Product details

Overview

IPP90R500C3 from Infineon Technologies is a 900 V, 0.5 Ω (max) 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 6.8 A continuous drain current at T_C = 100 °C, 68 nC total gate charge, and 388 mJ single-pulse avalanche energy.

For engineers reviewing the IPP90R500C3 datasheet, IPP90R500C3 pinout, IPP90R500C3 application, or IPP90R500C3 equivalent, key selection criteria include R_DS(on) vs. temperature stability, dv/dt ruggedness (50 V/ns), E_AS capability, gate charge profile, and thermal resistance (R_thJC = 0.8 K/W) for high-efficiency, high-reliability offline converters.

Technical Context

This 900 V superjunction MOSFET employs Infineon's CoolMOS™ C3 technology to minimize conduction and switching losses simultaneously via ultra-low Q_g (68 nC typ.) and optimized C_oss (83 pF typ.), enabling high-frequency operation in QR flyback designs up to 100 kHz. Its 50 V/ns dv/dt rating and 388 mJ E_AS support robust operation under transient overvoltage and hard-switching stress.

The device integrates a fast-recovery body diode with t_rr = 480 ns and Q_rr = 8.5 µC, reducing switching loss in synchronous rectification and half-bridge configurations. Thermal performance is anchored by R_thJC = 0.8 K/W, allowing direct heatsink mounting for industrial SMPS with >90% efficiency targets.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	900 V - supports universal AC input (85–265 VAC) with 20% margin in offline SMPS
R_DS(on) max @ 25°C	0.5 Ω - enables low conduction loss at 6.6 A DC output in 100–300 W adapters
Q_g typ	68 nC - reduces gate drive power and enables use of low-cost 1A drivers in QR controllers
E_AS single pulse	388 mJ - withstands repetitive line surges and transformer leakage spikes without failure
dv/dt ruggedness	50 V/ns - prevents false turn-on during high-slew-rate switching in high-density layouts
R_thJC	0.8 K/W - allows 11 W continuous dissipation at 100 °C case temperature with minimal heatsink
t_rr	480 ns - limits reverse recovery loss in secondary-side synchronous rectification

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 logic-level drive; 1.3 Ω internal gate resistance minimizes ringing
Pin 2 (Drain / Tab)	High-voltage power terminal	Connected to primary-side HV rail; tab provides thermal path and must be electrically isolated unless used as heatsink return
Pin 3 (Source)	Reference node for gate drive	Serves as local ground reference for driver IC; low-inductance layout critical for dv/dt immunity

Key Features

Feature	Design Value
Ultra-low R_DS(on) × Q_g	0.5 Ω × 68 nC = 34 Ω·nC figure-of-merit - enables higher efficiency than previous-gen 900 V MOSFETs at 65–100 kHz
JEDEC-qualified reliability	Qualified per J-STD-20/JESD22 - validated for 10-year field life in consumer and industrial SMPS
Enhanced avalanche ruggedness	388 mJ single-pulse E_AS at 50 V - eliminates need for external snubbers in flyback clamp circuits
Pb-free & RoHS compliant	Lead-free plating on leads and RoHS-compliant materials - meets EU and global environmental compliance mandates
High peak current capability	I_D,pulse = 24 A - supports 3× overload tolerance during startup and short-circuit events

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
IPP65R099C7	650 V rating, 0.099 Ω R_DS(on), lower Q_g (45 nC), smaller die size	Not suitable for 900 V bus designs; limited to <265 VAC input with reduced margin	Select only for cost-sensitive 650 V systems where voltage margin is not critical
STP9NK90Z	Zener-protected 900 V superjunction MOSFET, higher R_DS(on) (0.85 Ω), no JEDEC qualification data published	Lacks documented avalanche energy rating and industrial reliability validation	Acceptable for non-critical consumer applications but not recommended for industrial or medical-grade designs

Compared with IPP65R099C7 and STP9NK90Z, the IPP90R500C3 uniquely combines 900 V rating, JEDEC qualification, 388 mJ E_AS, and 0.5 Ω R_DS(on)-making it the only option qualified for sustained operation in universal-input industrial SMPS with surge immunity requirements.

FAQ

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

The IPP90R500C3 supports 6.8 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This value assumes proper PCB copper area and heatsinking to maintain junction temperature below 150 °C under steady-state conditions.

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

No. The IPP90R500C3 operates with 0 V to +10 V gate drive and does not require negative turn-off bias. Its V_GS(th) range (2.5–3.5 V) and low gate threshold variation ensure reliable turn-on with standard 10 V drivers, and its 50 V/ns dv/dt rating prevents spurious turn-on without negative gate clamping.

Can the body diode be used for synchronous rectification?

Yes-the integrated body diode has t_rr = 480 ns and Q_rr = 8.5 µC at T_J = 25 °C, making it suitable for secondary-side synchronous rectification in flyback converters up to 100 kHz. However, external Schottky diodes remain preferred for <50 W designs due to lower V_SD (0.8–1.2 V).

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

Yes. The IPP90R500C3 uses Pb-free lead plating and complies fully with RoHS Directive 2011/65/EU. Lead-free soldering is supported with wave soldering limited to 260 °C for 10 s at 1.6 mm from the case, as verified per J-STD-020.
