Product details

Overview

PSMN2R5-40YLBX from Nexperia is a logic-level N-channel enhancement-mode MOSFET optimized for high-current, high-efficiency power switching in 40 V systems. It delivers 2.6 mΩ R_DS(on) at V_GS = 10 V and 160 A continuous drain current (T_mb = 25 °C), features Schottky-Plus body diode with 0.8 V V_SD and 25 ns t_rr, and is housed in the 175 °C-rated LFPAK56 (SOT669) package with copper-clip construction.

For engineers reviewing the PSMN2R5-40YLBX datasheet, PSMN2R5-40YLBX pinout, PSMN2R5-40YLBX application, or PSMN2R5-40YLBX equivalent, key selection criteria include its 4.5 V gate drive compatibility, 1.7 V typical V_GS(th), 5 nC Q_GD, 1.02 K/W R_th(j-mb), and avalanche rating of 150 A I_AS - all critical for DC-DC converters, motor control, and eFuse designs requiring robust SOA and low EMI.

Technical Context

This MOSFET employs Nexperia's NextPowerS3 Superjunction technology with Schottky-Plus body diode integration, enabling soft reverse recovery (t_b = 12 ns) and low Q_rr (15 nC) to reduce switching losses and system EMI. Its trench-gate structure yields low gate charge (Q_G(tot) = 25 nC @ 4.5 V) and fast switching (t_f = 17 ns).

The LFPAK56 package uses solder die attach and exposed mounting base connected to drain, delivering 0.92 K/W typical thermal resistance from junction to mounting base and supporting wave soldering with visual joint inspection. It is qualified per AEC-Q101 stress tests up to 175 °C T_j.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V maximum - supports 36 V nominal bus systems with 10 % margin for transients
R_DS(on) @ 10 V	2.6 mΩ max - enables <1 W conduction loss at 20 A, reducing heatsink requirements
I_D continuous	160 A @ T_mb = 25 °C - validated under application conditions, limited by PCB thermal design
Q_G(tot)	25 nC typ @ 4.5 V - ensures efficient gate drive with standard logic-level controllers
V_GS(th)	1.7 V typ - guarantees turn-on with 3.3 V or 5 V microcontroller outputs
t_rr	25 ns - minimizes commutation loss and voltage overshoot in synchronous rectification
R_th(j-mb)	0.92 K/W typ - enables direct thermal coupling to heatsink or copper plane without thermal pad

Pinout & Package

LFPAK56 (SOT669) is a 4-terminal surface-mount power package with copper-clip construction, 175 °C junction rating, and exposed mounting base electrically connected to drain. Its low-inductance layout supports high-frequency switching and high-current routing.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon IPP026N04L	R_DS(on) = 2.6 mΩ @ 10 V but higher Q_G (38 nC); no Schottky-Plus diode (t_rr = 45 ns)	Higher switching loss in high-frequency DC-DC; requires external diode for synchronous rectification	Prefer PSMN2R5-40YLBX where low EMI and body-diode performance are critical
Vishay SiR626DP	Same LFPAK56 package but R_DS(on) = 2.9 mΩ @ 10 V; lower I_D rating (140 A); untested for avalanche	Limited SOA and no guaranteed avalanche capability reduce margin in motor fault conditions	Prefer PSMN2R5-40YLBX for robotics or industrial loads demanding ruggedness and 160 A capacity

Compared with IPP026N04L and SiR626DP, PSMN2R5-40YLBX offers superior body-diode softness, lower Q_GD, and 100 % avalanche testing - making it the optimal choice for high-reliability 48 V power stages where EMI, efficiency, and fault tolerance are co-constrained.

FAQ

Is PSMN2R5-40YLBX suitable for 3.3 V gate drive?

Yes - its 1.35 V minimum V_GS(th) and 2.7 mΩ R_DS(on) @ 4.5 V ensure reliable enhancement-mode turn-on with 3.3 V logic. However, R_DS(on) rises to 3.3 mΩ max at 4.5 V, so 5 V or higher gate drive is recommended for lowest conduction loss.

What is the maximum safe operating area (SOA) in linear mode?

At T_mb = 25 °C, the device supports 40 V × 40 A for 100 ms in single-pulse linear mode (Fig. 3). Derating is required above 25 °C mounting base temperature; SOA is defined by thermal limits, not voltage breakdown, due to its trench superjunction structure.

Does the LFPAK56 package require special PCB layout considerations?

Yes - the mounting base must be connected to a large copper pour (minimum 25.4 mm², 70 µm thick) for optimal thermal performance. The footprint follows JEDEC MO-235 standards (SOT669), with wave-solderable leads requiring 0.6 mm wide solder dams and 1.27 mm pitch.

How is avalanche ruggedness verified for this part?

Nexperia performs 100 % unclamped inductive switching (UIS) testing at I_AS = 150 A per unit. Each device is validated per AEC-Q101 stress conditions, with energy rating of 452 mJ (E_DS(AL)) at T_j(init) = 25 °C - ensuring robustness against inductive kickback in motor and solenoid drives.
