Product details

Overview

PMH400UNE from Nexperia is a 30 V, N-channel enhancement-mode Trench MOSFET in a leadless DFN0606-3 (SOT8001) package, optimized for low-side load switching and high-speed line driving. It delivers R_DS(on) = 400 mΩ at V_GS = 4.5 V, 0.7 A, with 1.7 kV HBM ESD protection and ultra-small footprint (0.62 × 0.62 × 0.37 mm).

For engineers reviewing the PMH400UNE datasheet, PMH400UNE pinout, PMH400UNE application, or PMH400UNE equivalent, this device supports compact power management in space-constrained portable electronics, battery-powered logic interfaces, and fast-switching signal routing where thermal efficiency and gate drive simplicity are critical.

Technical Context

This MOSFET uses Trench technology to achieve low threshold voltage (V_GS(th) = 0.45–0.95 V) and fast switching (t_d(on) = 1 ns, t_f = 2 ns), enabling efficient operation with 1.8 V–4.5 V logic-level gate drive. Its ultra-thin DFN0606-3 package minimizes parasitic inductance and improves thermal coupling to PCB copper.

Designed for single-ended low-side switching, it features a body diode with V_SD = 0.7–1.2 V at I_S = 0.6 A and exhibits stable R_DS(on) over temperature (R_DS(on) = 715–825 mΩ at T_j = 150 °C, V_GS = 4.5 V), supporting reliable performance in ambient temperatures up to 150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V maximum drain-source voltage - supports rail-to-rail switching in 3.3 V and 5 V systems with margin against transients.
R_DS(on)	400 mΩ typical at V_GS = 4.5 V, I_D = 0.7 A - enables <100 mW conduction loss at 0.5 A, reducing thermal load on small PCBs.
V_GS(th)	0.7 V typical - ensures full enhancement with 1.8 V GPIO, eliminating need for level-shifting in modern microcontrollers.
Q_G(tot)	0.62–0.93 nC - allows sub-10 ns switching with low gate-drive current (<1 mA average), minimizing driver stress.
T_j max	150 °C - permits operation in sealed enclosures or near heat sources without derating below 100 °C ambient.
R_th(j-a)	287–344 K/W - defines thermal limit of ~0.36 W continuous dissipation on standard FR4, guiding layout decisions for copper area.

Pinout & Package

DFN0606-3 (SOT8001) is a leadless, ultra-small surface-mount plastic package measuring 0.62 × 0.62 × 0.37 mm, with exposed drain pad for thermal conduction and no leads to minimize parasitic inductance.

Pin/Terminal	Circuit Role	Design Meaning
1	G (Gate)	Control terminal; requires ≤8 V drive; low input capacitance (C_iss = 45.4 pF) reduces gate drive energy.
2	S (Source)	Reference node for gate drive and current return path; tied to system ground in low-side configuration.
3	D (Drain)	High-current output node; connected to exposed copper pad for thermal dissipation and low-inductance routing.

Key Features

Feature	Design Value
Ultra-low R_DS(on) at 1.8 V V_GS	580–670 mΩ enables direct MCU GPIO control without external drivers in battery-powered sensors.
ESD robustness	1.7 kV HBM rating eliminates need for external TVS in handheld device I/O stages.
Sub-1 ns turn-on delay	t_d(on) = 1 ns supports >100 MHz digital switching in test equipment and data acquisition front-ends.
Thermally optimized package	R_th(j-sp) = 47–56 K/W to solder point enables >2× power handling vs. comparable SOT-23 devices on same PCB area.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN10H400L	R_DS(on) = 380 mΩ @ 4.5 V but larger DFN1006-3 (1.0 × 0.6 mm); no HBM rating specified.	Higher thermal mass supports higher continuous current but occupies 60% more board area.	Choose when PCB layout allows larger footprint and ESD protection is handled externally.
AO3400A	R_DS(on) = 44 mΩ @ 10 V but V_GS(th) = 0.8–1.5 V; SOT-23 package with higher R_th(j-a) (350 K/W).	Lower on-resistance at 10 V drive, but requires ≥2.5 V gate for reliable turn-on and dissipates more heat per watt.	Choose only if gate drive ≥3.3 V is guaranteed and thermal relief via heatsink or large copper is feasible.

Compared with DMN10H400L and AO3400A, PMH400UNE uniquely balances ultra-compact size, 1.7 kV ESD immunity, and 1.8 V logic compatibility-making it optimal for wearables, hearing aids, and IoT edge nodes where board space and robustness are non-negotiable.

FAQ

What is the maximum continuous drain current for PMH400UNE at 100 °C ambient?

The maximum continuous drain current is 0.57 A at T_amb = 100 °C with device mounted on FR4 PCB (single-sided copper, 1 cm² drain pad). This value reflects thermal derating due to reduced heat dissipation at elevated ambient, not electrical limitation - the device remains fully functional within its 30 V V_DS and 8 V V_GS ratings.

Does PMH400UNE require external gate resistors for stability?

No external gate resistor is required for basic switching stability due to its low gate charge (0.62–0.93 nC) and intrinsic gate resistance (11.6 Ω). However, a 10–47 Ω series resistor is recommended when driving from high-impedance sources or in noisy environments to damp ringing and reduce EMI during fast transitions.

Can PMH400UNE be used in reverse conduction mode (source-to-drain)?

Yes - its integrated body diode supports source-to-drain conduction with V_SD = 0.7–1.2 V at I_S = 0.6 A and T_j = 25 °C. However, reverse recovery is not characterized, so it is unsuitable for synchronous rectification or high-frequency freewheeling; use only for slow, low-duty-cycle flyback paths.

Is the DFN0606-3 package compatible with standard reflow profiles?

Yes - the DFN0606-3 (SOT8001) package is qualified for JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C. Recommended footprint uses 0.30 mm wide solder lands and 0.21 mm solder mask openings, as specified in Nexperia's sot8001_fr document (Issue date: 2018-11-30).
