Infineon Technologies IPA60R520C6XKSA1

Overview

IPA60R520C6XKSA1 from Infineon Technologies is a 600 V, 11 A (T_C = 100 °C) superjunction MOSFET in TO-220FP package, featuring R_DS(on) = 520 mΩ (max), optimized for hard-switching and resonant SMPS topologies in server power supplies, LED drivers, and industrial AC-DC converters.

For engineers reviewing the IPA60R520C6XKSA1 datasheet, IPA60R520C6XKSA1 pinout, IPA60R520C6XKSA1 application, or IPA60R520C6XKSA1 equivalent, key selection criteria include its low gate charge (Q_G = 27 nC), fast switching (t_on = 18 ns, t_off = 74 ns), and robust avalanche rating (E_AS = 290 mJ) - critical for high-efficiency, compact 600 V PFC and LLC stages.

Technical Context

This CoolMOS™ C6 device employs Infineon's superjunction technology with optimized charge balance, enabling lower R_DS(on) × Q_G figure-of-merit than prior generations. Its gate threshold voltage (V_GS(th) = 3.2–4.2 V) ensures stable turn-on under wide drive conditions, while low C_iss (1,100 pF) and C_oss (90 pF) support high-frequency operation up to 300 kHz.

The device integrates intrinsic fast-recovery body diode (t_rr = 120 ns, Q_rr = 1.9 µC) with soft recovery characteristics, reducing EMI and snubber losses in bridge configurations. Thermal resistance R_thJC = 1.2 K/W (TO-220FP) enables reliable conduction at T_J ≤ 150 °C under continuous 11 A drain current.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous drain current for IPA60R520C6XKSA1 at 100 °C case temperature?

The maximum continuous drain current I_D is 11 A when the case temperature T_C is maintained at 100 °C, as specified in the Absolute Maximum Ratings table of the Rev. 2.2 datasheet. This rating assumes proper heatsinking and excludes pulse conditions or transient overload scenarios.

Does IPA60R520C6XKSA1 require a negative gate turn-off voltage?

No - IPA60R520C6XKSA1 has a positive gate threshold voltage range of 3.2–4.2 V and is designed for standard 0 V/10–15 V gate drive. Negative turn-off voltage is not required or recommended; maintaining gate-source voltage ≥ –20 V avoids latch-up or parasitic thyristor activation.

Can IPA60R520C6XKSA1 be paralleled with identical units for higher current capacity?

Yes - the device exhibits positive temperature coefficient for R_DS(on), enabling stable current sharing when paralleled. Designers must match gate drive loop inductance and use individual gate resistors (≥10 Ω) to prevent oscillation; layout symmetry is critical for thermal and dynamic balance.

Is the TO-220FP package of IPA60R520C6XKSA1 electrically insulated?

Yes - the TO-220FP package features an insulated metal tab (drain-connected) with 2.5 kV AC isolation rating between drain and mounting surface. This eliminates need for insulating pads or shoulder washers in Class I safety-compliant designs, provided minimum creepage distances are maintained per IEC 62368-1.
