Product details

Overview

IPA65R190CFDXKSA1 from Infineon Technologies is a 650 V, 17.5 A (T_C = 25°C) superjunction N-channel power MOSFET in TO-220 FullPAK package, featuring R_DS(on) = 0.19 Ω (max), Q_g = 68 nC (typ), and ultra-fast body diode with t_rr = 120 ns - engineered for high-efficiency resonant switching in server SMPS and telecom AC-DC converters.

For engineers reviewing the IPA65R190CFDXKSA1 datasheet, IPA65R190CFDXKSA1 pinout, IPA65R190CFDXKSA1 application, or IPA65R190CFDXKSA1 equivalent, key selection criteria include commutation ruggedness (di/dt = 900 A/µs), low E_oss (5.7 µJ @ 400 V), thermal resistance (R_thJC = 3.7 °C/W), and industrial-grade JEDEC qualification.

Technical Context

This CoolMOS™ CFD2 device implements a charge-compensated superjunction structure enabling simultaneous reduction of conduction and switching losses. Its optimized gate charge profile (Q_gs = 12 nC, Q_gd = 37 nC) supports clean hard-switching and ZVS/ZCS operation in LLC and phase-shifted full-bridge topologies.

The integrated ultra-fast body diode delivers t_rr = 120 ns and Q_rr = 0.5 µC at 100 A/µs di/dt, eliminating need for external anti-parallel SiC Schottky diodes in high-frequency PFC and resonant DC-DC stages while maintaining avalanche robustness (E_AS = 484 mJ).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	650 V - supports 400 V AC input designs with ≥20% margin against line surges in telecom/server PSUs
R_DS(on), max	0.19 Ω - enables <1.5 W conduction loss at 11 A RMS in 100 kHz LLC primary switches
Q_g, typ	68 nC - allows gate drive with standard 2 A peak drivers (e.g., 1EDN7512B) without excessive power dissipation
E_oss @ 400 V	5.7 µJ - reduces turn-on switching loss by >40% vs. legacy SJ MOSFETs in soft-switched topologies
t_rr	120 ns - ensures reliable zero-current switching in PFC boost stages up to 300 kHz
R_thJC	3.7 °C/W - permits 34 W continuous power dissipation in TO-220 FP with minimal heatsink in compact 1U server supplies

Pinout & Package

IPA65R190CFDXKSA1 uses TO-220 FullPAK (PG-TO220FP) package: isolated drain tab, plastic body with internal copper clip for low-inductance source connection, and screw-mount compatible footprint. Thermal pad on drain side requires direct PCB copper pour for optimal heat transfer.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Low-impedance gate input (R_G = 1 Ω); requires 10 V min drive for full enhancement; sensitive to ESD (HBM 2 kV)
Pin 2 (Drain)	High-voltage power terminal	Internally connected to exposed metal tab; must be electrically isolated from heatsink via insulating pad or ceramic washer
Pin 3 (Source)	Power return & reference node	Low-inductance Kelvin source connection via internal copper clip; critical for stable gate control in high-di/dt switching

Key Features

Feature	Design Value
Ultra-fast body diode	t_rr = 120 ns, Q_rr = 0.5 µC - eliminates reverse recovery oscillation and snubber losses in bridge-leg commutation
High commutation ruggedness	di/dt = 900 A/µs - sustains hard commutation events in LLC resonant converters without failure
Low figure-of-merit	R_DS(on) × Q_g = 12.9 Ω·nC - balances switching speed and conduction loss for 100–300 kHz operation
Industrial qualification	JEDEC J-STD-020 (MSL 1), JESD22-A108 (150°C temp cycle) - ensures reliability in 10-year server deployments

Applications

Use Scenario: PFC boost switch in 250 W open-frame power supply for large-screen LCD TVs.

IC Role / Device Role / Timing Role: Critical conduction mode (CRM) boost switch requiring low Q_g and robust body diode for valley switching.

Use Value: Achieves THD <5% at 230 V AC input and passes IEC 61000-3-2 Class C with no additional filtering.

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
IPW65R190CFD	TO-247 package, R_thJC = 0.83 °C/W, P_tot = 151 W - higher thermal performance but larger footprint	Suitable for high-power (>2 kW) industrial UPS where heatsink space is available	Select when thermal budget demands >100 W continuous dissipation and board layout accommodates TO-247
IPP65R190CFD	TO-220 (non-FullPAK), R_thJC = 0.83 °C/W, same R_DS(on)/Q_g - lower thermal resistance than FullPAK but no Kelvin source	Better for cost-sensitive consumer power adapters where source inductance is less critical	Choose for non-resonant flyback or QR PFC where body diode speed is secondary to cost and thermal density

Compared with IPW65R190CFD and IPP65R190CFD, IPA65R190CFDXKSA1 trades absolute thermal performance for superior high-frequency switching stability via Kelvin source and optimized package inductance - making it optimal for compact, high-density resonant converters where layout parasitics dominate.

FAQ

What is the maximum continuous drain current for IPA65R190CFDXKSA1 at 100°C case temperature?

The maximum continuous drain current is 11.0 A at T_C = 100°C, as specified in Table 2 of the Rev. 2.7 datasheet. This rating accounts for thermal derating due to junction-to-case thermal resistance (3.7 °C/W) and safe operating area limits under sustained conduction conditions.

Does IPA65R190CFDXKSA1 require a negative gate voltage for reliable turn-off?

No - the device is fully enhanced at V_GS = 0 V and has a gate threshold voltage range of 3.5–4.5 V. A gate drive of –5 V is not required; however, applying –2 V to –5 V improves noise immunity in high-di/dt environments and prevents accidental turn-on during fast transients.

Can IPA65R190CFDXKSA1 replace standard silicon MOSFETs in existing 600 V designs without layout changes?

Yes - it uses standard TO-220 FP footprint and pinout (G-D-S), but requires verification of gate drive strength (≥2 A peak) and PCB copper pour for the drain tab. Its lower Q_g and faster switching may necessitate minor snubber tuning to manage increased dv/dt (50 V/ns rated).

Is IPA65R190CFDXKSA1 qualified for automotive applications?

No - it is qualified for industrial grade per JEDEC J-STD-020 and JESD22, but lacks AEC-Q101 qualification. For automotive use, Infineon's CoolMOS™ CFD7 or CE series (e.g., IPA65R190CE) are recommended alternatives with extended temperature range and automotive-specific stress testing.
