Product details
Overview
NX138AKS from Nexperia is a dual N-channel enhancement-mode Trench MOSFET in SOT363 (SC-88) package, rated for 60 V VDS, 170 mA continuous drain current per transistor, and 3 Ω typical RDS(on) at VGS = 10 V and Tj = 25 °C; used as low-side load switch or high-speed line driver in compact power management circuits.
For engineers reviewing the NX138AKS datasheet, NX138AKS pinout, NX138AKS application, or NX138AKS equivalent, key selection criteria include dual-channel integration in ultra-small SOT363, low 1.1 V typical gate threshold enabling 1.8–3.3 V logic drive, fast 10 ns rise time, and ESD-protected gate structure for robust PCB-level reliability.
Technical Context
This dual discrete MOSFET integrates two independent N-channel devices sharing no internal connection-each with isolated source, gate, and drain terminals. It employs Trench MOSFET technology to achieve low RDS(on) and fast switching while maintaining tight VGS(th) distribution (0.8–1.5 V).
The device operates in enhancement mode only, with no body diode connection between channels; each transistor supports unidirectional conduction with VSD = 0.8–1.2 V forward drop at IS = 170 mA and exhibits 1.4 nC max total gate charge for efficient gate driving at high frequencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V maximum - supports rail voltages up to 48 V DC in industrial control and telecom line interfaces |
| RDS(on) | 3 Ω typical at VGS = 10 V, ID = 170 mA - enables <100 mW conduction loss per channel at rated current |
| VGS(th) | 1.1 V typical - ensures reliable turn-on with 1.8 V or 3.3 V microcontroller GPIO without level shifting |
| QG(tot) | 1.4 nC maximum - allows clean 10–20 ns switching edges with ≤75 Ω gate resistor |
| ID (cont) | 170 mA per transistor at Tamb = 25 °C - suitable for driving small relays, LEDs, or logic-level signal routing |
| Ciss | 20 pF maximum - minimizes capacitive loading on driving ICs and improves noise immunity in dense layouts |
| Tj range | −55 to +150 °C - qualified for extended industrial temperature operation without derating below −40 °C |
Pinout & Package
Package: SOT363 (SC-88), 6-pin TSSOP, 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm pitch, FR4-compatible footprint with 1 cm² drain pad for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | S1 | Source terminal of transistor TR1 - connects to ground or low-side return path for first channel |
| 2 | G1 | Gate terminal of transistor TR1 - accepts logic-level input; ESD-protected, requires no external gate resistor for basic switching |
| 3 | D2 | Drain terminal of transistor TR2 - high-side node for second channel; electrically isolated from TR1 drain (pin 6) |
| 4 | S2 | Source terminal of transistor TR2 - independent return path; not internally tied to S1 (pin 1) |
| 5 | G2 | Gate terminal of transistor TR2 - fully independent control; supports asynchronous dual-channel switching |
| 6 | D1 | Drain terminal of transistor TR1 - primary high-side output node; thermally connected to exposed pad in standard layout |
Key Features
| Feature | Design Value |
|---|---|
| Low threshold voltage | VGS(th) = 1.1 V typ - enables direct interface with 1.8 V/3.3 V MCUs without gate drivers |
| Very fast switching | tr = 10 ns typ, tf = 5 ns typ - supports >10 MHz PWM in LED dimming or signal routing applications |
| Trench MOSFET architecture | RDS(on) × QG = ~4.2 Ω·nC - balances conduction and switching losses for space-constrained designs |
| ESD protection | HBM ≥2 kV - eliminates need for external TVS on gate lines in non-hostile environments |
| Thermal resistance | Rth(j-sp) = 100 K/W - achieves 1.33 W Ptot with minimal copper area, reducing board cost |
Applications
| Relay Driver | High-Speed Line Driver |
|---|---|
|
