Product details
Overview
NX3008NBK from Nexperia is a 30 V, 400 mA N-channel enhancement-mode Trench MOSFET in SOT23 package, designed for low-side switching in space-constrained automotive and industrial circuits. It features 1.0 Ω typical RDS(on) at VGS = 4.5 V, 0.9 V typical gate threshold voltage, and AEC-Q101 qualification for under-hood relay drivers and high-speed line interfaces.
For engineers reviewing the NX3008NBK datasheet, NX3008NBK pinout, NX3008NBK application, or NX3008NBK equivalent, key selection criteria include its 2 kV HBM ESD rating, 310 K/W junction-to-ambient thermal resistance on FR4, fast 11 ns rise time, and compatibility with 1.8 V–4.5 V logic-level gate drive in load-switching designs.
Technical Context
This discrete MOSFET uses Trench technology to achieve low on-resistance and fast switching with minimal gate charge (0.52 nC typical total QG). Its 0.9 V VGS(th) enables reliable turn-on from 1.8 V microcontroller I/O, while the integrated source-drain diode supports bidirectional current paths in PWM-driven loads.
The device operates across –55 °C to 150 °C junction temperature, with normalized RDS(on) rising to 1.8× at 150 °C. Thermal derating follows a defined curve: continuous drain current drops to 250 mA at 100 °C ambient, and power dissipation falls to 350 mW at 25 °C ambient on standard FR4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum blocking voltage for 24 V automotive rail and industrial 28 V systems |
| RDS(on) | 1.0 Ω @ VGS = 4.5 V, ID = 350 mA, Tj = 25 °C - Enables <100 mW conduction loss at 350 mA |
| VGS(th) | 0.9 V typ - Ensures full enhancement with 1.8 V GPIO without level-shifting |
| QG(tot) | 0.52 nC - Supports >1 MHz switching with low gate-drive power in compact DC-DC or LED drivers |
| tr/tf | 11 ns / 19 ns - Minimizes switching transition losses in high-frequency load control |
| ESD Rating | 2000 V HBM - Eliminates need for external ESD protection in board-level assembly |
| Ptot | 350 mW @ Tamb = 25 °C - Sustains 400 mA continuous current only with adequate PCB copper area (1 cm² drain pad) |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, 3-terminal configuration with tin-plated leads and standard FR4-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | G (Gate) | Control input requiring ≤0.52 nC charge for full enhancement; sensitive to ESD but protected to 2 kV HBM |
| 2 | S (Source) | Reference node for gate drive; connects to system ground or low-side return path in load-switch configurations |
| 3 | D (Drain) | High-current output terminal; requires 1 cm² copper pad on FR4 for rated 400 mA continuous operation |
Key Features
| Feature | Design Value |
|---|---|
| Trench MOSFET architecture | Delivers 1.0 Ω RDS(on) in SOT23 - 40% lower than planar equivalents at same current rating |
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock testing |
| Low VGS(th) (0.6–1.1 V) | Guarantees turn-on with 1.8 V logic; eliminates external level shifters in ultra-low-voltage MCU designs |
| Fast switching (tr = 11 ns) | Reduces transition losses by >30% vs. comparable SOT23 MOSFETs in 500 kHz PWM applications |
| Integrated source-drain diode | VSD = 0.85 V @ 350 mA enables freewheeling in inductive load circuits without external diode |
Applications
| Automotive Relay Driver | Industrial Low-Side Load Switch |
|---|---|
|
Use Scenario: Driving 12 V/24 V automotive relays in body control modules where space and thermal budget are constrained. IC Role / Device Role / Timing Role: N-channel low-side switch controlling relay coil current up to 400 mA with logic-level gate drive from MCU GPIO. Use Value: Eliminates need for bipolar driver transistors or dedicated gate drivers; 0.9 V VGS(th) ensures robust turn-on even with battery droop to 9 V. |
Use Scenario: Power gating of sensors, LEDs, or actuators in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Discrete load switch enabling ON/OFF control with <1 µA off-state leakage and <100 mΩ effective on-resistance at 350 mA. Use Value: Reduces BOM count by replacing dual-transistor or IC-based switches; 2 kV ESD rating prevents field failures during handling and assembly. |
| High-Speed Line Driver | USB/Serial Interface Protection |
|
Use Scenario: Driving short-haul RS-485 or CAN bus stub lines in industrial gateways where signal integrity demands fast edge rates. IC Role / Device Role / Timing Role: Active termination switch toggling between active and high-Z states with 11 ns rise time and sub-10 ns propagation delay. Use Value: Maintains signal fidelity up to 10 Mbps by minimizing transition distortion; low Ciss (34 pF) avoids capacitive loading on data lines. |
Use Scenario: Overvoltage and reverse-polarity protection for USB VBUS or UART TX/RX lines in portable test equipment. IC Role / Device Role / Timing Role: Reverse-blocking switch placed in series with supply or signal path, leveraging intrinsic body diode directionality and low RDS(on). Use Value: Provides <100 mΩ forward path resistance and <1 µA reverse leakage - superior to Schottky diodes in low-drop, low-leakage protection schemes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel low-side switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LSD-13 | RDS(on) = 0.75 Ω @ 4.5 V but larger TSOP-6 package (3.05 × 1.65 mm); no AEC-Q101 rating | Better conduction loss but unsuitable for automotive qualification-critical designs | Select when higher current (6 A) capability and lower RDS(on) outweigh package size and qualification needs |
| AO3400 | VGS(th) = 1.0–2.0 V (wider spread); RDS(on) = 0.85 Ω @ 4.5 V; non-automotive grade | Higher gate threshold increases risk of partial turn-on with 1.8 V logic; no ESD or AEC validation | Choose only for cost-sensitive consumer applications where qualification and ESD immunity are not required |
Compared with DMN3025LSD-13 and AO3400, NX3008NBK offers the smallest footprint (SOT23), guaranteed low-threshold operation for 1.8 V MCUs, and automotive-grade reliability - making it optimal for space-limited, safety-aware embedded switching where consistent turn-on and field robustness are mandatory.

FAQ
What is the maximum continuous drain current for NX3008NBK at 100 °C ambient temperature?
The maximum continuous drain current is 250 mA at Tamb = 100 °C, as specified in Table 5 (Limiting values). This derating accounts for thermal resistance limitations on standard FR4 PCBs without enhanced copper heatsinking. Operation above this current requires thermal simulation or increased copper area to maintain Tj ≤ 150 °C.
Does NX3008NBK require an external gate resistor for 5 V MCU drive?
No external gate resistor is required for basic switching, but a 10–47 Ω series resistor is recommended to dampen ringing and reduce EMI in layouts with >10 cm trace length. The device's low QG (0.52 nC) allows full turn-on with <100 ns delay using typical 5 V GPIO drivers without slew-rate limiting.
Can NX3008NBK be used in reverse polarity protection circuits?
Yes - its intrinsic body diode blocks reverse current when the drain is grounded and source is connected to the supply. With VSD = 0.85 V at 350 mA, it provides lower forward drop than most Schottky diodes in compact footprints, though it must be oriented correctly to exploit unidirectional conduction.
Is the SOT23 package lead-free and RoHS compliant?
Yes - NX3008NBK is manufactured in a lead-free, RoHS-compliant SOT23 package per Nexperia's product compliance documentation. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and supports standard reflow profiles including IPC/JEDEC J-STD-020 Rev. E.
