Product details

Overview

IPTC044N15NM5 from Infineon Technologies is an N-channel enhancement-mode MOSFET optimized for high-efficiency 150 V power conversion, featuring 4.4 mΩ max R_DS(on), 174 A continuous drain current at T_C = 25 °C, and 100% avalanche-tested ruggedness in PG-HDSOP-16 package. It serves as a primary switching device in industrial DC-DC converters, motor drives, and UPS inverters where low conduction loss and robust thermal performance are critical.

For engineers reviewing the IPTC044N15NM5 datasheet, IPTC044N15NM5 pinout, IPTC044N15NM5 application, or IPTC044N15NM5 equivalent, key selection criteria include its 0.5 °C/W junction-to-case thermal resistance, 71 nC total gate charge, 200 nC output charge, and validated operation up to 175 °C junction temperature in industrial-grade systems.

Technical Context

This OptiMOSTM 5-generation MOSFET employs trench-gate superjunction technology to achieve ultra-low R_DS(on) while maintaining fast switching with 17 ns turn-on delay and 25 ns turn-off delay at V_DD = 75 V, I_D = 50 A. Its gate plateau voltage of 5.4 V ensures stable Miller region control during hard-switching transitions.

The integrated body diode delivers 45–91 ns reverse recovery time and 49–98 nC Q_rr under 75 V reverse bias and 100 A/µs di/dt, enabling efficient synchronous rectification and freewheeling in half-bridge topologies without external Schottky supplementation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current 150 V MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N15F7AG	Higher R_DS(on) (5.2 mΩ), lower Q_g (58 nC), same PG-HSOP-16 package	Better suited for higher-frequency (>200 kHz) soft-switching where gate loss dominates	Select when prioritizing gate drive efficiency over conduction loss in resonant topologies.
IXFH44N15X3	TO-247-3L package, higher R_thJC (0.75 °C/W), 4.8 mΩ R_DS(on), 100 V avalanche rating only	Requires bolt-down heatsinking; not suitable for space-constrained SMT-only designs	Choose only if existing TO-247 thermal infrastructure exists and board area permits larger footprint.

Compared with STL220N15F7AG and IXFH44N15X3, IPTC044N15NM5 delivers the lowest R_DS(on) in SMT form factor with verified 150 V avalanche capability-making it optimal for thermally dense industrial inverters where conduction loss and ruggedness are primary constraints.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The IPTC044N15NM5 is rated for continuous operation up to T_j = 175 °C, as confirmed in Table 2 of the Rev. 2.1 datasheet. Derating curves in Diagram 2 show that ID remains ≥115 A at T_C = 100 °C, supporting reliable operation in sealed enclosures with limited airflow.

Is this MOSFET suitable for use in synchronous rectification circuits?

Yes-the integrated body diode has characterized t_rr = 45–91 ns and Q_rr = 49–98 nC at 75 V and 100 A/µs di/dt, enabling efficient synchronous rectification in LLC and phase-shifted full-bridge converters without external diode replacement.

Does the PG-HDSOP-16 package require solder paste stencil modifications?

Yes-the exposed drain tab (Pins 9–16 + metal pad) demands a 0.15 mm thick stencil with 75 % aperture fill ratio to ensure void-free thermal pad soldering. IPC-7351B land pattern DSO-16-17 is recommended for optimal thermal and mechanical reliability.

How does the 100% avalanche testing impact field reliability?

Each unit undergoes single-pulse avalanche stress at E_AS = 321 mJ, verifying robustness against inductive turn-off transients. This eliminates latent infant mortality failures in motor drive and UPS applications where unclamped inductive spikes commonly occur.
