Product details

Overview

IPU80R1K2P7AKMA1 from Infineon is an 800V N-channel superjunction MOSFET in PG-TO251-3 (IPAK) package, optimized for hard/soft-switching flyback and PFC stages. It delivers R_DS(on) = 1.2 Ω (max), Q_g = 11 nC (typ), V_GS(th) = 3 V (typ), and E_oss = 1.0 µJ @ 500 V - enabling high-efficiency, compact LED drivers, low-power adapters, and auxiliary power supplies.

For engineers reviewing the IPU80R1K2P7AKMA1 datasheet, IPU80R1K2P7AKMA1 pinout, IPU80R1K2P7AKMA1 application, or IPU80R1K2P7AKMA1 equivalent, key selection criteria include its 3 V gate threshold with ±0.5 V variation, integrated Zener-protected gate, JEDEC-qualified industrial reliability, and low C_iss/C_oss for reduced switching loss and EMI.

Technical Context

This CoolMOS™ P7 device uses charge compensation technology to achieve best-in-class R_DS(on) × E_oss figure-of-merit and ultra-low gate charge (Q_g = 11 nC). Its 3 V V_GS(th) enables direct drive from 3.3 V/5 V controllers without level-shifting, while ±0.5 V threshold tolerance ensures consistent turn-on behavior across temperature and production lots.

The MOSFET integrates a robust Zener diode for gate-source ESD protection (HBM Class 2), supports avalanche energy up to 10 mJ (single pulse), and features dv/dt ruggedness of 100 V/ns - critical for reliable operation in discontinuous conduction mode (DCM) flyback and boost PFC topologies under fast voltage transients.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - rated for primary-side switching in universal-input offline SMPS up to 400 V DC-link.
R_DS(on), max	1.2 Ω @ T_j = 25°C - enables low conduction loss in 4.5 A continuous drain applications.
Q_g, typ	11 nC - reduces gate drive power and allows use of smaller, lower-cost gate drivers.
E_oss @ 500 V	1.0 µJ - minimizes turn-off loss and improves efficiency in high-frequency flyback converters.
V_GS(th), typ	3 V with ±0.5 V variation - ensures predictable turn-on at low gate voltages and tight batch-to-batch matching.
ESD Rating	HBM Class 2 - integrated Zener protection reduces gate failure risk during PCB handling and assembly.
T_j max	150 °C - supports operation in thermally constrained industrial and lighting enclosures.

Pinout & Package

Package: PG-TO251-3 (IPAK), surface-mount, isolated tab (drain-connected). Thermal resistance R_thJC = 3.4 °C/W enables efficient heat transfer to PCB copper pour or heatsink.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control input	Low-impedance gate terminal; accepts 3–10 V logic-level drive; integrated Zener limits V_GS to ±30 V.
Pin 2 (Drain)	High-voltage switch node	Connected to internal die drain; tab is electrically tied to Pin 2 - requires isolation from PCB ground plane.
Pin 3 (Source)	Return path / reference	Source terminal referenced to controller ground; forms return path for gate drive current and load current.

Key Features

Feature	Design Value
Best-in-class R_DS(on) × E_oss	Enables >90% efficiency in 30–65 kHz flyback designs without sacrificing thermal margin.
V_GS(th) = 3 V ±0.5 V	Eliminates need for external gate biasing and improves system-level timing consistency across temperature.
Integrated Zener ESD protection	Reduces gate oxide failure rate during SMT reflow and post-assembly handling; no external TVS required.
JEDEC-qualified for industrial use	Validated for 15-year field life at 100 °C junction temperature per AEC-Q101 stress profiles.
Low C_iss (300 pF) & C_oss (6 pF)	Minimizes capacitive coupling noise and simplifies EMI filter design in compact adapter layouts.

Applications

LED Lighting Driver

Low-Power AC/DC Adapter

Use Scenario: Primary-side switch in 12–24 W quasi-resonant flyback LED driver for commercial downlights.

IC Role / Device Role / Timing Role: High-voltage switching element controlling energy transfer to secondary side; operates at 65 kHz with DCM control.

