Product details

Overview

IPU80R1K4P7AKMA1 from Infineon is an 800V CoolMOS™ P7 superjunction N-channel power MOSFET in PG-TO251 (IPAK) package, featuring R_DS(on) = 1.4 Ω (max), Q_g = 10 nC (typ), V_GS(th) = 3 V (typ), and integrated Zener ESD protection. It delivers high-voltage switching for flyback converters in LED lighting, low-power adapters, and auxiliary power supplies.

For engineers reviewing the IPU80R1K4P7AKMA1 datasheet, IPU80R1K4P7AKMA1 pinout, IPU80R1K4P7AKMA1 application, or IPU80R1K4P7AKMA1 equivalent, key selection criteria include its 800V V_DS, low 1.4 Ω on-resistance at 10 V_GS, 3 V gate threshold with ±0.5 V variation, 0.9 µJ E_oss at 500 V, and industrial-grade JEDEC qualification.

Technical Context

This MOSFET employs Infineon's 800V CoolMOS™ P7 superjunction technology optimized for hard- and soft-switching flyback topologies. Its 3 V V_GS(th) enables direct drive from 3.3 V/5 V controllers, while low C_iss (250 pF) and C_oss (6.5 pF) reduce switching losses and improve EMI behavior.

The device integrates a Zener-protected gate structure rated for HBM Class 2 ESD, and features robust dv/dt ruggedness (100 V/ns) and avalanche capability (8 mJ single-pulse). Thermal resistance R_thJC is 3.9 °C/W, supporting high-power-density thermal management in compact SMD layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - supports primary-side switching in universal-input offline SMPS up to 400 V DC link
R_DS(on), max	1.4 Ω @ V_GS = 10 V, T_j = 25°C - enables <4 W conduction loss at 2 A ID in 25°C ambient
Q_g, typ	10 nC - allows efficient gate driving with standard 1–2 A peak gate drivers
E_oss @ 500 V	0.9 µJ - reduces turn-off energy loss and improves light-load efficiency in flyback converters
V_GS(th), typ	3 V with ±0.5 V variation - ensures reliable turn-on across temperature and process corners using 3.3 V logic
ESD Rating (HBM)	Class 2 - provides built-in gate protection against handling-induced electrostatic discharge
R_thJC	3.9 °C/W - enables 32 W power dissipation with ≤125°C junction rise over case at 25°C ambient

Pinout & Package

IPU80R1K4P7AKMA1 uses the PG-TO251 (IPAK) surface-mount package with exposed drain tab for thermal enhancement. The package has three leads and is RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives gate drive signal; low 1.5 Ω internal gate resistance simplifies driver design
Pin 2 (Drain) + Tab	High-voltage power terminal	Tab is electrically connected to drain; serves as primary thermal path to PCB copper pour
Pin 3 (Source)	Reference and current return	Provides source connection for gate drive loop and current sensing; low-inductance layout critical for EMI

Key Features

Feature	Design Value
Best-in-class R_DS(on) × E_oss FOM	Enables higher efficiency and lower heat generation than prior 800 V SJ MOSFETs in flyback designs
V_GS(th) = 3 V ± 0.5 V	Reduces risk of partial turn-on during startup or noise transients; improves system reliability
Integrated Zener ESD protection	Eliminates need for external gate protection components, lowering BOM count and assembly cost
JEDEC industrial qualification	Validated for continuous operation at T_j = 150°C per J-STD-20/JESD22, supporting long-life industrial deployments

Applications

LED Lighting Drivers

Low-Power AC/DC Adapters

Use Scenario: Constant-voltage or constant-current isolated flyback converters powering commercial LED luminaires.

IC Role / Device Role / Timing Role: Primary-side high-voltage switch regulating output via optocoupler feedback or primary-side sensing.

Use Value: Low R_DS(on) and E_oss enable >88% efficiency at 12 W with minimal heatsinking and reduced transformer size.

Use Scenario: Universal-input (90–264 VAC) 5–20 W wall adapters for consumer electronics.

IC Role / Device Role / Timing Role: Main power switch in discontinuous conduction mode (DCM) flyback topology.

Use Value: 3 V gate threshold allows direct drive from low-voltage PWM controllers, reducing gate driver complexity and cost.

Auxiliary Power Supplies

PFC Stage in Consumer Electronics

Use Scenario: Standby or bias supply in multi-rail systems (e.g., TV mainboard, industrial PLC).

IC Role / Device Role / Timing Role: High-voltage switch in self-oscillating or fixed-frequency flyback providing isolated 5–12 V bias rails.

Use Value: Robust dv/dt rating (100 V/ns) prevents false triggering during high-noise start-up and load transients.

Use Scenario: Interleaved or single-stage boost PFC in sub-100 W consumer appliances (e.g., air purifiers, smart speakers).

IC Role / Device Role / Timing Role: Switching element in continuous conduction mode (CCM) boost converter operating at 65–100 kHz.

Use Value: Low Q_g and C_iss minimize gate drive loss and improve power factor correction linearity under varying loads.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPU80R1K0P7AKMA1	R_DS(on) = 1.0 Ω (max), same 800 V rating and P7 platform	Higher conduction loss margin required; better suited for <10 W ultra-compact adapters	Select when lower on-resistance justifies slightly higher cost and identical footprint compatibility
IPU80R1K4CEAKMA1	Same R_DS(on) but CoolMOS™ CE variant; higher Q_g (12 nC) and no integrated Zener	Lacks built-in ESD protection; requires external gate clamp diode	Choose only if legacy CE design reuse is needed and gate protection is already implemented externally

Compared with IPU80R1K4P7AKMA1, the P7-based IPU80R1K0P7 offers lower conduction loss at identical voltage rating, while the CE variant trades ESD robustness and gate charge for marginal cost reduction-neither matches the P7's combined performance, ease-of-use, and reliability profile.

FAQ

What is the maximum continuous drain current for IPU80R1K4P7AKMA1 at 100°C case temperature?

The maximum continuous drain current is 2.7 A at T_C = 100°C, as specified in Table 2 of the datasheet. This derating reflects thermal limits of the PG-TO251 package and ensures safe operation within the SOA boundary at elevated temperatures without exceeding T_j = 150°C.

Does IPU80R1K4P7AKMA1 require an external gate resistor for stability in flyback applications?

Yes-while the device has low intrinsic gate resistance (1.5 Ω), a discrete gate resistor (typically 10–47 Ω) is recommended to dampen ringing, control dV/dt, and prevent oscillation during hard switching. Infineon's application notes further advise ferrite beads on parallel-configured gates to suppress common-mode noise.

How does the integrated Zener diode protect the gate, and what is its clamping voltage?

The integrated Zener diode clamps gate-to-source voltage to approximately ±20 V, protecting against overvoltage transients during handling or circuit faults. It is rated for HBM Class 2 (≥2 kV), eliminating the need for external TVS diodes in most board-level ESD environments per IEC 61000-4-2 Level 2.

Can IPU80R1K4P7AKMA1 be used in PFC boost stages, and what is its maximum recommended switching frequency?

Yes-it is qualified for PFC stages in consumer applications, with typical use up to 100 kHz in CCM boost. Its low E_oss (0.9 µJ) and Q_g (10 nC) support efficient operation at this frequency; however, thermal design must account for R_DS(on) increase with temperature, especially above 85°C ambient.
