Product details

Overview

IPP90R1K2C3XKSA2 from Infineon Technologies is a 900 V, 1.2 Ω R_DS(on) CoolMOS™ C3 superjunction power MOSFET in PG-TO220 package, optimized for quasi-resonant flyback and forward SMPS topologies. It delivers 5.1 A continuous drain current at T_C = 25 °C, 28 nC total gate charge, and 68 mJ single-pulse avalanche energy-enabling high-efficiency, compact AC/DC adapters for PC silverbox and industrial SMPS.

For engineers reviewing the IPP90R1K2C3XKSA2 datasheet, IPP90R1K2C3XKSA2 pinout, IPP90R1K2C3XKSA2 application, or IPP90R1K2C3XKSA2 equivalent, key selection criteria include its 900 V V_(BR)DSS, ultra-low Q_g/R_DS(on) figure-of-merit, dv/dt ruggedness up to 50 V/ns, and JEDEC-qualified reliability for high-voltage switching in thermally constrained environments.

Technical Context

This device implements a superjunction trench-gate structure with optimized charge compensation for reduced conduction and switching losses. Its 28 nC Q_g and 12 nC Q_gd enable fast, low-loss hard-switching at high frequencies, while the 1.5 K/W R_thJC supports high-power density designs without forced cooling.

The integrated body diode exhibits 310 ns t_rr and 3.7 µC Q_rr, making it suitable for synchronous rectification and ZVS-capable topologies. Its 50 V/ns dv/dt rating ensures robust operation under fast voltage transients in bridge-leg configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
V_(BR)DSS	900 V - Withstands full mains-related DC link voltages (e.g., 400 V bus + 20% surge) in offline SMPS.
R_DS(on), max @ 25 °C	1.2 Ω - Enables <5.1 A continuous conduction with ≤6.2 W conduction loss at T_C = 25 °C.
Q_g, typ	28 nC - Reduces gate drive power and enables use of low-cost, low-current drivers in 65–100 kHz QR flyback designs.
E_AS, single pulse	68 mJ - Supports reliable unclamped inductive switching in PFC and LLC primary-side applications.
R_thJC	1.5 K/W - Allows ≥50 W dissipation with ≤75 K junction-to-case temperature rise using standard TO220 heatsinking.
t_r / t_f	20 ns / 40 ns - Minimizes switching transition time, reducing overlap loss in hard-switched converters.
V_GS(th)	2.5–3.5 V - Ensures clean turn-on with standard 5 V logic-level gate drivers and avoids spurious conduction near ground.

Pinout & Package

Package: PG-TO220 (3-pin, through-hole, isolated tab). Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source. The metal tab is electrically connected to the Drain terminal and must be insulated from heatsink unless circuit topology requires common-drain configuration.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control electrode	Receives 10 V gate drive to fully enhance channel; 2.5–3.5 V threshold enables compatibility with 3.3 V/5 V controllers.
Pin 2 (Drain / Tab)	High-voltage power terminal	Connected directly to internal die drain; tab must be electrically isolated unless used as high-side switch return path.
Pin 3 (Source)	Reference and return path	Serves as signal reference for gate driver and current sense; low-inductance layout critical for dv/dt stability.

Key Features

Feature	Design Value
Ultra-low R_DS(on) × Q_g FoM	33.6 Ω·nC - Delivers best-in-class efficiency trade-off for 900 V MOSFETs in 65–130 kHz SMPS.
Extreme dv/dt ruggedness	50 V/ns - Prevents false turn-on during high-slew-rate commutation in half-bridge and LLC resonant circuits.
JEDEC-qualified reliability	J-STD-20/JESD22 compliant - Validated for long-term operation in consumer and industrial power supplies per AEC-Q101 stress test conditions.
Integrated fast-recovery body diode	t_rr = 310 ns, Q_rr = 3.7 µC - Reduces reverse recovery loss and EMI in quasi-resonant and active-clamp forward converters.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP9NK90ZFP	900 V, 1.4 Ω R_DS(on), 42 nC Q_g, TO-220FP package (non-isolated tab)	Higher conduction loss and gate drive requirement; lower dv/dt rating (25 V/ns)	Acceptable where cost is prioritized over efficiency and board space; requires isolation washer for heatsink mounting.
IXTH12N90L2	900 V, 1.1 Ω R_DS(on), 48 nC Q_g, TO-247 package	Larger footprint and higher gate drive power; superior thermal resistance (0.8 K/W) but no integrated diode optimization	Better for high-temperature, high-power (>600 W) applications where heatsink area is available and diode recovery is externally managed.

Compared with STP9NK90ZFP and IXTH12N90L2, IPP90R1K2C3XKSA2 offers the lowest R_DS(on)×Q_g FoM and highest dv/dt ruggedness in TO220 form factor-making it optimal for space-constrained, high-efficiency QR flyback and forward converters requiring minimal gate drive overhead and robust transient immunity.

FAQ

Is IPP90R1K2C3XKSA2 RoHS-compliant and lead-free?

Yes. The device uses Pb-free lead plating and complies fully with RoHS Directive 2011/65/EU. Its packaging and assembly processes meet J-STD-20 reflow profile requirements for lead-free soldering, including wave soldering at leads only (260 °C for 10 s at 1.6 mm from case).

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, derated from 5.1 A at 25 °C per the thermal curve on page 4 of the datasheet. This reflects safe operation within the SOA limit when mounted on a heatsink providing ≤1.5 K/W thermal resistance.

Does IPP90R1K2C3XKSA2 have an integrated body diode, and what are its key parameters?

Yes. It features an integrated fast-recovery body diode with V_SD = 0.8–1.2 V at I_F = 2.8 A and T_J = 25 °C, t_rr = 310 ns, Q_rr = 3.7 µC, and I_RRM = 19 A. These values are measured under standardized conditions (V_R = 400 V, di_F/dt = 100 A/µs) and support soft-switching in QR and active-clamp topologies.

Can IPP90R1K2C3XKSA2 replace older CoolMOS™ C2 devices in existing designs?

Yes, with minor layout review. IPP90R1K2C3XKSA2 is a direct drop-in replacement for IPP90R1K2C2XKSA2, offering identical pinout, package, and voltage/current ratings, plus improved Q_g (28 nC vs. 32 nC) and dv/dt ruggedness (50 V/ns vs. 40 V/ns). No gate driver or snubber changes are required.
