Product details

Overview

IPP50R350CPHKSA1 from Infineon Technologies is a 500 V, 0.35 Ω R_DS(on) CoolMOS™ CPl series superjunction N-channel power MOSFET in PG-TO220 package, featuring 19 nC typical gate charge, 5.6 A continuous drain current at T_C = 25 °C, and extreme dv/dt ruggedness up to 400 V/ns - optimized for hard- and soft-switching SMPS in industrial lamp ballasts and LCD/PDP TV power supplies.

For engineers reviewing the IPP50R350CPHKSA1 datasheet, IPP50R350CPHKSA1 pinout, IPP50R350CPHKSA1 application, or IPP50R350CPHKSA1 equivalent, key selection criteria include R_DS(on) × Q_g figure-of-merit, avalanche energy rating (246 mJ), diode reverse recovery performance (Q_rr = 2.3 µC), thermal resistance (R_thJC = 1.4 K/W), and JEDEC industrial-grade qualification.

Technical Context

This device implements Infineon's 4th-generation CoolMOS™ CP technology with optimized charge distribution for reduced conduction and switching losses. Its ultra-low gate charge (Q_g = 19 nC typ.) and low output capacitance (C_oss = 46 pF) enable high-frequency operation in PFC and PWM stages while maintaining robust avalanche capability (E_AS = 246 mJ).

The integrated body diode exhibits fast reverse recovery (t_rr = 250 ns) and low Q_rr, supporting ZVS/ZCS topologies. Gate threshold voltage (V_GS(th) = 2.5–3.5 V) ensures stable turn-on under wide V_GS margin, and dv/dt immunity (≥400 V/ns) prevents spurious turn-on in noisy high-voltage environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	500 V - supports 400 V DC-link applications with 25% safety margin for transient overvoltage
R_DS(on) max @ 25 °C	0.35 Ω - enables low conduction loss in 5.6 A continuous current SMPS designs
Q_g typ.	19 nC - reduces gate drive power and allows use of smaller, lower-cost drivers
E_AS	246 mJ - provides single-pulse avalanche robustness without external snubbers in PFC circuits
t_rr	250 ns - limits diode switching loss and EMI in bridge-leg configurations
R_thJC	1.4 K/W - enables efficient heat transfer to heatsink in TO-220 mounting
dv/dt ruggedness	≥400 V/ns - suppresses false triggering in high-slew-rate hard-switched converters

Pinout & Package

Package: PG-TO220 (3-pin, through-hole, isolated tab). Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source. Drain connected to metal tab for direct heatsinking; gate-source isolation rated per JEDEC industrial standards.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate terminal	Low-impedance control input; requires <20 V absolute max rating; sensitive to ESD
Pin 2 (D)	Drain terminal / heatsink interface	High-voltage power node; electrically connected to metal tab; must be insulated from chassis unless referenced to same potential
Pin 3 (S)	Source terminal	Return path for load current; reference for gate drive; common node for current sensing in low-side configuration

Key Features

Feature	Design Value
Lowest R_DS(on) × Q_g FoM	0.35 Ω × 19 nC = 6.65 Ω·nC - minimizes combined conduction + switching loss in 65–300 kHz SMPS
Extreme dv/dt rating	≥400 V/ns - eliminates need for gate resistors or RC snubbers in high-dV/dt PFC boost stages
Industrial-grade qualification	JEDEC JESD22-A108 qualified - ensures reliability across –55 °C to +150 °C ambient in lamp ballast and display power systems
Ultra-low Q_rr diode	2.3 µC - reduces reverse recovery loss and EMI generation in synchronous rectification and half-bridge topologies

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
STP5NK50ZFP	R_DS(on) = 0.95 Ω, Q_g = 22 nC, V_DS = 500 V, Zener-protected avalanche	Higher conduction loss; lower switching speed; less suitable for >100 kHz PFC	Prefer where cost sensitivity outweighs efficiency targets and thermal headroom exists
IXTP50N10P	R_DS(on) = 0.1 Ω, V_DS = 100 V, Q_g = 65 nC - not voltage-compatible	Cannot replace in 400 V DC-link systems due to insufficient breakdown rating	Not recommended as direct alternative; only viable in low-voltage (<150 V) industrial motor drives

Compared with STP5NK50ZFP and IXTP50N10P, IPP50R350CPHKSA1 delivers superior FoM (6.65 vs. 20.9 Ω·nC) and higher voltage margin, making it optimal for compact, high-efficiency 400 V PFC and resonant converters where thermal management and EMI control are critical.

FAQ

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

The IPP50R350CPHKSA1 supports 6 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This value reflects derating from the 10 A rating at 25 °C due to thermal resistance (R_thJC = 1.4 K/W) and junction temperature limit of 150 °C.

Does this MOSFET require a gate resistor for safe operation?

A gate resistor is recommended to control dV/dt and prevent oscillation, though not strictly required due to its intrinsic dv/dt ruggedness (≥400 V/ns). Typical values range from 10 Ω to 47 Ω depending on driver strength and layout parasitics - confirmed by Infineon's application note AN2015-04 for CoolMOS™ CP devices.

Is the drain-source breakdown voltage tested at elevated temperature?

Yes, V_(BR)DSS is characterized from –60 °C to +150 °C, with minimum 440 V at T_j = 150 °C. The datasheet Figure 12 shows V_BR(DSS) decreasing linearly with temperature at ~0.5 V/°C, ensuring 500 V rating at room temperature and sufficient margin at full operating range.

Can the integrated body diode replace an external fast recovery diode in a buck converter?

No - while the body diode has t_rr = 250 ns and Q_rr = 2.3 µC, its forward voltage (V_SD = 0.9–1.2 V) is higher than Schottky alternatives, and its reverse recovery behavior is not optimized for unidirectional freewheeling. External diodes remain preferred for high-efficiency buck topologies.
