrical performance or compatibility.
