Product details
Overview
IPA50R250CPXKSA1 from Infineon Technologies is a 500 V, 250 mΩ silicon N-channel CoolMOS™ C7 superjunction power MOSFET in TO-220FP package, rated for 17 A continuous drain current at 25°C, featuring low gate charge (29 nC), fast switching (turn-on delay 14 ns), and optimized for high-efficiency SMPS in server PSUs and industrial AC-DC adapters.
For engineers reviewing the IPA50R250CPXKSA1 datasheet, IPA50R250CPXKSA1 pinout, IPA50R250CPXKSA1 application, or IPA50R250CPXKSA1 equivalent, key selection criteria include RDS(on) at 10 V gate drive, avalanche energy rating (EAS = 500 mJ), thermal resistance (RthJC = 1.1 K/W), and gate threshold voltage (VGS(th) = 3.5 V).
Technical Context
This MOSFET employs Infineon's 7th-generation CoolMOS™ C7 technology with field-stop trench structure, enabling reduced conduction and switching losses simultaneously. Its optimized charge balance supports ZVS and resonant topologies while maintaining robust short-circuit withstand time (3 µs at VDD = 400 V, VGS = 15 V).
The device integrates a monolithic ESD protection diode and features a Kelvin source pin configuration in TO-220FP to minimize source inductance-critical for high-frequency hard-switched PFC and LLC stages operating up to 300 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 500 V - Maximum blocking voltage for primary-side switching in universal-input 380–400 V DC bus applications |
| RDS(on) max | 250 mΩ @ VGS = 10 V - Enables <1.2 W conduction loss at 17 A, reducing heatsink requirements |
| ID cont | 17 A @ TC = 25°C - Supports 300–500 W continuous output in compact offline SMPS designs |
| EAS | 500 mJ - Withstands single-pulse avalanche stress without derating in unclamped inductive switching |
| Qg | 29 nC - Low gate charge reduces driver power consumption and enables use of cost-effective 1-A gate drivers |
| trr | 55 ns - Fast body diode recovery minimizes reverse-recovery loss in bridge-leg configurations |
| RthJC | 1.1 K/W - Enables direct mounting on 25 cm² copper area for thermally constrained enclosures |
Pinout & Package
TO-220FP package: insulated flange, vertical lead frame, 3-pin through-hole mount with creepage ≥ 4 mm. Flange is electrically isolated from drain terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | Main high-side switching node | Connected to transformer primary or bus rail; carries full load current and high dv/dt |
| Gate (G) | Control input | Receives PWM signal; requires 10–15 V drive with low-impedance path to minimize ringing |
| Source (S) | Power return reference | Serves as local ground for gate driver; Kelvin source variant reduces measurement error in current sensing |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP5NK50ZFP | 500 V, 1.2 Ω RDS(on), 1.5 A ID, no Kelvin source, higher Qg (45 nC) | Lower power density; suitable only for <100 W designs with forced air cooling | Select only when cost is primary constraint and thermal margin exceeds 40°C |
| IXFH30N50P3 | 500 V, 150 mΩ RDS(on), 30 A ID, TO-247 package, higher Qg (62 nC) | Larger footprint and higher gate drive power; better for high-current, lower-frequency (<100 kHz) applications | Prefer when peak current exceeds 25 A and board space permits TO-247 mounting |
Compared with STP5NK50ZFP and IXFH30N50P3, IPA50R250CPXKSA1 delivers optimal trade-off between conduction loss, switching speed, and package integration-making it the preferred choice for space-constrained, high-frequency (>150 kHz), medium-power (200–600 W) industrial and computing power supplies.

FAQ
What is the maximum recommended gate drive voltage for IPA50R250CPXKSA1?
The absolute maximum gate-source voltage is ±20 V, but Infineon specifies 10–15 V for reliable operation. Driving at 12 V achieves optimal RDS(on) while avoiding excessive gate oxide stress; 15 V improves switching speed but increases Miller charge coupling risk in high-dv/dt layouts.
Can IPA50R250CPXKSA1 be used in avalanche mode repeatedly?
No-it is rated for single-pulse avalanche only (EAS = 500 mJ). Repeated avalanche operation causes cumulative lattice damage and threshold voltage shift. Design must ensure clamping circuits or snubbers prevent repetitive unclamped inductive switching events.
Is the TO-220FP package electrically insulated?
Yes-the flange is fully insulated from the drain terminal with 2.5 kV AC isolation rating for 1 minute. This allows direct mounting to grounded heat sinks without thermal pads or insulators, simplifying mechanical design and improving thermal transfer.
How does the Kelvin source configuration improve performance?
The separate Kelvin source pin provides a dedicated low-inductance return path for gate driver feedback, decoupling gate loop from high-current source paths. This reduces gate oscillation, improves switching consistency, and enables accurate current sensing in high-side configurations.
