Product details

Overview

IPW80R290C3A from Infineon Technologies is an AEC-Q101 qualified 800 V CoolMOS® C3A superjunction power MOSFET in PG-TO247-3 package, featuring R_DS(on) max = 0.29 Ω at 10 V_GS, Q_g typ = 91 nC, and 17 A continuous drain current at T_C = 25 °C. It delivers ultra-low gate charge and effective output capacitance for high-efficiency DC/DC converters in automotive power systems.

For engineers reviewing the IPW80R290C3A datasheet, IPW80R290C3A pinout, IPW80R290C3A application, or IPW80R290C3A equivalent, key selection criteria include its 800 V breakdown voltage, 0.25 Ω typical R_DS(on) at 150 °C, dv/dt ruggedness up to 640 V/ns, 670 mJ single-pulse avalanche energy, and AEC-Q101 qualification for under-hood automotive use.

Technical Context

This 800 V superjunction MOSFET uses Infineon's CoolMOS® C3A technology to minimize conduction and switching losses simultaneously. Its low C_iss (2300 pF) and C_oss (94 pF), combined with 45 nC Q_gd, enable fast, soft-switching operation in hard-switched and resonant topologies.

The device integrates a robust body diode with t_rr = 550 ns and Q_rr = 15 µC, supporting synchronous rectification and freewheeling in bidirectional DC/DC stages. Its thermal resistance R_thJC = 0.55 K/W ensures efficient heat transfer in high-power-density automotive modules.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STW80N80F3	800 V, R_DS(on) max = 0.30 Ω, Q_g = 105 nC, not AEC-Q101 qualified	Limited to industrial or non-safety-critical automotive after-market use	Select only if AEC-Q101 compliance is not required and higher gate charge is acceptable.
IPP80R290C3	Same die, PG-TO220FP package, R_thJC = 1.1 K/W, lower I_D rating (13 A)	Suitable for lower-power, cost-sensitive modules where thermal performance allows TO-220 footprint	Choose when board space permits larger footprint and thermal budget supports higher junction rise.

Compared with STW80N80F3 and IPP80R290C3, IPW80R290C3A uniquely combines AEC-Q101 qualification, lowest R_thJC (0.55 K/W), and highest pulsed current rating (51 A), making it optimal for thermally constrained, safety-critical automotive DC/DC stages.

FAQ

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

The IPW80R290C3A supports 11 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the PG-TO247-3 package and ensures safe operation within R_thJC = 0.55 K/W and T_j,max = 150 °C constraints under real-world heatsink conditions.

Is the body diode suitable for synchronous rectification?

Yes-the integrated body diode features t_rr = 550 ns and Q_rr = 15 µC with soft recovery characteristics, validated for synchronous rectification in forward and LLC topologies. However, external Schottky diodes may be preferred for ultra-low V_SD in high-frequency, low-voltage-output designs.

Does this part require negative gate voltage for reliable turn-off?

No-IPW80R290C3A has a gate threshold voltage V_GS(th) of 2.1–3.9 V and is fully controllable with 0 V to +10 V gate drive. Negative gate bias is not required, though a small negative turn-off voltage (e.g., –2 V) can improve noise immunity in high-dv/dt environments.

How does dv/dt ruggedness impact PCB layout?

The rated 640 V/ns dv/dt ruggedness demands minimized source inductance: keep gate loop area tiny, use Kelvin source connection if possible, and place gate driver within 1 cm of the source pin. Layout-induced L_source > 5 nH risks false turn-on during V_DS transitions, especially in full-bridge configurations.
