IRFZ24 N-Channel MOSFET 60V 17A TO-220AB Equivalent & Substitute Parts

Part Overview

The IRFZ24 is an N-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) rated for 60V drain-to-source voltage with 17A continuous drain current at 25°C. This device is packaged in a Through Hole TO-220AB configuration and is designed for general-purpose switching and amplification applications requiring moderate power dissipation up to 60W.

The IRFZ24 carries an Obsolete product status. Locating equivalent or substitute components is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or repair requirements. Active alternatives with identical or comparable electrical characteristics are available from the same manufacturer and qualified third-party sources.

Substitute Part Grouping Explanation

Substitution of the IRFZ24 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Drain to Source Voltage (Vdss): Must equal or exceed 60V
• Continuous Drain Current (Id): Must equal or exceed 17A at 25°C
• On-State Drain Resistance (Rds On): Must not exceed 100mOhm at specified gate and drain conditions
• Gate Threshold Voltage (Vgs(th)): Must fall within ±20V maximum gate voltage specification
• Operating Temperature Range: Must support -55°C to 175°C (TJ)
• Mounting Type: Must be Through Hole
• Package / Case: Must be TO-220-3 compatible

Substitute Parts Identified:

1. IRFZ24PBF (Vishay Siliconix) – Direct manufacturer equivalent with identical electrical specifications and Active product status
2. STP16NF06 (STMicroelectronics) – Qualified alternative with comparable electrical performance and Active product status

Both substitute parts meet the primary substitution criteria. Differences in secondary parameters (Gate Charge, Input Capacitance, Power Dissipation) are within acceptable engineering tolerances for general-purpose switching applications.

Parameter Comparison

Engineering Selection Recommendations

IRFZ24PBF (Vishay Siliconix)

The IRFZ24PBF is the direct manufacturer equivalent of the obsolete IRFZ24. This part maintains identical electrical specifications across all critical parameters: 60V Vdss, 17A continuous drain current, 100mOhm Rds On, and 60W power dissipation. The IRFZ24PBF carries Active product status and is ROHS3 compliant, addressing regulatory requirements that the original IRFZ24 does not meet. This part is the preferred direct replacement for applications requiring exact electrical equivalence and is available in Tube packaging with 1485 pieces in stock.

STP16NF06 (STMicroelectronics)

The STP16NF06 is a qualified alternative from STMicroelectronics rated for 60V Vdss with 16A continuous drain current. While the drain current specification is 1A lower than the IRFZ24, the on-state drain resistance remains at 100mOhm, maintaining equivalent switching performance. The STP16NF06 features reduced gate charge (13nC versus 25nC) and lower input capacitance (315pF versus 640pF), resulting in faster switching characteristics and lower power dissipation (45W versus 60W). This part carries Active product status and ROHS3 compliance. The STP16NF06 is suitable for applications where the 16A current rating is sufficient and where improved switching speed is beneficial. Availability is high with 37100 pieces in stock.

Selection Basis:

• Both substitute parts are Active products with current manufacturing support
• Both parts are ROHS3 compliant, meeting modern regulatory standards
• Both parts maintain the TO-220-3 package configuration for direct mechanical compatibility
• IRFZ24PBF is selected for exact electrical equivalence
• STP16NF06 is selected for applications where 16A current capacity is acceptable and improved switching characteristics are advantageous

Frequently Asked Questions (FAQ)

Q: Can the IRFZ24PBF be used as a direct replacement for the IRFZ24?

A: Yes. The IRFZ24PBF is the direct manufacturer equivalent with identical electrical specifications. Both parts share the same 60V Vdss, 17A continuous drain current, 100mOhm Rds On, and 60W power dissipation. The primary difference is product status: IRFZ24PBF is Active while IRFZ24 is Obsolete. The IRFZ24PBF is ROHS3 compliant, whereas the IRFZ24 is not.

Q: Is the STP16NF06 a suitable replacement if my application requires 17A continuous drain current?

A: The STP16NF06 is rated for 16A continuous drain current, which is 1A lower than the IRFZ24 specification. Suitability depends on your actual circuit current requirements. If your design operates at or below 16A, the STP16NF06 is acceptable. If your design requires the full 17A capability, the IRFZ24PBF is the appropriate choice.

Q: What are the advantages of the STP16NF06 over the IRFZ24PBF?

A: The STP16NF06 offers reduced gate charge (13nC versus 25nC) and lower input capacitance (315pF versus 640pF), resulting in faster switching speed and reduced gate drive power requirements. Power dissipation is lower at 45W versus 60W. These characteristics make the STP16NF06 advantageous in high-frequency switching applications or designs with limited thermal headroom.

Q: Are both substitute parts compatible with the TO-220-3 package footprint?

A: Yes. Both IRFZ24PBF and STP16NF06 are packaged in TO-220-3 configuration, which is mechanically and electrically compatible with the original IRFZ24 TO-220AB package. Direct PCB mounting without modification is possible.

Q: What is the difference between IRFZ24 and IRFZ24PBF packaging?

A: The IRFZ24 is supplied in standard packaging, while the IRFZ24PBF is supplied in Tube packaging. Both parts use the same TO-220-3 case. Tube packaging is a standard industry format for component handling and storage. The electrical specifications are identical.

Q: Are there any compliance or regulatory differences between the substitute parts?

A: Yes. The IRFZ24 is RoHS non-compliant. Both IRFZ24PBF and STP16NF06 are ROHS3 compliant. Both substitute parts are REACH Unaffected and carry EAR99 ECCN classification, matching the original part. If your application requires RoHS compliance, both substitute parts meet this requirement.

Q: Can I use the STP16NF06 in a design originally specified for the IRFZ24?

A: The STP16NF06 can be used if your circuit current requirements do not exceed 16A and if the reduced power dissipation (45W versus 60W) is acceptable for your thermal design. The electrical characteristics are sufficiently similar for general-purpose switching applications. Verify that your specific application does not depend on the full 17A rating or 60W power dissipation capability.

Q: What is the inventory status of these substitute parts?

A: IRFZ24PBF has 1485 pieces in stock. STP16NF06 has 37100 pieces in stock. The original IRFZ24 has 2500 pieces in stock but carries Obsolete status. For new designs or long-term supply assurance, the substitute parts with Active status are recommended.
