Product details

Overview

IPU60R1K4C6BKMA1 from Infineon Technologies is a 600 V, 1.4 Ω R_DS(on) CoolMOS™ C6 superjunction N-channel power MOSFET in PG-TO251 (IPAK) package, optimized for high-efficiency PFC and hard-switching SMPS in industrial power supplies. It delivers 9.4 nC total gate charge, 1 µJ output energy at 400 V, and 500 A/µs body diode di/dt capability.

For engineers reviewing the IPU60R1K4C6BKMA1 datasheet, IPU60R1K4C6BKMA1 pinout, IPU60R1K4C6BKMA1 application, or IPU60R1K4C6BKMA1 equivalent, key selection criteria include its 600 V V_DS, low R_DS(on) × Q_g figure-of-merit, high commutation ruggedness, and JEDEC industrial-grade qualification.

Technical Context

This CoolMOS™ C6 device implements a superjunction structure enabling simultaneous reduction of conduction and switching losses. Its 1.4 Ω R_DS(on) at 10 V V_GS and 9.4 nC Q_g support high-frequency operation up to 100 kHz in continuous conduction mode PFC stages.

The MOSFET features a 5.4 V gate plateau voltage and 11 pF energy-related output capacitance (C_oss,eff), ensuring predictable turn-off behavior under 400 V bus conditions. Its 500 A/µs body diode di/dt rating enables robust operation in resonant topologies without external snubbing.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - supports 400 V AC input PFC designs with 20% margin for line surges
R_DS(on), max	1.4 Ω at T_j = 25°C - enables <2.8 W conduction loss at 1.1 A DC current
Q_g, typ	9.4 nC - reduces gate drive power requirement in 65–100 kHz SMPS
E_oss @ 400 V	1 µJ - minimizes turn-off switching loss in hard-switched converters
Body diode di/dt	500 A/µs - sustains fast reverse recovery in LLC and phase-shifted full-bridge topologies
P_D @ T_C = 25°C	28.4 W - requires minimal heatsinking in IPAK-mounted industrial adapters
R_thJC	4.4 °C/W - enables direct thermal coupling to PCB copper pour or small metal heatsink

Pinout & Package

IPU60R1K4C6BKMA1 uses the PG-TO251 (IPAK) surface-mount package with exposed drain pad for thermal performance. Pin 1 is Gate, Pin 2 is Drain, Pin 3 is Source - standard configuration for single-ended TO-251 footprint compatibility.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives 10 V logic-level drive; 14 Ω gate resistance simplifies RC snubber design
Pin 2 (Drain)	High-voltage power output	Connected to primary-side HV rail; exposed pad provides low-inductance thermal path
Pin 3 (Source)	Power return / reference node	Serves as local ground for gate driver; ties to source of synchronous rectifier in secondary side

Key Features

Feature	Design Value

High commutation ruggedness	26 mJ single-pulse avalanche energy - withstands transient overvoltage during startup or fault conditions
Easy gate drive	5.4 V gate plateau voltage - ensures stable Miller region control with standard 12 V gate drivers
Industrial qualification	JEDEC J-STD-020 & JESD22 compliant - guaranteed operation from –55°C to +150°C junction temperature
Pb-free & halogen-free	RoHS-compliant plating and mold compound - meets IPC-J-STD-609A Class 1 requirements

Applications

IC Role / Device Role / Timing Role: Primary-side high-voltage switch handling 400 V DC bus and 100 kHz switching.

Use Value: 1 µJ E_oss reduces turn-off loss by 35% vs. previous-generation SJ MOSFETs at same R_DS(on).

Use Scenario: Boost PFC stage in -48 V telecom system with universal AC input (90–264 VAC).

IC Role / Device Role / Timing Role: Critical conduction mode (CRM) or continuous conduction mode (CCM) switch.

Use Value: 500 A/µs di/dt rating prevents diode failure during zero-current switching transitions.

LCD TV Power Board

Industrial UPS Inverter

Use Scenario: Main SMPS in 42–65 inch LCD TV power board operating at 70 kHz with 380 V DC bus.

IC Role / Device Role / Timing Role: High-side switch in half-bridge topology driving flyback or forward transformer.

Use Value: 4.4 °C/W R_thJC allows direct PCB copper cooling-eliminates need for discrete heatsink.

Use Scenario: Output H-bridge in 3 kVA industrial UPS delivering pure sine wave to critical loads.

Use Value: 1.4 Ω R_DS(on) limits conduction loss to <1.5 W per device at 2.5 A RMS load current.

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
IPU60R1K0P6	Lower R_DS(on) (1.0 Ω), higher Q_g (12.5 nC), same 600 V rating	Better conduction loss but increased gate drive loss above 80 kHz	Select when thermal budget is constrained and switching frequency ≤65 kHz
IPP60R1K4C6	Same R_DS(on) and Q_g	TO-220 package - higher R_thJA (62 °C/W vs. 35 °C/W for IPAK on PCB)	Select when through-hole mounting or legacy footprint compatibility is required

Compared with IPU60R1K4C6BKMA1, the IPU60R1K0P6 trades higher gate charge for lower conduction loss, while the IPP60R1K4C6 maintains identical electrical specs but sacrifices thermal performance due to larger package thermal resistance.

FAQ

What is the maximum continuous drain current for IPU60R1K4C6BKMA1 at 100°C case temperature?

The maximum continuous drain current is 2.0 A at T_C = 100°C, derated from 3.2 A at 25°C case temperature per the datasheet's maximum ratings table. This limit is thermally defined by junction temperature constraints and assumes proper PCB copper area for heat dissipation.

Does IPU60R1K4C6BKMA1 require a negative gate voltage for reliable turn-off?

No. The device operates reliably with 0 V to 10 V gate drive; its gate threshold voltage range is 2.5–3.5 V, and it is fully enhanced at V_GS = 10 V. A negative gate bias is not required, though –5 V may be used to improve noise immunity in high-dV/dt environments.

Can IPU60R1K4C6BKMA1 replace older CoolMOS™ C3 devices in existing designs?

Yes - it is a direct drop-in replacement for IPU60R1K4C3 in most cases, offering lower R_DS(on) × Q_g, improved E_oss, and higher di/dt capability. Layout changes are unnecessary, but gate resistor values may be optimized to match the reduced Q_g and faster switching.

What is the recommended PCB layout practice for thermal management of the IPAK package?

Use ≥6 cm² of 70 µm thick copper on the drain pad layer, connected via ≥6 thermal vias (0.3 mm diameter) to inner or backside ground planes. Maintain vertical board orientation without forced airflow, as specified in the thermal characteristics section for R_thJA = 35 °C/W.
