Product details

Overview

IPP50R299CPXKSA1 from Infineon Technologies is a 500 V, 14 A (continuous), 299 mΩ (R_DS(on) max @ V_GS = 10 V) CoolMOS™ C7 superjunction MOSFET in TO-220FP package, optimized for high-efficiency SMPS in server power supplies, telecom rectifiers, and industrial AC-DC adapters.

For engineers reviewing the IPP50R299CPXKSA1 datasheet, IPP50R299CPXKSA1 pinout, IPP50R299CPXKSA1 application, or IPP50R299CPXKSA1 equivalent, key selection criteria include R_DS(on), Q_g (39 nC), E_oss (38 nJ), t_rr (105 ns), and thermal resistance R_thJC (1.2 K/W).

Technical Context

This device employs Infineon's 7th-generation CoolMOS™ charge-compensation technology with optimized cell pitch and reduced gate-drain charge (Q_gd = 11 nC), enabling fast switching with low commutation losses in hard-switched PFC and LLC resonant converters.

It features an integrated fast-recovery body diode (t_rr = 105 ns, Q_rr = 120 nC) and supports ZVS operation in phase-shifted full-bridge topologies, with gate threshold voltage V_GS(th) = 3.5 V (typ) and zero-temperature-coefficient R_DS(on) behavior above 100 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	500 V - withstands peak line voltages up to 400 VAC mains with ≥25% margin in offline SMPS.
R_DS(on) max	299 mΩ @ V_GS = 10 V, T_j = 100 °C - enables <1.5 W conduction loss at 14 A continuous drain current.
Q_g	39 nC - supports 100–300 kHz switching with moderate gate drive strength (e.g., 1–2 A peak).
E_oss	38 nJ @ V_DS = 400 V - reduces turn-on switching loss in hard-switched topologies.
t_rr	105 ns - limits reverse recovery overshoot and EMI in bridge-leg configurations.
R_thJC	1.2 K/W - allows 75 W power dissipation at ΔT = 90 K with standard heatsinking.
I_D cont	14 A @ T_C = 25 °C - rated for continuous operation in forced-air-cooled 500–1000 W power stages.

Pinout & Package

TO-220FP (Full-Pak) package with isolated drain tab, 3-pin through-hole mounting, and creepage/clearance compliant with IEC 60950-1 for reinforced insulation.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Power return path for load current	Low-inductance connection point for source loop minimization; ties directly to PCB ground plane.
Pin 2 (Gate)	Control input for channel conduction	High-impedance MOSFET gate requiring RC snubber (e.g., 10 Ω + 100 pF) to suppress ringing.
Pin 3 (Drain)	Main high-voltage power terminal	Internally connected to metal tab; electrically isolated from case but thermally coupled for heatsink mounting.

Key Features

Feature	Design Value
Optimized Q_g/R_DS(on) ratio	39 nC / 299 mΩ = 0.13 - balances switching and conduction loss across 100–250 kHz range.
Reduced Q_gd	11 nC - lowers Miller plateau time and improves dv/dt immunity in high-side configurations.
Fast body diode	t_rr = 105 ns, Q_rr = 120 nC - enables synchronous rectification emulation without external diode in LLC half-bridge.
Zero-tempco R_DS(on)	Stable on-resistance above 100 °C - simplifies thermal derating and improves parallel operation reliability.
Lead-free & RoHS-compliant	Meets EU Directive 2011/65/EU - suitable for consumer and industrial products requiring environmental compliance.

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) = 550 mΩ @ 10 V, higher Q_g (52 nC), no fast diode (t_rr > 500 ns)	Limited to lower-power (<150 W) flyback designs due to higher conduction and switching loss	Lower-cost option where efficiency >94% is not required and layout space permits larger heatsink
IXFH30N50P	Higher R_DS(on) (300 mΩ), higher E_oss (120 nJ), TO-247 package (larger footprint)	Better thermal performance (R_thJC = 0.5 K/W) but requires more PCB area and costlier assembly	Preferred when junction temperature must stay below 110 °C under sustained 18 A peak loads

Compared with STP5NK50ZFP and IXFH30N50P, IPP50R299CPXKSA1 delivers best-in-class efficiency per mm² in TO-220FP form factor, with superior diode softness and tighter R_DS(on) distribution for production consistency.

FAQ

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

A gate resistor of 10–22 Ω is recommended to limit peak gate current to <2 A while suppressing oscillation. Lower values (≤5 Ω) may cause ringing due to PCB trace inductance; higher values (>47 Ω) increase switching time and losses. Layout-dependent optimization using a 100 pF capacitor in parallel with the resistor is advised for noise-sensitive applications.

Does IPP50R299CPXKSA1 require a negative gate turn-off voltage?

No. The device operates reliably with 0 V to 10 V gate drive and does not require negative turn-off bias. Its V_GS(th) of 3.5 V (typ) and low Miller charge ensure clean turn-off even with 0 V gate drive, though a small negative offset (–2 V) can improve noise immunity in high-dv/dt environments.

Can this MOSFET be paralleled for higher current handling?

Yes-its positive temperature coefficient of R_DS(on) above 100 °C enables stable current sharing. Use matched gate resistors (±1%), symmetrical PCB layout, and individual source resistors (0.01 Ω) for current sensing and balancing. Derate total current by 15% versus sum of individual ratings to account for thermal coupling.

Is the TO-220FP package electrically isolated?

The TO-220FP package provides electrical isolation between the drain-connected metal tab and the leads (≥2500 V RMS, per IEC 60950-1), but the tab remains at drain potential. It is not a fully insulated package like TO-247-4L; isolation is achieved via internal molding compound, not ceramic substrate.
