Product details

Overview

IPA50R280CE from Infineon Technologies is a 500 V, 0.28 Ω R_DS(on) CoolMOS™ CE superjunction power MOSFET in PG-TO220 FP package, optimized for high-efficiency PFC and hard-switching SMPS stages in consumer lighting and adapter applications. It delivers 18.1 A continuous drain current at T_C = 25°C, 32.6 nC total gate charge, and 3.2 µJ output switching energy at 400 V.

For engineers reviewing the IPA50R280CE datasheet, IPA50R280CE pinout, IPA50R280CE application, or IPA50R280CE equivalent, key selection criteria include its low FOM (R_DS(on) × Q_g), high commutation ruggedness (500 A/µs di/dt), and TO-220 FullPAK insulation rating of 2500 V_RMS, critical for isolated AC-DC designs.

Technical Context

This CoolMOS™ CE device implements a superjunction cell structure enabling reduced conduction and switching losses simultaneously. Its 5.3 V gate plateau voltage and 17.1 nC Q_gd support stable hard-switching operation up to 400 V DC-link with minimal Miller-induced shoot-through risk.

Thermal design is enabled by a 4.11 °C/W junction-to-case resistance and 30.4 W power dissipation capability at T_C = 25°C. The integrated fast-recovery body diode (t_rr = 230 ns, Q_rr = 2.2 µC) supports resonant topologies without external antiparallel diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	500 V - Maximum blocking voltage for 400 V DC-link PFC and offline SMPS stages
R_DS(on),max	0.28 Ω @ T_j = 150°C - Enables <1.5 W conduction loss at 4.2 A RMS in 230 VAC input PFC
Q_g,typ	32.6 nC @ V_DD = 400 V - Determines gate driver power requirement and switching speed control
E_oss	3.2 µJ @ 400 V - Directly impacts turn-off loss in hard-switched converters operating above 65 kHz
I_D,pulsed	42.9 A - Supports peak current handling during startup, overload, and inrush in lighting ballasts
t_rr	230 ns - Limits reverse recovery stress during zero-voltage switching transitions

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP5NK50ZFP	Zener-protected avalanche-rated 500 V MOSFET; higher R_DS(on) (0.6 Ω) and Q_g (42 nC); no integrated diode optimization	Better suited for non-resonant, low-frequency (<30 kHz) flyback where avalanche robustness outweighs efficiency needs	Select when cost is primary constraint and thermal margin exceeds 15°C; avoid in PFC or high-frequency resonant designs
IPP60R099C6	600 V CoolMOS™ C6; lower R_DS(on) (0.099 Ω) but higher Q_g (62 nC); improved E_oss (1.9 µJ) and tighter V_GS(th) tolerance	Targeted at high-power (>600 W), high-efficiency server PSUs requiring tighter parametric consistency	Choose for next-gen designs needing higher power density and tighter production binning; not drop-in due to gate drive timing differences

Compared with STP5NK50ZFP and IPP60R099C6, IPA50R280CE offers the optimal balance of cost, efficiency, and ease-of-use for sub-500 W consumer power supplies-delivering 12% lower conduction loss than STP5NK50ZFP while requiring 47% less gate drive energy than IPP60R099C6.

FAQ

What is the maximum recommended gate resistor value for reliable turn-on in a 100 kHz PFC application?

Based on the 32.6 nC Q_g and 5.3 V gate plateau, a 10 Ω gate resistor ensures <330 ns turn-on delay and <1.5 V overshoot with standard 1 A peak gate drivers. Values above 15 Ω increase switching loss disproportionately and may cause incomplete turn-on at high temperature due to V_GS(th) drift.

Can IPA50R280CE be paralleled in a 1 kW PFC design?

Yes, but only with gate ferrite beads (600 Ω @ 100 MHz) on each MOSFET's gate line and individual 4.7 Ω source resistors to balance dynamic current sharing. Parallel operation requires matched layout symmetry and thermal coupling; derate total current by 20% versus single-device rating.

Does the TO-220 FullPAK package require special soldering profile considerations?

Yes-the insulated case mandates wave soldering only on leads (1.6 mm from case, 260°C for 10 s). Reflow is not permitted. Thermal pad under the tab must remain un-soldered; mechanical mounting via M2.5 screws is required for thermal and electrical integrity.

How does the body diode's reverse recovery performance compare to discrete SiC Schottky alternatives?

The IPA50R280CE body diode has t_rr = 230 ns and Q_rr = 2.2 µC-significantly slower than SiC Schottky diodes (t_rr ≈ 0 ns), but sufficient for soft-switched topologies like LLC where di/dt is limited. In hard-switched applications, an external SiC diode is recommended to eliminate recovery loss.
