Infineon Technologies IPA60R520E6XKSA1

Overview

IPA60R520E6 from Infineon Technologies is a 600 V, 0.52 Ω R_DS(on) CoolMOS™ E6 superjunction N-channel power MOSFET in PG-TO220 FullPAK package, optimized for high-efficiency PFC and hard-switching SMPS stages. It delivers 23.4 nC total gate charge, 2.1 µJ output energy at 400 V, and supports 22 A pulsed drain current - enabling compact, cooler-running server power supplies and telecom rectifiers.

For engineers reviewing the IPA60R520E6 datasheet, IPA60R520E6 pinout, IPA60R520E6 application, or IPA60R520E6 equivalent, key selection criteria include its 4.3 °C/W junction-to-case thermal resistance, 500 A/µs body diode commutation ruggedness, low 2.5–3.5 V gate threshold, and JEDEC-qualified Pb-free halogen-free construction for industrial-grade reliability.

Technical Context

This CoolMOS™ E6 device implements a superjunction (SJ) cell structure to achieve ultra-low figure-of-merit (R_DS(on) × Q_g = 12.2 Ω·nC typ), enabling high-frequency operation without sacrificing conduction loss. Its 50 V/ns MOSFET dv/dt ruggedness and 15 V/ns reverse diode dv/dt rating support robust operation in asymmetric half-bridge and LLC resonant topologies.

The integrated body diode exhibits 260 ns reverse recovery time and 2.5 µC Q_rr at 400 V, with controlled 500 A/µs di/dt capability - critical for minimizing voltage overshoot during ZVS transitions in PFC boost stages and telecom offline converters.

FAQ

What is the maximum recommended gate resistor value for IPA60R520E6 in a 200 kHz PFC application?

A 6.8 Ω gate resistor is validated in Infineon's reference design (Table 20, Rev. 2.2) for 400 V bus, 3.5 A current, and 200 kHz operation - balancing switching loss reduction against EMI control and gate oscillation suppression. Higher values increase turn-off time and may raise E_oss-related loss; lower values risk ringing and overshoot.

Can IPA60R520E6 be paralleled with identical units without external gate ferrites?

No - Infineon explicitly recommends using ferrite beads on each gate or separate totem-pole drivers when paralleling IPA60R520E6 units. This mitigates gate loop imbalance and prevents current hogging due to parameter spread and layout asymmetry, especially under hard-switching conditions above 100 kHz.

Is the drain tab of IPA60R520E6 electrically isolated from the package body?

Yes - the PG-TO220 FullPAK package features an isolated drain tab: the metal tab is internally connected only to the drain terminal (Pin 2), with reinforced creepage/clearance between tab and leads. This enables direct heatsink mounting without insulating pads in single-ended topologies.

What is the safe operating area (SOA) limitation at T_c = 100°C?

At T_c = 100°C, the continuous drain current is derated to 5.1 A (Table 2), and the SOA is constrained by R_DS(on) = 1.22 Ω at 150°C junction temperature. Pulse operation remains valid up to 22 A provided pulse width and duty cycle limit junction temperature rise below 150°C per thermal transient curves (Figure 10).