Use Scenario: Driving 5 V/12 V electromagnetic relays in PLC I/O modules or HVAC controllers. IC Role / Device Role / Timing Role: Low-side switch controlling relay coil current; dual configuration allows independent control of two relays in same footprint. Use Value: 170 mA rating covers common 5 V relay coils (e.g., 400 Ω, 12.5 mA); 3 Ω RDS(on) limits self-heating to <100 mW under full load. |
Use Scenario: Transmitting TTL/CMOS signals across noisy industrial backplanes or sensor cables. IC Role / Device Role / Timing Role: Active pull-down element in push-pull or open-drain line driver topology; fast edge rates preserve signal integrity. Use Value: 10 ns rise time maintains <100 MHz signal bandwidth; low Ciss avoids loading adjacent traces in dense routing. |
| Low-Side Load Switch | Switching Circuits |
|
Use Scenario: Power gating for auxiliary rails (e.g., USB VBUS, sensor bias, display backlight) in portable instrumentation. IC Role / Device Role / Timing Role: Single-channel load switch with integrated gate control; dual package allows redundant or parallel paths. Use Value: 1.1 V VGS(th) ensures full enhancement at 1.8 V supply; 60 V rating provides margin against inductive kickback. |
Use Scenario: Configurable logic-level translation or bidirectional signal isolation in FPGA/CPLD interface circuits. IC Role / Device Role / Timing Role: Discrete switch element in multiplexer, level shifter, or bus isolation stage; independent gates support synchronous/asynchronous control. Use Value: Pin-isolated dual structure prevents crosstalk; 150 °C Tj rating supports operation in sealed enclosures without forced cooling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2041LSD-13 | Higher VDS (20 V), lower RDS(on) (1.4 Ω), SOT-26 package | Better for ≤12 V systems requiring lower loss; unsuitable for 24–48 V rails due to voltage rating | Select when operating voltage ≤15 V and RDS(on) reduction is critical; verify SOT-26 footprint compatibility |
| NTJD4152PZ | Same SOT-363 package, but P-channel complement; VDS = −20 V, RDS(on) = 2.8 Ω | Used in high-side switching or complementary pair configurations-not drop-in replacement | Choose only for high-side or level-shifting topologies where P-channel behavior is required |
Compared with DMN2041LSD-13 and NTJD4152PZ, NX138AKS uniquely balances 60 V capability, 1.1 V logic compatibility, and dual-channel isolation in SOT363-making it optimal for mixed-voltage industrial signal routing where voltage headroom and GPIO drive simplicity are prioritized over ultra-low RDS(on).

FAQ
Is NX138AKS suitable for 5 V logic-level microcontroller drive?
Yes. With a typical gate threshold voltage of 1.1 V and maximum of 1.5 V, NX138AKS fully enhances using standard 3.3 V or 5 V GPIO outputs. No external level shifter or gate driver is needed for reliable switching at up to 170 mA per channel.
Does NX138AKS integrate back-to-back MOSFETs or share any internal connections between channels?
No. NX138AKS contains two fully independent N-channel MOSFETs-no shared source, drain, or substrate connection. Pins 1/S1 and 4/S2 are separate; pins 3/D2 and 6/D1 are isolated. This enables true dual-channel operation in asymmetric topologies.
What is the maximum continuous power dissipation per channel at 70 °C ambient?
At Tamb = 70 °C, derated Ptot is approximately 0.75 W per device (1.5 W total), based on Fig. 1's normalized curve and Rth(j-a) = 500 K/W. Each channel contributes half, so ~375 mW/channel is sustainable with standard FR4 layout and no forced airflow.
Can NX138AKS replace a single discrete MOSFET in existing SOT-23 designs?
No. NX138AKS uses SOT363 (6-pin), not SOT-23 (3-pin). Its pinout and dual-channel function require PCB redesign. For SOT-23 drop-in alternatives, consider single-channel equivalents like PMV16XNR or NX138A (if available), not the dual NX138AKS.
