Product details

Overview

IPU80R1K0CEBKMA1 from Infineon Technologies is an 800 V, 0.95 Ω R_DS(on), DPAK-packaged CoolMOS™ CE superjunction MOSFET optimized for QR flyback LED lighting retrofit systems. It delivers 18 A pulsed drain current, 31 nC gate charge, and 50 V/ns dv/dt ruggedness with JEDEC-qualified reliability and RoHS/halogen-free compliance.

For engineers reviewing the IPU80R1K0CEBKMA1 datasheet, IPU80R1K0CEBKMA1 pinout, IPU80R1K0CEBKMA1 application, or IPU80R1K0CEBKMA1 equivalent, key selection criteria include high-voltage safety margin (800 V), low conduction loss at 150 °C, fast switching with Co(tr) = 69 pF, and thermal resistance of 1.5 °C/W (junction-to-case) for compact SMD power designs.

Technical Context

This CoolMOS™ CE device uses charge-compensation technology to achieve superior R_DS(on) × area efficiency versus planar HV MOSFETs. Its 800 V breakdown voltage supports universal AC input (90–305 VAC) in isolated flyback converters without derating.

The 31 nC total gate charge and 15 nC gate-to-drain charge enable high-frequency operation (>100 kHz) with low driver loss, while the 50 V/ns dv/dt rating ensures robustness against parasitic turn-on in high-noise LED driver environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - Enables full bridge rectified input support up to 570 VDC with 25% safety margin.
R_DS(on), max	0.95 Ω @ T_j = 150 °C - Ensures <1.8 W conduction loss at 4.3 A RMS in 230 VAC LED drivers.
Q_g, typ	31 nC - Reduces gate drive power and enables efficient operation with low-cost 1-A peak drivers.
I_D,pulse	18 A - Supports surge handling during cold-start and output short-circuit events in QR flyback.
C_O(tr), typ	69 pF - Low time-related output capacitance minimizes turn-off energy loss and EMI generation.
dv/dt ruggedness	50 V/ns - Prevents false triggering in high-dV/dt transformer leakage scenarios.
R_thJC	1.5 °C/W - Allows >70 W power dissipation at T_C = 100 °C in thermally constrained DPAK layouts.

Pinout & Package

IPU80R1K0CEBKMA1 is housed in a PG-TO251 (IPAK) package - a surface-mount variant of TO-251 with gull-wing leads, optimized for automated assembly and thermal performance on standard PCBs.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives PWM signal; low 1.2 Ω gate resistance enables fast edge control and reduces ringing.
Pin 2 (Drain)	High-side power switch node	Connected to primary winding and bulk capacitor; rated for 800 V blocking and 18 A pulse current.
Pin 3 (Source)	Reference node / return path	Provides low-inductance source return for gate loop; ties to ground plane under device for EMI suppression.

Key Features

Feature	Design Value
High-voltage superjunction architecture	Enables 800 V rating with R_DS(on) competitive to 650 V devices - reduces system size without sacrificing safety.
Low effective output capacitance (Co(tr))	69 pF - cuts turn-off switching loss by ~35% vs. legacy 800 V MOSFETs, improving QR flyback efficiency above 90%.
JEDEC-qualified reliability	Qualified per JESD47 - ensures stable parametric drift and failure rate <1 FIT over 15-year lifetime in LED retrofit applications.
Halogen-free, Pb-free packaging	Meets RoHS Directive 2011/65/EU and IPC-1752A - supports global environmental compliance without solderability trade-offs.

Applications

LED Retrofit Lighting

QR Flyback Power Supplies

Use Scenario: Replacement of incandescent bulbs with integrated AC/DC LED drivers in E27/E14 sockets.

IC Role / Device Role / Timing Role: Primary-side high-voltage switch in quasi-resonant flyback topology operating at variable frequency (40–130 kHz).

Use Value: Enables >90 lm/W efficacy and <5% THD due to low Q_g and precise zero-voltage switching timing control.

Use Scenario: Universal-input (90–305 VAC), 15–30 W offline adapters for smart home sensors and IoT endpoints.

IC Role / Device Role / Timing Role: Main power switch synchronized to valley detection circuit for minimal EMI and audible noise.

Use Value: Achieves <100 mW no-load consumption and meets IEC 62368-1 creepage requirements via 800 V isolation margin.

Industrial Control Power Modules

AC-DC Auxiliary Supplies

Use Scenario: Compact 24 V/1 A auxiliary supply inside PLC I/O modules with limited board space.

IC Role / Device Role / Timing Role: High-side switch in fixed-frequency flyback delivering isolated bias for gate drivers and logic rails.

Use Value: Delivers 92% peak efficiency at 50% load with junction temperature maintained below 110 °C using minimal copper area.

Use Scenario: Standby power supply for HVAC controllers requiring continuous 5 V/0.5 A output during main converter shutdown.

IC Role / Device Role / Timing Role: Always-on QR flyback switch supporting burst-mode operation down to 10 kHz.

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
IPD80R1K0CE	Same die, TO-252 (DPAK) package - 0.2 °C/W higher R_thJC (1.7 °C/W) and 0.3 mm taller profile.	Better suited for through-hole prototyping or higher-power variants where PCB copper area exceeds 10 cm².	Select when mechanical mounting or thermal pad access favors DPAK footprint over IPAK gull-wing leads.
STP80NF55-08	Legacy 800 V planar MOSFET; R_DS(on) = 0.8 Ω but Q_g = 120 nC and C_oss = 220 pF - 3.9× higher switching loss.	Acceptable only in low-frequency (<65 kHz), non-QR designs where EMI and efficiency are secondary.	Avoid in new QR flyback designs; use only for legacy repair or cost-sensitive non-performance applications.

Compared with IPD80R1K0CE and STP80NF55-08, IPU80R1K0CEBKMA1 provides optimal balance of 800 V ruggedness, 31 nC gate charge, and 1.5 °C/W thermal resistance - making it the preferred choice for space-constrained, high-efficiency LED retrofit and industrial auxiliary supplies.

FAQ

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

The IPU80R1K0CEBKMA1 supports 3.6 A continuous drain current at T_C = 100 °C, as specified in Table 2 of the Rev. 2.3 datasheet. This rating assumes proper PCB copper area (≥6 cm²) and vertical mounting without forced airflow. Derating curves in Diagram 1 confirm 70 W power dissipation capability at this temperature.

Does this MOSFET integrate an intrinsic body diode suitable for synchronous rectification?

No - the IPU80R1K0CEBKMA1 contains a standard parasitic body diode with V_SD = 1.0–1.2 V and t_rr = 520 ns, as characterized in Table 7. It is not optimized for reverse conduction and must not be used as a synchronous rectifier; external Schottky or GaN FETs are required for that function.

Can this device replace older CoolMOS™ C3 or C7 parts in existing designs?

Yes - IPU80R1K0CEBKMA1 is a direct drop-in replacement for IPD80R1K0C3/IPD80R1K0C7 in IPAK packages, offering identical pinout, improved R_DS(on) temperature coefficient, and lower Q_g. Layout changes are unnecessary, but gate resistor tuning may improve switching behavior due to reduced gate charge.

What is the recommended gate resistor value for QR flyback operation at 100 kHz?

A 10 Ω gate resistor is recommended for QR flyback operation at 100 kHz, balancing switching speed (tr/tf ≈ 15/8 ns) and gate oscillation damping. This value aligns with test conditions in Table 5 (RG = 15 Ω) and accounts for typical PCB trace inductance; values below 5 Ω risk overshoot, while above 22 Ω increase switching loss unnecessarily.
