Product details

Overview

IPI90R500C3 from Infineon Technologies is a 900 V, 0.5 Ω (max @ T_J = 25 °C) CoolMOS™ C3 superjunction power MOSFET in PG-TO262 package, optimized for high-efficiency 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 typical gate charge, and extreme dv/dt ruggedness up to 50 V/ns.

For engineers reviewing the IPI90R500C3 datasheet, IPI90R500C3 pinout, IPI90R500C3 application, or IPI90R500C3 equivalent, key selection criteria include R_DS(on) vs. temperature stability, avalanche energy rating (388 mJ single-pulse), gate charge minimization for ZVS/ZCS operation, and JEDEC-qualified reliability for industrial SMPS deployment.

Technical Context

This 900 V superjunction MOSFET employs CoolMOS™ C3 technology with optimized charge balancing for ultra-low R_DS(on) × Q_g figure-of-merit (0.5 Ω × 68 nC). Its 50 V/ns dv/dt rating enables robust operation in hard-switched and resonant converters without external snubbers.

The device integrates an intrinsic fast-recovery body diode (t_rr = 480 ns, Q_rr = 8.5 µC) and supports repetitive avalanche (E_AR, I_AR) with thermal resistance R_thJC = 0.8 K/W - critical for high-power density industrial SMPS designs requiring sustained peak current capability (I_D,pulse = 24 A).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	900 V - supports 400 V DC-link systems with ≥2× safety margin for surge and ringing
R_DS(on) max @ 25 °C	0.5 Ω - enables low conduction loss in 6–10 A continuous industrial SMPS stages
Q_g typ	68 nC - reduces gate drive power and enables high-frequency switching (>100 kHz) with minimal driver stress
E_AS single-pulse	388 mJ - withstands unclamped inductive switching events in flyback/forward converters
dv/dt ruggedness	50 V/ns - eliminates need for external dv/dt snubbers in high-speed switching applications
t_rr / Q_rr	480 ns / 8.5 µC - minimizes reverse recovery losses and EMI in synchronous rectification and LLC phases
R_thJC	0.8 K/W - allows direct heatsink mounting for thermally constrained industrial enclosures

Pinout & Package

PG-TO262 package: 3-pin through-hole, isolated heatsink tab (drain-connected), standard lead pitch compatible with TO-220 PCB footprints but with enhanced thermal performance.

Source	Power return and reference node	Low-inductance source path essential for stable gate control and minimizing shoot-through risk

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
IPW90R500C3FKSA1	Same R_DS(on) and Q_g, but in TO-247-3L package with higher R_thJC (0.95 K/W) and no isolated tab	Requires insulating washer for heatsink mounting; better suited for discrete heatsink assemblies than PCB-integrated thermal pads	Select when mechanical mounting flexibility outweighs thermal advantage of PG-TO262
STP90NF50	Higher R_DS(on) (0.6 Ω), higher Q_g (95 nC), no dv/dt rating specified, non-CoolMOS™ planar structure	Limited to <65 kHz operation due to higher switching losses; not qualified for repetitive avalanche	Only consider for cost-sensitive, low-frequency (<50 kHz), non-safety-critical consumer applications

Compared with IPW90R500C3FKSA1 and STP90NF50, the IPI90R500C3 offers superior thermal performance (0.8 K/W), integrated isolation, and guaranteed dv/dt ruggedness - making it the preferred choice for compact, high-reliability industrial and computing power supplies where board space and surge immunity are critical.

FAQ

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

The IPI90R500C3 supports 6.8 A continuous drain current at T_C = 100 °C, as specified in its absolute maximum ratings table. This rating assumes proper heatsinking and accounts for R_DS(on) increase with junction temperature - verified under JEDEC-standard test conditions with defined thermal interface resistance.

Does this MOSFET require a gate resistor, and what value is recommended?

Yes - a gate resistor is required to control turn-on/turn-off speed and suppress ringing. For typical 12 V gate drive and 6.6 A load, a 22–33 Ω series resistor is recommended based on gate charge (68 nC) and driver capability. Lower values increase switching speed but risk overshoot; higher values reduce EMI but raise switching losses.

Is the body diode suitable for synchronous rectification in a flyback converter?

No - the intrinsic body diode has t_rr = 480 ns and Q_rr = 8.5 µC, which causes significant reverse recovery loss and voltage spikes in high-frequency flyback operation. External Schottky or MOSFET-based synchronous rectifiers are required for efficiency above 65 kHz.

Can IPI90R500C3 replace older CoolMOS™ C2 devices in existing designs?

Yes - it is a direct drop-in replacement for IPI90R500C2XKSA2 in PG-TO262 packages, offering identical pinout, improved R_DS(on) (0.5 Ω vs. 0.55 Ω), lower Q_g (68 nC vs. 75 nC), and enhanced dv/dt ruggedness (50 V/ns vs. 40 V/ns), with no layout or drive circuit changes needed.
