Product details

Overview

IPD50R380CEATMA1 from Infineon Technologies is a 500 V, 0.38 Ω R_DS(on) CoolMOS™ CE superjunction power MOSFET in DPAK (PG-TO252) package, optimized for high-efficiency PFC and hard-switching SMPS stages in consumer and lighting applications. It delivers 14.1 A continuous drain current at T_C = 25°C, 24.8 nC total gate charge, and 2.54 µJ output energy at 400 V.

For engineers reviewing the IPD50R380CEATMA1 datasheet, IPD50R380CEATMA1 pinout, IPD50R380CEATMA1 application, or IPD50R380CEATMA1 equivalent, key selection criteria include its low FOM (R_DS(on) × Q_g), high commutation ruggedness (500 A/µs di/dt), and gate-drive simplicity with 5.3 V plateau voltage - critical for stable operation in resonant and PWM topologies.

Technical Context

This CoolMOS™ CE device implements a superjunction cell structure enabling reduced conduction and switching losses simultaneously. Its 500 V V_(BR)DSS rating, 150 °C max junction temperature, and 1.27 °C/W R_thJC support thermally constrained designs in compact adapters and LED drivers.

The MOSFET features a fast intrinsic body diode with 207 ns reverse recovery time and 1.7 µC Q_rr, validated for hard-switched PFC boost stages and LLC primary-side switching where diode performance directly impacts efficiency and EMI.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	550 V - supports 400 V DC-link designs with 25% margin against transients in offline SMPS
R_DS(on) max @ 150°C	0.38 Ω - enables low conduction loss in 14.1 A continuous operation at elevated temperature
Q_g typ	24.8 nC - determines gate drive power and switching speed in 100–500 kHz PFC controllers
E_oss @ 400 V	2.54 µJ - defines turn-off energy loss and influences snubber design in hard-switched converters
di/dt ruggedness	500 A/µs - ensures reliable operation during fast current transitions in resonant LLC circuits
V_GS(th)	2.5–3.5 V - provides clear logic-level gate control compatibility with standard 5 V or 12 V drivers
Package	DPAK (PG-TO252) - surface-mount footprint with exposed drain pad for thermal relief in PCB-constrained lighting modules

Pinout & Package

IPD50R380CEATMA1 uses the DPAK (PG-TO252) package with three terminals: Drain (Pin 2), Gate (Pin 1), and Source (Pin 3). The exposed drain pad on the underside provides low thermal resistance (1.27 °C/W) to the PCB copper pour.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control input	Receives gate drive signal; requires <3 Ω gate resistance for optimal switching and EMI control
Pin 2 (Drain)	High-voltage power output	Connected to AC/DC rectified bus or transformer primary; electrically tied to exposed metal pad for thermal conduction
Pin 3 (Source)	Power return reference	Serves as local ground reference for gate driver; must be routed with low inductance to minimize ringing

Key Features

Feature	Design Value
Low R_DS(on) × Q_g figure-of-merit	Enables >95% efficiency in 65–100 W PFC stages without active cooling
High commutation ruggedness	Withstands 500 A/µs di/dt and 50 V/ns dv/dt without failure in hard-switched boost converters
Easy gate drive	5.3 V gate plateau and 3 Ω internal gate resistance simplify driver selection and layout
Pb-free plating & halogen-free mold compound	Meets RoHS 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 (MSL1)

Applications

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, 0.95 Ω R_DS(on), 12.5 nC Q_g, TO-220FP package	Higher R_DS(on) increases conduction loss; lower Q_g eases gate drive but reduces soft-switching margin	Preferred only where cost is primary constraint and thermal headroom exceeds 25°C
IPP60R099C6	600 V, 0.099 Ω R_DS(on), 42 nC Q_g, TO-220 package	Lower R_DS(on) improves efficiency at high current, but higher Q_g demands stronger gate driver and increases EMI risk	Recommended when system operates >10 A continuous and board space allows larger package

Compared with STP5NK50ZFP and IPP60R099C6, IPD50R380CEATMA1 offers the best balance of low R_DS(on), moderate Q_g, and DPAK thermal performance - making it optimal for space-constrained, cost-sensitive lighting and adapter designs requiring ≥92% efficiency across universal input range.

FAQ

Is IPD50R380CEATMA1 suitable for paralleling in high-current PFC designs?

Yes - the datasheet explicitly recommends gate ferrite beads or separate totem-pole drivers for paralleling. Its matched threshold voltage (2.5–3.5 V) and low R_DS(on) tolerance (±10%) ensure balanced current sharing across up to four devices in interleaved PFC stages without external current-sense feedback.

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

A 3.4 Ω gate resistor is specified in the datasheet for dynamic characterization at 100 kHz. For stable operation, values between 2.2 Ω and 4.7 Ω are recommended - lower values reduce switching time but increase EMI; higher values improve EMI but raise switching loss and require verification of gate drive strength.

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

No - the device is fully compatible with 0 V to +13 V gate drive. Its V_GS rating (±30 V) and 5.3 V gate plateau allow robust operation with standard unipolar drivers. Negative turn-off is unnecessary and not recommended per Infineon's application notes for CE series.

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

It features a fast, soft-recovery body diode with 207 ns t_rr and 1.7 µC Q_rr - significantly better than standard planar MOSFETs (typically >500 ns t_rr). This reduces voltage overshoot and EMI in hard-switched topologies and enables reliable operation in quasi-resonant flyback without external snubbers.
