Product details

Overview

PMPB20XNEA 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 R_DS(on) = 16 mΩ at V_GS = 4.5 V and I_D = 7.5 A (T_j = 25 °C), supports 30 A peak drain current, and is AEC-Q101 qualified for automotive reliability.

For engineers reviewing the PMPB20XNEA datasheet, PMPB20XNEA pinout, PMPB20XNEA application, or PMPB20XNEA equivalent, this device is selected for high-speed line driving, relay control, and thermally constrained low-voltage load switching where low threshold voltage (V_GS(th) = 1.0 V typ), fast switching (t_r = 40 ns), and ESD robustness (>2 kV HBM) are critical.

Technical Context

This MOSFET employs Trench technology to achieve low on-resistance and fast switching with minimal gate charge (Q_G(tot) = 9.9 nC typ). Its 6-terminal DFN2020MD-6 package features five drain terminals and one source terminal-optimized for thermal performance via a large copper drain pad (6 cm² on FR4).

The device operates with a gate-source threshold voltage of 0.75–1.25 V and supports gate drive down to 2.5 V, enabling compatibility with 3.3 V logic. Its safe operating area (SOA) is defined up to 100 ms pulses at V_DS = 10 V and I_D = 7.5 A, with normalized power derating to 12.5 W at T_sp = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	20 V maximum - defines absolute upper limit for drain-source blocking in low-voltage systems (e.g., 12 V automotive rails)
R_DS(on)	16 mΩ typ at V_GS = 4.5 V, I_D = 7.5 A - enables <100 mW conduction loss at 7.5 A, critical for thermally limited PCB layouts
Q_G(tot)	9.9 nC typ - reduces gate drive power and speeds turn-on/turn-off transitions in PWM applications
t_r/t_f	40 ns / 22 ns - supports >1 MHz switching frequencies in DC-DC converters and motor drivers
V_GS(th)	1.0 V typ - ensures reliable turn-on with 3.3 V microcontroller GPIO without level-shifting
T_j max	150 °C - allows operation in under-hood automotive environments with appropriate thermal design
ESD HBM	2000 V - provides robust handling during board assembly and system integration without external protection

Pinout & Package

DFN2020MD-6 (SOT1220) is a 2.0 × 2.0 × 0.65 mm leadless thermal-enhanced plastic package with exposed drain paddle. Five terminals connect to drain (pins 1, 2, 5, 6, 7), one to gate (pin 3), and two to source (pins 4 and 8).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6, 7	Drain	Five parallel drain connections maximize current handling and reduce package inductance; all tied to internal die drain metallization
3	Gate	Single gate input with low RG (1 Ω typ); requires <10 nC total charge for full enhancement
4, 8	Source	Dual source terminals improve current distribution and reduce source inductance in high-di/dt switching

Key Features

Feature	Design Value
Low threshold voltage	V_GS(th) = 0.75–1.25 V enables direct drive from 3.3 V logic without gate driver ICs
Fast switching	t_r = 40 ns and t_f = 22 ns minimize switching losses in high-frequency SMPS and Class-D amplifiers
AEC-Q101 qualification	Validated for automotive temperature range (−40 °C to +150 °C) and mechanical stress per JESD22 standards
ESD protection	HBM rating >2 kV eliminates need for external ESD diodes in most board-level implementations
Thermal-enhanced DFN	R_th(j-sp) = 5–10 K/W enables 12.5 W dissipation with solder-point cooling - 2× better than standard SOT-23

Applications

IC Role / Device Role / Timing Role: Low-side switch controlling relay coil current (≤500 mA) with fast turn-off to suppress back-EMF spikes.

Use Value: 1.0 V V_GS(th) ensures reliable activation at cold-cranking voltages (down to 6 V battery), while 22 ns fall time limits coil energy dissipation.

Use Scenario: Transmitting TTL/CMOS signals across noisy factory-floor cables in PLC I/O modules.

IC Role / Device Role / Timing Role: Active pull-down stage in a push-pull line driver configuration, sinking up to 7.5 A transient loads.

Use Value: 16 mΩ R_DS(on) minimizes voltage drop during signal low-state, preserving noise margin; 40 ns rise time maintains signal integrity at 10 Mbps.

USB-C Power Delivery Load Switch

Use Scenario: Enabling/disabling 5–20 V USB-C power paths in portable docking stations.

IC Role / Device Role / Timing Role: Inrush-limited low-side power switch with controlled turn-on via RC gate network.

Use Value: 20 V V_DS rating covers full USB PD 3.0 range; 30 A peak current handles hot-plug surge without latch-up.

Use Scenario: PWM dimming of white LED strings (3–18 V forward) in automotive instrument clusters.

IC Role / Device Role / Timing Role: Synchronous low-side switch in constant-current LED driver topology.

Use Value: Fast 40 ns/22 ns switching reduces PWM dead-time distortion; 150 °C T_j max supports sealed enclosure operation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2020LFG-7	R_DS(on) = 20 mΩ @ 4.5 V; Q_G = 11.5 nC; same DFN2020MD-6 package	Slightly higher conduction loss; identical footprint and thermal profile	Select when lower gate charge is not required and cost sensitivity favors Diodes Inc. sourcing
SI2302DS-T1-BE3	R_DS(on) = 35 mΩ @ 4.5 V; Q_G = 5.2 nC; SOT-23 package (R_th(j-a) = 235 K/W)	Higher on-resistance and worse thermal resistance limit continuous current to ≤3 A	Choose only for space-constrained non-automotive designs where peak current <3 A and board area is premium

Compared with DMN2020LFG-7, PMPB20XNEA offers 20% lower R_DS(on) and faster switching, improving efficiency in high-duty-cycle loads; versus SI2302DS-T1-BE3, its DFN2020MD-6 package delivers 4× better thermal performance and 2.5× higher continuous current capability.

FAQ

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

The PMPB20XNEA supports 4.8 A continuous drain current at T_amb = 100 °C with standard FR4 mounting (single-sided copper, 6 cm² drain pad). This value is derived from thermal derating curves in Figure 2 of the datasheet and assumes no forced airflow or heatsinking.

Does the DFN2020MD-6 package require special PCB layout considerations?

Yes - the DFN2020MD-6 requires a dedicated thermal pad (6 cm² minimum) connected to a solid copper pour for drain terminals. Figure 19 specifies exact solder land dimensions (0.65 × 0.65 mm per pad, 0.25 mm gap), and solder paste volume must be controlled to prevent voiding beneath the exposed drain paddle.

Is gate resistor selection critical for reliable operation?

Yes - a 6 Ω external gate resistor is used in the datasheet's dynamic test conditions (t_d(off), t_f). Lower values (<2 Ω) risk ringing and overshoot due to low gate resistance (1 Ω typ) and parasitic inductance; higher values (>10 Ω) increase switching losses and slow response in PWM applications.

How does the device behave under unclamped inductive switching?

The PMPB20XNEA sustains 13 mJ non-repetitive avalanche energy (E_AS) at T_j(init) = 25 °C with I_D = 1.3 A. This rating applies only to single-pulse events; repetitive avalanche is not characterized and must be avoided through proper snubber design or clamping.
