Product details

Overview

IPP80R450P7XKSA1 from Infineon is an 800V superjunction N-channel MOSFET in PG-TO220-3 package, optimized for hard/soft-switching flyback and PFC stages. It delivers R_DS(on) = 0.45 Ω (max), Q_g = 24 nC (typ), V_GS(th) = 3 V (typ), and integrated Zener ESD protection. Used in LED lighting drivers, low-power adapters, and auxiliary power supplies.

For engineers reviewing the IPP80R450P7XKSA1 datasheet, IPP80R450P7XKSA1 pinout, IPP80R450P7XKSA1 application, or IPP80R450P7XKSA1 equivalent, key selection criteria include 800V V_DS rating, low gate charge for high-frequency switching, tight V_GS(th) tolerance (±0.5V), and industrial-grade JEDEC qualification.

Technical Context

This CoolMOS™ P7 device employs superjunction architecture to minimize conduction and switching losses simultaneously. Its 0.45 Ω R_DS(on) at 10 V_GS and 24 nC total gate charge enable high-efficiency operation up to 100 kHz in flyback converters.

The MOSFET integrates a robust Zener-protected gate with 2 kV HBM ESD rating and features a 3 V threshold voltage with ±0.5 V variation-enabling reliable turn-on across temperature and simplifying gate driver design without overdrive.

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	0.45 Ω - enables 11 A continuous drain current at T_C = 25°C with <1.7 °C/W thermal resistance.
Q_g, typ	24 nC - reduces gate drive power loss and allows use of low-cost, low-current gate drivers.
V_GS(th), typ	3 V - ensures clean turn-on with standard 3.3 V or 5 V logic-level controllers; ±0.5 V spread improves production yield.
E_oss @ 500 V	2.7 µJ - lowers turn-off energy loss in high-voltage hard-switching applications like PFC.
ESD Class (HBM)	Class 2 - integrated Zener diode provides on-chip protection against handling-induced electrostatic discharge.
P_tot	73 W - rated for TO-220 package with heatsink; supports >20 W adapter designs without forced cooling.

Pinout & Package

Package: PG-TO220-3 (standard through-hole TO-220 variant with isolated tab). Tab is Drain (Pin 2); Gate is Pin 1; Source is Pin 3.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal; low 24 nC Q_g enables fast, low-loss switching with minimal driver stress.
Pin 2 (Tab)	Drain	Main high-voltage power terminal; electrically connected to metal tab for direct heatsinking and low-inductance layout.
Pin 3	Source	Power return path and reference for gate drive; tied to PCB ground plane in most flyback/PFC layouts.

Key Features

Feature	Design Value
Best-in-class R_DS(on) × E_oss FoM	Enables higher efficiency in 65–100 kHz flyback converters without compromising thermal margin.
V_GS(th) = 3 V ±0.5 V	Reduces need for gate voltage margining and improves consistency across production batches.
Integrated Zener ESD protection	Eliminates external gate protection components and reduces BOM count in cost-sensitive consumer power supplies.
Fully JEDEC-qualified for industrial use	Guarantees operation from –55°C to +150°C junction temperature with validated reliability data.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP80R600P7XKSA1	R_DS(on) = 0.6 Ω (max); lower gate charge (19 nC); same V_DS, V_GS(th), and package.	Better suited for higher-efficiency, lower-power (<15 W) adapters where conduction loss is less critical than switching loss.	Select when prioritizing E_oss reduction and gate drive simplicity over R_DS(on)-driven conduction loss.
IPW60R041P7XKSA1	650 V rating; R_DS(on) = 0.041 Ω; Q_g = 52 nC; TO-247 package; no integrated Zener.	Targeted at high-current, lower-voltage PFC and resonant topologies requiring ultra-low R_DS(on).	Choose only for 650 V systems with strict R_DS(on) requirements and available gate drive headroom.

Compared with IPP80R600P7XKSA1, this part trades 0.15 Ω higher R_DS(on) for 11% lower E_oss and identical V_GS(th) stability; versus IPW60R041P7XKSA1, it offers 150 V higher blocking voltage and integrated ESD protection at the cost of higher on-resistance and lower current rating.

FAQ

What is the maximum continuous drain current for IPP80R450P7XKSA1 at 100°C case temperature?

The maximum continuous drain current is 7.1 A at T_C = 100°C, as specified in Table 2 of the datasheet. This derating reflects thermal limits of the TO-220 package and ensures safe operation within the 150°C maximum junction temperature under typical heatsink conditions.

Does IPP80R450P7XKSA1 require an external gate resistor for stability in flyback applications?

Yes-a gate resistor (typically 7.5 Ω, per datasheet switching characterization) is recommended to dampen ringing and control dv/dt during turn-on/off. The device's low Q_g and integrated Zener simplify design but do not eliminate the need for proper gate loop inductance management.

Can IPP80R450P7XKSA1 be paralleled with identical units?

Yes, but with precautions: use individual ferrite beads on each gate line or separate totem-pole drivers to suppress oscillation. The tight V_GS(th) tolerance (±0.5 V) and matched dynamic parameters support stable current sharing when layout symmetry and thermal coupling are maintained.

What is the reverse diode's typical forward voltage at 4.5 A and 25°C?

The typical source-drain diode forward voltage is 0.9 V at I_F = 4.5 A and T_j = 25°C, per Table 7. This value increases to ~1.1 V at 125°C, supporting synchronous rectification evaluation in low-frequency flyback designs where body diode conduction occurs.
