Product details

Overview

IPA80R460CEXKSA1 from Infineon Technologies is an 800 V, 460 mΩ R_DS(on) CoolMOS™ CE superjunction power MOSFET in TO-220 FullPAK package, optimized for high-efficiency QR flyback converters in LED lighting and AC/DC adapters. It delivers 64 nC gate charge, 33 A pulsed drain current, and 400 A/µs body diode di/dt capability.

For engineers reviewing the IPA80R460CEXKSA1 datasheet, IPA80R460CEXKSA1 pinout, IPA80R460CEXKSA1 application, or IPA80R460CEXKSA1 equivalent, key selection criteria include 800 V V_DS rating, low Q_g for soft-switching compatibility, dv/dt ruggedness (50 V/ns), and thermal resistance (R_thJC = 3.7 °C/W) in high-density power supplies.

Technical Context

This device implements Infineon's CoolMOS™ CE charge-compensated superjunction architecture, enabling high-voltage blocking with reduced specific on-resistance. Its 460 mΩ R_DS(on) at V_GS = 10 V and T_j = 25°C supports compact heatsinking in 65–100 W offline SMPS designs.

The MOSFET features a fully rated 800 V V_(BR)DSS, extreme dv/dt immunity (50 V/ns), and integrated body diode with 550 ns reverse recovery time and 10 µC Q_rr, making it suitable for quasi-resonant operation where hard commutation stress is minimized.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - Enables direct rectified mains operation up to 380 V DC input without series stacking.
R_DS(on), max	460 mΩ @ V_GS=10 V, T_j=25°C - Sets conduction loss floor in QR flyback primary switch; impacts thermal design at 10.8 A continuous current.
Q_g, typ	64 nC - Determines gate drive power and switching speed; enables efficient operation with standard 10 V gate drivers.
E_oss@400V	4.6 µJ - Defines turn-on energy loss during zero-voltage switching transitions in QR topology.
dv/dt ruggedness	50 V/ns - Ensures reliable operation under fast voltage transients common in high-frequency flyback snubbers.
Body diode di/dt	400 A/µs - Supports fast freewheeling in discontinuous conduction mode without oscillation or latch-up.

Pinout & Package

IPA80R460CEXKSA1 uses the TO-220 FullPAK (PG-TO220-3-1) package with isolated tab. The drain is connected to the metal tab and Pin 2; gate is Pin 1; source is Pin 3. This configuration supports direct heatsink mounting with electrical isolation.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	High-impedance control terminal requiring <64 nC charge for full enhancement; referenced to source.
Pin 2 / Tab	Drain	Main high-voltage power terminal; electrically tied to exposed metal tab for low-inductance, high-current path and thermal conduction.
Pin 3	Source	Power return node and gate reference; connects to primary ground in flyback circuits.

Key Features

Feature	Design Value
800 V high-voltage technology	Enables single-device operation across universal AC input (85–265 VAC) with margin for surge and line spikes.
Low effective output capacitance (C_o(er) = 50 pF)	Reduces turn-on switching loss and improves ZVS behavior in QR flyback at 65–130 kHz.
Extreme dv/dt rating (50 V/ns)	Prevents false turn-on during high dV/dt events in transformer leakage inductance ringing.
RoHS-compliant, halogen-free mold compound	Meets environmental compliance requirements for consumer-grade lighting and adapter products.

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 R_DS(on), higher Q_g (120 nC), TO-220 package without isolated tab	Higher conduction loss at same current; requires external isolation for heatsink mounting	Preferred when lower R_DS(on) outweighs gate drive complexity and thermal interface cost
IPP60R460C6	600 V, 460 mΩ R_DS(on), CoolMOS™ C6 generation, lower Q_g (49 nC), same TO-220 FullPAK	Not suitable for 380 V DC bus; limited to ≤265 VAC universal input	Select only for cost-sensitive 600 V designs where peak line voltage stays below 350 V

Compared with STP80NF55-08 and IPP60R460C6, IPA80R460CEXKSA1 uniquely balances 800 V rating, moderate R_DS(on), and low Q_g in an isolated-tab package-enabling simpler thermal design and higher system-level efficiency in universal-input QR flybacks.

FAQ

What is the maximum continuous drain current for IPA80R460CEXKSA1 at 100°C case temperature?

The maximum continuous drain current is 6.8 A at T_C = 100°C, as specified in Table 2 of the datasheet. This limit is set by junction temperature constraints (T_j ≤ 150°C) and thermal resistance (R_thJC = 3.7 °C/W). Derating must be applied above 25°C case temperature using the linear curve in Diagram 1.

Does IPA80R460CEXKSA1 have an integrated body diode, and what are its key parameters?

Yes, it includes a fast-recovery body diode with V_SD = 1 V at I_F = 10.8 A and T_j = 25°C, t_rr = 550 ns, Q_rr = 10 µC, and di/dt capability of 400 A/µs. These values are measured under V_R = 400 V and di_F/dt = 100 A/µs conditions, supporting reliable freewheeling in DCM flyback operation.

Can IPA80R460CEXKSA1 be paralleled with identical units, and what layout guidance applies?

Yes, parallel operation is supported but requires individual gate ferrite beads or separate totem-pole drivers to suppress oscillation and ensure current sharing. Layout must minimize loop inductance, match trace lengths, and use Kelvin-source connections. Gate resistors should be placed close to each device's gate pin to dampen ringing.

Is IPA80R460CEXKSA1 compliant with RoHS and halogen-free standards?

Yes, it carries Pb-free plating and uses a halogen-free mold compound, meeting RoHS Directive 2011/65/EU and JEDEC JS709B requirements. The "XKSA1" suffix confirms full compliance, including exemption status for lead in high-melting-temperature solder alloys per Annex III.
