Product details

Overview

IPS50R520CP from Infineon Technologies is a 550 V, 0.520 Ω R_DS(on) CoolMOS™ CP superjunction power MOSFET in PG-TO251 package, optimized for hard- and soft-switching SMPS in server power supplies and DCM PFC stages in lamp ballasts and LCD/PDP TVs. It delivers 7.1 A continuous drain current at T_C = 25 °C, 13 nC typical gate charge, and 166 mJ single-pulse avalanche energy.

For engineers reviewing the IPS50R520CP datasheet, IPS50R520CP pinout, IPS50R520CP application, or IPS50R520CP equivalent, key selection criteria include R_DS(on) × Q_g figure of merit, dv/dt ruggedness (400 V/ns), peak current capability (15 A pulsed), and thermal resistance (1.9 K/W junction-to-case).

Technical Context

This device employs Infineon's 4th-generation CoolMOS™ CP technology, featuring optimized charge distribution for ultra-low gate charge (Q_g = 13 nC typ) and reduced R_DS(on) × Q_g FoM. Its 550 V V_(BR)DSS rating supports 400 V DC-link operation with margin, and its 400 V/ns dv/dt rating enables robust operation in high-speed switching topologies without spurious turn-on.

The integrated body diode exhibits 240 ns reverse recovery time (t_rr) and 1.6 µC Q_rr at I_F = 3.8 A, enabling efficient operation in PFC and resonant converters. Thermal design is supported by low R_thJC = 1.9 K/W and validated JEDEC qualification for industrial and lighting applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_(BR)DSS	550 V - Withstands 400 V DC-link with 37.5% voltage margin for reliability in surge-prone server PSUs
R_DS(on),max	0.520 Ω @ T_j = 25 °C - Enables low conduction loss in 3.8 A continuous operation at 100 °C case temperature
Q_g,typ	13 nC - Reduces gate drive power and EMI in 100–300 kHz SMPS designs
E_AS	166 mJ - Supports single-pulse avalanche capability during transient overvoltage events in PFC circuits
dv/dt ruggedness	400 V/ns - Prevents false triggering in high-di/dt half-bridge and LLC resonant converter nodes
R_thJC	1.9 K/W - Allows 7.1 W dissipation at ΔT = 13.5 °C rise from case to junction, simplifying heatsink sizing
t_rr	240 ns - Limits reverse recovery losses in discontinuous conduction mode PFC stages

Pinout & Package

IPS50R520CP uses the PG-TO251 (IPAK) surface-mount package with isolated tab, rated for 60 Ncm mounting torque on M3/M3.5 screws. The package provides low thermal resistance (R_thJC = 1.9 K/W) and RoHS-compliant lead plating.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	High-side power switch node	Electrically connected to exposed metal tab; must be electrically isolated from heatsink unless referenced to same potential
Source	Power return / reference node	Low-inductance connection point for source routing and Kelvin sensing in high-frequency layouts
Gate	Control input	High-impedance terminal requiring <2.2 Ω series gate resistor to damp ringing and limit peak current

Key Features

Feature	Design Value
Ultra-low R_DS(on) × Q_g FoM	6.756 Ω·nC - Directly reduces total switching + conduction loss in 100–500 kHz SMPS
Extreme dv/dt rating	400 V/ns - Eliminates need for external gate clamping in hard-switched bridge legs
JEDEC-qualified reliability	Qualified per J-STD-20/JESD22 - Validated for reflow and mechanical stress in industrial lighting and server PSU production
Enhanced body diode performance	t_rr = 240 ns, Q_rr = 1.6 µC - Lowers reverse recovery loss and EMI in DCM PFC compared to standard SJ-MOSFETs

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage superjunction MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP60R520CP	Same die, TO-220 package; R_thJA = 62 K/W (leaded) vs. 1.9 K/W (j-c); no isolation on tab	Requires through-hole PCB layout and larger heatsink; unsuitable for space-constrained SMT designs	Select when board-level isolation is not required and manual assembly is acceptable
IPW60R099C6	650 V, 0.099 Ω R_DS(on), 42 nC Q_g; higher conduction efficiency but 3.2× higher switching loss	Better for <100 kHz fixed-frequency hard-switching; less suitable for >200 kHz soft-switching due to Q_g	Select only if lower R_DS(on) dominates system loss budget and frequency is ≤100 kHz

Compared with IPP60R520CP and IPW60R099C6, IPS50R520CP uniquely balances low Q_g and moderate R_DS(on) for optimal efficiency in 150–300 kHz server and lighting SMPS, while its PG-TO251 package enables compact, thermally efficient SMT implementation.

FAQ

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

The IPS50R520CP supports 4.5 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits imposed by R_thJC = 1.9 K/W and junction temperature cap of 150 °C, ensuring safe operation in enclosed server PSU environments.

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

No. The IPS50R520CP has a gate threshold voltage range of 2.5–3.5 V and is fully compatible with standard 0 V/10 V or 0 V/12 V gate drive schemes. Its gate-source voltage rating of ±20 V allows use of simple unipolar drivers without negative bias circuitry.

Can the body diode be used for synchronous rectification?

No - the body diode is not optimized for synchronous rectification. With t_rr = 240 ns and Q_rr = 1.6 µC, it introduces significant reverse recovery loss and EMI. Dedicated SR controllers with external low-V_F Schottky or GaN FETs are recommended for that function.

Is the PG-TO251 package lead-free and RoHS compliant?

Yes. The IPS50R520CP features Pb-free lead plating and is fully RoHS compliant per EU Directive 2011/65/EU. Its soldering profile is qualified for wave soldering at 260 °C for 10 s at 1.6 mm from case, and compatible with standard lead-free reflow profiles (J-STD-020).
