Product details

Overview

IPD50R399CPBTMA1 from Infineon Technologies is a 550 V, 0.399 Ω R_DS(on) CoolMOS™ CP superjunction power MOSFET in PG-TO252 (DPAK) package, optimized for hard/soft-switching SMPS and DCM PFC in lamp ballasts and LCD/PDP TVs. It delivers 9 A continuous drain current at T_C = 25 °C, 17 nC typical gate charge, and 215 mJ single-pulse avalanche energy.

For engineers reviewing the IPD50R399CPBTMA1 datasheet, IPD50R399CPBTMA1 pinout, IPD50R399CPBTMA1 application, or IPD50R399CPBTMA1 equivalent, key selection criteria include R_DS(on) × Q_g figure of merit, dv/dt ruggedness (400 V/ns), reverse diode recovery performance (t_rr = 260 ns), and thermal resistance (R_thJC = 1.5 K/W).

Technical Context

This 550 V superjunction MOSFET employs charge compensation technology to achieve ultra-low R_DS(on) × Q_g (≈6.8 Ω·nC), enabling high-efficiency switching in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) topologies. Its 2.5–3.5 V gate threshold voltage ensures robust noise immunity while supporting standard 10 V gate drive.

The integrated body diode features low forward voltage (V_SD = 0.9–1.2 V @ 4.9 A) and controlled reverse recovery (Q_rr = 1.9 µC, I_rrm = 12.2 A), reducing switching losses in bridge-leg and synchronous rectification configurations. Thermal design is supported by 1.5 K/W junction-to-case resistance and JEDEC-qualified reliability for industrial lighting and consumer power supplies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	550 V - supports 400 V DC-link designs with 25% margin for voltage transients
R_DS(on) max	0.399 Ω @ T_j = 25 °C - enables <9 A continuous operation at T_C = 25 °C with ≤4.9 W conduction loss
Q_g typ	17 nC - reduces gate drive power and enables >100 kHz switching with low driver stress
E_AS	215 mJ - withstands single-pulse avalanche events without failure under 50 V clamp conditions
dv/dt rating	400 V/ns - prevents spurious turn-on in high-di/dt environments like PFC boost stages
R_thJC	1.5 K/W - allows 83 W power dissipation at T_C = 25 °C before reaching T_jmax = 150 °C
t_rr	260 ns - limits reverse recovery loss in half-bridge and LLC resonant converters

Pinout & Package

IPD50R399CPBTMA1 is housed in PG-TO252 (DPAK) package with exposed drain pad for thermal enhancement. Pin assignment follows standard 3-terminal TO252 layout: Drain (tab), Source (pin 1), Gate (pin 2).

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path collector	Electrically connected to heatsink; requires insulated mounting or thermal pad for PCB thermal management
Source (Pin 1)	Reference node for gate drive and current sensing	Serves as return path for load current and gate drive loop; critical for minimizing common-source inductance
Gate (Pin 2)	Control terminal for channel modulation	High-impedance input requiring low-inductance routing; gate resistor selection affects switching speed and EMI

Key Features

Feature	Design Value
Lowest R_DS(on) × Q_g	≈6.8 Ω·nC - enables highest efficiency in high-frequency SMPS without sacrificing gate drive simplicity
Extreme dv/dt ruggedness	400 V/ns - eliminates need for external snubbers in fast-switching PFC and resonant converters
High peak current capability	I_D,pulse = 20 A - supports surge handling during startup and overload in TV backlight inverters
JEDEC-qualified reliability	J-STD-20/JESD22 compliant - validated for long-term operation in lamp ballast and consumer display applications
RoHS-compliant plating	Pb-free lead finish - meets global environmental regulations without compromising solderability or wire-bond reliability

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
IPD50R400CEXTMA1	R_DS(on) max = 0.400 Ω, Q_g = 16.5 nC, same PG-TO252 package	Optimized for lower gate charge in high-frequency PFC; identical thermal footprint	Select when prioritizing minimal gate drive loss over marginal R_DS(on) reduction
IPP50R399CP	Same R_DS(on) and Q_g	PG-TO220 package with higher R_thJC (1.0 K/W) and larger board area	Choose for legacy designs requiring TO220 mechanical compatibility and higher power dissipation headroom

Compared with IPD50R399CPBTMA1, IPD50R400CEXTMA1 offers slightly lower Q_g for improved high-frequency efficiency but no R_DS(on) advantage, while IPP50R399CP trades compact DPAK size for greater thermal mass and easier heatsinking in space-tolerant industrial layouts.

FAQ

What is the maximum continuous drain current at T_C = 100 °C?

The IPD50R399CPBTMA1 supports 6 A continuous drain current at case temperature of 100 °C, derated from 9 A at 25 °C per the thermal resistance curve and SOA limitations. This value accounts for increased R_DS(on) at elevated junction temperatures and ensures safe operation within the 150 °C maximum junction temperature limit.

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

No, the IPD50R399CPBTMA1 does not require negative gate drive. Its gate threshold voltage (2.5–3.5 V) and positive-only gate-source voltage rating (±20 V) allow reliable turn-off with 0 V gate bias. Negative voltage is unnecessary due to its high dv/dt immunity and low gate leakage (<100 nA).

How does the body diode performance compare to standard silicon MOSFETs?

The integrated body diode exhibits t_rr = 260 ns, Q_rr = 1.9 µC, and V_SD = 0.9–1.2 V at 4.9 A, significantly faster and lower-loss than conventional planar MOSFET diodes. This results from optimized charge compensation structure, enabling reduced reverse recovery loss in hard-switched bridge configurations.

Is the PG-TO252 package lead-free and RoHS-compliant?

Yes, the IPD50R399CPBTMA1 uses Pb-free lead plating and is fully RoHS-compliant per EU Directive 2011/65/EU. The device passes J-STD-020 reflow profile requirements, including peak soldering temperature of 260 °C for 10 seconds at 1.6 mm from case, ensuring compatibility with standard lead-free assembly processes.
