Product details
Overview
PMPB24EPX from Nexperia is a 30 V, P-channel enhancement-mode Trench MOSFET in a DFN2020MD-6 (SOT1220) package, designed for high-efficiency power switching in space-constrained portable electronics. It delivers 24 mΩ RDS(on) at VGS = −10 V and ID = −6.4 A (Tj = 25 °C), supports logic-level gate drive down to −4.5 V, and features an exposed drain pad for thermal conduction in battery-powered DC-DC converters and charging switches.
For engineers reviewing the PMPB24EPX datasheet, PMPB24EPX pinout, PMPB24EPX application, or PMPB24EPX equivalent, key selection criteria include its 24 mΩ on-resistance at −10 V gate drive, side-wettable flanks for automated optical solder inspection, 6.4 A continuous drain current rating on FR4 PCB, and compatibility with compact 2 × 2 × 0.65 mm layouts in portable power management systems.
Technical Context
This P-channel MOSFET uses Trench technology to achieve low RDS(on) and fast switching with QG(tot) = 19–28 nC and tf = 14 ns under standard test conditions. Its gate threshold voltage (VGS(th)) ranges from −1.0 V to −2.5 V at ID = −250 µA, enabling reliable turn-on with common 3.3 V or 5 V logic controllers.
The device integrates six terminals in a thermally enhanced DFN2020MD-6 package: five drain connections (pins 1, 2, 5, 6, 7) and two source connections (pins 4, 8), with a single gate terminal (pin 3). Thermal resistance from junction to solder point is as low as 4–8 K/W, supporting high-power-density designs without external heatsinking.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | RDS(on) = 28 mΩ @ −10 V; SO-8 package; 5.15 × 6.2 mm footprint | Larger board area; higher thermal resistance (Rth(j-a) ≈ 62 K/W); no side-wettable flanks | Select when legacy SO-8 layout reuse is prioritized over size/thermal performance |
| SI2301DS-T1-BE3 | RDS(on) = 115 mΩ @ −4.5 V; SOT-23 package; 2.9 × 1.6 mm but lower current rating (−2.7 A) | Lower cost but unsuitable for >3 A loads; lacks exposed drain pad and wettable flanks | Select only for ultra-low-cost, sub-2 A load switching where thermal margin is ample |
Compared with DMN3026LSD-13 and SI2301DS-T1-BE3, PMPB24EPX offers superior current density (6.4 A in 4 mm² vs. 5.1 A in 32 mm² or 2.7 A in 4.6 mm²), lower thermal resistance, and AOI-compatible packaging-making it optimal for next-generation compact, thermally constrained power rails.

FAQ
What is the maximum continuous drain current for PMPB24EPX at 100 °C ambient temperature?
The maximum continuous drain current is −4.1 A at Tamb = 100 °C with the device mounted on an FR4 PCB having a 6 cm² drain pad. This derating reflects thermal limitations under sustained high-temperature operation and must be verified against actual board layout and airflow conditions.
Does PMPB24EPX require a gate resistor for ESD protection or switching control?
No external gate resistor is required for ESD protection-the device incorporates built-in gate protection diodes. However, a 1–10 Ω series resistor is recommended between driver and gate to dampen ringing and control dV/dt during switching, especially in high-frequency DC-DC applications.
Can PMPB24EPX be used in reverse polarity protection circuits?
Yes-its P-channel configuration and −30 V VDS rating make it suitable for reverse polarity protection at input voltages up to 24 V. When placed in the high-side position with gate tied to input, it blocks reverse current while maintaining low forward drop during normal operation.
Is the DFN2020MD-6 package compatible with standard reflow soldering profiles?
Yes-the package is qualified for IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C. The recommended footprint (per Figure 19) uses 0.35 mm wide solder lands and 0.25 mm solder paste stencil openings to ensure reliable side-wettable flank formation.
