IRL520L N-Channel MOSFET 100V 9.2A TO-262-3

Part Overview

The IRL520L is an N-Channel MOSFET rated for 100V drain-to-source voltage with a continuous drain current of 9.2A at 25°C. This device is housed in a TO-262-3 package and is designed for through-hole mounting applications requiring moderate power dissipation up to 60W. The IRL520L is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRL520L is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Drain-to-source voltage rating (Vdss): 100V
• Continuous drain current (Id): 9.2A at 25°C
• On-state resistance (Rds On): 270mOhm maximum at specified conditions
• Gate threshold voltage (Vgs(th)): 2V maximum
• Gate charge (Qg): 12nC maximum
• Power dissipation capability: 60W
• Operating temperature range: -55°C to 175°C

Mechanical Equivalence Criteria:

• Package type: TO-262-3
• Mounting configuration: Through Hole
• Lead configuration: TO-262-3 Long Leads, I2PAK, TO-262AA

The IRL520LPBF is a parametric equivalent that maintains identical electrical specifications and package configuration while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The IRL520LPBF is a direct parametric equivalent to the IRL520L across all electrical and mechanical specifications. Selection between these parts is determined by product lifecycle and regulatory requirements:

IRL520L (Obsolete): Suitable only for legacy system maintenance where existing inventory is available and no new procurement is required. RoHS non-compliance restricts use in applications subject to RoHS3 regulations.

IRL520LPBF (Active): Recommended for all new designs and ongoing procurement. This part maintains identical electrical performance and package compatibility while offering active product status and ROHS3 compliance. The tube packaging format provides standard handling and storage benefits for production environments.

Both parts are manufactured by Vishay Siliconix and share the same base product number (IRL520), confirming parametric equivalence. Selection should be based on product availability, compliance requirements, and procurement timeline.

Frequently Asked Questions (FAQ)

Q: Can IRL520LPBF be used as a direct replacement for IRL520L in existing designs?

A: Yes. The IRL520LPBF is a parametric equivalent with identical electrical specifications (Vdss, Id, Rds On, Vgs(th), Qg, power dissipation, and operating temperature range) and the same TO-262-3 through-hole package. No circuit modifications are required.

Q: What is the primary difference between IRL520L and IRL520LPBF?

A: The IRL520L is obsolete with RoHS non-compliance, while the IRL520LPBF is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical. Packaging differs (bulk versus tube).

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts have identical power dissipation ratings (60W), operating temperature ranges (-55°C to 175°C), and all electrical parameters including on-state resistance, gate charge, and drain current specifications.

Q: Is the TO-262-3 package compatible with existing PCB layouts designed for IRL520L?

A: Yes. Both parts use the same TO-262-3 package with TO-262-3 Long Leads, I2PAK, TO-262AA configuration. Through-hole mounting is identical, ensuring direct PCB compatibility.

Q: What compliance certifications apply to each part?

A: IRL520L carries no RoHS compliance. IRL520LPBF is ROHS3 compliant. Both parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: Should I use IRL520L inventory for new production?

A: No. For new production, use IRL520LPBF to ensure compliance with current regulatory requirements and to benefit from active product support. Reserve IRL520L inventory for legacy system maintenance only.
