Product details
Overview
IPA050N10NM5SXKSA1 from Infineon Technologies is a 100 V, 66 A N-channel enhancement-mode MOSFET in PG-TO220 FP package with drain-connected pin 2, gate on pin 1, and source on pin 3. It delivers 5.0 mΩ max RDS(on), 51 nC total gate charge, and 100% avalanche-tested ruggedness for high-frequency synchronous rectification and DC-DC power stages in server VRMs and telecom PSUs.
For engineers reviewing the IPA050N10NM5SXKSA1 datasheet, IPA050N10NM5SXKSA1 pinout, IPA050N10NM5SXKSA1 application, or IPA050N10NM5SXKSA1 equivalent, key selection criteria include its low Qg×RDS(on) figure-of-merit (255 mΩ·nC), 67 nC output charge, 4.5 V gate plateau voltage, and thermal resistance of 3.9 °C/W junction-to-case - critical for thermally constrained high-efficiency converters.
Technical Context
This OptiMOSTM 5 device uses trench-gate superjunction technology to achieve ultra-low on-resistance while maintaining fast switching performance. Its 3600 pF input capacitance and 25 pF reverse transfer capacitance enable stable gate drive at >1 MHz frequencies, and the 48 ns reverse recovery time supports efficient synchronous FET operation in buck converters.
The MOSFET features a robust 110 mJ single-pulse avalanche energy rating and operates across –55 °C to +175 °C junction temperature range. Its 0.95 V typical body diode forward voltage at 66 A and 25 °C reduces conduction loss during dead-time conduction in half-bridge topologies.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N10F7 | 6.0 mΩ RDS(on), 45 nC Qg, TO-220FP package, 100 V rating | Lower gate charge but higher on-resistance - better for very high-frequency (>1.2 MHz) but lower-current (<50 A) designs | Select when prioritizing switching loss over conduction loss in compact, air-cooled converters |
| IXFH50N10X | 5.5 mΩ RDS(on), 62 nC Qg, TO-247AC package, 100 V rating | Larger package with higher thermal mass - suited for higher ambient temperatures (>85 °C) and longer lifetime requirements | Select when board space permits larger footprint and long-term reliability outweighs efficiency optimization |
Compared with STL220N10F7 and IXFH50N10X, IPA050N10NM5SXKSA1 offers the lowest RDS(on) × Qg product (255 mΩ·nC), making it optimal for high-current, medium-frequency (500 kHz–1 MHz) applications where conduction loss dominates total power loss.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
The IPA050N10NM5SXKSA1 supports 47 A continuous drain current at TC = 100 °C, as specified in Table 2 of the datasheet. This derating reflects thermal limitations of the PG-TO220 FP package and must be applied when heatsink temperature exceeds 25 °C ambient conditions.
Is this MOSFET suitable for synchronous rectification in LLC resonant converters?
Yes - its 48 ns reverse recovery time, 62 nC Qrr, and low 5.0 mΩ RDS(on) make it well-suited for secondary-side synchronous rectification in LLC converters operating up to 500 kHz. The 4.5 V gate plateau voltage ensures clean turn-on even with moderate gate drive impedance.
Does the device require a negative gate voltage for reliable turn-off?
No - the IPA050N10NM5SXKSA1 has a gate threshold voltage range of 2.2–3.8 V and is fully enhanced at 0 V gate-source bias. A negative gate voltage is not required; however, applying –5 V can improve noise immunity in high-dV/dt environments like motor drives.
How does the FullPAK package differ from standard TO-220 in thermal performance?
The PG-TO220 FP (FullPAK) package integrates an isolated drain tab directly bonded to the die's drain metallization, reducing thermal resistance to 3.9 °C/W (junction-to-case) - 15% lower than standard TO-220 variants. This enables higher power density without increasing heatsink size or airflow requirements.
