Product details

Overview

PSMN1R0-40ULDX from Nexperia is a logic-level N-channel enhancement-mode MOSFET in LFPAK56-UL2595 (SOT1023A) package, rated for 40 V V_DS, 1.1 mΩ R_DS(on) at V_GS = 4.5 V and 25 A, 280 A continuous drain current capability, and qualified to 150 °C junction temperature. It delivers high-efficiency power switching in UL2595-compliant battery-powered motor drives with Schottky-Plus body diode and NextPower-S3 Superjunction technology.

For engineers reviewing the PSMN1R0-40ULDX datasheet, PSMN1R0-40ULDX pinout, PSMN1R0-40ULDX application, or PSMN1R0-40ULDX equivalent, key selection criteria include its 4.5 V gate drive compatibility, 17 nC Q_GD, 59 nC Q_G(tot) at 4.5 V, 48 ns t_rr, and UL2595-enhanced creepage/clearance in SOT1023A.

Technical Context

This MOSFET employs TrenchMOS Superjunction architecture with Schottky-Plus body diode integration, enabling soft reverse recovery (t_r_r = 48 ns, Q_r = 67 nC) without elevated I_DSS. Its gate threshold voltage (V_GS(th) = 1.05–2.2 V) and low Q_G/Q_GD ratio support fast, low-EMI switching under 4.5 V logic-level drive.

The SOT1023A package features copper-clip construction, solder die attach, exposed mounting base connected to drain, and optimized thermal path yielding R_th(j-mb) = 0.66–0.76 K/W - enabling high-current operation with minimal thermal derating up to T_mb = 100 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum blocking voltage compatible with 36 V nominal battery systems and 48 V industrial rails.
R_DS(on)	1.1 mΩ @ V_GS = 4.5 V, T_j = 25 °C - Enables <1 W conduction loss at 30 A, critical for high-current motor phase legs.
I_D cont	280 A - Demonstrated continuous current capability with proper PCB thermal design and mounting base cooling.
Q_G(tot)	59 nC @ V_GS = 4.5 V - Low gate charge enables efficient 100+ kHz PWM control with standard gate drivers.
t_r_r	48 ns - Fast, soft reverse recovery minimizes voltage overshoot and EMI in H-bridge freewheeling paths.
R_th(j-mb)	0.66 K/W - Low junction-to-mounting-base thermal resistance supports >150 W power dissipation with moderate heatsinking.
V_GS(th)	1.7 V typical - Ensures reliable turn-on with 3.3 V or 5 V microcontroller GPIOs without level-shifting.

Pinout & Package

LFPAK56-UL2595 (SOT1023A) is a 4-lead surface-mount package with copper-clip construction, solder die attach, and exposed mounting base (drain-connected) for low-inductance, high-current routing and visual solder-joint inspection.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Source (S)	Three parallel source terminals reduce source inductance and enable high-current return path routing in motor gate drivers.
4	Gate (G)	Single gate input with low RG (1.3 Ω) for stable, dV/dt-immune switching and reduced ringing risk.
Mounting Base (mb)	Drain (D)	Exposed copper base electrically connected to drain - serves as primary high-current output and thermal interface to PCB/heatsink.

Key Features

Feature	Design Value

IC Role / Device Role / Timing Role: Main power switch in low-side and high-side positions, handling bidirectional 200+ A peak currents during stall and acceleration.

Use Value: 1.1 mΩ R_DS(on) reduces conduction loss by >30% vs. legacy 2.5 mΩ MOSFETs, extending runtime and reducing thermal stress on PCB copper.

Use Scenario: Battery pack protection and main power switching in UL2595-listed portable power tools.

IC Role / Device Role / Timing Role: Primary load switch and overcurrent interrupt device, leveraging avalanche rating (IAS = 190 A) for fault energy absorption.

Use Value: UL2595-compliant creepage ensures certification compliance without additional isolation barriers, simplifying mechanical design and reducing BOM cost.

BLDC Inverter Phase Leg

High-Power Portable Medical Devices

Use Scenario: 3-phase inverter stage in battery-powered e-bike controllers operating at 48 V nominal.

IC Role / Device Role / Timing Role: Low-side switch in each phase leg, commutated at 20–50 kHz with synchronous rectification.

Use Value: 48 ns t_r_r and soft recovery minimize voltage spikes across motor windings, eliminating need for external RC snubbers and reducing system EMI filtering.

Use Scenario: Isolated power delivery and patient-connected load switching in portable ultrasound or infusion pumps.

IC Role / Device Role / Timing Role: Safety-critical power enable/disable switch downstream of isolated DC/DC converter, requiring certified creepage and low leakage.

Use Value: <1 µA I_DSS at 125 °C and UL2595 spacing ensure safe, predictable behavior in life-support-adjacent applications where leakage-induced false triggers are unacceptable.

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
PSMN1R0-40YLD	Same die, SOT78 (TO-220FP) package - no UL2595 creepage enhancements, higher R_th(j-a) (125 K/W), no mounting base.	Used in non-UL2595 applications where through-hole mounting or lower-cost packaging is acceptable.	Select when UL certification is unnecessary and thermal path relies on ambient convection rather than mounting base conduction.
IPB011N04LG	Infineon OptiMOS 5, 40 V, 0.95 mΩ @ 10 V, 240 A, PG-HSOF-8 package - higher gate charge (72 nC), no Schottky-Plus diode.	Targeted at high-frequency SMPS, not motor control - lacks soft-recovery diode and UL2595 compliance.	Choose only if prioritizing lowest R_DS(on) at 10 V drive and system operates above 100 kHz with strict EMI limits but no safety spacing requirements.

Compared with PSMN1R0-40YLD, this part trades package cost and mounting flexibility for UL2595 compliance and superior thermal performance via the mounting base; compared with IPB011N04LG, it sacrifices marginal R_DS(on) improvement for essential soft-recovery and safety-certified layout.

FAQ

What is the maximum continuous drain current for PSMN1R0-40ULDX under real-world PCB conditions?

The datasheet specifies 280 A continuous current demonstrated in application tests, but practical current is limited by PCB copper area, thermal vias, heatsinking, and mounting base temperature. At T_mb = 100 °C, the rated continuous current drops to 198 A per Figure 2. Designers must validate thermal performance using the provided R_th(j-mb) = 0.66 K/W and derating curves.

Does PSMN1R0-40ULDX require a gate resistor for stability in motor drive applications?

Yes - although its intrinsic gate resistance is low (1.3 Ω), a series gate resistor (typically 2.2–10 Ω) is required to dampen ringing caused by PCB trace inductance and prevent spurious turn-on due to high dV/dt. The 17 nC Q_GD and 59 nC Q_G(tot) values inform optimal resistor selection to balance switching speed and EMI.

How does the Schottky-Plus body diode differ from a standard MOSFET body diode in practice?

The Schottky-Plus structure delivers soft reverse recovery (t_r_r = 48 ns, Q_r = 67 nC) with minimal tail current, reducing voltage overshoot and EMI during freewheeling. Unlike standard body diodes, it maintains low I_DSS (<1 µA at 125 °C), avoiding thermal runaway risks in high-temperature motor control environments.

Can PSMN1R0-40ULDX be used in parallel configurations for >280 A applications?

Yes - its positive temperature coefficient for R_DS(on) (see Figure 11) enables inherent current sharing when paralleled. However, layout symmetry (equal gate and source inductance per device), matched gate drive timing, and thermal coupling must be strictly maintained. Derating to ≤220 A per device is recommended for long-term reliability in parallel use.
