Electrical Compatibility Requirements:

• Drain-to-source voltage (Vdss) equal to or greater than 75V
• Continuous drain current (Id) equal to or greater than 42A at 25°C
• Gate threshold voltage (Vgs(th)) within compatible range (4V nominal)
• Maximum gate voltage (Vgs) rating of ±20V
• Operating temperature range spanning -55°C to 175°C

Mechanical Compatibility Requirements:

• Package type: IPAK (TO-251AA) through-hole configuration
• Pin configuration: TO-251-3 Short Leads
• Mounting type: Through hole

Compliance Considerations:

• RoHS compliance status
• REACH compliance status
• Moisture sensitivity level (MSL)

The IRFU3607PBF meets all electrical and mechanical substitution criteria while offering improved performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The IRFU3607PBF is a direct substitute for the IRFU2407 based on the following engineering criteria:

Electrical Compatibility: The IRFU3607PBF exceeds the minimum electrical requirements of the IRFU2407. With a continuous drain current rating of 56A compared to 42A, and improved on-state resistance of 9mOhm versus 26mOhm, the substitute part provides enhanced performance headroom. Both devices share identical drain-to-source voltage ratings (75V), gate threshold voltage (4V), and maximum gate voltage (±20V), ensuring direct functional compatibility in existing circuit designs.

Mechanical Compatibility: Both devices utilize the IPAK (TO-251AA) through-hole package with identical pin configurations and mounting requirements. No PCB layout modifications are necessary for substitution.

Compliance and Product Status: The IRFU3607PBF holds active product status with ROHS3 compliance, whereas the IRFU2407 is obsolete and RoHS non-compliant. Selection of the IRFU3607PBF ensures compliance with current environmental regulations and guarantees long-term component availability.

Thermal Performance: The IRFU3607PBF provides superior thermal performance with a maximum power dissipation rating of 140W compared to 110W for the IRFU2407, offering additional thermal margin in power-dissipative applications.

Frequently Asked Questions (FAQ)

Q: Can the IRFU3607PBF be used as a direct replacement for the IRFU2407 without circuit modifications?

A: Yes. The IRFU3607PBF is electrically and mechanically compatible with the IRFU2407. Both devices share identical voltage ratings (75V Vdss), gate threshold voltage (4V), and package configuration (IPAK TO-251AA). The substitute part exceeds the current and power dissipation requirements of the original device, making it suitable for direct substitution in existing designs.

Q: What are the key performance improvements of the IRFU3607PBF over the IRFU2407?

A: The IRFU3607PBF provides three primary improvements: (1) increased continuous drain current rating of 56A versus 42A, (2) reduced on-state resistance of 9mOhm versus 26mOhm, resulting in lower conduction losses, and (3) increased power dissipation capability of 140W versus 110W. These enhancements provide improved thermal performance and current handling capacity.

Q: Are there any package or pinout differences between these devices?

A: No. Both the IRFU2407 and IRFU3607PBF use the IPAK (TO-251AA) through-hole package with identical TO-251-3 short lead configurations. No PCB layout changes or rework is required for substitution.

Q: What is the significance of the IRFU2407 being classified as obsolete?

A: Obsolete status indicates that the IRFU2407 is no longer manufactured and existing inventory is limited. The IRFU3607PBF, classified as active, ensures continued availability and long-term supply chain reliability for new production and field replacements.

Q: Does the IRFU3607PBF meet current environmental compliance standards?

A: Yes. The IRFU3607PBF is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The original IRFU2407 is RoHS non-compliant, making the substitute part necessary for compliance with modern manufacturing and environmental standards.

Q: Are the gate charge characteristics significantly different between these devices?

A: The IRFU3607PBF has a lower gate charge of 84nC at 10V compared to 110nC for the IRFU2407. This reduction improves switching speed and reduces gate drive power requirements, providing additional performance benefits in switching applications.

Q: What is the moisture sensitivity level for both devices?

A: Both the IRFU2407 and IRFU3607PBF have a moisture sensitivity level (MSL) of 1, indicating unlimited shelf life without moisture control requirements during storage and handling.
