IRL530NSTRL N-Channel MOSFET 100V 17A Equivalent & Substitute Parts

Part Overview

The IRL530NSTRL is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 100V drain-to-source voltage with 17A continuous drain current in a D2PAK surface mount package. This part is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement continuity. The HEXFET series designation indicates advanced gate oxide technology for enhanced performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IRL530NSTRL is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss) must equal or exceed 100V
• Continuous Drain Current (Id) must meet or exceed 17A at 25°C
• On-state resistance (Rds On) must not exceed 100mOhm at specified gate voltage
• Gate threshold voltage (Vgs(th)) must be compatible with 2V maximum specification
• Operating temperature range must encompass -55°C to 175°C

Mechanical Compatibility Criteria:

• Package type must be D2PAK (TO-263-3) surface mount configuration
• Pin configuration must maintain electrical equivalence

Compliance Criteria:

• RoHS compliance status is evaluated for regulatory alignment
• Moisture sensitivity level (MSL) must be 1 (Unlimited) or equivalent

Two substitute parts are identified based on these parameters, each with distinct characteristics affecting application suitability.

Engineering Selection Recommendations

IRL530NSTRLPBF (Parametric Equivalent - Primary Selection)

The IRL530NSTRLPBF is the direct parametric equivalent to the obsolete IRL530NSTRL. This part maintains identical electrical specifications including 17A continuous drain current, 100mOhm on-state resistance at 10V gate voltage, and 34nC gate charge. The primary distinction is product status: IRL530NSTRLPBF is active and ROHS3 compliant, addressing regulatory requirements for new designs. Packaging differs only in delivery format (Cut Tape & Digi-Reel versus Tape & Reel), which does not affect electrical or mechanical compatibility. This part is recommended for direct replacement in applications where the original specification must be maintained without modification.

IRL530STRRPBF (Manufacturer Recommended - Conditional Selection)

The IRL530STRRPBF, manufactured by Vishay Siliconix, is an alternative from a different manufacturer within the same base product family (IRL530). This part meets the 100V voltage rating and maintains the same operating temperature range and D2PAK package configuration. However, electrical parameters differ: continuous drain current is 15A (versus 17A), on-state resistance is 160mOhm at 5V gate voltage (versus 100mOhm at 10V), and input capacitance is 930pF (versus 800pF). These differences result in higher conduction losses and reduced current capacity. This part is suitable only for applications where the 15A current rating and higher on-state resistance are acceptable within the circuit design margins. Both parts are ROHS3 compliant and active in production.

Frequently Asked Questions (FAQ)

Q: Can IRL530NSTRLPBF be used as a direct replacement for IRL530NSTRL?

A: Yes. The IRL530NSTRLPBF is a parametric equivalent with identical electrical specifications. The only differences are product status (active versus obsolete) and packaging format (Cut Tape/Digi-Reel versus Tape & Reel). Both are D2PAK surface mount packages with identical pin configuration and electrical performance.

Q: What are the limitations of using IRL530STRRPBF as a substitute?

A: The IRL530STRRPBF has lower continuous drain current (15A versus 17A) and higher on-state resistance (160mOhm at 5V versus 100mOhm at 10V). These differences increase power dissipation and reduce current capacity. Use this part only if circuit design margins accommodate the reduced current rating and higher conduction losses.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use the D2PAK (TO-263-3) surface mount package with identical pin configuration and mechanical dimensions. PCB footprints are interchangeable without modification.

Q: What is the significance of RoHS compliance differences?

A: The IRL530NSTRL is RoHS non-compliant, while IRL530NSTRLPBF and IRL530STRRPBF are ROHS3 compliant. For new designs or applications subject to RoHS regulations, the compliant alternatives must be selected. For legacy systems, non-compliant parts may remain acceptable depending on regional requirements.

Q: How do gate charge differences affect circuit design?

A: Gate charge (Qg) determines the energy required to switch the MOSFET. IRL530NSTRL and IRL530NSTRLPBF both specify 34nC at 5V, while IRL530STRRPBF specifies 28nC. Lower gate charge reduces driver power requirements and enables faster switching. The 6nC difference is typically negligible in most applications but should be verified in high-frequency switching circuits.

Q: What packaging format differences exist between the substitutes?

A: IRL530NSTRL and IRL530STRRPBF are supplied in Tape & Reel (TR) format for automated assembly. IRL530NSTRLPBF is available in Cut Tape (CT) and Digi-Reel format. These are delivery and handling formats only; electrical and mechanical specifications remain identical.

Q: Can these parts be intermixed in the same production batch?

A: IRL530NSTRL and IRL530NSTRLPBF can be intermixed without functional impact due to identical electrical specifications. IRL530STRRPBF should not be intermixed with the others in the same batch if current rating or on-state resistance specifications are critical to circuit performance, as parameter differences may cause performance variation.
