Product details
Overview
PMCM4402UPEZ from Nexperia is a P-channel enhancement-mode Trench MOSFET in a 4-bump WLCSP package (0.78 × 0.78 × 0.35 mm), rated for −20 V drain-source voltage, −4.2 A continuous drain current at VGS = −4.5 V and 25 °C, with RDS(on) of 65 mΩ (typ) under same conditions. It serves as a compact high-side load switch in space-constrained battery-powered systems.
For engineers reviewing the PMCM4402UPEZ datasheet, PMCM4402UPEZ pinout, PMCM4402UPEZ application, or PMCM4402UPEZ equivalent, key selection criteria include ultra-low-profile WLCSP packaging, sub-1 V gate threshold (−0.6 V typ), ESD robustness (>2 kV HBM), and thermal performance on FR4 PCBs with 6 cm² drain pad.
Technical Context
This device uses Trench MOSFET technology to achieve low RDS(on) and fast switching (td(on) = 4 ns, tf = 11 ns) with minimal gate charge (QG(tot) = 6.2 nC typ). Its symmetrical dual-source configuration (A2 and B2 pins) supports low-inductance layout in high-speed line driver applications.
The −0.6 V typical VGS(th) enables direct interface with 1.8 V and 2.5 V logic, while its −20 V VDS rating and −13 A peak drain current support robust operation in portable power rail switching. Thermal resistance Rth(j-sp) is 5–10 K/W, enabling efficient heat transfer to the PCB solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | −20 V - Maximum blocking voltage for battery-switch and high-side loadswitch circuits |
| RDS(on) | 65 mΩ (typ) at VGS = −4.5 V, ID = −3 A, Tj = 25 °C - Enables <100 mW conduction loss at 3 A |
| VGS(th) | −0.6 V (typ) at ID = −250 µA - Supports direct drive from low-voltage I/O without level shifting |
| QG(tot) | 6.2 nC (typ) - Reduces gate drive power and enables >1 MHz switching in DC-DC and load-switching |
| ESD Rating | >2 kV HBM - Ensures robust handling during board assembly and end-user integration |
| Ptot | 1.3 W at Tamb = 25 °C (FR4, 6 cm² drain pad) - Defines maximum steady-state power dissipation in standard PCB layout |
| tf | 11 ns (VDS = −10 V, ID = −3.3 A, RG(ext) = 6 Ω) - Critical for minimizing switching losses in high-frequency load control |
Pinout & Package

IC Role / Device Role / Timing Role: Discrete loadswitch replacing integrated PMIC channel where timing independence and low quiescent current are required. Use Value: IDSS leakage <1 µA at −20 V ensures <1 µA off-state current - extends shelf life of pre-charged medical devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel loadswitch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NX3008PBK | Same WLCSP4 package, but −30 V VDS, 100 mΩ RDS(on) at −4.5 V - higher voltage margin, higher on-resistance | Better suited for 24 V industrial sensors; less efficient in 3.3 V/5 V battery systems due to higher conduction loss | Select when system requires >20 V fault tolerance and can accept 50 % higher RDS(on) |
| DMN2020LSD | SO-8 package, −20 V, 42 mΩ RDS(on) at −4.5 V - lower on-resistance but 5× larger footprint (5 mm × 6 mm) | Preferred for prototyping and higher-power applications where thermal mass and manual rework matter more than size | Choose when board space permits and thermal design requires higher Ptot (>2 W) capability |
Compared with NX3008PBK, PMCM4402UPEZ offers 35 % lower RDS(on) in identical package size, improving efficiency in space-critical 3.3 V systems; versus DMN2020LSD, it trades 58 % smaller footprint for 55 % higher RDS(on), favoring miniaturization over raw power handling.

FAQ
What is the maximum continuous drain current for PMCM4402UPEZ at 100 °C ambient?
The maximum continuous drain current is −2.1 A at Tamb = 100 °C with VGS = −4.5 V, as specified in Table 5 (Limiting values). This derating reflects thermal limits on an FR4 PCB with 6 cm² drain pad; actual current depends on board layout and airflow.
Does PMCM4402UPEZ require a gate resistor for stable switching?
A gate resistor is recommended to dampen ringing and control slew rate. With QG(tot) = 6.2 nC and typical gate drive impedance, a 6 Ω external resistor (as used in the fall-time test condition) provides optimal trade-off between speed and EMI; omitting it may cause overshoot in high-dI/dt layouts.
Can PMCM4402UPEZ be used in automotive applications?
No - this part is not AEC-Q200 qualified and lacks automotive-grade qualification, reliability testing, or extended temperature validation beyond −55 °C to +150 °C junction range. Nexperia explicitly states non-automotive qualification in Section 15 of the datasheet.
How is thermal performance affected if the drain pad area is reduced below 6 cm²?
Rth(j-a) increases significantly: from 250–300 K/W (6 cm²) to 70–85 K/W (1 cm², 4-layer PCB) per Table 6. At 2 cm², Ptot derates to ~0.5 W at 25 °C ambient - users must recalculate safe operating area using Fig. 2 and Fig. 4 curves for their exact layout.
