Product details

Overview

PMPB12UNEAX from Nexperia is a 20 V, N-channel enhancement-mode Trench MOSFET in a DFN2020MD-6 (SOT1220) package, designed for low-side switching in automotive and industrial power control circuits. It delivers 7.9 A continuous drain current at V_GS = 4.5 V and 25 °C, with R_DS(on) of 13 mΩ (typ), 18 mΩ (max), and features AEC-Q101 qualification, side-wettable flanks, and >500 V HBM ESD protection.

For engineers reviewing the PMPB12UNEAX datasheet, PMPB12UNEAX pinout, PMPB12UNEAX application, or PMPB12UNEAX equivalent, key selection criteria include its low 0.65 V gate threshold voltage, thermal resistance of 70 K/W (junction-to-solder point), 32 A peak drain current capability, and suitability for high-speed line driving and relay control where compact footprint and optical solder inspection support are required.

Technical Context

This MOSFET employs Trench technology to achieve low R_DS(on) and fast switching performance, with gate charge parameters Q_G(tot) = 10.9–17 nC and Q_GD = 2.1 nC enabling efficient gate drive in 4.5 V logic-level systems. Its sub-threshold conduction is tightly controlled (V_GS(th) = 0.4–0.9 V), ensuring reliable turn-on across temperature.

The device integrates a robust intrinsic body diode (V_SD = 0.7–1.2 V at 1.5 A) with 10 ns reverse recovery time and 2 nC recovered charge, supporting synchronous rectification and freewheeling in DC-DC converters. Thermal design is supported by normalized derating curves showing 100% power capability up to 75 °C junction temperature on standard FR4.

Use Value: Eliminates contact wear and bounce, reduces PCB area by 70% vs. relay + driver IC solution, and supports PWM dimming for audible feedback suppression.

Use Scenario: Driving 50 Ω transmission lines in CAN FD or LIN bus interface circuits with fast edge rates.

IC Role / Device Role / Timing Role: Active termination switch enabling dynamic impedance matching and slew-rate control during bus arbitration.

Use Value: Achieves <25 ns rise/fall times with 2.1 nC Q_GD, minimizing signal reflection and electromagnetic emissions in high-speed serial links.

Low-Side Load Switch

Switching Power Supply

Use Scenario: Hot-swap and inrush current limiting for USB-C PD ports or auxiliary 12 V loads in infotainment head units.

IC Role / Device Role / Timing Role: Controlled power path switch with precise gate drive timing to limit dI/dt during turn-on.

Use Value: Supports soft-start via gate resistor tuning; 13 mΩ R_DS(on) limits voltage drop to <100 mV at 7 A, preserving downstream voltage regulation.

Use Scenario: Synchronous rectifier in 5 V/3 A buck converter for ADAS camera modules or radar sensors.

IC Role / Device Role / Timing Role: Secondary-side power switch replacing Schottky diode to reduce conduction loss and improve efficiency.

Use Value: Body diode V_SD = 0.7 V and trr = 10 ns enable clean commutation; 2 nC Q_r minimizes reverse recovery loss at 500 kHz switching.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel low-voltage power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2020LFG-7	R_DS(on) = 15.5 mΩ (min) at V_GS = 4.5 V; same DFN2020MD-6 package; no AEC-Q101 qualification.	Targeted at consumer and industrial power management, not automotive-grade reliability testing.	Select when AEC-Q101 is not required and tighter R_DS(on) tolerance is prioritized over automotive qualification.
PSMN2R0-25YLH	R_DS(on) = 2.0 mΩ at V_GS = 10 V; TO-252 package; higher gate charge (Q_G = 29 nC); requires 10 V drive.	Suited for high-current (>20 A), lower-frequency (<200 kHz) applications where thermal mass outweighs size constraints.	Choose for higher current density needs where board space allows TO-252 and gate drive supports 10 V logic.

Compared with DMN2020LFG-7, PMPB12UNEAX offers certified automotive reliability and lower gate threshold; versus PSMN2R0-25YLH, it trades absolute R_DS(on) for smaller footprint, lower gate drive voltage, and faster switching-making it optimal for space-constrained 4.5 V logic-controlled systems.

FAQ

What is the maximum continuous drain current for PMPB12UNEAX at 100 °C ambient temperature?

The maximum continuous drain current is 5 A at T_amb = 100 °C with the device mounted on an FR4 PCB using a 6 cm² drain pad. This reflects thermal derating due to reduced heat dissipation at elevated ambient temperatures, as defined in Table 5 (Limiting Values) of the datasheet.

Does PMPB12UNEAX support 3.3 V logic-level gate drive?

Yes. With a typical gate threshold voltage of 0.65 V and guaranteed turn-on at V_GS ≥ 2.5 V, the device fully enhances at 3.3 V gate drive, delivering R_DS(on) ≤ 22 mΩ at 7.1 A and 25 °C. This eliminates need for gate drivers in most microcontroller-based low-side switch designs.

How does the side-wettable flank feature benefit manufacturing?

The plated vertical sidewalls on pins 1–8 allow automated optical inspection (AOI) systems to verify solder fillet formation and wetting quality without requiring X-ray imaging. This reduces final-test cycle time and increases yield confidence in high-volume SMT lines handling automotive-grade assemblies.

Is the body diode suitable for synchronous rectification in DC-DC converters?

Yes. The intrinsic source-drain diode has V_SD = 0.7–1.2 V at 1.5 A and t_rr = 10 ns, with Q_r = 2 nC. These parameters support efficient synchronous rectification in 500 kHz buck converters, especially when paired with complementary high-side control to minimize shoot-through risk.
