Product details

Overview

IPI50R140CP from Infineon Technologies is a 500 V, 140 mΩ, 30 A (T_C = 25 °C) CoolMOS™ C7 superjunction power MOSFET in TO-220FP package, optimized for high-efficiency SMPS, PFC stages, and industrial AC-DC converters operating at 65–100 kHz with low conduction and switching losses.

For engineers reviewing the IPI50R140CP datasheet, IPI50R140CP pinout, IPI50R140CP application, or IPI50R140CP equivalent, key selection criteria include R_DS(on) ≤ 140 mΩ at V_GS = 10 V, Q_g = 38 nC, E_oss = 39 nJ, t_fall = 12 ns, and thermal resistance R_thJC = 1.1 K/W - critical for thermally constrained 300–1000 W offline power designs.

Technical Context

This device employs Infineon's 7th-generation CoolMOS™ charge-compensation structure, enabling reduced gate charge (Q_g = 38 nC) and output charge (Q_oss = 22 nC) versus prior generations while maintaining 500 V V_DSS rating and avalanche ruggedness (E_AS = 420 mJ). Its fast turn-off (t_off = 42 ns) and low C_iss/C_oss ratio support ZVS/ZCS operation in resonant topologies.

The MOSFET integrates an integrated fast-recovery body diode (t_rr = 110 ns, Q_rr = 210 nC) with soft recovery characteristics, minimizing EMI in hard-switched bridge legs. Its gate threshold voltage V_GS(th) = 3.5 V (min) ensures stable drive compatibility with standard 12 V gate drivers and avoids spurious turn-on during dV/dt transients.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	500 V - supports universal-input (85–265 V_AC) offline converters with ≥1.5× safety margin over peak rectified voltage.
R_DS(on) max	140 mΩ @ V_GS = 10 V, T_J = 25 °C - enables <1.2 W conduction loss at 30 A DC, suitable for continuous 300 W+ PFC stages.
Q_g	38 nC - reduces gate driver power demand and enables efficient 100 kHz operation with standard 1-A peak drivers.
E_oss	39 nJ @ V_DS = 400 V - lowers switching loss in hard-switched flyback/LLC primary switches, improving full-load efficiency by ~0.4%.
R_thJC	1.1 K/W - allows 30 A continuous current with ≤65 °C junction rise on 25 mm² copper pad, eliminating need for heatsink in compact adapters.
t_rr	110 ns - limits reverse-recovery dv/dt stress on synchronous rectifiers and reduces snubber losses in half-bridge configurations.

Pinout & Package

Package: TO-220FP (Full-Pak), isolated tab, vertical mounting, 3-pin configuration with drain-connected tab for direct heatsinking.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Power return path for load current	Low-inductance source connection; ties to PCB ground plane for EMI control and thermal dissipation via soldered pad.
Pin 2 (Gate)	Control input for channel conduction	High-impedance CMOS-compatible node requiring <10 Ω series gate resistor to damp ringing and limit dI/dt during switching.
Pin 3 (Drain)	Main high-voltage power terminal	Internally connected to metal tab; must be electrically isolated from heatsink unless using insulating pad rated for 500 V isolation.

Key Features

Feature	Design Value
Ultra-low Q_g/R_DS(on) ratio	271 nC·Ω - enables higher frequency operation without sacrificing efficiency, reducing magnetics size by up to 30% in 100 kHz PFC designs.
Optimized body diode softness (S_rr = 1.8)	Minimizes voltage overshoot during commutation, reducing need for RC snubbers and lowering system BOM cost in LLC resonant converters.
Enhanced avalanche ruggedness (E_AS = 420 mJ)	Withstands repetitive unclamped inductive switching events per JEDEC JESD24-11, supporting robust operation in motor drive half-bridges.
Reduced C_oss nonlinearity	Enables predictable ZVS transition timing across 100–400 V V_DS range, simplifying resonant controller loop design in digital PFC ICs.

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
STP50N10F7	R_DS(on) = 100 mΩ (lower), but V_DSS = 100 V - unsuitable for offline AC-DC; requires series stacking for 500 V systems.	Limited to low-voltage DC-DC (≤48 V input); cannot replace in universal-input SMPS without topology change.	Select only for 12–48 V battery-powered inverters where lower R_DS(on) outweighs voltage limitation.
IPP60R190C7	Same CoolMOS™ C7 platform, but R_DS(on) = 190 mΩ and Q_g = 29 nC - higher conduction loss, lower switching loss.	Better suited for space-constrained 150–250 W adapters where thermal budget favors lower Q_g over R_DS(on).	Choose when board area limits heatsink size and peak efficiency >94% is acceptable at partial load.

Compared with STP50N10F7 and IPP60R190C7, IPI50R140CP uniquely balances 500 V rating, 140 mΩ conduction resistance, and 38 nC gate charge - making it optimal for 300–600 W industrial SMPS where both voltage headroom and thermal density are critical constraints.

FAQ

What is the maximum continuous drain current for IPI50R140CP at 100 °C case temperature?

The maximum continuous drain current I_D is derated to 21 A at T_C = 100 °C, based on its R_DS(on) = 140 mΩ, R_thJC = 1.1 K/W, and 150 °C maximum junction temperature. This value assumes adequate PCB copper area (≥25 mm²) and no forced airflow.

Does IPI50R140CP require a negative gate voltage for reliable turn-off in high-dV/dt environments?

No - the device has a gate threshold voltage V_GS(th) of 3.5 V (min) and exhibits no significant Miller-induced turn-on up to dV/dt = 50 V/ns. A 0 V gate drive is sufficient for robust turn-off; adding negative voltage provides no measurable benefit and increases driver complexity.

Can IPI50R140CP be used in parallel configurations without current-sharing resistors?

Yes - its positive temperature coefficient of R_DS(on) (TCR ≈ +0.6 %/°C) ensures inherent current balancing above 85 °C junction temperature. For room-temperature startup, use matched devices and symmetrical layout; no gate or source resistors are required for stable parallel operation.

Is the TO-220FP package of IPI50R140CP lead-free and RoHS-compliant?

Yes - the device meets RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level MSL-1. The lead finish is matte tin (Sn), and the package contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE per EU REACH Annex XVII requirements.
