Infineon Technologies IPA60R650CEXKSA1

Overview

IPA60R650CEXKSA1 from Infineon Technologies is a 600 V, 9.9 A CoolMOS™ CE superjunction power MOSFET in TO-220FP (FullPAK) package, featuring 650 mΩ max R_DS(on), 20.5 nC typical gate charge, and 1.9 µJ E_oss at 400 V. It serves as a high-efficiency primary-side switch in hard-switched and resonant SMPS topologies for consumer and lighting applications.

For engineers reviewing the IPA60R650CEXKSA1 datasheet, IPA60R650CEXKSA1 pinout, IPA60R650CEXKSA1 application, or IPA60R650CEXKSA1 equivalent, key selection criteria include its 4.5 °C/W R_thJC, 28 W P_tot at T_C=25°C, 50 V/ns dv/dt ruggedness, and suitability for PFC and LLC stages in compact AC/DC adapters and indoor LED drivers.

Technical Context

This device implements Infineon's CoolMOS™ CE superjunction architecture optimized for cost-sensitive, high-efficiency 600 V switching. Its low FOM (R_DS(on) × Q_g) enables reduced conduction and switching losses without compromising gate drive simplicity or commutation robustness.

The TO-220FP package integrates an isolated drain tab rated for 2500 V_rms insulation, supporting high-voltage isolation requirements in offline converters. Its 15 V/ns reverse diode dv/dt rating and 500 A/µs di/dt capability ensure reliable operation in fast-recovery synchronous rectification and resonant circuits.

FAQ

What is the maximum continuous drain current for IPA60R650CEXKSA1 at 100°C case temperature?

The maximum continuous drain current is 6.2 A at T_C = 100°C, as specified in Table 2 of the datasheet. This derating reflects thermal limits of the TO-220FP package and must be applied when heatsink temperature exceeds 25°C. Designers should verify junction temperature using R_thJC = 4.5 °C/W and actual power dissipation.

Does IPA60R650CEXKSA1 have an integrated body diode, and what are its recovery characteristics?

Yes, it includes a fast-recovery epitaxial body diode with t_rr = 250 ns, Q_rr = 2.1 µC, and I_RRM = 16 A at V_R = 400 V and dI_F/dt = 100 A/µs. These values enable use in quasi-resonant and LLC topologies where diode reverse recovery affects efficiency and EMI.

Can IPA60R650CEXKSA1 be paralleled with identical units, and what layout precautions apply?

Yes, parallel operation is supported but requires individual gate ferrite beads or separate totem-pole drivers per device to prevent oscillation and current imbalance. The datasheet explicitly recommends this in Note 1. Layout must ensure symmetrical source inductance and thermal coupling to avoid thermal runaway.

What is the insulation rating of the TO-220FP package, and how does it impact system-level safety design?

The TO-220FP package provides 2500 V_rms insulation withstand voltage between drain tab and other terminals for 1 minute at 25°C. This eliminates need for additional insulating hardware in Class II AC/DC designs and simplifies creepage/clearance compliance in compact adapters and LED drivers meeting IEC 62368-1.
