Product details

Overview

IPP90R500C3XKSA1 from Infineon Technologies is a 900 V, 0.5 Ω (max @ 25 °C) CoolMOS™ C3 superjunction N-channel power MOSFET in PG-TO220 package, optimized for quasi-resonant flyback and forward SMPS topologies in PC silverbox and industrial power supplies. It delivers 6.6 A continuous drain current at T_C = 100 °C, 68 nC total gate charge, and extreme dv/dt ruggedness up to 50 V/ns.

For engineers reviewing the IPP90R500C3XKSA1 datasheet, IPP90R500C3XKSA1 pinout, IPP90R500C3XKSA1 application, or IPP90R500C3XKSA1 equivalent, key selection criteria include R_DS(on) vs. temperature stability, avalanche energy rating (388 mJ single-pulse), gate charge profile for ZVS/ZCS compatibility, and TO-220 thermal resistance (0.8 K/W junction-to-case).

Technical Context

This device implements Infineon's third-generation CoolMOS™ C3 technology, featuring optimized charge balancing for ultra-low R_DS(on) × Q_g figure-of-merit (0.5 Ω × 68 nC). Its 900 V breakdown voltage and 50 V/ns dv/dt rating enable robust operation in high-voltage resonant converters with fast switching transitions.

The integrated body diode exhibits 480 ns reverse recovery time and 8.5 µC Q_rr, supporting moderate-frequency hard-switched and quasi-resonant operation. Thermal design is anchored by a verified 0.8 K/W R_thJC, enabling 156 W power dissipation at T_C = 25 °C with appropriate heatsinking.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	900 V - supports 400 V DC-link designs with ≥2× safety margin for transient overvoltage
R_DS(on) max @ 25 °C	0.5 Ω - enables low conduction loss in 6.6 A continuous applications at room temperature
Q_g typ	68 nC - reduces gate drive power and allows use with standard 1–2 A peak gate drivers
E_AS single-pulse	388 mJ - withstands inductive energy spikes without failure in flyback snubberless designs
dv/dt ruggedness	50 V/ns - ensures reliable operation under fast voltage transients in high-frequency resonant topologies
R_thJC	0.8 K/W - permits efficient heat transfer to heatsink; enables 156 W P_tot at T_C = 25 °C
I_D cont @ 100 °C	6.8 A - defines usable current capability in thermally constrained industrial SMPS enclosures

Pinout & Package

IPP90R500C3XKSA1 uses the PG-TO220 package (standard 3-pin through-hole outline, isolated tab, lead-free plating per RoHS). The metal tab is electrically connected to the drain terminal.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main high-side current path	Electrically connected to package tab; requires insulated mounting or direct heatsink connection with isolation washer
Source	Reference node for gate drive and current sensing	Low-inductance return path; critical for stable gate control and accurate current monitoring
Gate	Control electrode for channel modulation	High-impedance input requiring <100 nA leakage; sensitive to ESD and ringing-requires RC snubber or gate resistor

Key Features

Feature	Design Value
Ultra-low R_DS(on) × Q_g	0.5 Ω × 68 nC - minimizes combined conduction and switching losses in 65–100 kHz SMPS
Extreme dv/dt rating	50 V/ns - eliminates false turn-on risk in high-slew-rate resonant converters without extra gate clamping
High peak current capability	24 A pulsed - supports overload and startup surge currents in consumer power adapters
JEDEC-qualified reliability	Qualified per J-STD-20/JESD22 - validated for temperature cycling, humidity, and solderability in industrial environments
Integrated fast-recovery body diode	t_rr = 480 ns, Q_rr = 8.5 µC - reduces dead-time losses and EMI in synchronous rectification and QR flyback

Applications

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
IPP90R600C3XKSA1	R_DS(on) max = 0.6 Ω; Q_g = 57 nC; same 900 V rating and TO-220 package	Higher R_DS(on) increases conduction loss but lower Q_g improves light-load efficiency	Select when optimizing for partial-load efficiency in variable-output adapters
IPW90R500C3FKSA1	Same R_DS(on)/Q_g specs; PG-TO247-3 package; higher P_tot (214 W) and lower R_thJC (0.45 K/W)	Enables higher power density and better thermal headroom in space-constrained industrial designs	Select when >156 W dissipation or forced-air cooling is required

Compared with IPP90R600C3XKSA1, this part trades 100 mΩ lower R_DS(on) for 11 nC higher Q_g; versus IPW90R500C3FKSA1, it offers identical electrical performance in a lower-cost, lower-power TO-220 footprint-ideal for cost-sensitive 300 W-class designs.

FAQ

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

The IPP90R500C3XKSA1 supports 6.8 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This value assumes proper heatsinking and accounts for R_DS(on) increase with junction temperature-actual usable current depends on layout thermal resistance and ambient conditions.

Is the body diode suitable for synchronous rectification?

No-the integrated body diode has 480 ns t_rr and 8.5 µC Q_rr, making it unsuitable for high-frequency synchronous rectification. It is designed for freewheeling in QR flyback and forward topologies where reverse recovery occurs infrequently and at controlled di/dt.

Does this MOSFET require a negative gate turn-off voltage?

No-Infineon specifies V_GS = ±30 V absolute maximum, but gate drive is typically 0 V (off) and +10 to +15 V (on). A negative turn-off voltage is not required due to the device's high dv/dt immunity and low gate threshold variation (2.5–3.5 V).

Can IPP90R500C3XKSA1 replace older CoolMOS™ C2 devices?

Yes-it is a direct drop-in replacement for IPP90R500C2 in most applications, offering identical pinout, voltage rating, and R_DS(on), plus improved Q_g and dv/dt ruggedness. No circuit redesign is needed, though gate resistor values may be optimized for faster switching.
