Product details
Overview
PMZB290UN from Nexperia is a single N-channel enhancement-mode Trench MOSFET in a DFN1006B-3 (SOT883B) ultra-thin surface-mount package, rated for 20 V drain-source voltage, 1 A continuous drain current at 25 °C, and 290 mΩ typical RDS(on) at VGS = 4.5 V - optimized for low-side load switching in space-constrained portable electronics.
For engineers reviewing the PMZB290UN datasheet, PMZB290UN pinout, PMZB290UN application, or PMZB290UN equivalent, key selection criteria include its 0.37 mm profile height, 2 kV HBM ESD rating, fast 4.5 ns turn-on delay, and guaranteed operation down to –55 °C ambient temperature.
Technical Context
This MOSFET employs Trench technology to achieve low gate charge (0.89 nC typical) and high transconductance (5.8 S), enabling efficient switching in battery-powered systems where gate drive strength is limited. Its sub-threshold behavior is characterized by a 0.45–0.95 V gate threshold voltage range at 25 °C.
The device features an integrated source-drain diode with 0.75–1.2 V forward voltage at 300 mA, and thermal resistance of 305 K/W junction-to-ambient on FR4 PCB - critical for thermal management in unheatsinked layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 20 V maximum - defines safe operating voltage ceiling for low-voltage logic-level switching applications. |
| RDS(on) | 290 mΩ typical at VGS = 4.5 V, ID = 200 mA, Tj = 25 °C - enables <100 mW conduction loss at 0.5 A load current. |
| VGS(th) | 0.7 V typical - ensures reliable turn-on with 1.8 V or higher logic outputs, supporting modern low-voltage microcontrollers. |
| QG(tot) | 0.89 nC typical - reduces gate drive power and allows use with weak GPIOs or low-current drivers. |
| Tj max | 150 °C - sets maximum junction temperature limit for continuous operation under thermal derating curves. |
| ESD Rating | 2 kV HBM - provides robustness against handling-induced electrostatic discharge without external protection. |
| Ptot | 360 mW at Tamb = 25 °C on FR4 - defines maximum steady-state power dissipation before thermal shutdown or reliability risk. |
Pinout & Package
Package: DFN1006B-3 (SOT883B), leadless ultra-small plastic package; dimensions 1.0 × 0.6 × 0.37 mm; 3 solder lands; tin-plated copper pad for drain thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | G (Gate) | Control terminal; accepts logic-level voltage (≤8 V) to modulate channel conductivity; high-impedance input requiring minimal drive current. |
| 2 | S (Source) | Reference node for gate voltage and return path for load current; internally connected to substrate; must be tied to system ground in low-side configuration. |
| 3 | D (Drain) | Power output terminal; connects to load; thermally coupled to PCB mounting pad for heat dissipation; carries full switched current. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-thin profile | 0.37 mm height - enables integration into slim handheld devices and wearables where Z-height is constrained. |
| Low RDS(on) at 1.8 V VGS | 650 mΩ max - supports partial turn-on for analog control or PWM dimming in low-voltage LED drivers. |
| Fast switching speed | 9 ns max turn-off delay - minimizes transition losses in high-frequency (>1 MHz) DC-DC or motor control circuits. |
| ESD-protected gate | 2 kV HBM rating - eliminates need for external gate protection diodes in production assembly lines. |
| Thermal performance | Rth(j-sp) = 40 K/W - enables direct thermal coupling to PCB copper, improving reliability over standard SOT packages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel low-voltage MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN10H023R | RDS(on) = 23 mΩ at VGS = 4.5 V - 12× lower than PMZB290UN; larger SOT-23 package (2.9 × 1.3 × 1.0 mm). | Requires more PCB area and higher gate drive current; suited for higher-current (>2 A), less space-constrained designs. | Select when lower conduction loss outweighs size and cost constraints; verify thermal margin with larger footprint. |
| AO3400 | RDS(on) = 28 mΩ at VGS = 10 V but only 45 mΩ at VGS = 2.5 V - weaker low-voltage drive capability than PMZB290UN's 650 mΩ at 1.8 V. | Less suitable for 1.8 V/2.5 V logic interfaces; better for 3.3 V/5 V systems with higher gate drive availability. | Prefer for legacy 3.3 V systems where gate drive strength is ample and ultra-thin profile is not required. |
Compared with DMN10H023R and AO3400, the PMZB290UN uniquely balances ultra-miniature packaging, strong 1.8 V turn-on, and 2 kV ESD tolerance - making it optimal for next-gen compact battery-powered systems where board space and low-voltage compatibility are non-negotiable.

FAQ
What is the maximum continuous drain current for PMZB290UN at 100 °C ambient temperature?
The maximum continuous drain current is 0.6 A at Tamb = 100 °C, as specified in Table 5 (Limiting values). This derating reflects thermal limitations on FR4 PCB with single-sided copper; actual current capacity depends on PCB copper area and airflow.
Does PMZB290UN require external gate resistors for ESD protection?
No - the device integrates 2 kV HBM ESD protection on the gate terminal, eliminating the need for external series resistors or TVS diodes in standard handling and operation. External gate resistors may still be used for switching speed control or ringing suppression.
Can PMZB290UN be used in a high-side switching configuration?
No - the PMZB290UN is a single N-channel MOSFET with source tied to internal substrate; it lacks a floating gate driver and body diode orientation required for high-side operation. It is designed exclusively for low-side switching where source connects to ground.
What is the recommended reflow soldering footprint for DFN1006B-3 package?
The official footprint specifies 0.35 mm wide × 0.65 mm long solder lands for pins 1 (G) and 2 (S), and a 0.95 mm × 0.65 mm thermal pad for pin 3 (D), with 0.25 mm solder paste stencil openings - per Figure 20 in the datasheet.
