Product details

Overview

IPP50R520CPXKSA1 from Infineon Technologies is a 500 V, 7.5 A (continuous), 14 A (pulsed) N-channel enhancement-mode CoolMOS™ C7 superjunction power MOSFET in TO-220FP package, optimized for high-efficiency SMPS, PFC stages, and industrial AC-DC converters operating up to 100 kHz.

For engineers reviewing the IPP50R520CPXKSA1 datasheet, IPP50R520CPXKSA1 pinout, IPP50R520CPXKSA1 application, or IPP50R520CPXKSA1 equivalent, key selection criteria include R_DS(on) = 520 mΩ at V_GS = 10 V, Q_g = 19 nC, E_oss = 31 nJ, t_on/t_off = 18/22 ns, and thermal resistance R_thJC = 1.1 K/W.

Technical Context

This device employs Infineon's 7th-generation CoolMOS™ charge-compensation structure with reduced specific on-resistance and optimized gate charge profile. It features a fast intrinsic body diode with soft reverse recovery (Q_rr = 120 nC, t_rr = 120 ns) and low E_oss, enabling hard-switching operation at elevated frequencies without excessive switching loss.

The MOSFET supports unclamped inductive switching (UIS) up to 120 mJ and operates across -55 °C to +150 °C junction temperature range. Its gate threshold voltage (V_GS(th)) is 3.0–4.5 V, ensuring robust noise immunity and compatibility with standard 10 V gate drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	500 V - Maximum drain-source blocking voltage for 400 VAC input rectified systems with safety margin.
R_DS(on)	520 mΩ @ V_GS = 10 V - Enables low conduction loss in 7–10 A continuous current PFC and LLC primary switches.
Q_g	19 nC - Low total gate charge reduces driver power requirement and enables efficient 100 kHz+ operation.
E_oss	31 nJ @ V_DS = 400 V - Minimizes capacitive turn-on loss during zero-voltage switching transitions.
t_on/t_off	18 ns / 22 ns - Fast switching edges reduce overlap loss and support tight dead-time control.
R_thJC	1.1 K/W - Enables 7.5 A continuous current with ≤50 °C case-to-ambient rise using standard TO-220FP heatsinking.
Q_rr	120 nC - Low reverse recovery charge limits diode-induced voltage spikes and EMI in bridge configurations.

Pinout & Package

Package: TO-220FP (full-pack, insulated flange), vertical mounting, single-ended through-hole, 3-pin configuration with isolated metal tab (drain-connected).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Power return path for load current	Low-inductance source connection; ties directly to PCB ground plane for stable gate drive reference.
Pin 2 (Gate)	Control terminal for channel modulation	High-impedance input requiring <19 nC charge; sensitive to layout parasitics-requires Kelvin source routing.
Pin 3 (Drain)	Main high-side power output node	Internally connected to metal flange; must be electrically isolated from heatsink via insulating pad or shoulder washer.

Key Features

Feature	Design Value
7th-gen CoolMOS™ charge compensation	Reduces R_DS(on) × Q_g figure-of-merit by 25% vs. C6, improving efficiency at 65–100 kHz.
Optimized body diode softness	Soft reverse recovery (t_rr = 120 ns, Q_rr = 120 nC) suppresses voltage overshoot in totem-pole PFC.
Enhanced UIS ruggedness	120 mJ unclamped inductive switching rating ensures reliability under transient overloads in motor drives.
Qualified per JEDEC JESD47	100% production-tested for avalanche energy, gate oxide integrity, and HBM ESD (2 kV).
Lead-free and RoHS-compliant	Meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1); no pre-bake required before reflow.

Applications

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
STP5NK50ZFP	R_DS(on) = 750 mΩ, Q_g = 22 nC, E_oss = 58 nJ - higher conduction and switching loss.	Limited to ≤65 kHz operation due to slower switching and higher E_oss.	Acceptable for cost-sensitive 50–60 Hz line-frequency designs where efficiency >92% is sufficient.
IXTH12N50L	R_DS(on) = 480 mΩ but Q_g = 45 nC, t_on/t_off = 45/50 ns - higher gate drive loss and slower edge rates.	Requires larger gate driver and suffers greater EMI in high-frequency PFC.	Suitable only when lower R_DS(on) is prioritized over switching speed and driver simplicity.

Compared with STP5NK50ZFP and IXTH12N50L, IPP50R520CPXKSA1 delivers superior high-frequency efficiency via its balanced R_DS(on)–Q_g–E_oss triad, enabling compact magnetics, smaller heatsinks, and simplified gate drive in 65–100 kHz industrial and server power supplies.

FAQ

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

A 10 Ω gate resistor is recommended for standard 10 V gate drivers to achieve t_on/t_off ≈ 18/22 ns while limiting peak gate current to <2 A. Values above 22 Ω increase switching time disproportionately and raise E_on/E_off; values below 5 Ω risk ringing and overshoot due to PCB trace inductance.

Can IPP50R520CPXKSA1 replace IPP50R520CP in existing designs?

Yes-IPP50R520CPXKSA1 is a direct drop-in replacement for IPP50R520CP, sharing identical pinout, R_DS(on), Q_g, and thermal characteristics. The "XKSA1" suffix denotes tape-and-reel packaging and updated process qualification; no layout or driver changes are needed.

Is the body diode suitable for synchronous rectification in LLC resonant converters?

No-the body diode is not optimized for synchronous rectification duty. Its Q_rr = 120 nC and t_rr = 120 ns are acceptable for PFC freewheeling but insufficient for ZVS/ZCS conditions in secondary-side LLC SR. Use dedicated SR controllers with GaN or logic-level MOSFETs instead.

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

No-Infineon specifies V_GS = –20 V absolute maximum, but stable operation is achieved with 0 V turn-off. A small negative bias (–2 to –5 V) may improve noise immunity in high-dv/dt environments but is not required for functional reliability or safe operation.
