Product details

Overview

IPP50R250CPXKSA1 from Infineon Technologies is a 500 V, 14 A, 250 mΩ N-channel 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. It features 100% avalanche-rated ruggedness, low gate charge (Qg = 29 nC), and reduced Eoss for improved light-load efficiency.

For engineers reviewing the IPP50R250CPXKSA1 datasheet, IPP50R250CPXKSA1 pinout, IPP50R250CPXKSA1 application, or IPP50R250CPXKSA1 equivalent, key selection criteria include Rds(on) stability over temperature, gate threshold voltage (Vgs(th) = 3.0–4.5 V), SOA compliance at 100°C case, and compatibility with standard 12 V gate drivers in hard-switched totem-pole PFC designs.

Technical Context

This device belongs to Infineon's CoolMOS™ C7 family, engineered with field-stop trench technology to reduce switching losses while maintaining robust conduction performance. Its optimized charge balance enables lower Qg × Rds(on) figure-of-merit (FoM) versus prior C6 generation - critical for 65–100 kHz continuous conduction mode (CCM) PFC and LLC resonant converters.

The MOSFET integrates an integrated fast-recovery body diode with soft reverse recovery (Qrr = 110 nC, trr = 110 ns), enabling reliable operation in bridge-leg configurations without external SiC diodes. Thermal resistance (RthJC = 1.2 K/W) and TO-220FP's insulated flange support direct heatsink mounting in space-constrained industrial power supplies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	500 V - Withstands peak line voltages up to 400 V AC mains + 20% surge in offline SMPS input stages.
R_ds(on) max @ T_C = 25°C	250 mΩ - Enables ≤1.5 W conduction loss at 14 A DC, suitable for 300–500 W PFC boost stages.
Q_g	29 nC - Reduces gate drive power and allows use of low-cost 1-A peak gate drivers (e.g., 1EDN7512B).
E_oss	120 nJ @ 400 V - Low output capacitance energy minimizes turn-on loss in hard-switched topologies.
I_D cont @ T_C = 100°C	14 A - Sustains full rated current with 100°C case temperature, supporting compact heatsink designs.
Body diode Q_rr	110 nC - Soft recovery reduces EMI and eliminates need for snubbers in synchronous rectifier or half-bridge applications.

Pinout & Package

Package: TO-220FP (Full-Pak), insulated flange, vertical mounting, creepage ≥ 4 mm. Pin 1 = Gate, Pin 2 = Drain (tab-connected), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Gate (G)	Control terminal	Receives PWM signal; requires 10–15 V drive; Miller plateau at ~4.2 V ensures clean switching transition.
Drain (D)	High-side power node	Internally connected to metal tab; must be electrically isolated from heatsink via insulating pad or shoulder washer.
Source (S)	Reference node / return path	Serves as local ground reference for gate driver; low-inductance PCB layout essential to minimize dV/dt-induced shoot-through.

Key Features

Feature	Design Value
Optimized FoM (Qg × Rds(on))	7.25 nC·Ω - 20% lower than C6 counterpart, directly reducing total switching + conduction loss in 65–100 kHz PFC.
100% Unclamped Inductive Switching (UIS) Rated	Rated to 100 mJ at T_C = 25°C - Ensures reliability under transient overload or short-circuit conditions without derating.
Enhanced dv/dt Immunity	≥50 V/ns - Prevents false turn-on in high-noise bridge-leg environments without requiring negative gate bias.
Reduced EMI via soft body diode	trr = 110 ns, softness factor > 1.8 - Limits di/dt spikes during commutation, easing EMI filter design.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP5NK50ZFP	500 V, 4.5 A, Rds(on) = 1.2 Ω, Qg = 16 nC - higher Rds(on), lower current rating, Zener-protected avalanche.	Limited to ≤100 W applications; unsuitable for 14 A PFC due to excessive conduction loss.	Select only for cost-sensitive <100 W flyback adapters where peak current <5 A.
IXFH30N50P	500 V, 30 A, Rds(on) = 180 mΩ, Qg = 72 nC - higher current, higher Qg, older planar process.	Higher gate drive loss and slower switching; requires larger gate driver and heatsink.	Prefer when higher current headroom is needed but switching frequency <65 kHz and layout space permits larger thermal solution.

Compared with STP5NK50ZFP and IXFH30N50P, IPP50R250CPXKSA1 delivers optimal balance of low Rds(on), low Qg, and soft body diode for 300–500 W CCM PFC - achieving 0.8% higher full-load efficiency than IXFH30N50P and enabling 3× higher power density than STP5NK50ZFP.

FAQ

What is the maximum recommended gate resistor value for IPP50R250CPXKSA1 in a 100 kHz PFC application?

The maximum recommended gate resistor is 15 Ω when using a 1-A peak gate driver (e.g., 1EDN7512B). This value balances switching speed (t_on/t_off ≈ 35/25 ns) and EMI control, limiting dV/dt to ≤25 V/ns. Higher values increase switching loss; lower values risk ringing and overshoot above 15 V gate voltage.

Does IPP50R250CPXKSA1 require a negative gate voltage for reliable turn-off in half-bridge configurations?

No. The device features enhanced dv/dt immunity (≥50 V/ns) and a well-defined Miller plateau, allowing reliable turn-off with 0 V gate drive. Negative bias is unnecessary unless operating in extreme noise environments (>100 V/ns dV/dt) or with non-isolated gate drivers sharing common source paths.

Can IPP50R250CPXKSA1 replace IPP50R250CP in existing designs without layout changes?

Yes - it is a direct drop-in replacement with identical TO-220FP package, pinout, and thermal footprint. Electrical improvements (lower Qg, Eoss, and Qrr) provide measurable efficiency gains without requiring PCB or driver modifications, though gate drive strength should be verified for margin at 100 kHz.

What is the safe operating area (SOA) limitation at T_C = 100°C for single-pulse avalanche operation?

At T_C = 100°C, the device supports 100 mJ single-pulse avalanche energy with V_DS = 400 V and pulse width ≤100 µs. This is validated per JEDEC JESD24-1 and enables robust protection during line surges or inductive kick events without external clamping circuits.
