Product details

Overview

PSMN038-100YL from Nexperia is an N-channel 100 V, 37.5 mΩ logic-level MOSFET in LFPAK56 (SOT669) package, designed for high-efficiency switching in DC-DC converters and load-switch applications. It delivers 30 A continuous drain current at T_mb = 25 °C, supports gate drive down to 5 V, and is qualified to 175 °C junction temperature.

For engineers reviewing the PSMN038-100YL datasheet, PSMN038-100YL pinout, PSMN038-100YL application, or PSMN038-100YL equivalent, key selection criteria include R_DS(on) at 5 V and 10 V gate drive, avalanche energy rating (45.1 mJ), thermal resistance (1.44 K/W), and LFPAK56 footprint compatibility with Power-SO8 layouts.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(on) and fast switching with minimal gate charge (Q_G(tot) = 21.6 nC at V_GS = 5 V). Its logic-level gate threshold (V_GS(th) = 1.4–2.1 V typ at 25 °C) enables direct drive from 3.3 V and 5 V microcontrollers without level-shifting.

The device integrates a robust body diode with 31 ns reverse recovery time and 44 nC recovered charge, supporting synchronous rectification and freewheeling in hard-switched topologies. Thermal design is enabled by its low R_th(j-mb) of 1.44 K/W and mounting-base (drain-connected) thermal path.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Maximum blocking voltage for use in 48 V input DC-DC stages and TV power supplies
R_DS(on)	37.5 mΩ max at V_GS = 10 V, T_j = 25 °C - Enables <1.9 W conduction loss at 7 A continuous current
I_D	30 A continuous at T_mb = 25 °C - Supports high-current load switching with adequate PCB copper area
Q_G(tot)	21.6 nC typ at V_GS = 5 V - Low gate charge reduces driver power and enables efficient 500 kHz+ switching
E_AS	45.1 mJ non-repetitive avalanche energy - Withstands unclamped inductive turn-off transients up to 30 A
R_th(j-mb)	1.44 K/W typ - Allows >90 W power dissipation with 130 °C ΔT between junction and mounting base
V_GS(th)	1.7 V typ at 25 °C - Ensures reliable turn-on with 3.3 V logic outputs and margin at elevated temperature

Pinout & Package

LFPAK56 (SOT669) is a 4-lead surface-mount plastic package with exposed mounting base connected to drain. It provides enhanced thermal performance over SO-8 and footprint compatibility with legacy Power-SO8 designs.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Source	Three parallel source terminals reduce source inductance and improve current sharing in high-di/dt switching
4	Gate	Single gate input with 1.64 Ω internal gate resistance - simplifies external gate resistor selection
Mounting base	Drain	Exposed copper pad electrically and thermally connected to drain - primary heat transfer path to PCB

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced with V_GS ≥ 5 V - eliminates need for gate driver ICs in 3.3 V/5 V control systems
LFPAK56 thermal performance	R_th(j-mb) = 1.44 K/W - delivers 2× higher power density than standard SO-8 equivalents
Avalanche ruggedness	E_AS = 45.1 mJ - withstands worst-case inductive turn-off without external snubbers in DC-DC and motor drives
High-temperature qualification	Rated for 175 °C operation - suitable for sealed industrial enclosures and automotive under-hood proximity
Power-SO8 footprint compatibility	SOT669 outline matches SO-8 land pattern - enables drop-in upgrade from older MOSFETs without PCB redesign

Applications

DC-DC Converters

Load Switch

Use Scenario: Synchronous buck converter in telecom power modules delivering 12 V @ 20 A from 48 V input.

IC Role / Device Role / Timing Role: High-side switch with 500 kHz PWM, driven directly by controller's 5 V gate output.

Use Value: 37.5 mΩ R_DS(on) limits conduction loss to 15 W at full load; low Q_G minimizes switching loss and EMI.

Use Scenario: Hot-swap power rail enable for FPGA I/O bank requiring inrush current limiting and fault protection.

IC Role / Device Role / Timing Role: Low-side load switch controlled by system supervisor IC with open-drain 3.3 V output.

Use Value: Logic-level V_GS(th) ensures clean turn-on at 3.3 V; 120 A peak current rating handles startup surges.

TV Power Supplies

Industrial Motor Drives

Use Scenario: PFC front-end and main DC bus switching in 200 W LED-backlit LCD TV power supply.

IC Role / Device Role / Timing Role: Boost switch in continuous conduction mode (CCM) PFC stage operating at 65 kHz.

Use Value: 100 V rating accommodates 400 V DC bus with margin; 45.1 mJ avalanche rating absorbs line surge events.

Use Scenario: Half-bridge leg in 24 V BLDC motor controller for HVAC blowers and industrial fans.

IC Role / Device Role / Timing Role: Low-side switch in 20 kHz PWM-driven inverter, commutated with body diode freewheeling.

Use Value: 31 ns t_rr and 44 nC Q_r minimize diode recovery losses; 175 °C rating supports enclosed motor housing temps.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
PSMN022-100YL	Lower R_DS(on) (22 mΩ typ), higher Q_G (39.2 nC), same V_DS and package	Better conduction efficiency but higher gate drive loss above 300 kHz	Select when thermal headroom is limited and switching frequency ≤ 200 kHz
IRF7470PBF	SO-8 package, 40 mΩ R_DS(on), 25 nC Q_G, 100 V rating, not 175 °C qualified	Limited to 150 °C operation; no avalanche rating specified	Acceptable for cost-sensitive consumer applications where ambient temp < 85 °C

Compared with PSMN038-100YL, PSMN022-100YL trades higher gate charge for lower conduction loss, while IRF7470PBF sacrifices temperature rating and ruggedness for SO-8 compatibility and lower unit cost - making PSMN038-100YL optimal for thermally constrained industrial designs requiring reliability at 175 °C.

FAQ

What is the maximum continuous drain current for PSMN038-100YL at 100 °C mounting base temperature?

At T_mb = 100 °C, the continuous drain current is 21.3 A (per Table 5, Limiting Values). This derating reflects thermal constraints of the LFPAK56 package and must be verified against actual PCB copper area and airflow in the target application.

Does PSMN038-100YL have a specified reverse recovery time for its integrated body diode?

Yes - the source-drain diode has t_rr = 31 ns and Q_r = 44 nC at I_S = 10 A, dI_S/dt = −100 A/µs, V_DS = 25 V, and T_j = 25 °C (Table 10). These values support synchronous rectification and freewheeling in hard-switched converters.

Can PSMN038-100YL be used in avalanche-mode operation, and what is its rated energy?

Yes - it is rated for non-repetitive drain-source avalanche energy E_AS = 45.1 mJ under specified conditions (I_D = 30 A, V_sup ≤ 100 V, R_GS = 50 Ω, V_GS = 10 V, T_j(init) = 25 °C, unclamped). This enables robustness against inductive switching transients without external clamping.

Is the mounting base of PSMN038-100YL electrically isolated from the drain terminal?

No - the mounting base is internally connected to the drain (as confirmed in Table 2, Pinning Information). This requires careful PCB layout: the thermal pad must be routed to the drain net and isolated from other potentials, and solder mask opening must match the exposed copper area for optimal thermal transfer.
