Product details

Overview

IPD65R1K5CEAUMA1 from Infineon Technologies is a 650 V, 1.5 Ω R_DS(on) CoolMOS™ CE superjunction power MOSFET in DPAK (PG-TO252) package, optimized for cost-sensitive PFC and hard-switching SMPS stages in lighting and adapter applications. It delivers 5.2 A continuous drain current at T_C = 25°C, 10.5 nC total gate charge, and 1.15 µJ output switching energy at 400 V.

For engineers reviewing the IPD65R1K5CEAUMA1 datasheet, IPD65R1K5CEAUMA1 pinout, IPD65R1K5CEAUMA1 application, or IPD65R1K5CEAUMA1 equivalent, key selection criteria include its 700 V V_DS rating at T_j,max, high commutation ruggedness (500 A/µs di/dt), low FOM (R_DS(on) × Q_g), and gate drive simplicity with 5.4 V plateau voltage.

Technical Context

This CoolMOS™ CE device implements a superjunction structure enabling high-voltage blocking with reduced on-resistance and switching losses. Its dynamic parameters-10.5 nC Q_g, 5.8 nC Q_gd, and 1.15 µJ E_oss at 400 V-are calibrated for high-efficiency 65–100 kHz PFC and resonant converters.

The MOSFET features robust unclamped inductive switching capability (26 mJ E_AS) and reverse diode performance with 200 ns t_rr, 0.9 µC Q_rr, and 8 A I_rrm, supporting reliable operation in both high-side and low-side configurations without external snubbers in many designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	650 V - Rated blocking voltage for universal-input offline PFC and SMPS primary switches
R_DS(on) max	1.50 Ω @ T_j = 150°C - Enables thermally stable conduction loss in compact heatsink designs
I_D cont	5.2 A @ T_C = 25°C - Supports up to ~60 W continuous output in non-isolated flyback or boost topologies
Q_g typ	10.5 nC - Low gate drive power requirement compatible with standard PWM controllers (e.g., ICE2QS03)
E_oss	1.15 µJ @ 400 V - Reduces turn-on loss in ZVS/ZCS resonant stages and improves light-load efficiency
t_r/t_f	5.9 ns / 18.2 ns - Fast switching enables high-frequency operation while maintaining EMI control via adjustable gate resistance
di/dt ruggedness	500 A/µs - Sustains fast current transients during hard-switched transitions without oscillation or failure

Pinout & Package

Package: PG-TO252 (DPAK), surface-mount, single-drain-tab configuration with exposed drain pad for thermal enhancement.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control input	Accepts standard 10–13 V logic-level gate drive; 6.5 Ω internal gate resistance simplifies layout
Pin 2 (Drain) + Tab	High-voltage power terminal	Exposed copper tab electrically connected to drain; requires isolation from heatsink or use of insulating pad
Pin 3 (Source)	Reference node	Serves as return path for gate drive and load current; connects directly to PCB ground plane for low-inductance routing

Key Features

Feature	Design Value
Superjunction architecture	Enables 650 V rating with 1.5 Ω R_DS(on), reducing conduction loss by >30% vs. planar MOSFETs at same die size
Low R_DS(on) × Q_g figure-of-merit	15.75 Ω·nC - Optimizes trade-off between switching and conduction loss for 65–100 kHz operation
High commutation ruggedness	Rated for 500 A/µs di/dt and 50 V/ns dv/dt - Eliminates need for gate clamping in most PFC boost circuits
Pb-free & halogen-free construction	Complies with RoHS 2011/65/EU and JEDEC J-STD-020 reflow profile - Suitable for lead-free assembly in consumer lighting

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
IPP65R1K5C7	Same R_DS(on) (1.5 Ω), but TO-220FP package; higher R_thJA (62 vs. 50 °C/W); 11.5 nC Q_g	Requires through-hole assembly and larger heatsink; less suitable for ultra-thin lighting enclosures	Select when board space permits larger footprint and higher thermal mass is acceptable
IPD65R1K5CFD	Includes integrated fast-recovery body diode (t_rr = 120 ns vs. 200 ns); identical R_DS(on), Q_g, and package	Better suited for synchronous rectification or bidirectional topologies requiring lower Q_rr	Select when diode reverse recovery performance is critical, e.g., in high-frequency LLC or active clamp forward

Compared with IPP65R1K5C7 and IPD65R1K5CFD, IPD65R1K5CEAUMA1 offers the lowest system cost in surface-mount lighting and adapter designs where DPAK footprint and standard diode performance are sufficient, balancing efficiency, layout simplicity, and procurement availability.

FAQ

What is the maximum junction temperature rating for IPD65R1K5CEAUMA1?

The absolute maximum operating junction temperature is 150°C, with derated continuous drain current of 3.3 A at T_C = 100°C. Thermal resistance from junction to case is 2.37°C/W, enabling reliable operation with modest heatsinking in enclosed lighting fixtures.

Does IPD65R1K5CEAUMA1 require a gate resistor for stability?

Yes - a 10.2 Ω gate resistor is specified in the datasheet test conditions for switching characterization. While the device has internal 6.5 Ω gate resistance, an external series resistor (typically 5–22 Ω) is recommended to dampen ringing, control dV/dt, and ensure clean turn-on/turn-off in hard-switched topologies.

Can IPD65R1K5CEAUMA1 be used in parallel configurations?

Yes, but with design precautions: gate ferrite beads or individual totem-pole drivers are recommended per device to prevent current imbalance. The datasheet notes that paralleling requires matched PCB layout, thermal coupling, and gate drive symmetry to avoid thermal runaway under high-current conditions.

Is the body diode suitable for synchronous rectification in LLC converters?

No - the body diode has 200 ns reverse recovery time and 0.9 µC Q_rr, making it unsuitable for high-frequency synchronous rectification. For such applications, Infineon recommends the IPD65R1K5CFD variant with optimized diode or discrete SiC/Schottky co-packaging.
