Product details

Overview

NX3008PBKMB,315 from Nexperia is a P-channel enhancement-mode Trench MOSFET in a DFN1006B-3 (SOT883B) package, designed for high-side load switching and relay driving. It features a -30 V drain-source voltage rating, 2.8 Ω typical R_DS(on) at V_GS = -4.5 V and I_D = -200 mA, -0.9 V typical gate threshold voltage, 0.37 mm profile height, and 2 kV HBM ESD protection.

For engineers reviewing the NX3008PBKMB,315 datasheet, NX3008PBKMB,315 pinout, NX3008PBKMB,315 application, or NX3008PBKMB,315 equivalent, this device serves as a compact, low-threshold, fast-switching P-channel switch for space-constrained DC power control circuits requiring minimal gate drive and robust transient immunity.

Technical Context

This MOSFET employs Trench MOSFET technology to achieve low on-resistance and fast switching with minimal gate charge (0.55 nC typical total gate charge). Its ultra-thin 0.37 mm DFN1006B-3 package enables integration into high-density portable and wearable electronics where thermal and spatial constraints are critical.

The device operates with a low gate threshold of -0.9 V (typ), enabling direct interface with 1.8 V and 2.5 V logic outputs, and supports continuous drain currents up to -300 mA at 25 °C ambient. Its source-drain diode exhibits a forward voltage of -0.88 V at -200 mA, supporting bidirectional current handling in load-switch configurations.

Key Specifications

V_DS	-30 V maximum - supports 24 V rail switching with 20 % safety margin
R_DS(on)	2.8 Ω typ @ V_GS = -4.5 V, I_D = -200 mA - limits conduction loss to ≤112 mW at rated current
V_GS(th)	-0.9 V typ - ensures reliable turn-on with 1.8 V/2.5 V GPIO without level shifting
Q_G(tot)	0.55 nC typ - enables <40 ns turn-on delay and <130 ns turn-off delay with 6 Ω gate resistor
ESD Rating	2 kV HBM - provides robust handling during PCB assembly and field operation
Package Height	0.37 mm - fits under 0.4 mm Z-height connectors and stacked flex assemblies
P_tot	360 mW @ T_amb = 25 °C - defines thermal derating curve for FR4 PCBs with standard footprint

Pinout & Package

DFN1006B-3 (SOT883B) is a 3-terminal, leadless, ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.37 mm, with exposed drain pad for thermal conduction and solderable side terminals.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel MOSFET switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2020LFG-7	20 V V_DS, 1.8 Ω R_DS(on), same DFN1006B-3 package	Limited to ≤20 V systems; better R_DS(on) but lower voltage margin	Select when 20 V rail and lowest possible conduction loss are prioritized over voltage headroom
PMZB390UNEY	30 V V_DS, 4.5 Ω R_DS(on), same package, -1.2 V V_GS(th)	Higher threshold requires ≥3.3 V logic; higher R_DS(on) increases conduction loss by ~60 %	Select when cost sensitivity outweighs performance, and 3.3 V+ gate drive is available

Compared with DMN2020LFG-7 and PMZB390UNEY, NX3008PBKMB,315 uniquely balances -30 V capability, -0.9 V threshold, and 2.8 Ω R_DS(on) in the DFN1006B-3 footprint-making it optimal for 1.8–2.5 V logic-driven, 24 V-compatible high-side switches where space and thermal density are constrained.

FAQ

What is the maximum continuous drain current for NX3008PBKMB,315 at 100 °C ambient?

The maximum continuous drain current is -185 mA at T_amb = 100 °C with V_GS = -4.5 V, as specified in the Limiting Values table. This reflects thermal derating due to reduced power dissipation capability at elevated ambient temperatures on standard FR4 PCBs.

Can NX3008PBKMB,315 be used in high-side switch configurations with 3.3 V microcontroller GPIO?

Yes - its -0.9 V typical V_GS(th) and -1.1 V maximum ensure full enhancement with 3.3 V logic (V_GS = -3.3 V), delivering ≤4.1 Ω R_DS(on). No level shifter is required, simplifying circuit design and reducing BOM count.

Is the DFN1006B-3 package thermally enhanced for PCB mounting?

Yes - the DFN1006B-3 package features an exposed drain pad that must be soldered to a ≥1 cm² copper area on the PCB to achieve the specified R_th(j-a) of 150 K/W. Without this thermal pad, junction-to-ambient resistance degrades to 305 K/W, limiting usable power.

Does NX3008PBKMB,315 include body diode functionality, and what is its forward voltage?

Yes - it integrates a source-drain body diode with V_SD = -0.88 V typical at I_S = -200 mA and T_j = 25 °C. This enables freewheeling in inductive loads and reverse-current blocking in high-side configurations without external diodes.
