Product details

Overview

IPA80R460CEXKSA2 from Infineon Technologies is an 800 V, 460 mΩ CoolMOS™ CE superjunction power MOSFET in TO-220 FullPAK package, rated for 10.8 A continuous drain current at 25°C and optimized for quasi-resonant flyback converters in LED lighting and AC/DC adapters. It features 64 nC total gate charge, 4.6 µJ output switching energy at 400 V, and 400 A/µs body diode commutation speed.

For engineers reviewing the IPA80R460CEXKSA2 datasheet, IPA80R460CEXKSA2 pinout, IPA80R460CEXKSA2 application, or IPA80R460CEXKSA2 equivalent, key selection criteria include R_DS(on) stability over temperature, dv/dt ruggedness (50 V/ns), E_oss performance, and gate drive compatibility with QR flyback controllers such as ICE2QS03 or UCC28740.

Technical Context

This device implements Infineon's CoolMOS™ CE charge-compensated superjunction architecture, enabling high-voltage blocking with low conduction and switching losses. Its 800 V V_(BR)DSS, 2.1–3.9 V gate threshold, and 5.5 V gate plateau voltage support robust gate drive design in isolated SMPS topologies.

The MOSFET integrates a fast-recovery body diode (t_rr = 550 ns, Q_rr = 10 µC) and exhibits extreme dv/dt immunity (50 V/ns) and high peak current capability (33 A pulsed), making it suitable for high-frequency, high-efficiency QR flyback operation without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - Enables direct rectified 380 V DC input handling in universal-input offline SMPS without cascading devices.
R_DS(on), max	460 mΩ @ T_j = 25°C - Sets conduction loss floor in QR flyback primary side; increases to ~1.05 Ω at 150°C.
Q_g, typ	64 nC - Determines gate driver current requirement and influences switching transition time and E_oss-related losses.
E_oss @ 400 V	4.6 µJ - Quantifies energy dissipated during turn-off; directly impacts efficiency in high-frequency QR operation.
Body diode dI/dt	400 A/µs - Supports fast zero-current switching transitions in QR flyback valley switching without oscillation.
Thermal R_thJC	3.7 °C/W - Defines junction-to-case thermal path; enables 34 W power dissipation at T_C = 25°C with appropriate heatsinking.

Pinout & Package

IPA80R460CEXKSA2 is housed in a TO-220 FullPAK (PG-TO220-3-1) package with isolated drain tab. The plastic body provides reinforced insulation (V_ISO = 2500 V_RMS), and the tab serves as the drain terminal for direct heatsink mounting.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Lead)	Gate	Control electrode; requires low-impedance drive due to 64 nC Q_g; sensitive to ESD and ringing.
Pin 2 / Tab	Drain	Main high-voltage power terminal; electrically connected to metal tab for thermal and electrical integration with heatsink.
Pin 3 (Lead)	Source	Reference node for gate drive; carries full switched current and must be routed with low inductance.

Key Features

Feature	Design Value
Extreme dv/dt rating	50 V/ns - Ensures reliable operation under fast voltage transients in high-frequency QR flyback without false turn-on.
Low effective output capacitance	C_o(er) = 50 pF - Reduces turn-off loss and improves valley-switching accuracy in QR topologies.
High peak current capability	I_D,pulse = 33 A - Supports surge currents during startup and overload conditions without failure.
RoHS-compliant & halogen-free	Pb-free plating and mold compound - Meets environmental compliance requirements for consumer-grade LED lighting and adapter applications.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP80NF55-08	800 V, 0.08 Ω, TO-220; higher R_DS(on), no Co(er) optimization, slower t_r/t_f	Limited to lower-frequency hard-switched flyback; less efficient in QR mode above 65 kHz	Prefer IPA80R460CEXKSA2 when E_oss and valley-switching precision are critical.
IPP60R460C7	650 V, 460 mΩ, TO-220; lower voltage rating, improved FOM, but unsuitable for 400 V DC bus	Requires input voltage derating or PFC stage; not viable for universal-input offline without boost pre-regulator	Select IPA80R460CEXKSA2 for direct 800 V-rated operation in cost-sensitive universal-input designs.

Compared with STP80NF55-08 and IPP60R460C7, IPA80R460CEXKSA2 uniquely balances 800 V rating, low E_oss, and high dv/dt immunity-enabling simpler, more efficient QR flyback designs without voltage clamping or gate ferrite beads in most cases.

FAQ

What is the maximum recommended gate resistor value for IPA80R460CEXKSA2 in QR flyback applications?

A gate resistor of 7.5 Ω is specified in the datasheet for dynamic characterization (td(on), tr, etc.) under 400 V VDD and 10.8 A ID. For QR flyback, values between 5 Ω and 15 Ω are typical: lower values improve switching speed but increase EMI risk; higher values reduce ringing but raise switching losses. Ferrite beads are recommended if paralleling multiple units.

Does IPA80R460CEXKSA2 require a negative gate turn-off voltage?

No. The device is rated for ±30 V dynamic gate-source voltage, but standard operation uses 0 V to +10 V or +12 V gate drive. A negative turn-off voltage is not required due to its high dv/dt immunity (50 V/ns) and low Q_gd/Q_gs ratio, which suppresses Miller-induced false turn-on in QR flyback circuits.

Can IPA80R460CEXKSA2 replace IPA80R460CP in existing designs?

Yes-IPA80R460CEXKSA2 and IPA80R460CP share identical electrical specs, pinout, and TO-220 FullPAK package. The 'XKSA2' suffix denotes tape-and-reel packaging and RoHS/halogen-free compliance per JEDEC standards, with no functional or thermal differences affecting board-level design or layout.

What is the safe operating area (SOA) limitation at 100°C case temperature?

At T_C = 100°C, the continuous drain current is derated to 6.8 A (per Table 2). The SOA curve (Diagram 3) shows that at V_DS = 400 V, the device supports ≤4.5 A DC, or up to 10.8 A for pulses <100 µs. Thermal design must maintain T_C ≤ 100°C to avoid exceeding R_thJC = 3.7 °C/W limits.
