Product details
Overview
IPA040N08NM5SXKSA1 from Infineon Technologies is an N-channel enhancement-mode MOSFET in PG-TO220FP package, rated for 80 V VDS, 4.0 mΩ RDS(on) max at VGS = 10 V, and 75 A continuous drain current at TC = 25 °C. It features 100% avalanche tested ruggedness, low Qg (70 nC), and optimized FOM for high-frequency synchronous rectification in DC-DC converters.
For engineers reviewing the IPA040N08NM5SXKSA1 datasheet, IPA040N08NM5SXKSA1 pinout, IPA040N08NM5SXKSA1 application, or IPA040N08NM5SXKSA1 equivalent, key selection criteria include its 3.8 °C/W thermal resistance (RthJC), 83 nC output charge (Qoss), gate plateau voltage of 4.5 V, and suitability for high-efficiency 48 V input server power supplies and motor drive half-bridges.
Technical Context
This OptiMOSTM 5 device employs a trench-gate superjunction structure enabling ultra-low RDS(on) while maintaining fast switching with 18 ns turn-on delay and 12 ns rise time under 40 V VDD, 38 A ID conditions. Its gate threshold voltage (2.2–3.8 V) ensures robust noise immunity and compatibility with standard 5 V or 3.3 V logic-level drivers.
The integrated body diode delivers 33 A continuous forward current and exhibits 73 ns reverse recovery time with 166 nC Qrr, supporting efficient synchronous rectification without external Schottky diodes. Thermal design is enabled by its 3.8 °C/W junction-to-case resistance and 175 °C maximum junction temperature rating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 80 V power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N8F7AG | RDS(on) = 2.2 mΩ (lower), but Qg = 105 nC (higher); DFN8 5×6 mm package, no isolated tab | Requires PCB copper area for thermal management; unsuitable for TO-220FP socket replacement | Select when board space is constrained and thermal interface uses soldered copper, not mechanical heatsink. |
| IRF1407PBF | RDS(on) = 7.5 mΩ (higher), Qg = 110 nC (higher); TO-220AB package, non-isolated drain | Lacks avalanche rating and halogen-free compliance; older generation with higher conduction loss | Acceptable only for cost-sensitive, non-avalance-critical 100 kHz designs where efficiency >94 % is not required. |
Compared with STL220N8F7AG and IRF1407PBF, IPA040N08NM5SXKSA1 uniquely balances low RDS(on), moderate Qg, TO-220FP isolation, and qualified avalanche performance-making it optimal for thermally demanding, high-reliability 48 V industrial and telecom power stages.

FAQ
What is the maximum recommended gate-source voltage for IPA040N08NM5SXKSA1?
The absolute maximum gate-source voltage is ±20 V per datasheet Table 2. Operation above 12 V provides no RDS(on) benefit beyond 10 V, and sustained bias above 15 V accelerates gate oxide degradation. Recommended drive is 10 V with <±5 V transient tolerance during switching transitions.
Can IPA040N08NM5SXKSA1 be used in parallel configurations?
Yes-its positive temperature coefficient of RDS(on) (see Diagram 9) ensures inherent current sharing. Parallel operation requires matched gate drive impedance (<1 Ω difference), symmetrical PCB layout, and individual gate resistors (≥5 Ω) to suppress oscillation. Derate total current by 15 % for thermal margin.
Is the drain tab electrically isolated in the PG-TO220FP package?
Yes-the PG-TO220FP package features an electrically isolated drain tab (Pin 2), allowing direct mechanical attachment to a heatsink without insulating hardware. The isolation withstands ≥2.5 kV AC for 1 minute per Infineon's package specification, enabling safe high-voltage thermal management.
Does IPA040N08NM5SXKSA1 require a negative gate turn-off voltage?
No-its gate threshold voltage (2.2–3.8 V) and low leakage (100 nA IGSS max) permit reliable turn-off with 0 V gate drive. Negative bias is unnecessary and may increase gate driver complexity without measurable improvement in dV/dt immunity or switching speed.
