Product details

Overview

PSMN1R5-50YLHX from Nexperia is a logic-level N-channel enhancement-mode MOSFET in LFPAK56E (SOT1023) package, rated for 50 V V_DS, 1.7 mΩ R_DS(on) @ 10 V, 200 A continuous drain current, and qualified to 175 °C junction temperature. It delivers high-efficiency switching in battery isolation and DC motor control circuits, especially in 36 V nominal lithium-ion systems with demanding avalanche and linear-mode requirements.

For engineers reviewing the PSMN1R5-50YLHX datasheet, PSMN1R5-50YLHX pinout, PSMN1R5-50YLHX application, or PSMN1R5-50YLHX equivalent, key selection criteria include its SchottkyPlus body-diode performance, low Q_G/Q_GD for high-frequency operation, 100% avalanche-tested ruggedness, and narrow V_GS(th) distribution enabling reliable paralleling in high-current load-switch designs.

Technical Context

This MOSFET employs Nexperia's SchottkyPlus technology-achieving soft, low-spiking body-diode recovery (t_rr = 36 ns, Q_r = 37 nC) without elevated I_DSS leakage (≤3.9 µA @ 125 °C). Its copper-clip die attach and exposed mounting base yield R_th(j-mb) = 0.33 K/W and support 333 W total power dissipation at T_mb = 25 °C.

The device is optimized for 36 V battery systems (e.g., 10-cell Li-ion), featuring strong SOA up to 200 A at V_DS ≤ 8 V, 100% unclamped avalanche testing (E_AS = 2 J @ 25 A), and gate threshold voltage tightly distributed between 1.2 V and 2.2 V for consistent turn-on behavior across temperature and parallel configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	50 V - Maximum drain-source blocking voltage compatible with 36 V nominal battery systems with headroom for transients.
R_DS(on)	1.4–1.75 mΩ @ V_GS = 10 V, T_j = 25 °C - Enables <100 mW conduction loss at 25 A, critical for high-efficiency BMS and motor drive stages.
I_D (cont)	200 A @ T_mb = 25 °C - Validated continuous current capability, limited in practice by PCB thermal design and mounting base temperature.
Q_G(tot)	53–82 nC @ V_GS = 4.5 V - Low gate charge supports efficient 100+ kHz switching in synchronous rectifiers and load switches.
E_AS	2 J @ I_D = 25 A, V_sup ≤ 50 V - 100% tested non-repetitive avalanche energy ensures robustness against inductive switching faults.
t_rr	36 ns - Fast, soft reverse recovery minimizes voltage overshoot and EMI in high-dV/dt applications like BLDC inverters.
R_th(j-mb)	0.33 K/W - Ultra-low junction-to-mounting-base thermal resistance enables direct heatsink attachment and high-power density layout.

Pinout & Package

LFPAK56E (SOT1023) is a low-stress, copper-clip-based surface-mount package with an exposed mounting base connected to drain, optimized for solder-joint inspection, thermal performance, and mechanical reliability under thermal cycling.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Source (S)	Three parallel source terminals reduce package inductance and improve current sharing in high-di/dt switching.
4	Gate (G)	Single gate input with low RG (0.52–3.3 Ω) for stable, fast turn-on/turn-off control using standard logic-level drivers.
Mounting Base (mb)	Drain (D)	Exposed copper pad electrically and thermally connected to drain; serves as primary heat path and high-current return node.

Key Features

Feature	Design Value
SchottkyPlus body diode	Soft recovery (t_a = 21 ns, t_b = 14 ns) and low Q_r = 37 nC enable low-EMI synchronous rectification without Schottky leakage penalty.
Narrow V_GS(th)	1.2–2.2 V range at 25 °C ensures uniform turn-on timing and predictable current sharing when paralleled in high-current load switches.
Strong linear-mode SOA	Rated for safe operation up to 200 A at V_DS ≤ 8 V - supports robust battery protection during short-circuit or inrush events.
100% avalanche tested	Each unit validated for unclamped inductive switching (IAS = 115 A, E_AS = 2 J), eliminating need for external snubbers in motor control.
LFPAK56E construction	Copper-clip die attach and exposed drain pad deliver 0.33 K/W thermal resistance and <1 nH package inductance for high-frequency stability.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon IPP026N04L	40 V V_DS, 2.6 mΩ R_DS(on) @ 10 V, TO-220 package, no avalanche rating	Limited to ≤40 V systems; lacks 100% avalanche test and SchottkyPlus diode performance	Choose only if 40 V rating suffices and TO-220 thermal mounting is preferred over surface-mount LFPAK56E.
Vishay SiR626DP	60 V V_DS, 2.1 mΩ R_DS(on) @ 10 V, PowerPAK 8×8, Q_G = 102 nC (higher switching loss)	Higher voltage margin but higher gate charge increases driver stress and reduces efficiency above 100 kHz	Select when 60 V headroom is mandatory and switching frequency remains below 50 kHz; avoid for high-frequency BMS or BLDC.

Compared with IPP026N04L and SiR626DP, PSMN1R5-50YLHX uniquely combines 50 V rating, sub-2 mΩ on-resistance, ultra-low Q_G, and SchottkyPlus diode behavior in a surface-mount package-making it optimal for space-constrained, high-frequency, high-reliability 36 V battery and motor systems where avalanche robustness and EMI control are critical.

FAQ

What is the maximum continuous drain current for PSMN1R5-50YLHX, and what limits it in practice?

The datasheet specifies 200 A continuous drain current at T_mb = 25 °C, validated in application testing. In real designs, this current is limited by PCB copper area, thermal interface to heatsink, ambient temperature, and mounting base temperature-not by the silicon itself. Derating begins above T_mb = 25 °C per Fig. 2, reaching ~100 A at T_mb = 100 °C.

How does SchottkyPlus technology differ from a standard MOSFET body diode or integrated Schottky diode?

SchottkyPlus delivers Schottky-like soft reverse recovery (t_rr = 36 ns, Q_r = 37 nC) and low spiking without the high reverse leakage (I_DSS) typical of integrated Schottky diodes. At 125 °C, I_DSS remains ≤3.9 µA-over 10× lower than comparable Schottky-integrated MOSFETs-enabling reliable operation in thermally demanding BMS and motor control environments.

Can PSMN1R5-50YLHX be paralleled with identical units, and what design considerations apply?

Yes-its narrow V_GS(th) distribution (1.2–2.2 V) and low R_DS(on) temperature coefficient ensure balanced current sharing. Use matched gate resistors (≤5 Ω), symmetrical PCB layout, and common-source routing. Avoid mixing batches unless V_GS(th) screening is performed; thermal coupling via shared heatsink further improves balance.

Is PSMN1R5-50YLHX suitable for linear-mode (SOA) operation, and what are its safe operating limits?

Yes-it is explicitly characterized for linear-mode use with strong SOA up to 200 A at V_DS ≤ 8 V (Fig. 3). Safe operation requires strict thermal management: junction temperature must stay ≤175 °C, and power dissipation must remain within the derated P_tot curve (Fig. 1). For 100 A at 5 V, T_mb must be ≤65 °C to maintain reliability.
