NTP22N06 N-Channel MOSFET 60V 22A TO-220 Equivalent & Substitute Parts

Part Overview

The NTP22N06 is an N-Channel MOSFET manufactured by onsemi, rated for 60V drain-to-source voltage with 22A continuous drain current in a Through Hole TO-220 package. This device is classified as Obsolete, making identification of equivalent and substitute parts necessary for ongoing design support, maintenance, and production continuity. The part operates across a temperature range of -55°C to 175°C and dissipates up to 60W, suitable for switching and amplification applications requiring moderate power handling in standard through-hole form factors.

Substitute Part Grouping Explanation

Substitution of the NTP22N06 is determined by alignment across the following critical parameters:

Voltage Rating (Vdss): The substitute must support the same or higher drain-to-source voltage to ensure safe operation in the original circuit. The NTP22N06 operates at 60V; substitutes must meet or exceed this specification.

Current Rating (Id): The substitute must deliver equal or greater continuous drain current at 25°C to maintain circuit performance. The NTP22N06 is rated for 22A; substitutes must support this current level or higher.

On-State Resistance (Rds On): Lower or equivalent on-state resistance ensures comparable power dissipation and thermal performance. The NTP22N06 exhibits 60mOhm at specified conditions; substitutes with equal or lower resistance are acceptable.

Package and Mounting: All substitutes must use the same Through Hole TO-220-3 package to ensure mechanical and electrical compatibility with existing PCB layouts and thermal management solutions.

Temperature Range: Operating temperature specifications must encompass the original -55°C to 175°C range to guarantee reliability across all environmental conditions.

The two substitute parts identified—IRLZ24NPBF and STP36NF06L—meet these criteria with specific trade-offs in current rating, power dissipation, and product status.

Engineering Selection Recommendations

STP36NF06L (STMicroelectronics) – Primary Substitute

The STP36NF06L is the preferred substitute for new designs and production continuity. It maintains the 60V voltage rating of the original NTP22N06, exceeds the current requirement with 30A continuous drain current, and delivers superior on-state resistance of 40mOhm at 15A. The device is classified as Active, ensuring long-term availability and supply chain stability. Full ROHS3 compliance satisfies modern regulatory requirements. The 70W power dissipation rating provides thermal margin above the original 60W specification. All electrical parameters fall within acceptable substitution ranges, and the TO-220-3 package ensures direct mechanical compatibility.

IRLZ24NPBF (Infineon Technologies) – Secondary Substitute

The IRLZ24NPBF serves as an alternative where current requirements can be reduced to 18A. The device operates at 55V, which is 5V below the original specification and may present limitations in circuits designed for full 60V headroom. The on-state resistance matches the original at 60mOhm, and the lower gate charge (15nC) provides faster switching characteristics. The product status is classified as Not For New Designs, indicating limited future support. ROHS3 compliance is achieved. This substitute is suitable only for applications where the 18A current rating and 55V voltage rating are acceptable trade-offs.

Product Status Consideration

The NTP22N06 is Obsolete. The STP36NF06L, with Active status, provides the most reliable path for design continuity and future production. The IRLZ24NPBF, classified as Not For New Designs, offers a transitional option but does not provide the same long-term support assurance.

Frequently Asked Questions (FAQ)

Q: Can the IRLZ24NPBF directly replace the NTP22N06 in all applications?

A: The IRLZ24NPBF is not a direct replacement for all applications. While it shares the same on-state resistance and package, it is rated for 55V (5V lower than the NTP22N06) and 18A continuous current (4A lower). Applications operating at or near 60V or requiring 22A continuous current must use the STP36NF06L instead.

Q: Why is the STP36NF06L recommended over the IRLZ24NPBF?

A: The STP36NF06L maintains the original 60V voltage rating, exceeds the current requirement with 30A, and is classified as Active for long-term availability. The IRLZ24NPBF is rated for only 55V and 18A, with a product status of Not For New Designs, limiting its suitability for new or ongoing production.

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

A: Yes. All three devices—NTP22N06, IRLZ24NPBF, and STP36NF06L—use the TO-220-3 package and Through Hole mounting type. No PCB modifications are required for mechanical or thermal interface compatibility.

Q: What is the impact of lower gate charge in the IRLZ24NPBF?

A: The IRLZ24NPBF exhibits lower gate charge (15nC at 5V versus 32nC at 10V for the NTP22N06), resulting in faster switching transitions and reduced gate drive power requirements. This is an advantage in high-frequency switching applications but does not affect DC operating characteristics.

Q: Does the lower on-state resistance of the STP36NF06L provide any advantage?

A: Yes. The STP36NF06L exhibits 40mOhm on-state resistance at 15A, compared to 60mOhm for the NTP22N06 at 11A. Lower on-state resistance reduces conduction losses and heat dissipation, improving overall circuit efficiency and thermal performance.

Q: Are there compliance differences between the three devices?

A: Yes. The NTP22N06 is RoHS non-compliant. Both the IRLZ24NPBF and STP36NF06L are ROHS3 compliant, meeting modern environmental and regulatory standards. For applications subject to RoHS requirements, only the IRLZ24NPBF or STP36NF06L are acceptable.

Q: Can the STP36NF06L be used in applications originally designed for the NTP22N06?

A: Yes. The STP36NF06L is a direct functional substitute. It meets or exceeds all critical electrical parameters: 60V voltage rating, 30A current rating (exceeding the 22A requirement), equivalent or superior on-state resistance, and identical temperature range. The higher current and power ratings provide design margin without introducing compatibility issues.

Q: What is the significance of the "Not For New Designs" status of the IRLZ24NPBF?

A: This status indicates that the manufacturer does not recommend the IRLZ24NPBF for new product development. While existing inventory may be available, long-term supply and support are not guaranteed. For new designs or production continuity, the STP36NF06L is the appropriate choice.
