Infineon Technologies IPA50R380CEXKSA2

Overview

IPA50R380CEXKSA2 from Infineon Technologies is a 500 V, 0.38 Ω R_DS(on) CoolMOS™ CE superjunction power MOSFET in PG-TO220 FP package with drain-connected pin 2, gate on pin 1, and source on pin 3. It delivers 14.1 A continuous drain current at T_C = 25°C, 24.8 nC total gate charge, and 2.54 µJ output switching energy at 400 V - optimized for high-efficiency PFC and hard-switching SMPS in LCD TV and lighting adapters.

For engineers reviewing the IPA50R380CEXKSA2 datasheet, IPA50R380CEXKSA2 pinout, IPA50R380CEXKSA2 application, or IPA50R380CEXKSA2 equivalent, key selection criteria include its 550 V V_DS rating at T_j,max, 50 V/ns dv/dt ruggedness, 173 mJ single-pulse avalanche energy, and TO-220 FullPAK insulation rating of 2500 V_rms.

Technical Context

This CoolMOS™ CE device implements a superjunction structure enabling low R_DS(on) × Q_g figure-of-merit (0.38 Ω × 24.8 nC) and ultra-low E_oss (2.54 µJ @ 400 V), directly reducing conduction and switching losses in 65–100 kHz PFC and PWM stages. Its 5.3 V gate plateau voltage and 3.1 nC Q_gs support stable, low-noise gate driving with standard 13 V logic-level controllers.

The integrated body diode exhibits 207 ns reverse recovery time and 1.7 µC Q_rr at 400 V, enabling robust commutation in continuous-conduction-mode boost PFC. Thermal resistance R_thJC is 4.28 °C/W, allowing 29.2 W power dissipation at T_C = 25°C without forced cooling.

FAQ

Is IPA50R380CEXKSA2 pin-compatible with standard TO-220 MOSFETs?

Yes - it uses the PG-TO220 FullPAK footprint with identical mechanical dimensions and mounting hole pattern as standard TO-220 devices. Pin 1 (gate), pin 2 (drain), and pin 3 (source) follow JEDEC TO-220AB pinout, but the drain is internally connected to the metal tab, providing both thermal and electrical connection.

What is the maximum recommended gate resistor value for reliable switching?

A 3.4 Ω external gate resistor is validated in the datasheet for 400 V, 3.9 A switching tests, yielding 5.6 ns rise time and 8.6 ns fall time. For 14.1 A operation, values between 2.2 Ω and 4.7 Ω maintain safe dv/dt control while limiting gate driver peak current to ≤1.5 A.

Does IPA50R380CEXKSA2 require a gate ferrite bead when paralleled?

Yes - the datasheet explicitly recommends using ferrite beads on each gate line or separate totem-pole drivers when paralleling multiple units. This prevents oscillation and unequal current sharing caused by gate loop inductance mismatch during high-di/dt switching.

Can IPA50R380CEXKSA2 replace older CoolMOS™ C3 or C7 devices in existing designs?

Yes - it is a direct drop-in replacement for IPA50R380CP (C3) and IPA50R380C7 (C7) in the same TO-220 FP package. Electrical improvements include 12% lower R_DS(on) and 18% lower E_oss, enabling immediate efficiency gains without layout changes.
