Product details
Overview
PMX400UPEZ from Nexperia is a P-channel enhancement-mode Trench MOSFET in a DFN0603-3 (SOT8013) package, designed for high-side load switching and battery protection circuits. It delivers −20 V drain-source voltage rating, 425 mΩ typical RDS(on) at VGS = −4.5 V, and −900 mA continuous drain current at 25 °C ambient - enabling compact, low-loss power control in space-constrained portable electronics.
For engineers reviewing the PMX400UPEZ datasheet, PMX400UPEZ pinout, PMX400UPEZ application, or PMX400UPEZ equivalent, key selection criteria include its ultra-small 0.63 × 0.33 mm footprint, low 0.25 mm profile, ESD robustness (>2 kV HBM), and verified performance in battery-switch and high-speed line-driver roles per Nexperia's 2023 product data sheet.
Technical Context
This device operates as a single P-channel switch with gate-controlled conduction between drain and source. Its trench MOSFET architecture enables low threshold voltage (−0.7 V typ.) and stable RDS(on) across temperature - critical for reliable turn-on in low-voltage battery systems (e.g., 3.3 V or 5 V rails).
The DFN0603-3 package features an exposed drain pad optimized for thermal dissipation on FR4 PCBs with 1 cm² copper area, achieving 23–26.5 K/W junction-to-solder-point thermal resistance. Gate charge parameters (QG(tot) = 1.6–2.3 nC, QGD = 0.5 nC) support fast switching in high-frequency load-switching applications up to several MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | −20 V - Maximum allowable drain-to-source voltage; defines safe operating range in battery-input circuits. |
| RDS(on) | 425 mΩ (typ.) at VGS = −4.5 V, ID = −1 A, Tj = 25 °C - Directly determines conduction loss and heat generation in load-switch designs. |
| VGS(th) | −0.7 V (typ.) - Enables full enhancement with logic-level gate drive from 1.8 V or 3.3 V microcontrollers. |
| ID (cont.) | −900 mA at Tamb = 25 °C - Specifies maximum steady-state current under standard PCB mounting conditions. |
| QG(tot) | 1.6–2.3 nC - Governs gate driver strength requirement and switching speed in PWM or enable-controlled circuits. |
| ESD Rating | >2 kV HBM - Ensures robustness against handling-induced electrostatic discharge during assembly and field operation. |
| Tj max | 150 °C - Sets upper thermal limit for reliability in sealed or thermally restricted enclosures. |
Pinout & Package
Package: DFN0603-3 (SOT8013), ultra-small leadless plastic package measuring 0.63 mm × 0.33 mm × 0.25 mm with 0.225 mm pitch and exposed drain pad for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | G (Gate) | Control terminal; accepts negative VGS to turn on P-channel conduction; requires no level-shifting for 3.3 V logic drive. |
| 2 | S (Source) | Reference node for gate drive; connected to higher potential rail (e.g., battery +) in high-side switch configuration. |
| 3 | D (Drain) | Current output terminal; electrically tied to exposed bottom pad for enhanced thermal conduction to PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-compact footprint | 0.63 mm × 0.33 mm - Reduces PCB area by >50% vs. SOT-23, enabling dense battery-management layouts. |
| Low-profile height | 0.25 mm - Supports thin-profile wearable and IoT devices where Z-axis clearance is constrained. |
| Trench MOSFET process | 425 mΩ RDS(on) at −4.5 V - Delivers lower conduction loss than planar P-MOSFETs of comparable size. |
| Integrated ESD protection | >2 kV HBM - Eliminates need for external TVS diodes in handheld device battery-switch paths. |
| Thermally optimized drain pad | Rth(j-sp) = 23–26.5 K/W - Enables 4.7 W peak power dissipation with proper PCB copper layout. |
Applications

FAQ
What is the maximum continuous drain current for PMX400UPEZ at 100 °C ambient?
The PMX400UPEZ supports −500 mA continuous drain current at Tamb = 100 °C when mounted on an FR4 PCB with single-sided copper and tin-plated pads, per Table 5 of the 2023 datasheet. This derating reflects thermal limitations of the DFN0603-3 package under elevated ambient conditions.
Does PMX400UPEZ require a gate resistor for stable switching?
A gate resistor is recommended to dampen ringing and control slew rate, especially in high-frequency enable applications. With QG(tot) = 1.6–2.3 nC and fast tr/tf (17 ns/35 ns), a 10–47 Ω series resistor balances switching speed and EMI mitigation without compromising turn-on delay.
Can PMX400UPEZ be used in automotive applications?
No - the PMX400UPEZ is not automotive-qualified. Nexperia explicitly states in Section 15 of the datasheet that non-automotive qualified products are unsuitable for automotive use and lack AEC-Q101 testing, temperature grading, or failure-rate validation required for vehicle systems.
How is the drain terminal thermally connected in the DFN0603-3 package?
The drain (Pin 3) is internally connected to the exposed bottom copper pad of the DFN0603-3 package. Per Figure 18 and Table 6, this pad must be soldered to a ≥1 cm² FR4 PCB copper area to achieve the specified Rth(j-sp) of 23–26.5 K/W and enable 4.7 W peak power dissipation.
