Product details

Overview

IPA80R280P7XKSA1 from Infineon is an 800V superjunction N-channel MOSFET in PG-TO220 FP package, featuring R_DS(on) = 0.28 Ω (max), Q_g = 36 nC (typ), V_GS(th) = 3 V (typ), integrated ESD protection (HBM Class 2), and optimized for hard/soft-switching flyback and PFC stages. It delivers high efficiency in LED lighting, low-power adapters, and industrial auxiliary supplies.

For engineers reviewing the IPA80R280P7XKSA1 datasheet, IPA80R280P7XKSA1 pinout, IPA80R280P7XKSA1 application, or IPA80R280P7XKSA1 equivalent, key selection criteria include 800V V_DS rating, low gate charge for fast switching, tight V_GS(th) tolerance (±0.5V), body diode recovery performance (Q_rr = 15 µC), and TO-220 FP thermal robustness (R_thJC = 4.1 °C/W).

Technical Context

This CoolMOS™ P7 device employs superjunction charge compensation architecture to achieve best-in-class figure-of-merit (R_DS(on) × E_oss) while maintaining rugged dv/dt immunity (100 V/ns) and avalanche capability (E_AS = 43 mJ). Its 3 V gate threshold enables direct drive from 3.3 V/5 V controllers without level-shifting.

The integrated Zener-protected gate structure reduces ESD-related failures during assembly, and its fully qualified JEDEC industrial rating ensures reliability across temperature (–55 to +150 °C) and power cycling. The TO-220 FP package features isolated drain pin (Pin 2) for simplified heatsinking and creepage-critical layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - Supports 400 V DC-link designs with ≥2× voltage margin for surge and ringing in flyback/PFC.
R_DS(on), max	0.28 Ω at T_j = 25°C - Enables <1.5 W conduction loss at 7.2 A, critical for thermally constrained adapters.
Q_g, typ	36 nC - Reduces gate driver power demand and switching transition time, lowering E_oss-related losses.
V_GS(th), typ	3 V with ±0.5 V variation - Ensures consistent turn-on across temperature and process, simplifying gate drive design.
E_oss @ 500 V	4 µJ - Low output energy enables efficient soft-switching operation and reduces snubber losses.
Q_rr	15 µC - Predictable reverse recovery supports stable operation in discontinuous conduction mode (DCM) flyback.
R_thJC	4.1 °C/W - Allows >25 W continuous dissipation with moderate heatsinking, suitable for compact industrial AUX rails.

Pinout & Package

Package: PG-TO220 FP (FullPAK), through-hole, isolated drain tab, RoHS-compliant, lead-free plating.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Low-impedance input accepting 0–20 V logic-level signals; internal Zener clamps transients to protect gate oxide.
Pin 2 (Drain)	High-voltage power terminal	Electrically isolated metal tab; connects directly to PCB heatsink or chassis ground for thermal and safety isolation.
Pin 3 (Source)	Power return and reference node	Serves as local ground reference for gate drive; carries full load current and reverse diode conduction current (I_S = 7 A).

Key Features

Feature	Design Value
Best-in-class R_DS(on) × E_oss	Enables higher switching frequencies without sacrificing conduction loss-ideal for compact 65–100 kHz flyback designs.
Integrated ESD protection (HBM Class 2)	Eliminates need for external gate protection components, reducing BOM count and improving manufacturing yield.
Tight V_GS(th) distribution (±0.5 V)	Minimizes unit-to-unit variation in turn-on timing, enabling reliable paralleling without gate resistors or ferrite beads.
Fully JEDEC-qualified for industrial use	Validated for 150 °C operation and extended temperature cycling-supports 10+ year field life in industrial power supplies.
Optimized body diode (Q_rr = 15 µC, t_rr = 1200 ns)	Reduces voltage overshoot and EMI in DCM flyback, especially when used in self-oscillating or QR controllers.

Applications

LED Lighting Power Supply

USB-C Adapter Secondary Side

Use Scenario: 40 W isolated flyback converter powering smart LED drivers in commercial fixtures.

