Product details
Overview
PXP020-20QX from Nexperia is a P-channel enhancement-mode Trench MOSFET in MLPAK33 (SOT8002-1) package, designed for high-side load switching with −20 V drain-source rating, 16 mΩ RDS(on) at VGS = −4.5 V and ID = −7.7 A, and low −0.9 V typical gate threshold voltage - enabling efficient operation in battery-powered DC-DC converters and power management circuits.
For engineers reviewing the PXP020-20QX datasheet, PXP020-20QX pinout, PXP020-20QX application, or PXP020-20QX equivalent, this device is selected for compact high-side switch designs requiring low gate drive voltage, thermal robustness on FR4 PCBs, and fast switching with 6.2 nC QGD and 31 ns fall time under 5 Ω gate resistance.
Technical Context
This MOSFET uses Trench process technology to achieve low RDS(on) and tight VGS(th) distribution (−0.7 to −1.25 V), supporting reliable turn-on with logic-level gate drive down to −2.5 V. Its 8-terminal MLPAK33 package integrates four parallel drain leads and three parallel source leads to reduce package inductance and improve current sharing.
The device features an integrated body diode with −0.7 to −1.2 V forward voltage at −1.7 A, 26 ns reverse recovery time, and 10 nC recovered charge - suitable for synchronous rectification and freewheeling in buck converters where diode conduction occurs during dead-time intervals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | −20 V - Maximum blocking voltage for 12 V battery systems with margin against transients. |
| RDS(on) | 16 mΩ (typ) at VGS = −4.5 V - Enables <100 mW conduction loss at 7.7 A continuous current. |
| VGS(th) | −0.9 V (typ) - Ensures full enhancement with 1.8 V/2.5 V logic outputs without level-shifting. |
| QGD | 6.2 nC - Low gate-drain charge minimizes Miller-induced switching delay and improves EMI behavior. |
| ID (cont) | −12.1 A (t ≤ 5 s, FR4 PCB) - Supports peak load currents in portable power switches and hot-swap circuits. |
| Rth(j-sp) | 4–8 K/W - Low junction-to-solder-point thermal resistance enables direct thermal coupling to PCB copper pour. |
| tf | 31 ns - Fast fall time reduces switching losses in PWM frequencies up to 1 MHz. |
Pinout & Package
MLPAK33 (SOT8002-1) is a thermally enhanced 8-terminal surface-mount package measuring 3.3 × 3.3 × 0.8 mm, with 0.65 mm lead pitch, mini leads, and exposed drain paddle optimized for solder thermal transfer on FR4 PCBs with 6 cm² copper pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source (S) | Three parallel source terminals reduce source inductance and improve current sharing in high-di/dt switching. |
| 4 | Gate (G) | Single gate input with 6.4 Ω internal gate resistance - compatible with standard logic drivers without external gate resistor. |
| 5, 6, 7, 8 | Drain (D) | Four parallel drain terminals connect directly to thermal pad - maximize heat extraction and minimize power loop inductance. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel high-side switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT6009LPS-13 | −60 V VDS, 9.5 mΩ RDS(on) at −10 V, SO-8 package, higher gate charge (27 nC). | Requires −10 V gate drive; unsuitable for 3.3 V logic control without level shift. | Select only when higher voltage blocking or lower RDS(on) at −10 V is mandatory and gate drive voltage is available. |
| PSMN2R0-30YLC | −30 V VDS, 2.0 mΩ RDS(on) at −10 V, LFPAK56 package, 3× larger footprint (5.1 × 6.1 mm). | Higher thermal mass but slower switching (QGD = 14.5 nC); not pin-compatible. | Prefer for high-current (>20 A), low-frequency (<200 kHz) industrial loads where size is secondary to conduction loss. |
Compared with DMT6009LPS-13 and PSMN2R0-30YLC, PXP020-20QX trades absolute RDS(on) for logic-level compatibility, compact 3.3 mm² area, and faster switching - making it optimal for space-constrained, battery-fed systems operating below 15 V.

FAQ
What is the maximum continuous drain current for PXP020-20QX on a standard FR4 PCB?
The maximum continuous drain current is −12.1 A at Tamb = 25 °C with t ≤ 5 s, measured on FR4 PCB with single-sided 6 cm² copper pad for drain. At 100 °C ambient, derated current drops to −4.8 A per Figure 2 in the datasheet.
Can PXP020-20QX be driven directly by a 3.3 V microcontroller GPIO?
Yes - its −0.9 V typical VGS(th) and −1.25 V maximum ensure full enhancement at 3.3 V gate drive. RDS(on) remains 20 mΩ (max) at VGS = −3.3 V and ID = −5.8 A, verified in Table 7 characteristics.
How does the MLPAK33 package improve thermal performance over standard SO-8?
MLPAK33 achieves Rth(j-sp) of 4–8 K/W versus ~50 K/W for SO-8 due to direct copper connection between drain terminals and PCB thermal pad. This enables 15 W power dissipation at Tsp = 25 °C, compared to ~2.5 W for SO-8 under identical conditions.
Is the body diode suitable for reverse polarity protection?
Yes - the integrated source-drain diode has −0.7 to −1.2 V forward voltage at −1.7 A and 26 ns reverse recovery time. It supports reverse-current blocking in battery-input circuits, but external TVS is recommended for transient suppression above 20 V.
