Product details

Overview

IPU06N03LAGXK from Infineon Technologies is an N-channel logic-level power MOSFET in PG-TO251-3-1 package, rated for 25 V V_DS, 50 A continuous drain current at T_C = 100 °C, and 5.7 mΩ max R_DS(on) (SMD version). It delivers high-frequency switching performance in synchronous buck converters with 175 °C maximum junction temperature and JEDEC-qualified reliability.

For engineers reviewing the IPU06N03LAGXK datasheet, IPU06N03LAGXK pinout, IPU06N03LAGXK application, or IPU06N03LAGXK equivalent, key selection criteria include gate charge (Q_g = 17–22 nC), thermal resistance (R_thJC = 1.8 K/W), reverse diode forward voltage (V_SD = 0.92–1.2 V), avalanche energy (E_AS = 225 mJ), and dv/dt ruggedness (6 kV/µs).

Technical Context

This MOSFET is optimized for high-efficiency, high-frequency DC/DC conversion where low gate charge × R_DS(on) figure-of-merit (FOM) enables reduced switching and conduction losses. Its logic-level gate threshold (V_GS(th) = 1.2–2.0 V) supports direct drive from 3.3 V or 5 V controllers without level-shifting.

Thermal design is supported by a low junction-to-case resistance (1.8 K/W) and operation up to 175 °C, enabling compact heatsinking in space-constrained power stages. The integrated body diode exhibits low Q_rr (≤10 nC) and controlled reverse recovery for reduced shoot-through risk in synchronous rectification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	25 V - Maximum blocking voltage for 12 V input rail applications with margin
R_DS(on) max	5.7 mΩ (SMD version) - Enables ≤144 mW conduction loss at 60 A peak in 48 V→12 V converters
I_D continuous	50 A at T_C = 100 °C - Sustains high-current output stage operation with standard PCB cooling
Q_g	17–22 nC - Supports >1 MHz switching with moderate gate driver strength (e.g., 2 A peak)
E_AS	225 mJ - Withstands single-pulse inductive energy during hard-switching or fault events
R_thJC	1.8 K/W - Allows precise junction temperature estimation using case temperature measurement
V_GS(th)	1.2–2.0 V - Ensures full enhancement with 3.3 V microcontroller GPIO or PWM controller outputs

Pinout & Package

IPU06N03LAGXK uses the PG-TO251-3-1 (also labeled P-TO251-3-1) surface-mount package with exposed drain pad for thermal and electrical connection. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives gate drive signal; low input capacitance (C_iss = 2093–2653 pF) minimizes driver loading
Pin 2 (Drain)	High-side switch node / Power output	Exposed copper tab - must be soldered to large PCB copper area for thermal and current path integrity
Pin 3 (Source)	Reference node / Return path	Provides low-inductance source return; ties to power ground plane to reduce switching noise coupling

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced with 3.3 V or 5 V gate voltage - eliminates need for external level shifters in low-voltage control systems
Low Q_g × R_DS(on) FOM	~100–130 mΩ·nC - directly reduces total switching + conduction loss in high-frequency POL converters
175 °C rated junction temperature	Enables reliable operation in sealed enclosures or high-ambient environments without derating penalties
JEDEC-qualified reliability	Validated per J-STD-20 and JESD22 - ensures robustness for automotive and industrial production use
Low reverse recovery charge (Q_rr)	≤10 nC - suppresses voltage overshoot and EMI during synchronous FET commutation

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPD06N03LAG	Same die, PG-TO252-3-11 package - higher R_thJA (75 K/W) due to smaller thermal pad footprint	Better suited for lower-power designs (<30 A) with minimal PCB copper area	Select when board layout constraints prevent large drain pad or when cost-per-watt favors TO252 assembly
IRLHS6342TRPBF	20 V V_DS, 4.5 mΩ R_DS(on) @ 4.5 V, 30 A I_D - lower voltage rating but superior low-V_GS on-resistance	Optimized for 5 V input rails (e.g., USB PD, portable electronics), not 12/24/48 V systems	Choose only for sub-20 V applications requiring <5 mΩ at 3.3 V drive; not drop-in for 25 V designs

Compared with IPD06N03LAG and IRLHS6342TRPBF, IPU06N03LAGXK provides the best balance of 25 V rating, 50 A current capability, and TO251 thermal performance - making it optimal for industrial and telecom DC/DC where voltage margin and thermal headroom are critical.

FAQ

What is the maximum recommended gate resistor value for IPU06N03LAGXK in a 1 MHz buck converter?

A 2.7 Ω gate resistor is validated in the datasheet for 1 MHz operation with 15 V drive and 25 A load. Using ≥5 Ω increases switching time and losses; values below 1.5 Ω risk ringing and overshoot due to low gate resistance (1 Ω typ) and 2093 pF C_iss. Thermal derating applies above 100 °C case temperature.

Does IPU06N03LAGXK support synchronous rectification in continuous conduction mode (CCM)?

Yes - its low Q_rr (≤10 nC), fast diode recovery, and low V_SD (0.92–1.2 V) make it suitable for CCM synchronous rectification. Layout must minimize source inductance and ensure tight gate loop routing to avoid shoot-through during dead-time transitions.

Can IPU06N03LAGXK replace IPD06N03LAG in an existing TO252-based design?

No - although electrically identical, the PG-TO251-3-1 package has different pad layout, thermal pad geometry, and mounting hole pattern. Direct replacement requires PCB redesign to accommodate the smaller outline and single mounting tab versus TO252's dual-tab configuration.

Is the 175 °C maximum junction temperature rated for continuous operation or only short pulses?

The 175 °C rating is for continuous operation under specified thermal conditions (T_C ≤ 100 °C, proper PCB copper area). Junction temperature must be calculated using R_thJC = 1.8 K/W and actual power dissipation - sustained operation above 175 °C violates absolute maximum ratings and risks parametric drift or failure.
