Product details
Overview
PMPB8XN from Nexperia is a 20 V, N-channel enhancement-mode Trench MOSFET in a DFN2020MD-6 (SOT1220) package, designed for low-side load switching with RDS(on) = 8.5 mΩ at VGS = 4.5 V and ID = 10.1 A, 14.3 A continuous drain current capability, and side-wettable flanks for automated optical solder inspection - deployed in high-speed line drivers and relay driver circuits.
For engineers reviewing the PMPB8XN datasheet, PMPB8XN pinout, PMPB8XN application, or PMPB8XN equivalent, key selection criteria include its 20 V VDS rating, sub-1 V gate threshold (VGS(th) = 0.65 V typ), thermal resistance Rth(j-sp) = 6–10 K/W to solder point, 20–30 nC total gate charge, and compatibility with 1.5–4.5 V logic-level drive in space-constrained PCB layouts.
Technical Context
This N-channel MOSFET uses Trench technology to achieve low on-resistance and fast switching (td(on) = 5 ns, tf = 15 ns) while maintaining robust safe operating area (SOA) up to 40 A peak drain current. Its drain-source breakdown voltage is fixed at 20 V with tight VGS(th) distribution (0.4–0.9 V).
The device integrates an exposed drain pad for direct thermal conduction to PCB copper, supported by validated thermal metrics: Rth(j-a) = 57–66 K/W on 6 cm² drain pad, and normalized power derating curves across −55 °C to 150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 20 V - Maximum blocking voltage before avalanche; defines use in ≤20 V rail systems. |
| RDS(on) | 8.5 mΩ @ VGS = 4.5 V, ID = 10.1 A, Tj = 25 °C - Enables <100 mW conduction loss at 10 A. |
| VGS(th) | 0.65 V typ - Ensures reliable turn-on with 1.8 V GPIO or low-voltage microcontrollers. |
| QG(tot) | 20–30 nC - Determines gate drive power and switching speed in PWM applications. |
| ID cont | 14.3 A @ Tamb = 25 °C, t ≤ 5 s - Sustains high pulsed loads without thermal runaway on standard FR4. |
| Rth(j-sp) | 6–10 K/W - Quantifies junction-to-solder-point thermal path efficiency for layout-aware thermal design. |
| Ciss | 1696 pF - Impacts high-frequency gate drive impedance and EMI behavior in switching nodes. |
Pinout & Package
DFN2020MD-6 (SOT1220) is a 2.0 × 2.0 × 0.65 mm ultra-thin leadless package with exposed drain pad, side-wettable flanks, and six terminals - optimized for automated optical inspection and high-power density PCB mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 7 | Drain (D) | Five parallel drain terminals connected to internal die and exposed pad - provides low-inductance, high-current path and primary thermal conduction route. |
| 3 | Gate (G) | Single control terminal requiring <30 nC charge; sensitive to ESD but compatible with 1.5–8 V logic drive. |
| 4, 8 | Source (S) | Two source terminals tied to source metallization - forms return path for load current and reference for gate drive. |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables AOI-compatible solder joint verification without X-ray - critical for automotive and industrial production traceability. |
| Exposed drain pad | Reduces Rth(j-sp) to 6–10 K/W - allows >12 W power dissipation with minimal board area (6 cm² copper pad). |
| Trench MOSFET architecture | Delivers 8.5 mΩ RDS(on) at 4.5 V drive - eliminates need for gate boosters in 3.3 V/5 V systems. |
| Low VGS(th) | 0.65 V typical threshold - ensures full enhancement with 1.8 V I/O, supporting modern ultra-low-voltage MCUs. |
| Fast switching | td(on) = 5 ns, tf = 15 ns - minimizes transition losses in high-frequency (>1 MHz) DC-DC and motor gate drivers. |
Applications
| Relay Driver | High-Speed Line Driver |
|---|---|

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 | RDS(on) = 10.5 mΩ @ 4.5 V; QG = 23 nC; same DFN2020MD-6 package | Slightly higher conduction loss; identical footprint and pinout | Select when prioritizing supply chain diversity over marginal RDS(on) reduction. |
| SI2302DS-T1-BE3 | RDS(on) = 50 mΩ @ 4.5 V; SOT-23 package; lower current rating (3 A) | Not suitable for >5 A loads; lacks side-wettable flanks and thermal pad | Only consider for cost-sensitive, low-current (<3 A), non-AOI production environments. |
Compared with DMN2020LFG-7 and SI2302DS-T1-BE3, PMPB8XN delivers superior thermal performance via its exposed drain pad and lowest RDS(on) in the DFN2020MD-6 form factor - making it optimal for high-current, high-reliability, AOI-verified designs.

FAQ
What is the maximum continuous drain current for PMPB8XN at 100 °C ambient temperature?
The maximum continuous drain current for PMPB8XN is 6.4 A at Tamb = 100 °C, as specified in Table 5 (Limiting values) under conditions of VGS = 4.5 V and device mounted on FR4 PCB with 6 cm² drain pad. This reflects thermal derating due to reduced heat dissipation at elevated ambient temperatures.
Does PMPB8XN support logic-level gate drive from a 1.8 V microcontroller?
Yes - PMPB8XN has a typical gate threshold voltage of 0.65 V and guaranteed maximum of 0.9 V, enabling full enhancement with 1.8 V GPIO. Its RDS(on) remains 16 mΩ at VGS = 1.8 V and ID = 3.7 A (Table 7), confirming robust low-voltage operation.
How does the side-wettable flank feature improve manufacturing yield?
The side-wettable flanks on the DFN2020MD-6 package allow automated optical inspection (AOI) systems to verify solder fillet formation on all six terminals - eliminating reliance on X-ray for hidden-joint validation and reducing false-call rates in high-volume SMT lines by >95%.
What is the safe operating area (SOA) limitation for single-pulse operation?
At Tsp = 25 °C, the SOA curve (Figure 3) shows PMPB8XN supports 40 A peak drain current at VDS ≤ 5 V for pulse widths ≤10 µs. At VDS = 10 V, the limit drops to ~15 A for the same pulse width - defined by both thermal inertia and bondwire current capacity.
