Key Parameters

Substitute Part Grouping Explanation

Substitution of the APT8014JLL is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• FET Type: N-Channel MOSFET technology
• Drain to Source Voltage (Vdss): 800V minimum rating
• Continuous Drain Current (Id): 42A or greater at 25°C
• On-State Resistance (Rds On): 140mOhm or lower at specified conditions
• Power Dissipation: 595W or greater
• Operating Temperature Range: -55°C to 150°C minimum
• Package: SOT-227-4 miniBLOC chassis mount configuration

Substitute Parts Identified:

The following IXYS HiPerFET™ series components meet the substitution criteria for the APT8014JLL:

1. IXFN60N80P – Exact voltage class match (800V), exceeds current rating (53A vs 42A), superior power dissipation (1040W vs 595W)
2. IXFN62N80Q3 – Exact voltage class match (800V), exceeds current rating (49A vs 42A), superior power dissipation (960W vs 595W)

The following IXYS HiPerFET™ series components provide partial substitution for lower voltage applications:

3. IXFN44N60 – Reduced voltage rating (600V vs 800V), exceeds current rating (44A vs 42A), comparable power dissipation (600W vs 595W)
4. IXFN48N60P – Reduced voltage rating (600V vs 800V), meets current requirement (40A vs 42A), superior power dissipation (625W vs 595W)

Parameter Comparison

Engineering Selection Recommendations

For Direct 800V Voltage Class Replacement:

IXFN60N80P and IXFN62N80Q3 are the primary substitutes for the APT8014JLL. Both devices maintain the 800V Vdss rating, exceed the 42A continuous drain current requirement, and provide superior power dissipation capabilities. Both substitute parts are classified as Active products with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory compliance.

IXFN60N80P provides the highest current rating (53A) and power dissipation (1040W), offering maximum design margin. IXFN62N80Q3 provides a balanced alternative with 49A current rating and 960W power dissipation while maintaining Q3 Class qualification.

For Reduced Voltage Applications (600V Systems):

IXFN44N60 and IXFN48N60P are suitable substitutes for applications where the 800V voltage rating is not required. IXFN44N60 exceeds the current requirement (44A vs 42A) with comparable power dissipation (600W). IXFN48N60P meets the current requirement (40A) with superior power dissipation (625W). Both devices are Active products with full regulatory compliance.

All substitute parts share identical package geometry (SOT-227-4 miniBLOC), mounting configuration (Chassis Mount), and operating temperature range (-55°C to 150°C), ensuring mechanical and thermal compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can IXFN44N60 or IXFN48N60P be used as direct replacements for APT8014JLL in 800V applications?

A: No. IXFN44N60 and IXFN48N60P are rated for 600V maximum Vdss, which is insufficient for 800V system requirements. These devices are suitable only for applications where the system voltage does not exceed 600V.

Q: What is the primary advantage of IXFN60N80P over IXFN62N80Q3?

A: IXFN60N80P provides higher continuous drain current (53A vs 49A) and greater power dissipation capability (1040W vs 960W). Selection between these two devices depends on specific application current and thermal requirements.

Q: Are all substitute parts mechanically compatible with the APT8014JLL footprint?

A: Yes. All identified substitute parts use the SOT-227-4 miniBLOC package with chassis mount configuration, providing identical mechanical compatibility and thermal interface requirements.

Q: What is the significance of the Vgs (Max) difference between APT8014JLL (±30V) and IXFN44N60 (±20V)?

A: The APT8014JLL and most IXYS substitutes accept ±30V gate-source voltage. IXFN44N60 is limited to ±20V. Gate drive circuits must be designed to operate within the specified Vgs limits of the selected device. For applications using ±30V gate drive, IXFN44N60 is not suitable.

Q: Are all substitute parts RoHS compliant?

A: Yes. All IXYS substitute parts (IXFN44N60, IXFN48N60P, IXFN60N80P, IXFN62N80Q3) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the difference between IXFN60N80P and IXFN62N80Q3 series designations?

A: IXFN60N80P is designated as HiPerFET™ Polar series, while IXFN62N80Q3 is designated as HiPerFET™ Q3 Class. Both are functionally equivalent for substitution purposes. The series designation reflects internal manufacturing and qualification classifications but does not affect electrical performance or compatibility.

Q: Can the APT8014JLL be used in new designs, or must substitutes be selected?

A: The APT8014JLL is classified as obsolete and should not be selected for new designs. Active substitute parts (IXFN60N80P or IXFN62N80Q3 for 800V applications) must be used to ensure long-term component availability and manufacturing support.
