FDMS86310 Equivalent & Substitute Parts

Part Overview

The FDMS86310 is an N-Channel MOSFET manufactured by onsemi, rated for 80V drain-to-source voltage with 17A continuous drain current (Ta) and 50A continuous drain current (Tc). This device is housed in an 8-PQFN (5x6) surface mount package and is part of the PowerTrench® series. The FDMS86310 is currently in active production status with 16,484 units in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be achieved within the specified parameter ranges. Alternative models may be required due to inventory constraints, application-specific thermal requirements, or design optimization needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FDMS86310 is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss) must equal or exceed 80V
• Gate Threshold Voltage (Vgs(th)) must be within ±20V maximum gate voltage specification
• Operating temperature range must support the application's thermal environment
• RDS(on) characteristics must be compatible with circuit current and power dissipation requirements

Mechanical Compatibility Criteria:

• Surface mount package type with compatible footprint dimensions (5x6mm nominal)
• Pin configuration compatible with 8-pin PQFN/PDFN/PDFN-variant packages
• Moisture sensitivity level MSL 1 or equivalent

Regulatory & Compliance Criteria:

• RoHS3 compliance required
• REACH unaffected status required
• EAR99 export classification

The STL130N8F7 meets these substitution criteria with equivalent Vdss (80V), compatible gate threshold voltage (4.5V @ 250µA), matching maximum gate voltage (±20V), and surface mount package compatibility. The STL130N8F7 provides enhanced current handling capability (130A Tc) and improved thermal performance (135W Tc) compared to the FDMS86310 (50A Tc, 96W Tc).

Engineering Selection Recommendations

FDMS86310 Selection: The FDMS86310 is appropriate for applications requiring 80V rated MOSFETs with moderate current handling (17A Ta, 50A Tc) in compact surface mount packages. This device maintains active production status with substantial inventory availability (16,484 units). The FDMS86310 satisfies RoHS3 compliance and MSL 1 moisture sensitivity requirements for standard industrial and consumer applications.

STL130N8F7 Selection: The STL130N8F7 is appropriate for applications requiring enhanced current capacity (130A Tc) and thermal performance (135W Tc) within the same 80V voltage class and compatible package footprint. This device is actively produced with 2,463 units in stock. The STL130N8F7 extends the maximum operating temperature to 175°C (compared to 150°C for FDMS86310) and maintains equivalent RoHS3 and REACH compliance status. The STL130N8F7 is suitable for high-current switching applications where thermal headroom and current density are critical design factors.

Both devices are compliant with RoHS3 and REACH regulations, carry EAR99 export classification, and maintain MSL 1 moisture sensitivity levels.

Frequently Asked Questions (FAQ)

Q: Can the STL130N8F7 directly replace the FDMS86310 in existing designs?

A: The STL130N8F7 is electrically and mechanically compatible with the FDMS86310 for applications operating within the FDMS86310's specified current and thermal limits. Both devices share identical Vdss (80V), Vgs(th) (4.5V @ 250µA), and maximum gate voltage (±20V) specifications. The 5x6mm package footprint is compatible between the 8-PQFN and PowerFlat™ variants. Pin configuration compatibility must be verified against the specific application schematic.

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

A: The primary differences are continuous drain current capacity (FDMS86310: 50A Tc; STL130N8F7: 130A Tc), power dissipation rating (FDMS86310: 96W Tc; STL130N8F7: 135W Tc), maximum operating temperature (FDMS86310: 150°C; STL130N8F7: 175°C), and RDS(on) characteristics (FDMS86310: 4.8mOhm @ 17A; STL130N8F7: 3.6mOhm @ 13A). Both devices maintain equivalent gate charge (95-96 nC @ 10V) and input capacitance (6290-6340 pF @ 40V).

Q: Are there packaging considerations when substituting these parts?

A: Both devices use 5x6mm surface mount packages (8-PQFN and PowerFlat™ variants). The physical footprint dimensions are compatible. However, the specific pin assignment and internal die layout may differ between manufacturers. PCB layout verification is necessary to confirm pin-to-pin compatibility with the application circuit.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the FDMS86310 and STL130N8F7 are RoHS3 compliant, REACH unaffected, carry EAR99 export classification, and maintain MSL 1 (unlimited) moisture sensitivity levels. Both devices are suitable for applications requiring equivalent regulatory compliance.

Q: Which device should be selected for high-temperature applications?

A: The STL130N8F7 supports operating temperatures up to 175°C (junction temperature), compared to 150°C for the FDMS86310. Applications requiring operation above 150°C must use the STL130N8F7 or identify alternative devices with higher temperature ratings.

Q: What is the significance of the different continuous drain current ratings?

A: The FDMS86310 is rated for 17A (Ta) and 50A (Tc) continuous drain current, while the STL130N8F7 is rated for 130A (Tc). The STL130N8F7 is suitable for higher-current switching applications. Applications operating below 50A can use either device; applications exceeding 50A require the STL130N8F7 or alternative high-current devices.
