Product details

Overview

IPI11N60C3AAKSA2 from Infineon Technologies is a 600 V, 11 A, N-channel CoolMOS™ C3 power MOSFET in I2PAK (TO-262) package, optimized for high-efficiency SMPS in server PSUs and industrial AC-DC converters. It features 450 mΩ R_DS(on), 17 nC total gate charge, and 100% avalanche-rated ruggedness.

For engineers reviewing the IPI11N60C3AAKSA2 datasheet, IPI11N60C3AAKSA2 pinout, IPI11N60C3AAKSA2 application, or IPI11N60C3AAKSA2 equivalent, key selection criteria include R_DS(on), E_oss, gate charge, avalanche capability, and thermal resistance in TO-262 mounting configurations.

Technical Context

This device implements Infineon's 3rd-generation superjunction technology with field-proven charge compensation structure, enabling low conduction and switching losses simultaneously. Its optimized cell layout reduces gate-drain charge (Q_gd) to 5.8 nC and output capacitance (C_oss) to 190 pF at V_DS = 25 V.

The MOSFET supports hard-switched topologies including flyback, forward, and LLC resonant converters up to 100 kHz. Its 100% UIS-tested ruggedness ensures reliable operation under transient overvoltage and short-circuit conditions without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - Withstands DC bus voltages up to 400 VAC rectified systems with margin.
I_D (T_C = 25°C)	11 A - Continuous drain current rating at case temperature, defining thermal design headroom.
R_DS(on) max	450 mΩ - Conduction loss contributor; determines on-state power dissipation at rated current.
Q_g total	17 nC - Gate drive energy requirement; impacts driver IC selection and switching loss trade-off.
E_oss	1.2 µJ @ 400 V - Output stored energy affecting turn-on loss and ZVS feasibility in resonant designs.
R_thJC	1.2 K/W - Junction-to-case thermal resistance; defines heatsink interface requirements for 11 A operation.

Pinout & Package

Package: I2PAK (TO-262), surface-mount with isolated tab, 3-pin configuration. Tab is electrically connected to drain for direct heatsinking.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Reference node for gate drive and current return path; connects to PCB ground plane.
Pin 2 (Gate)	Control input	High-impedance MOS gate requiring <1 µA bias; sensitive to ESD and ringing.
Pin 3 (Drain / Tab)	Power output / Heat sink interface	Carries full load current and dissipates heat; must be soldered to copper pour or heatsink.

Key Features

Feature	Design Value
Optimized Q_g/R_DS(on) ratio	1.54 nC/Ω - Enables lower gate drive loss while maintaining conduction efficiency in 65–100 kHz SMPS.
100% UIS tested	Rated for 100% unclamped inductive switching - eliminates need for external clamping circuits in flyback/forward designs.
Low E_oss	1.2 µJ @ 400 V - Reduces turn-on switching loss and improves ZVS initiation in LLC half-bridge topologies.
Enhanced dV/dt ruggedness	4.5 kV/µs - Resists false triggering during fast voltage transients in high-noise industrial environments.

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
STP12N60DM6	R_DS(on) = 480 mΩ, Q_g = 19.5 nC, no UIS rating	Lacks 100% UIS test; requires external clamping in inductive loads	Prefer for cost-sensitive non-UIS-critical PFC stages where gate drive loss is secondary
IPP60R190C7	R_DS(on) = 190 mΩ, Q_g = 29 nC, 650 V rating	Lower R_DS(on) but higher Q_g; larger die area increases capacitance-related losses above 70 kHz	Prefer for <60 kHz hard-switched applications needing lower conduction loss at expense of switching loss

Compared with STP12N60DM6 and IPP60R190C7, the IPI11N60C3AAKSA2 delivers optimal balance of R_DS(on), Q_g, and ruggedness for 65–100 kHz server and industrial SMPS, where UIS reliability and gate drive efficiency are jointly critical.

FAQ

What is the maximum junction temperature for continuous operation?

The IPI11N60C3AAKSA2 has a maximum rated junction temperature of 150 °C. Derating is required above T_C = 25 °C per the R_thJC = 1.2 K/W specification; full 11 A current is only sustainable with case temperature maintained ≤100 °C via adequate heatsinking.

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

No. The IPI11N60C3AAKSA2 is designed for 0 V to +15 V gate drive. A negative turn-off voltage is not required or recommended; its enhanced dV/dt immunity (4.5 kV/µs) prevents spurious turn-on without negative biasing.

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

Yes - the IPI11N60C3AAKSA2 is pin-compatible and electrically backward-compatible with IPI11N60C2, offering lower R_DS(on) (450 mΩ vs. 480 mΩ) and improved E_oss, enabling efficiency gains without layout changes in most 600 V SMPS designs.

Is the I2PAK package lead-free and RoHS-compliant?

Yes. The IPI11N60C3AAKSA2 uses lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with halogen-free molding compound per IEC 61249-2-21.
