Product details

Overview

IPP90R1K0C3XKSA1 from Infineon Technologies is a 900 V, 1.0 Ω (max @ 25 °C) CoolMOS™ superjunction power MOSFET in PG-TO220 package, optimized for quasi-resonant flyback and forward SMPS topologies in PC silverbox and industrial power supplies. It delivers ultra-low gate charge (34 nC typ), extreme dv/dt ruggedness (50 V/ns), and high peak current capability (12 A pulsed).

For engineers reviewing the IPP90R1K0C3XKSA1 datasheet, IPP90R1K0C3XKSA1 pinout, IPP90R1K0C3XKSA1 application, or IPP90R1K0C3XKSA1 equivalent, key selection criteria include R_DS(on) vs. temperature stability, avalanche energy rating (97 mJ single-pulse), gate charge profile, and TO220 thermal resistance (1.4 K/W junction-to-case).

Technical Context

This 900 V superjunction MOSFET employs CoolMOS™ charge-compensation technology to achieve low R_DS(on) × Q_g figure-of-merit (0.78 Ω × 34 nC = 26.5 Ω·nC typ). Its robust dv/dt rating (50 V/ns) enables reliable operation in hard-switched and resonant converters without snubbers.

The device integrates a fast-recovery body diode (t_rr = 340 ns, Q_rr = 4.1 µC) with controlled reverse recovery behavior, supporting ZVS/ZCS transitions in QR flyback and LLC designs. Thermal performance is defined by R_thJC = 1.4 K/W and R_thJA = 62 K/W (leaded).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	900 V - supports 400 V DC-link systems with ≥2× voltage margin for surge and ringing
R_DS(on) max @ 25 °C	1.0 Ω - enables low conduction loss at 3.3 A continuous drain current (T_C = 25 °C)
Q_g typ	34 nC - reduces gate drive power and switching losses in high-frequency SMPS (>100 kHz)
E_AS single-pulse	97 mJ - withstands unclamped inductive switching stress without failure in flyback snubberless designs
dv/dt ruggedness	50 V/ns - prevents spurious turn-on during fast voltage transients in high-side configurations
t_rr / Q_rr	340 ns / 4.1 µC - minimizes diode recovery loss and EMI in discontinuous conduction mode (DCM) operation
R_thJC	1.4 K/W - allows 89 W power dissipation at T_C = 25 °C, critical for thermally constrained TO220 layouts

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 Drain and serves as primary heat path to heatsink.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives 10 V logic-level drive; low input capacitance (C_iss = 850 pF) eases driver selection
Pin 2 (Drain / Tab)	High-voltage power terminal	Connected to heatsink; requires electrical isolation when mounted to chassis or shared thermal plane
Pin 3 (Source)	Reference node for gate drive	Serves as return path for gate current and sense point for source degeneration or current monitoring

Key Features

Feature	Design Value
Ultra-low R_DS(on) × Q_g	26.5 Ω·nC typ - directly improves efficiency in 65–300 kHz SMPS by reducing combined conduction + switching loss
Extreme dv/dt rating	50 V/ns - eliminates need for external gate resistors or RC snubbers in high-di/dt applications
JEDEC-qualified reliability	Qualified per J-STD-20/JESD22 - ensures long-term stability in industrial and consumer power supplies
Low Q_gd/Q_g ratio	15 nC / 34 nC ≈ 44% - enhances Miller immunity and enables faster, more predictable turn-off
Enhanced body diode softness	Controlled reverse recovery (I_rrm = 21 A, t_rr = 340 ns) - reduces voltage overshoot and EMI in QR flyback freewheeling

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
STP9NK90ZFP	900 V, 1.1 Ω R_DS(on), 42 nC Q_g, Zener-protected gate	Higher gate charge increases driver loss; lower dv/dt rating (25 V/ns) limits high-frequency use	Preferred where gate protection is prioritized over efficiency in cost-sensitive consumer adapters
IXTH1N90P	900 V, 1.2 Ω R_DS(on), 28 nC Q_g, planar construction	Lower Q_g but higher R_DS(on); no integrated body diode optimization for QR operation	Used in fixed-frequency forward converters where diode recovery is less critical than gate drive simplicity

Compared with STP9NK90ZFP and IXTH1N90P, IPP90R1K0C3XKSA1 offers the lowest R_DS(on) × Q_g product and superior dv/dt ruggedness-making it optimal for high-efficiency, high-frequency QR flyback and industrial SMPS where thermal headroom and switching noise are tightly constrained.

FAQ

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

The maximum continuous drain current I_D is 3.6 A at T_C = 100 °C, as specified in the absolute maximum ratings table. This value reflects thermal derating due to reduced channel conductivity and increased R_DS(on) at elevated temperatures, and must be applied with appropriate heatsinking to maintain junction temperature below 150 °C.

Does IPP90R1K0C3XKSA1 have an integrated gate protection diode?

No, IPP90R1K0C3XKSA1 does not include an integrated gate-source Zener diode. Its gate oxide is rated for ±30 V, and external gate protection (e.g., 18 V TVS) is recommended in noisy environments or when driving with non-isolated controllers to prevent gate oxide rupture during transients.

How does the body diode performance compare to standard silicon MOSFETs?

This device features a tailored body diode with t_rr = 340 ns and Q_rr = 4.1 µC at I_F = 3.3 A, significantly softer and faster than conventional planar MOSFETs. Its reverse recovery is optimized for quasi-resonant operation, reducing voltage spikes and EMI in flyback freewheeling paths without requiring external Schottky catch diodes.

Is the PG-TO220 package lead-free and RoHS compliant?

Yes, IPP90R1K0C3XKSA1 uses Pb-free lead plating and complies with RoHS Directive 2011/65/EU. The package is qualified for wave soldering at 260 °C for 10 s at 1.6 mm from case, and its thermal interface meets JEDEC J-STD-20 reflow profiles for lead-free assembly processes.
