Product details

Overview

IPU60R1K4C6AKMA1 from Infineon Technologies is a 600 V, 1.4 Ω R_DS(on) CoolMOS™ C6 superjunction power MOSFET in PG-TO251 (IPAK) package, optimized for high-efficiency PFC and hard-switching SMPS stages. It delivers 9.4 nC gate charge, 1 µJ output energy at 400 V, and 500 A/µs body diode commutation capability, enabling compact, thermally efficient designs in server PSUs and telecom rectifiers.

For engineers reviewing the IPU60R1K4C6AKMA1 datasheet, IPU60R1K4C6AKMA1 pinout, IPU60R1K4C6AKMA1 application, or IPU60R1K4C6AKMA1 equivalent, key selection criteria include its 600 V V_DS, low E_oss-driven switching loss, industrial-grade JEDEC qualification, and IPAK drain-pin-down thermal layout compatibility.

Technical Context

This device implements Infineon's superjunction architecture with charge compensation trenches to achieve ultra-low R_DS(on) × Q_g figure-of-merit (FOM) of ~13.16 Ω·nC. Its gate threshold voltage (2.5–3.5 V) and plateau voltage (5.4 V) support robust 10 V gate drive while maintaining noise immunity in noisy power stage environments.

The integrated fast-recovery body diode exhibits 230 ns t_rr, 1.1 µC Q_rr, and 500 A/µs di/dt rating-enabling reliable operation in continuous conduction mode (CCM) PFC without external SiC diode supplementation. Thermal resistance R_thJC is 4.4 °C/W, optimized for PCB-mounted heatsinking via the exposed drain pad.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - supports 400 V AC input PFC stages with 50% safety margin against line surges
R_DS(on), max	1.4 Ω @ T_j = 25°C - enables <2.8 W conduction loss at 1.1 A RMS in 100 kHz PFC boost
Q_g, typ	9.4 nC - reduces gate driver power requirement and enables 300–500 kHz switching without excessive drive loss
E_oss @ 400 V	1 µJ - cuts turn-off energy by >60% vs. previous-gen SJ MOSFETs, lowering temperature rise in hard-switched converters
I_D,pulse	8 A - sustains short-term overload in UPS hold-up and server transient response
di/dt (body diode)	500 A/µs - ensures robust commutation in bridge-leg and synchronous rectifier configurations without oscillation
R_thJC	4.4 °C/W - allows 28.4 W continuous dissipation with ≤100°C junction rise over case at 25°C ambient

Pinout & Package

IPU60R1K4C6AKMA1 uses the PG-TO251 (IPAK) surface-mount package with an exposed drain pad on the bottom side for direct PCB thermal coupling. Pin 1 is Gate, Pin 2 is Drain (connected to exposed pad), and Pin 3 is Source - a drain-pin-down configuration ideal for low-inductance, high-current source return paths.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives 10 V logic-level drive; 14 Ω internal gate resistance limits ringing and simplifies RC snubber design
Pin 2 (Drain)	High-voltage power node	Internally connected to exposed copper pad; must be soldered to ≥6 cm² PCB copper area for thermal compliance
Pin 3 (Source)	Power return reference	Serves as local ground reference for gate driver; requires low-inductance Kelvin connection to minimize shoot-through risk

Key Features

Feature	Design Value
Superjunction FOM (R_DS(on) × Q_g)	13.16 Ω·nC - enables higher frequency operation without efficiency penalty in 80+ Gold PSUs
Body diode commutation ruggedness	500 A/µs di/dt rating - eliminates need for external anti-parallel diodes in LLC resonant half-bridges
JEDEC industrial qualification	Qualified per J-STD-020 (reflow) and JESD22-A108 (temperature cycling) - supports 10-year field reliability in telecom infrastructure
Low E_oss & high dv/dt immunity	1 µJ E_oss @ 400 V; 50 V/ns dv/dt rating - suppresses false turn-on in high-side configurations with minimal gate clamping

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
IPU60R1K0CEAKMA1	Lower R_DS(on) (1.0 Ω), higher Q_g (12.5 nC), same 600 V rating	Better conduction loss but higher switching loss above 250 kHz	Select when thermal budget is constrained and switching frequency ≤200 kHz
IPP60R1K4C6XKSA1	Same R_DS(on) and Q_g, TO-220 package instead of IPAK	Higher R_thJA (62 °C/W vs. 35 °C/W SMD), requires mechanical heatsink	Select when through-hole assembly or legacy board layout mandates TO-220 footprint

Compared with IPU60R1K4C6AKMA1, the IPU60R1K0CEAKMA1 trades gate charge for lower conduction loss-ideal for space-constrained PFC where thermal mass is limited. The IPP60R1K4C6XKSA1 offers identical electrical specs but demands mechanical heatsinking, making it suitable only where IPAK reflow constraints prohibit use.

FAQ

What is the maximum continuous drain current for IPU60R1K4C6AKMA1 at 100°C case temperature?

The maximum continuous drain current is 2.0 A at T_C = 100°C, as specified in Table 2 of the Rev. 2.0 datasheet. This limit is thermally derived from the 4.4 °C/W R_thJC and 150°C maximum junction temperature, ensuring safe operation under sustained load without exceeding thermal limits.

Does IPU60R1K4C6AKMA1 require a negative gate turn-off voltage?

No. The device is fully compatible with 0 V to +10 V gate drive and does not require negative turn-off bias. Its gate threshold voltage range (2.5–3.5 V) and 20 V maximum V_GS rating allow robust operation with standard unipolar drivers, eliminating need for level-shifters or dual-rail supplies.

How does the body diode performance compare to discrete silicon diodes in PFC applications?

The integrated body diode achieves 230 ns reverse recovery time and 1.1 µC Q_rr at 1.4 A, outperforming standard FRD diodes in softness and commutation speed. In CCM PFC, this enables zero-voltage switching (ZVS) assist and eliminates cross-conduction risk without external diode paralleling.

Is IPU60R1K4C6AKMA1 suitable for use in high-humidity industrial environments?

Yes. It is qualified to JEDEC J-STD-020 for moisture sensitivity level (MSL) 1 and undergoes 1000-hour HAST testing per JESD22-A110. The halogen-free mold compound and Pb-free plating provide corrosion resistance essential for humid factory-floor deployments.
