Product details

Overview

IPD50R399CPATMA1 from Infineon Technologies is a 550 V, 4.9 A CoolMOS™ CP superjunction power MOSFET in PG-TO252 (DPAK) package, optimized for hard- and soft-switching SMPS topologies with R_DS(on) = 0.399 Ω (max), Q_g = 17 nC (typ), and dv/dt ruggedness up to 400 V/ns. It delivers high peak current capability and industrial-grade reliability for lamp ballast PFC and LCD/PDP TV PWM stages.

For engineers reviewing the IPD50R399CPATMA1 datasheet, IPD50R399CPATMA1 pinout, IPD50R399CPATMA1 application, or IPD50R399CPATMA1 equivalent, key selection criteria include its 550 V V_BR(DSS), 0.399 Ω R_DS(on) at 150 °C, 215 mJ single-pulse avalanche energy, ultra-low gate charge, and TO252 thermal resistance of 1.5 K/W (junction-to-case).

Technical Context

This device implements a superjunction trench-gate structure enabling simultaneous low conduction loss (R_DS(on) × Q_g FoM = 6.8 Ω·nC) and high switching robustness. Its extreme dv/dt rating (400 V/ns) and 12.2 A peak reverse recovery current support fast, reliable operation in discontinuous conduction mode (DCM) PFC and resonant LLC converters.

The integrated body diode features t_rr = 260 ns and Q_rr = 1.9 µC at T_j = 25 °C, with V_SD = 0.9–1.2 V at I_F = 4.9 A - enabling efficient freewheeling in half-bridge and synchronous rectification configurations without external diode supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR(DSS)	550 V - Withstands DC link voltages up to 400 V in PFC and 380 V in offline SMPS with margin.
R_DS(on) max	0.399 Ω @ T_j = 25 °C - Enables <4.9 A continuous conduction with ≤2.4 W conduction loss at room temperature.
Q_g typ	17 nC - Reduces gate drive power and enables >100 kHz switching in compact flyback and LLC designs.
E_AS	215 mJ - Supports single-pulse avalanche survival under transient overvoltage events in unclamped inductive loads.
R_thJC	1.5 K/W - Allows 4.9 A operation at T_C = 100 °C with ≤7.4 °C junction rise above case.
t_rr	260 ns - Limits diode switching loss and EMI generation during hard commutation in bridge legs.
I_D,pulse	20 A - Sustains short-duration surge currents during startup or overload without bondwire failure.

Pinout & Package

IPD50R399CPATMA1 uses the PG-TO252 (DPAK) surface-mount package with exposed drain pad for thermal enhancement. The package measures 6.5 mm × 6.2 mm × 2.3 mm and supports reflow soldering up to 260 °C (10 s, 1.6 mm from case).

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main power output terminal	Exposed copper pad - must be soldered to ≥6 cm² PCB copper area for thermal performance per datasheet Fig. 5.
Source	Reference node for gate drive and current sensing	Low-inductance connection critical for stable switching; ties directly to power ground plane.
Gate	Control input for channel modulation	High-impedance node requiring <35.1 Ω external series resistance to damp ringing and limit dV/dt-induced turn-on.

Key Features

Feature	Design Value
Lowest R_DS(on) × Q_g FoM	6.8 Ω·nC - Delivers best-in-class efficiency trade-off for 500–600 V SMPS applications.
Extreme dv/dt ruggedness	400 V/ns - Prevents false turn-on during high-slew-rate transients in half-bridge and phase-shifted topologies.
Industrial JEDEC qualification	Qualified per JESD22-A108 - Ensures 15-year operational reliability in 85/85 storage and 1000-cycle temperature cycling.
Halogen-free & RoHS	Pb-free lead plating - Complies with EU RoHS Directive 2011/65/EU and IPC-1752A material declaration requirements.
Enhanced body diode	t_rr = 260 ns, Q_rr = 1.9 µC - Reduces switching loss and voltage overshoot in freewheeling paths versus standard SJ-MOSFETs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar superjunction MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP55NF06L	60 V V_BR(DSS), 55 A I_D, TO-220 - Not voltage-compatible; unsuitable for 400 V DC link.	Designed for low-voltage motor drives, not SMPS or PFC.	Select only for ≤60 V systems requiring higher current; not a functional substitute.
IPP60R099C7	650 V V_BR(DSS), 0.099 Ω R_DS(on), 63 nC Q_g, TO-220 - Higher conduction loss margin but 3.7× higher gate charge.	Better for high-power continuous conduction mode (CCM) PFC where switching loss is secondary.	Prefer when system prioritizes R_DS(on) over switching speed; requires stronger gate driver.

Compared with STP55NF06L and IPP60R099C7, IPD50R399CPATMA1 uniquely balances 550 V rating, ultra-low Q_g, and industrial thermal robustness - making it optimal for space-constrained, high-frequency DCM PFC and TV SMPS where gate drive loss and dv/dt immunity are critical.

FAQ

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

The IPD50R399CPATMA1 supports 6 A continuous drain current at T_C = 100 °C, as specified in the "Maximum ratings" table on page 1 of the Rev. 2.3 datasheet. This value is derived from derating the 9 A rating at 25 °C using the thermal resistance R_thJC = 1.5 K/W and maximum junction temperature of 150 °C.

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

No - the IPD50R399CPATMA1 has a gate threshold voltage V_GS(th) of 2.5–3.5 V and is fully controllable with 0 V to +10 V gate drive. A negative gate voltage is not required; however, pulling the gate to –5 V improves noise immunity in high-dv/dt environments per application note AN2015-05.

Can it replace IPD50R399CP in existing designs without layout changes?

Yes - IPD50R399CPATMA1 is the tape-and-reel variant of IPD50R399CP in identical PG-TO252 package with same marking "5R399P", pinout, and electrical specifications. No PCB or schematic modifications are needed for drop-in replacement in automated assembly lines.

What is the recommended gate resistor value for 100 kHz operation?

A 35.1 Ω external gate resistor is specified in the datasheet (page 3, dynamic test conditions) to achieve optimal switching behavior at 100 kHz with V_DD = 400 V and I_D = 4.9 A. This value balances turn-on speed, ringing suppression, and gate driver power dissipation in typical SMPS layouts.
