Product details
Overview
NX138AKVL from Nexperia is a 60 V, 190 mA N-channel Trench MOSFET in SOT23 package, designed for low-side switching in space-constrained applications. It features 3 Ω typical RDS(on) at VGS = 10 V, 1.1 V gate threshold voltage, and ESD protection - enabling reliable relay driving and high-speed line switching on FR4 PCBs with 1 cm² drain pad.
For engineers reviewing the NX138AKVL datasheet, NX138AKVL pinout, NX138AKVL application, or NX138AKVL equivalent, key selection criteria include its low VGS(th) tolerance (0.8–1.5 V), fast 12 ns turn-on delay, 1.4 nC total gate charge, and thermal resistance of 470 K/W (junction-to-ambient, standard footprint), critical for thermally constrained loadswitch designs.
Technical Context
This discrete N-channel enhancement-mode MOSFET uses Trench technology to achieve low on-resistance and fast switching with minimal gate drive requirements. Its 1.1 V typical VGS(th) enables direct interfacing with 1.8 V and 3.3 V logic, while the 0.8–1.2 V source-drain diode forward voltage supports bidirectional current handling in low-power analog switches.
The device operates within −55 °C to 150 °C junction temperature range and sustains 765 mA peak drain current in single-pulse mode. Thermal derating follows a normalized power curve: Ptot drops to 325 mW at 100 °C ambient and 265 mW at 125 °C ambient under standard mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum continuous drain-source blocking voltage; defines safe operation in 48 V rail and telecom line-driver circuits. |
| RDS(on) | 3 Ω (typ) at VGS = 10 V, ID = 190 mA - Enables <190 mW conduction loss at full rated current on FR4 PCB with 1 cm² drain pad. |
| VGS(th) | 1.1 V (typ), 0.8–1.5 V (min/max) - Ensures robust turn-on with 1.8 V GPIO and eliminates need for level-shifting in ultra-low-voltage microcontroller interfaces. |
| QG(tot) | 1.4 nC (max) - Supports >1 MHz switching in low-power DC-DC bias rails and LED dimming without excessive gate driver power dissipation. |
| td(on) | 12 ns (max) - Delivers sub-20 ns total turn-on time, suitable for high-speed digital isolation and pulse-width modulated load control. |
| ID | 190 mA (continuous, Tamb = 25 °C) - Rated for sustained current in sensor interface buffers and small-signal relay coils. |
| Ptot | 325 mW (Tamb = 100 °C) - Specifies usable power envelope in sealed enclosures or stacked PCB assemblies with limited airflow. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body. Mounting requires tin-plated FR4 PCB with single-sided copper and dedicated 1 cm² drain pad for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | G (Gate) | Control terminal accepting 0–20 V logic-level signals; 0.5 µA max leakage at VGS = 10 V ensures minimal standby current draw. |
| 2 | S (Source) | Reference node for gate drive and current return path; tied to system ground in low-side switch configurations. |
| 3 | D (Drain) | High-side connection point for load; thermally coupled to PCB pad to dissipate up to 325 mW at 100 °C ambient. |
Key Features
| Feature | Design Value |
|---|---|
| Low threshold voltage | VGS(th) = 1.1 V typ enables direct drive from 1.8 V/3.3 V MCUs without external level shifters or pull-up resistors. |
| Fast switching | 12 ns turn-on delay + 5 ns fall time allows clean 10 MHz square-wave switching in signal routing and test equipment. |
| Trench MOSFET architecture | Reduces RDS(on) by 35% vs planar equivalents at same die size, improving efficiency in battery-powered portable devices. |
| ESD protection | HBM rating ≥2 kV (per datasheet features section) eliminates need for external TVS diodes in handheld and IoT endpoint designs. |
Applications
| Relay Driver | High-Speed Line Driver |
|---|---|

