Product details

Overview

PMV40UN from Nexperia is an N-channel enhancement-mode TrenchMOS™ power MOSFET in SOT23 package, designed for ultra-low-threshold switching in battery-powered systems. It delivers R_DS(on) ≤ 47 mΩ at V_GS = 4.5 V, supports continuous drain current up to 4.9 A at T_sp = 25 °C, and operates with V_DS ≤ 30 V - enabling efficient load switching in portable power management circuits.

For engineers reviewing the PMV40UN datasheet, PMV40UN pinout, PMV40UN application, or PMV40UN equivalent, this page provides verified technical context, validated pin functions, real-world use cases in battery protection and high-speed logic-level switching, and confirmed alternative parts with documented parameter trade-offs.

Technical Context

This device uses TrenchMOS™ technology to achieve low gate threshold voltage (V_GS(th) = 0.45–0.7 V at T_j = 25 °C) and stable R_DS(on) across temperature - critical for direct GPIO-driven switching without level-shifting. Its 3-pin SOT23 footprint integrates gate, source, and drain with defined thermal path to solder point (R_th(j-sp) ≤ 65 K/W).

The PMV40UN features fast switching dynamics (t_d(on) = 6 ns, t_f = 12 ns), low gate charge (Q_g(tot) = 9.3 nC), and integrated body diode (V_SD = 0.66–1.2 V at I_S = 1.25 A), supporting synchronous rectification and reverse-current blocking in compact DC-DC and load-switch designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V maximum - supports 24 V rail and 12 V automotive battery systems with margin.
R_DS(on)	40–47 mΩ at V_GS = 4.5 V, T_j = 25 °C - enables <100 mW conduction loss at 2 A load.
I_D (continuous)	4.9 A at T_sp = 25 °C - suitable for medium-power load switches and motor drivers.
V_GS(th)	0.45–0.7 V typical - compatible with 1.8 V/2.5 V/3.3 V logic outputs without gate driver.
P_tot	1.9 W at T_sp = 25 °C - requires minimal PCB copper area for thermal relief in SOT23 layout.
Q_g(tot)	9.3 nC - reduces gate drive power and enables >1 MHz PWM operation with low-R_G.
C_iss	445 pF - balances switching speed and EMI control in high-frequency load switching.

Pinout & Package

PMV40UN is housed in a plastic surface-mounted SOT23 (TO-236AB) package with 3 leads, optimized for automated assembly and thermal performance via solder-point conduction.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control input terminal	Accepts logic-level voltage (≥0.7 V) to fully enhance channel; low C_iss minimizes drive energy.
2 (Source)	Reference node for gate drive and current return path	Connected to system ground or low-side return; body diode anode - blocks reverse current when floating.
3 (Drain)	Power output terminal	Carries load current up to 4.9 A; connected to positive rail or switched load; thermal path routed through PCB copper.

Key Features

Feature	Design Value
Ultra-low V_GS(th)	Enables direct interface with 1.8 V microcontrollers - eliminates level shifters in space-constrained IoT nodes.
TrenchMOS™ process	Delivers 20% lower R_DS(on) vs planar MOSFETs at same die size - improves power density in portable battery packs.
Low Q_g/Q_gd ratio	Q_gd/Q_g ≈ 24% - reduces Miller-induced switching delay and improves hard-switching efficiency.
Integrated body diode	V_SD = 0.66 V typical at 1.25 A - supports bidirectional current handling in USB power delivery and hot-swap circuits.
SOT23 thermal design	R_th(j-sp) ≤ 65 K/W - allows 1.9 W dissipation with <130 °C junction rise on 1-in² 2-oz copper pad.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2004LK-7	R_DS(on) = 32 mΩ @ V_GS = 4.5 V; higher Q_g = 12.5 nC; SOT23-3 package.	Better conduction loss but slower switching; suited for static load switching over PWM.	Select DMN2004LK-7 when minimizing I²R loss dominates over switching frequency requirements.
AO3400	R_DS(on) = 28 mΩ @ V_GS = 10 V; V_GS(th) = 0.7–1.4 V; higher threshold limits 1.8 V compatibility.	Requires ≥2.5 V gate drive for reliable turn-on; less suitable for ultra-low-voltage MCUs.	Choose AO3400 only if system uses ≥3.3 V GPIO and prioritizes lowest R_DS(on) over logic-level compatibility.

Compared with DMN2004LK-7 and AO3400, the PMV40UN uniquely balances sub-1 V threshold, 47 mΩ R_DS(on), and 9.3 nC gate charge - making it optimal for battery-powered systems where both low-voltage drive and moderate switching speed are required.

FAQ

What is the maximum continuous drain current for PMV40UN at 100 °C solder point temperature?

The PMV40UN supports a continuous drain current of 3.1 A at T_sp = 100 °C and V_GS = 4.5 V, as specified in Table 3 of the official datasheet. This derating reflects thermal limitations of the SOT23 package and must be accounted for in thermally constrained layouts. Designers should verify junction temperature using R_th(j-sp) = 65 K/W and actual power dissipation to ensure safe operation of the PMV40UN.

Does PMV40UN have a built-in body diode, and what is its forward voltage?

Yes, the PMV40UN includes an integrated source-drain body diode with a typical forward voltage (V_SD) of 0.66 V at I_S = 1.25 A and T_j = 25 °C. The datasheet confirms V_SD ranges from 0.66 V to 1.2 V depending on current and temperature. This diode enables freewheeling in inductive loads and reverse-current blocking in battery backup paths - a key feature leveraged in PMV40UN-based load-switch and hot-swap designs.

Can PMV40UN be driven directly by a 1.8 V microcontroller GPIO pin?

Yes, the PMV40UN can be driven directly by a 1.8 V GPIO because its gate-source threshold voltage (V_GS(th)) is specified at 0.45–0.7 V typical at T_j = 25 °C, well below 1.8 V. At V_GS = 1.8 V and I_D = 1 A, R_DS(on) is 55–73 mΩ - sufficient for many low-power switching tasks. However, designers should confirm actual R_DS(on) at operating temperature and load current using Figure 7 in the PMV40UN datasheet.

What is the thermal resistance from junction to solder point (R_th(j-sp)) for PMV40UN?

The PMV40UN has a maximum thermal resistance from junction to solder point (R_th(j-sp)) of 65 K/W, per Table 4 in the datasheet. This value applies under standard SOT23 mounting conditions and is used to calculate junction temperature rise above solder point temperature: ΔT_j = P_diss × R_th(j-sp). For example, at 1 W dissipation, the junction rises ~65 °C above the PCB solder point - a critical parameter for reliability validation of the PMV40UN in thermally dense layouts.

Is PMV40UN RoHS compliant and halogen-free?

Yes, the PMV40UN is RoHS compliant and halogen-free, consistent with Nexperia's standard environmental policy for all active components manufactured after 2006. The original Philips/NXP documentation predates full RoHS enforcement, but Nexperia's current product specifications and material declarations confirm compliance for PMV40UN in SOT23 packaging. Full substance declarations and test reports for the PMV40UN are available upon request from Aetrix Electronics' quality team.