IC Role / Device Role / Timing Role: Primary-side high-voltage switch operating at 65 kHz with quasi-resonant control.

Use Value: Low R_DS(on) and E_oss reduce no-load consumption below 75 mW and improve full-load efficiency to >90%.

Use Scenario: 30 W USB PD adapter with active clamp flyback topology and 3.3 V/5 V synchronous rectification.

IC Role / Device Role / Timing Role: Main power switch handling 400 V DC-link with 100 kHz switching and valley switching detection.

Use Value: Tight V_GS(th) tolerance ensures consistent zero-voltage switching (ZVS) initiation across line/load conditions.

Industrial Auxiliary Power

Solar Microinverter PFC Stage

Use Scenario: 15 W 24 V auxiliary supply for PLC I/O modules operating in –40 to +85 °C ambient.

IC Role / Device Role / Timing Role: Hard-switched flyback switch with fixed-frequency PWM control and overtemperature shutdown.

Use Value: JEDEC industrial qualification and R_thJC = 4.1 °C/W allow derating-free operation up to 85 °C case temperature.

Use Scenario: Boost PFC front-end in 300 W microinverter, rectifying 350–450 V DC from PV string.

IC Role / Device Role / Timing Role: Continuous conduction mode (CCM) boost switch operating at 65 kHz with average current mode control.

Use Value: Low Q_g and C_iss (1200 pF) minimize gate drive losses and enable single-stage gate driver IC integration.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 800V superjunction MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP80NF80	R_DS(on) = 0.3 Ω (max), Q_g = 120 nC, no integrated ESD diode, V_GS(th) = 2–4 V (±1 V)	Higher switching losses due to 3.3× larger Q_g; requires external gate protection and tighter layout for EMI control.	Preferred only where legacy design reuse or cost sensitivity outweighs efficiency and robustness requirements.
IPP80R280P7	Same die, identical specs, but in PG-TO220 (non-FP) package with non-isolated drain tab	Lacks creepage/clearance advantage of FP variant; requires insulating pad or slotting for reinforced isolation in safety-critical designs.	Select only when mechanical mounting constraints preclude FP's isolated tab or when lower-cost standard TO-220 suffices.

Compared with STP80NF80 and IPP80R280P7, IPA80R280P7XKSA1 uniquely combines isolated drain packaging, industry-leading R_DS(on) × E_oss, and ±0.5 V V_GS(th) tolerance-enabling smaller heatsinks, simpler gate drive, and safer high-voltage layout in space-constrained industrial and consumer power supplies.

FAQ

Is IPA80R280P7XKSA1 suitable for paralleling in high-current designs?

Yes-its tight V_GS(th) tolerance (±0.5 V) and low R_DS(on) temperature coefficient enable stable current sharing without gate ferrite beads in most cases. For >30 A total current, use matched gate resistors (≤2.2 Ω) and symmetrical PCB routing to minimize loop inductance imbalance.

What is the maximum recommended gate resistor value for 65 kHz flyback operation?

A 10 Ω gate resistor provides optimal trade-off between switching speed (t_r/t_f ≈ 6/5 ns) and EMI suppression at 65 kHz. Values above 22 Ω increase switching losses significantly; values below 4.7 Ω require careful layout to avoid gate oscillation due to low Q_g (36 nC) and high dv/dt (100 V/ns).

Does the integrated ESD diode affect gate drive behavior?

No-the integrated Zener diode clamps only during ESD events (>2 kV HBM); it does not conduct during normal operation (V_GS ≤ 20 V). Gate drive waveforms remain unaffected, and no additional gate capacitance is introduced beyond the specified C_iss (1200 pF).

Can IPA80R280P7XKSA1 replace older CoolMOS™ P6 devices in existing designs?

Yes-pin-compatible with IPA80R280P6XKSA1 and offers 15% lower R_DS(on) × E_oss, reduced Q_g, and tighter V_GS(th). No layout changes needed; gate drive voltage and snubber values remain valid, though efficiency gains may allow downsizing heatsinks by ~20%.
