Product details

Overview

IPA80R310CEXKSA1 from Infineon Technologies is an 800 V, 310 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 51 A pulsed drain current, 91 nC total gate charge, and 400 A/µs body diode di/dt capability.

For engineers reviewing the IPA80R310CEXKSA1 datasheet, IPA80R310CEXKSA1 pinout, IPA80R310CEXKSA1 application, or IPA80R310CEXKSA1 equivalent, key selection criteria include 800 V V_DS, low R_DS(on) at 10 V drive, dv/dt ruggedness (50 V/ns), E_oss of 6.7 µJ at 400 V, and TO-220 FP thermal resistance of 3.6 °C/W.

Technical Context

This device implements Infineon's CoolMOS™ CE charge-compensated superjunction architecture, enabling high-voltage operation with reduced switching losses and improved EMI behavior. Its 2320 pF C_iss and 90 pF C_oss support fast, controlled turn-on/off transitions under 400 V bus conditions.

The integrated body diode features 550 ns reverse recovery time and 15 µC Q_rr, making it suitable for quasi-resonant topologies where diode commutation speed and soft recovery reduce voltage overshoot and snubber stress.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - supports 400 V AC input designs with ≥2× safety margin against line surges
R_DS(on), max	310 mΩ @ T_j = 150°C - enables <1.5 W conduction loss at 11 A continuous current
Q_g, typ	91 nC - reduces gate driver power demand and improves switching efficiency in 65–100 kHz QR flybacks
E_oss @ 400 V	6.7 µJ - lowers turn-off energy loss and eases snubber design in high-frequency SMPS
dv/dt ruggedness	50 V/ns - ensures reliable operation without spurious turn-on in noisy high-dV/dt environments
Thermal R_thJC	3.6 °C/W - allows 35 W dissipation at T_C = 25°C, supporting compact heatsink layouts
Body diode di/dt	400 A/µs - sustains fast, controlled commutation during zero-voltage switching transitions

Pinout & Package

IPA80R310CEXKSA1 uses the TO-220 FullPAK (PG-TO220-3-1) package with isolated tab. The plastic body provides reinforced insulation (2500 V_rms withstand), and the copper leadframe enhances thermal performance.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives 10 V logic-level drive; low Q_gd (46 nC) minimizes Miller-induced oscillation risk
Pin 2 / Tab (Drain)	High-side power output	Electrically connected to drain; mounted to heatsink with electrical isolation required
Pin 3 (Source)	Reference node	Serves as return path for gate drive and load current; defines local ground for driver IC

Key Features

Feature	Design Value
Extreme dv/dt rating	50 V/ns - eliminates need for external gate clamping in high-noise industrial adapter designs
Low effective output capacitance	C_o(er) = 59 pF - reduces turn-off loss and improves light-load efficiency in QR flyback
High peak current capability	I_D,pulse = 51 A - supports surge handling during cold-start and overvoltage transients
RoHS-compliant, halogen-free	Pb-free plating + halogen-free mold compound - meets IEC 61249-2-21 and JEDEC J-STD-020 standards

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
IPW65R041CFD7	650 V V_DS, 41 mΩ R_DS(on), 110 nC Q_g, TO-247 package	Lower voltage rating; higher conduction efficiency but unsuitable for 400 V AC universal input	Select only for fixed 230 V AC or DC-fed systems requiring lower R_DS(on)
STP80NF55-08	55 V V_DS, 8 mΩ R_DS(on), 120 nC Q_g, TO-220 package	Not a high-voltage device; incompatible with offline SMPS primary side	Not recommended as functional alternative; belongs to low-voltage logic-level category

Compared with IPW65R041CFD7 and STP80NF55-08, IPA80R310CEXKSA1 uniquely balances 800 V rating, 310 mΩ conduction loss, and 91 nC gate charge for cost-sensitive QR flyback designs-offering optimal trade-off between surge robustness, thermal footprint, and driver simplicity.

FAQ

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

The maximum continuous drain current is 10.6 A at T_C = 100°C, as specified in Table 2 of the Rev. 2.1 datasheet. This value is thermally limited by the 150°C maximum junction temperature and the 3.6 °C/W junction-to-case thermal resistance. Derating follows the P_tot vs. T_C curve in Diagram 1.

Does IPA80R310CEXKSA1 require a negative gate voltage for safe turn-off?

No. The device operates with 0 to +10 V gate drive and does not require negative bias. Its gate threshold voltage (2.1–3.9 V) and 30 V dynamic V_GS rating ensure robust turn-off with standard 0 V gate return. Negative voltage is unnecessary unless mitigating extreme noise in specialized high-dv/dt environments.

Can this MOSFET be paralleled for higher current capacity?

Yes, but with precautions: Infineon recommends using ferrite beads on individual gate lines or separate totem-pole drivers to balance dynamic current sharing. Layout symmetry, matched gate resistors, and identical thermal mounting are essential to avoid current imbalance and thermal runaway.

Is the TO-220 FullPAK package electrically insulated?

Yes. The TO-220 FullPAK variant used in IPA80R310CEXKSA1 features reinforced insulation with 2500 V_rms withstand voltage (1 minute), allowing direct mounting to grounded heatsinks without additional insulating hardware-reducing thermal interface resistance and assembly complexity.
