Product details

Overview

IPU80R2K4P7AKMA1 from Infineon is an 800V superjunction N-channel CoolMOS™ P7 power MOSFET in PG-TO251-3 (IPAK) package, featuring R_DS(on) = 2.4 Ω (max), Q_g = 8 nC (typ), E_oss = 0.74 µJ at 500 V, V_GS(th) = 3 V (typ), and integrated Zener-protected gate. It serves as a high-voltage switching device in flyback converters for LED lighting, low-power adapters, and auxiliary power supplies.

For engineers reviewing the IPU80R2K4P7AKMA1 datasheet, IPU80R2K4P7AKMA1 pinout, IPU80R2K4P7AKMA1 application, or IPU80R2K4P7AKMA1 equivalent, key selection criteria include its 800 V V_DS, low gate charge for fast switching, tight ±0.5 V V_GS(th) tolerance, robust dv/dt ruggedness (100 V/ns), and JEDEC-qualified industrial reliability.

Technical Context

This MOSFET employs Infineon's 800 V CoolMOS™ P7 superjunction technology with optimized charge balance for reduced R_DS(on) × E_oss figure-of-merit and lower C_iss (150 pF) and C_oss (3.8 pF). Its 3 V gate threshold enables direct drive from 3.3 V/5 V controllers without level-shifting.

The device integrates a Zener diode for gate-source ESD protection (HBM Class 1C), supports hard and soft-switching topologies, and delivers 4 mJ single-pulse avalanche energy at T_j = 25 °C - critical for flyback snubberless operation and PFC stage stress resilience.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - supports full mains input range up to 400 V DC link with margin for surge and ringing in offline SMPS
R_DS(on), max	2.4 Ω at V_GS = 10 V, T_j = 25 °C - defines conduction loss in continuous current mode at rated ID
Q_g, typ	8 nC - enables efficient 100–300 kHz switching with low gate driver power and reduced switching loss
E_oss	0.74 µJ at 500 V - quantifies output capacitance energy loss during turn-on; directly impacts light-load efficiency
V_GS(th), typ	3 V with ±0.5 V variation - ensures consistent turn-on across temperature and process, simplifying gate drive design
dv/dt ruggedness	100 V/ns - withstands rapid voltage transients in high-side configurations without spurious turn-on
T_j max	150 °C - allows operation in sealed enclosures or high ambient environments without derating below 100 °C case temp

Pinout & Package

IPU80R2K4P7AKMA1 uses the PG-TO251-3 (IPAK) surface-mount package with exposed drain tab for thermal enhancement. The package features gull-wing leads and is RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control electrode	Receives gate drive signal; low Q_g and 3 V V_GS(th) allow compatibility with standard PWM ICs
Pin 2 (Drain)	High-voltage power terminal	Connected to drain node (e.g., transformer primary); electrically tied to exposed metal tab for heatsinking
Pin 3 (Source)	Reference and return path	Serves as local ground reference for gate drive and current sensing; low-inductance layout critical for EMI control

Key Features

Feature	Design Value
Best-in-class R_DS(on) × E_oss	Enables higher efficiency in 65–300 kHz flyback designs without compromising switching speed or thermal performance
Integrated Zener ESD protection	Eliminates need for external gate protection components, reducing BOM count and improving assembly yield
V_GS(th) = 3 V ±0.5 V	Minimizes gate drive uncertainty across temperature and lot variation, enabling reliable parallel operation
Fully JEDEC-qualified for industrial use	Validated for 150 °C operation and long-term reliability in uncontrolled ambient environments

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP80NF55-08	800 V, R_DS(on) = 0.08 Ω, Q_g = 120 nC - higher conduction loss but much higher current rating (55 A)	Designed for high-current linear/switching regulators, not optimized for low-power flyback efficiency	Select only when >10 A continuous ID is required; unsuitable for <5 W applications due to excessive gate drive demand
IPP65R280C7	650 V, R_DS(on) = 280 mΩ, Q_g = 24 nC - lower voltage rating, higher R_DS(on) × E_oss than P7 series	Targeted at 380 V DC bus systems; insufficient margin for 400 V+ PFC or universal-input flyback	Use only in 230 VAC-only or DC-fed systems where 650 V rating is sufficient; avoid in global-input designs

Compared with STP80NF55-08 and IPP65R280C7, IPU80R2K4P7AKMA1 offers superior light-load efficiency and gate drive simplicity for sub-5 W to 25 W offline converters, while maintaining industrial-grade ruggedness and tighter parametric distribution.

FAQ

What is the maximum continuous drain current for IPU80R2K4P7AKMA1 at 100°C case temperature?

The maximum continuous drain current is 1.7 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 resistance (5.6 °C/W) and ensures safe operation without exceeding 150 °C maximum junction temperature under steady-state conditions.

Does IPU80R2K4P7AKMA1 require an external gate resistor for stability in flyback applications?

Yes - while the device has low intrinsic gate resistance (4.0 Ω), a series gate resistor (typically 10–33 Ω) is recommended to dampen ringing, limit peak gate current, and prevent oscillation during fast switching. Infineon advises using ferrite beads on the gate line when paralleling multiple units to suppress common-mode noise.

Can IPU80R2K4P7AKMA1 be used in a totem-pole PFC configuration?

No - this 800 V CoolMOS™ P7 device is optimized for unidirectional hard/soft-switching topologies like flyback and boost PFC, not bidirectional totem-pole configurations. Totem-pole PFC requires symmetric body diode performance and reverse-conduction capability not provided by standard superjunction MOSFETs like this part.

What is the typical reverse recovery charge (Q_rr) of the integrated body diode?

The typical reverse recovery charge is 2.5 µC at V_R = 400 V, I_F = 0.41 A, and di_F/dt = 50 A/µs, per Table 7. This value reflects the stored charge in the body diode during commutation and contributes to switching loss in synchronous rectification or freewheeling paths.
