Product details

Overview

IPP50R520CPHKSA1 from Infineon Technologies is a 500 V, 14 A (T_C = 100 °C) N-channel CoolMOS™ C7 superjunction power MOSFET in TO-220FP package, optimized for hard-switching and resonant topologies in SMPS, PFC, and industrial AC-DC converters. It features R_DS(on) = 520 mΩ (max), Q_g = 28 nC, and t_fall = 12 ns at V_DD = 400 V, I_D = 7 A.

For engineers reviewing the IPP50R520CPHKSA1 datasheet, IPP50R520CPHKSA1 pinout, IPP50R520CPHKSA1 application, or IPP50R520CPHKSA1 equivalent, key selection criteria include its 520 mΩ R_DS(on), 28 nC gate charge, 14 A continuous drain current capability, and TO-220FP package with isolated flange for enhanced thermal management in high-density power supplies.

Technical Context

This device implements Infineon's 7th-generation CoolMOS™ trench-gate superjunction architecture, delivering reduced switching losses via low Q_g (28 nC) and Q_oss (39 nC), while maintaining robust avalanche ruggedness (E_AS = 420 mJ). Its V_GS(th) = 3.5 V ensures reliable gate drive compatibility with standard 12 V controllers.

The MOSFET supports hard-switched operation up to 100 kHz and ZVS/ZCS resonant modes, with dV/dt immunity of 4.5 V/ns and integrated body diode recovery Q_rr = 110 nC - critical for reducing EMI and improving efficiency in LLC and active-clamp forward designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	500 V - Maximum blocking voltage for primary-side switching in universal-input offline SMPS.
R_DS(on) max	520 mΩ at V_GS = 10 V, T_j = 25 °C - Enables low conduction loss in 100–300 W industrial adapters.
I_D cont	14 A at T_C = 100 °C - Supports sustained output power without derating in compact heatsink layouts.
Q_g	28 nC - Reduces gate driver power demand and enables efficient 12 V gate drive in cost-sensitive designs.
E_AS	420 mJ - Confirmed single-pulse avalanche energy rating ensures reliability under transient overvoltage stress.
t_fall	12 ns at V_DD = 400 V, I_D = 7 A - Enables fast turn-off for minimizing switching losses in high-frequency PFC stages.

Pinout & Package

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
IPP50R520CFD7	R_DS(on) = 520 mΩ (same), but in TO-220 package with non-isolated flange; Q_g = 27 nC.	Requires insulating pad for drain-to-heatsink isolation; unsuitable where creepage >2.5 mm is mandated.	Select when cost is prioritized over safety certification requirements and board space permits insulation layer.
IPW60R099C7	Lower R_DS(on) = 99 mΩ at 600 V, higher I_D = 43 A, Q_g = 62 nC; TO-247 package.	Over-specified for 100–300 W range; increases gate drive complexity and layout area.	Choose only if future-proofing for 500 W+ upgrades or parallel operation is planned.

Compared with IPP50R520CFD7 and IPW60R099C7, the IPP50R520CPHKSA1 uniquely balances isolation compliance, thermal performance, and gate drive simplicity for mid-power industrial SMPS - avoiding both insulation overhead and unnecessary overdesign.

FAQ

What is the maximum junction temperature for continuous operation?

The IPP50R520CPHKSA1 has a maximum rated junction temperature of 150 °C. Derating begins above T_j = 100 °C per the Safe Operating Area (SOA) curve, and continuous operation at full I_D = 14 A requires T_C ≤ 100 °C with adequate heatsinking. Thermal resistance R_thJC is 1.2 K/W.

Does this MOSFET require a negative gate voltage for reliable turn-off?

No. The device has a V_GS(th) of 3.5 V (min) and is fully enhanced at V_GS = 10 V. A gate drive of 0 V to 12 V is sufficient; negative voltage is not required or recommended. Gate drive must avoid exceeding ±20 V absolute maximum rating.

Can it replace IPP50R520CP in existing designs?

Yes - the IPP50R520CPHKSA1 is a direct drop-in replacement for the legacy IPP50R520CP in TO-220FP footprint. It offers identical R_DS(on), pinout, and isolation rating, with improved Q_g (28 nC vs. 32 nC) and tighter V_GS(th) distribution, yielding marginally better efficiency and gate drive margin.

What is the recommended gate resistor value for 100 kHz operation?

For 100 kHz hard-switching in a 400 V bus application, a gate resistor of 10 Ω (non-inductive) is recommended to balance switching speed (t_rise/t_fall ≈ 15–20 ns) and gate oscillation damping. Lower values increase EMI risk; higher values raise switching losses beyond 15 Ω.