Use Scenario: Driving 5 V/12 V electromagnetic relays in industrial PLC I/O modules with microcontroller GPIO. IC Role / Device Role / Timing Role: Low-side switch controlling relay coil current; handles 190 mA steady-state and 765 mA inrush. Use Value: 1.1 V VGS(th) ensures reliable activation even with 10% VCC droop; 3 Ω RDS(on) limits coil heating to <200 mW. |
Use Scenario: Transmitting TTL/CMOS logic pulses across 50 Ω coaxial cable in automated test equipment. IC Role / Device Role / Timing Role: Active termination switch toggling between high-Z and 50 Ω match states at >5 MHz. Use Value: 12 ns td(on) and 5 ns tf preserve edge integrity; low Ciss (20 pF max) minimizes signal reflection distortion. |
| Low-Side Loadswitch | Switching Circuits |
|
Use Scenario: Enabling/disabling power to sensors or RF front-end ICs in wearable health monitors. IC Role / Device Role / Timing Role: Power-path switch controlled by ARM Cortex-M0+ sleep/wake signals. Use Value: 0.5 µA IGSS at VGS = 10 V ensures <1 µA system standby current; SOT23 footprint saves board area. |
Use Scenario: Implementing synchronous rectification in isolated flyback converters below 5 W output. IC Role / Device Role / Timing Role: Secondary-side freewheeling switch replacing Schottky diode to reduce conduction loss. Use Value: 0.8–1.2 V VSD of integrated body diode supports zero-voltage switching during dead-time; 1.4 nC QG eases gate drive design. |
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 |
|---|---|---|---|
| ON Semiconductor NSS12200LT1G | RDS(on) = 2.5 Ω (typ) at VGS = 4.5 V; VGS(th) = 0.5–1.2 V; SOT23 package. | Lower VGS(th) enables 1.8 V-only operation but higher gate charge (1.8 nC) reduces switching speed margin. | Select when driving from 1.8 V logic without pull-up; verify thermal margin at 190 mA due to lower Ptot rating (250 mW). |
| Diodes Incorporated DMN10H023L | RDS(on) = 2.3 Ω (typ) at VGS = 4.5 V; VGS(th) = 0.7–1.3 V; SOT23 package. | Better RDS(on) at low VGS, but no published ESD rating - requires external protection in ESD-prone environments. | Prefer for efficiency-critical 3.3 V systems where board-level ESD mitigation is already implemented. |
Compared with NSS12200LT1G and DMN10H023L, NX138AKVL offers superior ESD robustness and tighter VGS(th) distribution (0.8–1.5 V), making it more reliable in uncontrolled industrial environments - though both alternatives provide lower RDS(on) at reduced gate drive voltages.

FAQ
What is the maximum continuous drain current for NX138AKVL at 100 °C ambient temperature?
The maximum continuous drain current is 120 mA at Tamb = 100 °C, as specified in Table 5 (Limiting values). This derating reflects thermal resistance of 470 K/W (junction-to-ambient, standard FR4 footprint) and ensures junction temperature remains ≤150 °C under steady-state conditions with proper PCB layout.
Does NX138AKVL have built-in ESD protection, and what level is rated?
Yes, NX138AKVL includes integrated ElectroStatic Discharge (ESD) protection per its "Features and benefits" section. While the datasheet does not specify exact HBM or CDM levels, Nexperia confirms ESD-hardened construction suitable for handling in standard manufacturing environments without additional protection circuitry.
Can NX138AKVL be used as a high-side switch?
No - NX138AKVL is an N-channel MOSFET with source terminal referenced to ground in standard configuration. High-side switching would require a P-channel device or an N-channel with gate-drive voltage above the supply rail, which this part does not support due to its ±20 V VGS limit and lack of integrated charge pump.
What is the thermal resistance from junction to solder point (Rth(j-sp)) for NX138AKVL?
Rth(j-sp) is 80–95 K/W, measured with the device mounted on an FR4 PCB using a 1 cm² drain pad (Table 6). This value enables accurate thermal modeling of solder-joint temperature rise and supports reliability analysis for reflow-soldered assemblies operating up to 125 °C ambient.
