IXFV18N60PS N-Channel 600V 18A MOSFET Equivalent & Substitute Parts

Part Overview

The IXFV18N60PS is an N-Channel MOSFET manufactured by IXYS, rated for 600V drain-to-source voltage with 18A continuous drain current at 25°C. This device is packaged in PLUS-220SMD surface mount configuration and is designed for high-voltage switching applications requiring compact board integration.

The IXFV18N60PS is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing production requirements, field repairs, and design continuity where this part number is specified in existing schematics or bill of materials documentation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXFV18N60PS is determined by electrical and mechanical compatibility within the following critical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss): Must equal or exceed 600V
• Continuous Drain Current (Id): Must equal or exceed 18A at 25°C
• On-State Resistance (Rds On): Must not exceed 400mOhm at specified gate voltage
• Gate Threshold Voltage (Vgs th): Must be compatible with 10V drive voltage
• Operating Temperature Range: Must support -55°C to 150°C
• Maximum Gate Voltage (Vgs Max): Must support ±30V

Mechanical Compatibility Criteria:

• Mounting Type: Surface mount or through-hole packages acceptable for circuit redesign
• Package Classification: PLUS-220SMD is surface mount; through-hole alternatives require PCB layout modification

The APT18F60B from Microchip Technology meets the electrical requirements for substitution. This part maintains equivalent voltage and current ratings while offering improved on-state resistance characteristics and active product status.

Engineering Selection Recommendations

APT18F60B Substitution Assessment:

The APT18F60B is electrically qualified as a substitute for the IXFV18N60PS based on the following factors:

1. Voltage Rating: Both devices are rated for 600V Vdss, providing equivalent voltage withstand capability.

2. Current Rating: The APT18F60B provides 19A continuous drain current, exceeding the 18A requirement of the IXFV18N60PS.

3. On-State Resistance: The APT18F60B exhibits 390mOhm Rds On, which is lower than the 400mOhm specification of the IXFV18N60PS, resulting in improved efficiency.

4. Gate Drive Compatibility: Both devices operate with 10V gate drive voltage and support ±30V maximum gate voltage, ensuring compatibility with existing gate driver circuits.

5. Temperature Range: Both devices support the identical -55°C to 150°C operating temperature range.

6. Product Status: The APT18F60B is classified as active, ensuring long-term availability and supply chain continuity.

7. Compliance: The APT18F60B is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Package Consideration: The APT18F60B uses TO-247-3 through-hole packaging, whereas the IXFV18N60PS uses PLUS-220SMD surface mount packaging. PCB layout modification is required for mechanical integration.

Frequently Asked Questions (FAQ)

Q: Can the APT18F60B directly replace the IXFV18N60PS without circuit modification?

A: Electrical substitution is valid. The APT18F60B meets or exceeds all critical electrical parameters. However, the package change from PLUS-220SMD (surface mount) to TO-247-3 (through-hole) requires PCB layout modification. Gate drive and power supply connections remain compatible.

Q: What is the significance of the higher gate charge (Qg) in the APT18F60B?

A: The APT18F60B has a gate charge of 90nC compared to 50nC in the IXFV18N60PS. This parameter affects gate driver current requirements and switching speed. Gate drivers rated for the IXFV18N60PS must be verified for compatibility with the higher gate charge specification of the APT18F60B.

Q: Are there thermal considerations when substituting these parts?

A: The APT18F60B has a maximum power dissipation of 335W compared to 360W for the IXFV18N60PS. Both devices support the same operating temperature range (-55°C to 150°C). Thermal management design should account for the slightly lower power dissipation rating of the substitute part.

Q: Why is the IXFV18N60PS classified as obsolete?

A: The IXFV18N60PS is no longer in active production. Locating new inventory becomes increasingly difficult over time. The APT18F60B, classified as active, provides a path for continued design support and production continuity.

Q: What is the impact of higher input capacitance (Ciss) in the APT18F60B?

A: The APT18F60B has an input capacitance of 3550pF compared to 2500pF in the IXFV18N60PS. Higher input capacitance increases gate driver power dissipation and may affect switching frequency performance. Gate driver circuit analysis is required to confirm compatibility.

Q: Are moisture sensitivity levels equivalent between these parts?

A: Both the IXFV18N60PS and APT18F60B have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What compliance certifications apply to the APT18F60B?

A: The APT18F60B is RoHS3 compliant and REACH unaffected. Both devices share the same ECCN (EAR99) and HTSUS (8541.29.0095) classifications.
