STP7NB60 Equivalent & Substitute Parts

Part Overview

The STP7NB60 is an N-Channel MOSFET manufactured by STMicroelectronics, rated for 600V drain-to-source voltage with 7.2A continuous drain current at 25°C. This device is housed in a TO-220-3 through-hole package and is part of the PowerMESH™ series. The STP7NB60 is classified as obsolete, making identification of equivalent substitute parts necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STP7NB60 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• FET Type: N-Channel topology must be maintained
• Drain to Source Voltage (Vdss): Substitute must equal or exceed 600V
• Current - Continuous Drain (Id): Substitute must equal or exceed 7.2A at 25°C
• Rds On (Max): Substitute must not exceed 1.2 Ohm at specified conditions
• Power Dissipation (Max): Substitute must equal or exceed 125W
• Operating Temperature: Substitute must support minimum 150°C junction temperature

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole
• Package / Case: TO-220-3 pinout configuration

The IRFB9N65APBF meets these substitution criteria with equal or superior electrical ratings and identical mechanical packaging.

Parameter Comparison

Engineering Selection Recommendations

The IRFB9N65APBF is a direct substitute for the STP7NB60 based on the following factors:

Electrical Performance: The IRFB9N65APBF exceeds all minimum electrical requirements of the STP7NB60. It provides 650V Vdss (50V margin above the 600V requirement), 8.5A continuous drain current (1.3A above the 7.2A requirement), and 167W power dissipation (42W above the 125W requirement). The on-resistance of 0.93 Ohm is superior to the 1.2 Ohm specification.

Mechanical Compatibility: Both devices use identical TO-220-3 through-hole packaging, ensuring direct pin-for-pin compatibility in existing PCB layouts.

Product Status and Compliance: The IRFB9N65APBF is classified as Active, providing long-term availability and supply chain stability. It is ROHS3 compliant, whereas the STP7NB60 is RoHS non-compliant. Both devices are REACH Unaffected and classified under ECCN EAR99.

Temperature Range: The IRFB9N65APBF supports the required 150°C maximum junction temperature and extends the lower operating limit to −55°C, providing enhanced thermal flexibility.

Frequently Asked Questions (FAQ)

Q: Can the IRFB9N65APBF directly replace the STP7NB60 in existing designs?

A: Yes. The IRFB9N65APBF is a direct substitute with identical TO-220-3 pinout and superior electrical ratings across all critical parameters. No PCB modifications are required.

Q: What are the key differences between these two devices?

A: The IRFB9N65APBF provides higher voltage rating (650V vs. 600V), higher current capacity (8.5A vs. 7.2A), lower on-resistance (0.93 Ohm vs. 1.2 Ohm), and higher power dissipation capability (167W vs. 125W). The IRFB9N65APBF is also Active status with ROHS3 compliance, whereas the STP7NB60 is Obsolete and RoHS non-compliant.

Q: Are there any thermal considerations when substituting these parts?

A: The IRFB9N65APBF has superior thermal performance due to lower on-resistance and higher power dissipation rating. Both devices support 150°C maximum junction temperature. The IRFB9N65APBF extends the lower operating temperature to −55°C, providing wider thermal operating range.

Q: What is the significance of the TO-220-3 package designation?

A: TO-220-3 specifies a three-lead through-hole package with standardized pin spacing and mounting configuration. Both the STP7NB60 and IRFB9N65APBF use this identical package, ensuring mechanical and electrical compatibility without design modification.

Q: Why is the STP7NB60 classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The IRFB9N65APBF, classified as Active, provides a current-production alternative with equivalent or superior performance characteristics.

Q: Does RoHS compliance affect substitution decisions?

A: RoHS compliance is a regulatory and procurement consideration. The IRFB9N65APBF is ROHS3 compliant, making it suitable for applications requiring RoHS-compliant components. The STP7NB60 is RoHS non-compliant and may not meet current regulatory requirements for new designs.
