Product details

Overview

IPA90R800C3 from Infineon Technologies is a 900 V, 0.8 Ω (max) CoolMOS™ superjunction power MOSFET in PG-TO220 FP package, optimized for quasi-resonant flyback and forward SMPS topologies in PC silverbox and industrial power supplies. It delivers 6.9 A continuous drain current at 25 °C, 42 nC total gate charge, and extreme dv/dt ruggedness up to 50 V/ns.

For engineers reviewing the IPA90R800C3 datasheet, IPA90R800C3 pinout, IPA90R800C3 application, or IPA90R800C3 equivalent, key selection criteria include R_DS(on) vs. temperature stability, avalanche energy rating (157 mJ), gate charge profile, and TO-220 FP thermal resistance (3.8 K/W junction-to-case).

Technical Context

This 900 V superjunction MOSFET employs CoolMOS™ C3 technology with optimized charge balance for low R_DS(on) × Q_g figure-of-merit (0.8 Ω × 42 nC). Its 50 V/ns dv/dt rating enables robust operation in high-frequency resonant converters without spurious turn-on.

The device integrates a fast-recovery body diode (t_rr = 360 ns, Q_rr = 5.3 µC) and supports repetitive avalanche (E_AR = 1.4 mJ/pulse) under controlled conditions. Thermal design leverages 3.8 K/W R_thJC and JEDEC-qualified reliability for industrial SMPS.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	900 V - supports 400 V DC-link designs with ≥2× voltage margin for surge and ringing
R_DS(on) max @ 25°C	0.8 Ω - enables low conduction loss in 6–8 A continuous output SMPS stages
Q_g typ	42 nC - reduces gate drive power and allows use with standard 1–2 A peak gate drivers
E_AS	157 mJ - provides single-pulse avalanche robustness during transient overvoltage events
dv/dt ruggedness	50 V/ns - prevents false triggering in high-slew-rate QR flyback primary switches
R_thJC	3.8 K/W - enables 33 W continuous dissipation at T_C = 100 °C with minimal heatsink
t_rr	360 ns - limits reverse recovery loss in hard-switched forward converters

Pinout & Package

IPA90R800C3 uses the PG-TO220 FP (Full-Pak) package: isolated tab, vertical lead frame, through-hole mounting, with thermal pad electrically connected to drain. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives 10 V logic-level drive; 1.3 Ω internal gate resistance limits ringing
Pin 2 (Drain / Tab)	High-voltage power terminal	Electrically connected to metal tab; requires insulated mounting for floating applications
Pin 3 (Source)	Reference and return path	Serves as local ground reference for gate driver; carries full load current

Key Features

Feature	Design Value
Ultra-low R_DS(on) × Q_g	0.8 Ω × 42 nC = 33.6 Ω·nC - minimizes combined switching + conduction loss in 65–100 kHz SMPS
Extreme dv/dt rating	50 V/ns - eliminates need for external gate snubbers in QR flyback primary side
JEDEC-qualified reliability	Qualified per J-STD-20/JESD22 - validated for industrial temperature cycling and humidity exposure
Low gate charge asymmetry	Q_gs = 5 nC, Q_gd = 18 nC - enables predictable Miller plateau timing for precise dead-time control

Applications

PC Silverbox Power Supply

Use Scenario: 300–500 W AC/DC front-end with quasi-resonant flyback topology.

IC Role / Device Role / Timing Role: Primary-side high-voltage switch operating at 65–100 kHz with zero-voltage switching.

Use Value: 0.8 Ω R_DS(on) and 42 nC Q_g reduce total losses by ~12% vs. legacy 900 V MOSFETs at 70 °C case temperature.

Use Scenario: 200–400 W open-frame industrial power supply with forward converter.

IC Role / Device Role / Timing Role: Main power switch handling 400 V DC-link, requiring high avalanche margin and thermal stability.

Use Value: 157 mJ E_AS and 3.8 K/W R_thJC support reliable operation under line surges and 100% load step without derating.

Consumer Adapter

LED Driver (High-Voltage)

Use Scenario: Compact 65 W USB-C PD adapter using active-clamp flyback.

IC Role / Device Role / Timing Role: High-side switch managing 900 V blocking and sub-100 ns turn-off transitions.

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, 0.95 Ω R_DS(on), 58 nC Q_g, no specified dv/dt rating	Higher conduction + switching loss; less suitable for >80 kHz QR operation	Prefer where cost sensitivity outweighs efficiency targets and frequency is ≤65 kHz
IXTH8N90L2	900 V, 1.2 Ω R_DS(on), 45 nC Q_g, 30 V/ns dv/dt rating	Lower dv/dt margin increases risk of false turn-on in high-slew circuits	Acceptable only with gate snubber and conservative layout; not drop-in for IPA90R800C3

Compared with STP9NK90ZFP and IXTH8N90L2, IPA90R800C3 offers superior R_DS(on) × Q_g, certified dv/dt immunity, and lower thermal resistance-enabling higher power density and simpler gate drive in resonant SMPS.

FAQ

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

The IPA90R800C3 supports 4.4 A continuous drain current at T_C = 100 °C, as specified in its absolute maximum ratings table. This value reflects thermal limitation-not electrical saturation-and assumes proper heatsinking to maintain junction temperature below 150 °C under steady-state operation.

Is the TO-220 FP package electrically isolated?

Yes-the PG-TO220 FP package features an electrically isolated metal tab (Drain-connected), enabling direct heatsink mounting without insulating hardware. The isolation withstands ≥2.5 kV RMS per IEC 60747-17, verified during production testing.

Does IPA90R800C3 support avalanche operation in repetitive mode?

Yes-it is rated for repetitive avalanche with E_AR = 1.4 mJ per pulse at I_D = 1.4 A and V_DD = 50 V. However, each event adds measurable power loss (P_AV = E_AR × f), so thermal design must account for cumulative heating in systems with frequent transients.

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

Its body diode achieves t_rr = 360 ns and Q_rr = 5.3 µC at I_F = 4.1 A and T_J = 25 °C-significantly faster than conventional planar MOSFETs. This reduces reverse recovery loss in forward converters and improves light-load efficiency in QR flyback designs.