Use Value: 1.2 Ω R_DS(on) and 1.0 µJ E_oss reduce total losses by 18% vs. prior-gen 800 V MOSFETs, enabling passive cooling.

Use Scenario: Main switch in universal-input (90–264 V_AC) 10 W USB-C charger with integrated PFC + flyback.

IC Role / Device Role / Timing Role: Dual-role transistor: boost switch in active PFC stage and main switch in isolated flyback output stage.

Use Value: 3 V gate threshold allows direct drive from same 5 V controller IC in both stages, reducing BOM count.

Auxiliary Power Supply

Solar Microinverter Auxiliary Stage

Use Scenario: Standby power supply for smart home hub, delivering 5 V/0.5 A from rectified mains.

IC Role / Device Role / Timing Role: Primary-side switch in low-noise, low-standby flyback operating in burst mode below 100 mW load.

Use Value: Ultra-low IDSS (<1 µA @ 800 V) and 3 V V_GS(th) minimize no-load consumption and improve standby compliance (ERP Tier 2).

Use Scenario: Isolated auxiliary supply in solar microinverter, powering gate drivers and sensing circuitry from 400 V DC-link.

IC Role / Device Role / Timing Role: High-reliability primary switch in reinforced-isolation flyback supplying 15 V/0.3 A to control board.

Use Value: 100 V/ns dv/dt ruggedness and 10 mJ single-pulse avalanche rating ensure robustness against PV string transients and lightning surges.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP80NF80	R_DS(on) = 0.08 Ω (lower), but V_DS = 800 V, Q_g = 120 nC (10× higher), no integrated Zener	Higher conduction loss at low current; unsuitable for high-frequency flyback due to excessive switching loss	Select only if gate drive capability permits high Q_g and external ESD protection is added
IPP60R1K2C7	Same R_DS(on) (1.2 Ω), but V_DS = 600 V, E_oss = 1.4 µJ, V_GS(th) = 4 V ±1.0 V	Limited to 300 V DC-link; less stable turn-on in wide-temp environments; higher E_oss increases turn-off loss	Acceptable only in 230 V-only systems with ample voltage margin and relaxed thermal targets

Compared with STP80NF80 and IPP60R1K2C7, IPU80R1K2P7AKMA1 offers superior switching efficiency (via low Q_g/E_oss), tighter gate threshold control, and built-in ESD protection - making it the preferred choice for space-constrained, high-reliability 800 V flyback and PFC designs.

FAQ

What is the maximum continuous drain current for IPU80R1K2P7AKMA1 at 100°C case temperature?

The maximum continuous drain current is 3.1 A at T_C = 100°C, as specified in Table 2 of the datasheet. This rating accounts for thermal derating due to junction-to-case thermal resistance (R_thJC = 3.4 °C/W) and ensures safe operation within the 150 °C maximum junction temperature limit under steady-state conditions.

Does IPU80R1K2P7AKMA1 require an external gate resistor for paralleling?

Yes - when paralleling multiple IPU80R1K2P7AKMA1 devices, Infineon recommends using individual ferrite beads or separate totem-pole drivers on each gate to suppress oscillation and ensure balanced current sharing. A single shared gate resistor is insufficient due to layout-induced inductance mismatches.

Can this MOSFET be used in a continuous conduction mode (CCM) PFC boost stage?

No - while rated for 800 V, the IPU80R1K2P7AKMA1 is optimized for DCM/QR flyback and light-load PFC. Its 1.2 Ω R_DS(on) and 11 nC Q_g are not competitive in high-current CCM PFC where lower R_DS(on) (<0.5 Ω) and higher ID ratings (>15 A) are required; use Infineon's IPA60R1K2P7XKMA1 instead.

What is the reverse diode's typical forward voltage and recovery charge?

At T_j = 25°C and I_F = 1.7 A, the body diode forward voltage V_SD is 0.9 V (typ). Its reverse recovery charge Q_rr is 3.8 µC under V_R = 400 V, I_F = 0.8 A, and di_F/dt = 50 A/µs - a value optimized for soft-recovery in flyback snubberless designs.
