Product details

Overview

IPP90R1K2C3XKSA1 from Infineon Technologies is a 900 V, 1.2 Ω (max) CoolMOS™ superjunction N-channel power MOSFET in PG-TO220 package, optimized for quasi-resonant flyback and forward SMPS topologies. It delivers ultra-low gate charge (28 nC typ), extreme dv/dt ruggedness (50 V/ns), and high peak current capability (10 A pulsed), enabling high-efficiency, compact AC/DC adapters and industrial switch-mode power supplies.

For engineers reviewing the IPP90R1K2C3XKSA1 datasheet, IPP90R1K2C3XKSA1 pinout, IPP90R1K2C3XKSA1 application, or IPP90R1K2C3XKSA1 equivalent, key selection criteria include R_DS(on) at 150 °C (2.5 Ω max), avalanche energy rating (68 mJ single-pulse), thermal resistance (1.5 K/W junction-to-case), and JEDEC-qualified reliability for consumer and industrial SMPS designs.

Technical Context

This device employs Infineon's CoolMOS™ C3 technology, featuring optimized charge balancing for reduced R_DS(on) × Q_g figure-of-merit. Its 900 V breakdown voltage and 50 V/ns dv/dt rating support robust operation in high-voltage, high-frequency resonant converters without external snubbers.

The integrated fast-recovery body diode (t_rr = 310 ns, Q_rr = 3.7 µC) enables efficient synchronous rectification in QR flyback designs. Thermal design is supported by low R_thJC (1.5 K/W) and defined SOA curves up to 10 ms pulse width at T_C = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	900 V - supports 400 V DC-link systems with ≥2× safety margin in industrial SMPS
R_DS(on) max @ 25 °C	1.2 Ω - enables low conduction loss in <50 W QR flyback primary switches
Q_g typ	28 nC - reduces gate drive power and EMI in 65–130 kHz switching applications
E_AS single-pulse	68 mJ - sustains unclamped inductive switching stress without failure in forward converters

Pin 3 (Source)	Reference node / return path	Serves as common reference for gate drive and current sensing; tied to PCB ground plane for thermal and EMI control

Key Features

Feature	Design Value
Ultra-low R_DS(on) × Q_g	Optimizes efficiency in 65–130 kHz QR flyback designs where both conduction and switching losses dominate
JEDEC-qualified reliability	Validated per J-STD-20/JESD22 for consumer and industrial temperature cycling and moisture sensitivity
Enhanced dv/dt immunity	50 V/ns rating prevents spurious turn-on in high-noise PFC + LLC cascaded topologies
Fast body diode recovery	t_rr = 310 ns and Q_rr = 3.7 µC reduce reverse recovery loss and EMI in discontinuous conduction mode
Low thermal resistance	R_thJC = 1.5 K/W enables compact heatsink integration in space-constrained 30–65 W adapters

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
STP9NK90ZFP	900 V, 1.2 Ω, but higher Q_g (45 nC) and no JEDEC qualification	Limited to non-automotive industrial use; lower dv/dt rating (25 V/ns)	Lower cost but requires larger gate driver and snubber network
IXTH1N90P	900 V, 1.4 Ω, higher R_thJC (2.0 K/W), no integrated diode optimization	Not recommended for QR flyback due to slower t_rr (520 ns)	Acceptable for fixed-frequency forward converters with soft-switching

Compared with STP9NK90ZFP and IXTH1N90P, IPP90R1K2C3XKSA1 offers superior switching efficiency (via lower Q_g and optimized C_oss) and system-level reliability (JEDEC qualification, 50 V/ns dv/dt), making it preferred for compact, high-density QR flyback and industrial forward designs.

FAQ

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

The maximum continuous drain current I_D is 3.2 A at T_C = 100 °C, derived from thermal derating curves and R_DS(on) increase with junction temperature. This value assumes adequate heatsinking and accounts for increased on-resistance at elevated temperatures, ensuring safe operation within SOA limits.

Does IPP90R1K2C3XKSA1 have an integrated body diode, and what are its key recovery parameters?

Yes, it features an optimized integrated body diode with reverse recovery time t_rr = 310 ns and reverse recovery charge Q_rr = 3.7 µC at I_F = 2.8 A and di/dt = 100 A/µs. These values enable efficient operation in discontinuous conduction mode flyback converters without external diode supplementation.

Is this device suitable for use in a 400 V DC-link PFC boost stage?

No - while rated for 900 V blocking, the IPP90R1K2C3XKSA1 is not optimized for continuous high-current PFC operation due to its relatively high R_DS(on) and lack of dedicated PFC-specific gate charge profile. It is best suited for downstream isolated DC/DC conversion stages.

What is the gate threshold voltage range, and how does it affect drive circuit design?

V_GS(th) ranges from 2.5 V to 3.5 V at I_D = 0.31 mA. This tight threshold window ensures consistent turn-on behavior across temperature and process variation, allowing reliable 10 V gate drive without overvoltage risk or need for negative turn-off bias in standard PWM controllers.
