Product details

Overview

IPP50R250CPHKSA1 from Infineon Technologies is a 500 V, 14 A, 250 mΩ N-channel CoolMOS™ C7 superjunction MOSFET in TO-220FP package, optimized for high-efficiency SMPS, PFC stages, and industrial AC-DC converters operating at 65–300 kHz. It features 100% avalanche-rated ruggedness, low gate charge (Q_g = 29 nC), and reduced E_oss (1.8 µJ @ 400 V) for improved hard-switching efficiency.

For engineers reviewing the IPP50R250CPHKSA1 datasheet, IPP50R250CPHKSA1 pinout, IPP50R250CPHKSA1 application, or IPP50R250CPHKSA1 equivalent, key selection criteria include R_DS(on) temperature stability, gate threshold voltage (V_GS(th) = 3.5 V typ), safe operating area (SOA) in linear mode, and compatibility with standard 12 V gate drivers in continuous conduction mode (CCM) PFC designs.

Technical Context

This device belongs to Infineon's CoolMOS™ C7 family, employing field-stop trench technology with optimized charge balancing for reduced conduction and switching losses. Its V_GS(th) of 3.5 V enables reliable turn-on with standard logic-level gate drivers while maintaining noise immunity via a 1.5 V hysteresis window.

The MOSFET supports hard-switched topologies up to 300 kHz and soft-switched resonant operation, with specified R_DS(on) of 250 mΩ at T_j = 25°C and 390 mΩ at T_j = 100°C-enabling accurate thermal modeling in enclosed power supplies and motor drives.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	500 V - Withstands full mains surge (e.g., 380 VAC + 100 V transient) without breakdown
R_DS(on) max	250 mΩ @ T_j = 25°C - Enables <1.5 W conduction loss at 14 A DC in compact heatsink designs
I_D (continuous)	14 A @ T_c = 25°C - Supports ≥200 W output in 20 mm² PCB copper area with forced air cooling
Q_g	29 nC - Reduces gate drive power requirement and allows use of low-cost 1-A peak drivers
E_oss	1.8 µJ @ V_DS = 400 V - Lowers turn-off energy loss in high-frequency PFC boost stages
SOA (linear mode)	Rated for 10 ms, 100 V, 10 A - Ensures robustness during overload and short-circuit events

Pinout & Package

TO-220FP (full-pack) package with isolated tab, 3-pin through-hole mounting, 1.5 mm creepage/clearance, and 1.25 W/K thermal resistance (R_thJC).

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current path collector	Connected directly to heatsink via isolated tab; requires no insulating washer when mounted on grounded metal chassis
Gate (G)	Control input terminal	High-impedance MOS gate requiring ≤29 nC charge for full enhancement; sensitive to ESD (HBM Class 1B)
Source (S)	Reference node for gate drive	Serves as return path for load current and gate driver loop; must be low-inductance layout to prevent oscillation

Key Features

Feature	Design Value
Optimized R_DS(on) × Q_g figure-of-merit	7.25 Ω·nC - Delivers best-in-class trade-off between conduction loss and switching loss for 500 V class
100% unclamped inductive switching (UIS) rated	250 mJ @ T_j = 25°C - Guarantees single-pulse avalanche survivability without derating
Enhanced dv/dt ruggedness	4.5 kV/µs - Prevents false turn-on in high-noise bridge-leg configurations
Reduced E_oss vs. prior CoolMOS™ generations	−35% vs. C3 - Directly lowers turn-off loss in 100–300 kHz PFC and LLC primary switches

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	500 V, 4.5 A, 1.2 Ω R_DS(on), Zener-protected gate, higher Q_g (45 nC)	Limited to ≤100 W due to lower current rating and higher conduction loss	Select only for cost-sensitive, low-power (<100 W), non-avalance-critical designs where gate protection is prioritized
IXTH12N50L2	500 V, 12 A, 480 mΩ R_DS(on), lateral MOSFET with lower dv/dt immunity (2.5 kV/µs)	Requires snubber network in fast-switching PFC; unsuitable for high-density layouts	Prefer only in legacy designs with existing snubber circuits and where layout space permits added components

Compared with STP5NK50ZFP and IXTH12N50L2, IPP50R250CPHKSA1 delivers 5.6× lower R_DS(on) than the ST part and 1.9× lower than the IXYS device-enabling 200+ W higher power density, elimination of gate snubbers, and direct compatibility with industry-standard 12 V gate drivers without level-shifting.

FAQ

What is the maximum recommended case temperature for continuous operation?

The IPP50R250CPHKSA1 is rated for continuous operation up to T_c = 100°C when mounted on a 25 mm² copper pad with 1 oz. thickness and no airflow. Derating is required above this temperature: R_DS(on) increases by 0.5%/°C, and SOA limits reduce linearly to 50% at T_c = 125°C per Infineon's Application Note AN2017-05.

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

No. The device has a positive V_GS(th) of 3.5 V (typ) and is fully enhanced at V_GS = 10 V. A gate drive swing of 0 V to +12 V is sufficient for robust switching; negative voltage is not required or recommended, as it offers no benefit and risks overstressing the gate oxide beyond its ±20 V absolute maximum rating.

Can IPP50R250CPHKSA1 replace IPP50R250CP in an existing design?

Yes-IPP50R250CPHKSA1 is a drop-in replacement for IPP50R250CP (same package, pinout, and R_DS(on) spec), but with improved E_oss, tighter V_GS(th) distribution (±0.3 V), and extended UIS rating. No layout or gate drive changes are needed; efficiency gains of 0.3–0.5% are typical in PFC stages operating above 100 kHz.

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

Yes. IPP50R250CPHKSA1 uses lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The "KSA1" suffix denotes Infineon's standard green packaging, including halogen-free molding compound and matte tin-plated leads with <1000 ppm total halogens.
