SPD11N10 N-Channel MOSFET 100V 10.5A Equivalent & Substitute Parts

Part Overview

The SPD11N10 is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 100V drain-to-source voltage with 10.5A continuous drain current at 25°C. The device is housed in a TO-252-3 (DPAK) surface mount package and is classified as obsolete. Due to its obsolete status, equivalent substitute parts are necessary for ongoing design support, production continuity, and component sourcing. Substitute parts must maintain electrical compatibility across voltage ratings, current handling, and thermal characteristics while accommodating the same or compatible package footprints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPD11N10 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Drain-to-Source Voltage (Vdss): Must equal 100V
• FET Type: Must be N-Channel
• Technology: Must be MOSFET (Metal Oxide)
• Package / Case: Must be TO-252-3 (DPAK) or compatible surface mount equivalent
• Mounting Type: Must be Surface Mount

Secondary Compatibility Parameters:

• Continuous Drain Current (Id) @ 25°C: Substitute must meet or exceed 10.5A
• On-Resistance (Rds On): Lower values indicate improved performance; maximum acceptable is 190mOhm
• Gate Threshold Voltage (Vgs(th)): Must be within ±20V maximum gate voltage specification
• Operating Temperature Range: Must support -55°C to 175°C or equivalent industrial range
• Power Dissipation: Must support minimum 50W thermal capability

All identified substitute parts meet the primary criteria of 100V Vdss, N-Channel configuration, MOSFET technology, and TO-252-3 package compatibility. Substitutes vary in current rating, on-resistance, and power dissipation characteristics, allowing selection based on specific application requirements.

Engineering Selection Recommendations

For Direct Replacement (Closest Electrical Match):

STD10NF10T4 (STMicroelectronics) is the primary recommended substitute. It maintains 100V Vdss, delivers 13A continuous drain current (exceeding the 10.5A requirement), and provides superior on-resistance of 130mOhm compared to the SPD11N10's 170mOhm. The device is rated for -55°C to 175°C operating temperature, matching the original specification. STD10NF10T4 is active in production and ROHS3 compliant, ensuring long-term availability and regulatory compliance.

For Current-Limited Applications:

FQD13N10TM (onsemi) provides 10A continuous drain current with 180mOhm on-resistance and 40W power dissipation. This substitute is suitable for applications where the 10.5A rating of the original part is not fully utilized. The device is active in production and ROHS3 compliant.

For High-Current Applications:

BUK7275-100A,118 (Nexperia) delivers 21.7A continuous drain current with superior 75mOhm on-resistance and 89W power dissipation capability. This substitute is appropriate for designs requiring higher current handling or lower thermal resistance. The device qualifies to AEC-Q101 automotive standards. Note: BUK7275-100A,118 is classified as obsolete; verify long-term availability before selection.

For Lower-Current, Lower-Power Applications:

FDD1600N10ALZ (onsemi) and RSD050N10TL (Rohm) are suitable for applications where the full 10.5A rating is not required. FDD1600N10ALZ provides 6.8A at 14.9W power dissipation and is active in production. RSD050N10TL provides 5A at 15W power dissipation and is active in production. Both are ROHS3 compliant.

Compliance and Availability Considerations:

All active-status substitutes (STD10NF10T4, FQD13N10TM, FDD1600N10ALZ, RSD050N10TL) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Inventory availability is confirmed for all listed substitutes. For new designs, prioritize active-status parts to ensure long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can I use FDD1600N10ALZ as a direct replacement for SPD11N10?

A: FDD1600N10ALZ is electrically compatible in terms of voltage rating (100V Vdss) and package (TO-252-3 DPAK). However, it provides only 6.8A continuous drain current compared to the SPD11N10's 10.5A. Use FDD1600N10ALZ only if your application does not require the full 10.5A current rating. For applications requiring 10.5A or higher, select STD10NF10T4 or FQD13N10TM.

Q: What is the difference between Tc and Ta temperature ratings?

A: Tc denotes case temperature, while Ta denotes ambient temperature. Specifications using Tc typically indicate higher thermal performance under controlled cooling conditions. Both SPD11N10 and its substitutes use Tc ratings for current and power dissipation specifications, ensuring consistent comparison across parts.

Q: Is the TO-252-3 package footprint identical across all substitute parts?

A: Yes. All listed substitute parts use the TO-252-3 (DPAK) package with identical pin configuration and footprint. Direct PCB layout substitution is possible without redesign. Verify specific supplier device package designations (e.g., DPAK, TO-252AA, CPT3) with your PCB layout tool to confirm compatibility.

Q: Why does BUK7275-100A,118 have higher input capacitance (Ciss) than other substitutes?

A: BUK7275-100A,118 delivers significantly higher current (21.7A) and lower on-resistance (75mOhm), which typically correlates with larger die size and higher capacitance. Higher Ciss may increase gate drive requirements and switching losses in high-frequency applications. Evaluate gate drive circuit capability before selecting this part for frequency-sensitive designs.

Q: Can I use RSD050N10TL in a design originally specified for SPD11N10?

A: RSD050N10TL is electrically compatible for voltage (100V Vdss) and package (TO-252-3 DPAK). However, it provides only 5A continuous drain current. Use RSD050N10TL only if your application current requirement does not exceed 5A. For applications requiring 10.5A, this part is not suitable.

Q: What is the significance of "Obsolete" product status?

A: Obsolete status indicates the manufacturer has discontinued production. SPD11N10 and BUK7275-100A,118 are both obsolete. Active-status substitutes (STD10NF10T4, FQD13N10TM, FDD1600N10ALZ, RSD050N10TL) are currently manufactured and supported. For new designs and long-term production, select active-status parts to ensure supply chain continuity.

Q: Are all substitute parts ROHS3 compliant?

A: All active-status substitute parts (STD10NF10T4, FQD13N10TM, FDD1600N10ALZ, RSD050N10TL) are ROHS3 compliant. The original SPD11N10 and obsolete substitute BUK7275-100A,118 do not list explicit ROHS3 compliance. For applications requiring ROHS3 certification, use only active-status substitutes.

Q: How do I select between STD10NF10T4 and FQD13N10TM?

A: Both parts meet the 100V Vdss and 10+ A current requirements. STD10NF10T4 provides 13A with 130mOhm on-resistance and 50W power dissipation. FQD13N10TM provides 10A with 180mOhm on-resistance and 40W power dissipation. Select STD10NF10T4 for applications requiring lower on-resistance and higher power handling. Select FQD13N10TM for cost-optimized designs where 10A current is sufficient.
