Product details
Overview
PMDPB55XPAX from Nexperia is a dual P-channel enhancement-mode Trench MOSFET in a DFN2020-6 (SOT1118) package, designed for high-side load switching and DC-DC conversion. It delivers −20 V VDS, 50 mΩ RDS(on) at VGS = −4.5 V per channel, −3.6 A continuous drain current, AEC-Q101 qualification, and an ultra-thin 2 × 2 × 0.65 mm footprint.
For engineers reviewing the PMDPB55XPAX datasheet, PMDPB55XPAX pinout, PMDPB55XPAX application, or PMDPB55XPAX equivalent, this device supports automotive-grade high-speed switching circuits where low gate threshold (−0.65 V typ), fast turn-on delay (11 ns), and thermal-enhanced exposed drain pad are critical selection criteria.
Technical Context
This dual P-channel MOSFET integrates two independent trench-based transistors in a single leadless DFN package with shared thermal pad. Each channel operates with symmetric gate control, enabling synchronous high-side switching or complementary load management without external level-shifting circuitry.
Its −0.65 V typical VGS(th), 8.8 nC total gate charge, and 2.4 nC QGD support efficient PWM operation up to several MHz in compact power stages. The device's 107 K/W Rth(j-sp) (with 6 cm² drain pad) enables >1.2 W power dissipation at ambient temperatures up to 100 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | −20 V - Maximum drain-source blocking voltage per transistor; defines safe operating range in 12 V automotive and 15 V industrial rails. |
| RDS(on) | 50 mΩ (typ) at VGS = −4.5 V, ID = −3.6 A - Enables <180 mW conduction loss per channel at rated current, critical for thermally constrained PCBs. |
| QG(tot) | 8.8 nC (typ) - Low gate charge reduces driver power demand and supports <100 ns total switching transitions in high-frequency converters. |
| VGS(th) | −0.65 V (typ) - Ensures reliable turn-on with 3.3 V logic-level gate drive, eliminating need for dedicated gate boosters in low-voltage systems. |
| ID (cont) | −3.6 A per transistor at Tamb = 25 °C - Sustains full-rated current in standard FR4 layouts with minimal copper area, verified under AEC-Q101 stress conditions. |
| td(on) | 11 ns (typ) - Short turn-on delay enables precise timing control in synchronous buck topologies and fast load-switch sequencing. |
| Rth(j-sp) | 107 K/W (typ) with 6 cm² drain pad - Direct thermal path to PCB allows >1.2 W steady-state power handling without heatsinks in space-constrained modules. |
Pinout & Package
DFN2020-6 (SOT1118) is a 2 mm × 2 mm × 0.65 mm leadless plastic package with exposed drain pad for thermal conduction. The package complies with IPC-7351B standard land pattern and supports reflow soldering per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | S1 | Source terminal of transistor 1 - Connected to local ground or return path for first channel; electrically isolated from S2. |
| 2 | G1 | Gate terminal of transistor 1 - Requires clean, low-inductance drive; decoupling capacitor recommended near pin. |
| 3 | D2 | Drain terminal of transistor 2 - Shared with thermal pad; must be routed to high-current power net with adequate copper pour. |
| 4 | S2 | Source terminal of transistor 2 - Independent return path for second channel; not internally connected to S1. |
| 5 | G2 | Gate terminal of transistor 2 - Fully independent control input; supports asynchronous or synchronized dual-channel operation. |
| 6 | D1 | Drain terminal of transistor 1 - Electrically tied to exposed thermal pad; primary current path for first channel. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS power domains per stress test requirements. |
| Exposed drain pad | Thermal resistance reduced by >50% vs. standard DFN; enables 1.2 W continuous dissipation on 6 cm² FR4 copper without thermal vias. |
| Trench MOSFET technology | Delivers 20% lower RDS(on) and 30% faster switching than planar P-channel equivalents at same voltage rating. |
| Ultra-thin 0.65 mm profile | Enables stacking in multi-layer modules and integration into height-sensitive consumer and infotainment assemblies. |
| Low VGS(th) | −0.65 V typical threshold ensures robust turn-on with 3.3 V microcontroller GPIOs, reducing BOM count and layout complexity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMC2038LSD-13 | −20 V, 44 mΩ RDS(on), SO-8 package, non-AEC-Q101 | Larger footprint (5 × 6 mm), higher thermal resistance (160 K/W), no automotive qualification | Select when board space permits larger package and AEC-Q101 is not required; offers marginally lower RDS(on). |
| PSMN2R0-30PL,115 | −30 V, 2.0 mΩ RDS(on), LFPAK56 package, AEC-Q101 | Higher voltage rating increases cost and gate charge (29 nC); requires larger gate driver due to 2.0 V VGS(th) | Select only if system requires >20 V blocking capability; otherwise over-specified for 12 V automotive use cases. |

FAQ
Is PMDPB55XPAX pin-compatible with other DFN2020-6 dual MOSFETs?
No-PMDPB55XPAX uses a unique pinout (S1-G1-D2-S2-G2-D1) optimized for dual high-side switching. Competing DFN2020-6 dual P-MOSFETs like DMP2035U have different pin assignments (e.g., G1-S1-D1-G2-S2-D2), making direct replacement impossible without PCB redesign.
What is the maximum continuous drain current per channel at 100 °C ambient?
At Tamb = 100 °C with 6 cm² drain pad copper, the maximum continuous drain current per channel is −2.3 A, as specified in Table 5 (Limiting Values) of the datasheet. This reflects derating due to thermal resistance and junction temperature limits.
Does PMDPB55XPAX include integrated ESD protection?
Yes-PMDPB55XPAX features built-in HBM ESD protection rated at ±2 kV (Class 2 per JESD22-A114), verified during AEC-Q101 qualification. No external ESD diodes are required for typical automotive interface protection.
Can both channels operate independently with separate gate drives?
Yes-G1 and G2 are fully isolated terminals with no internal connection. Each gate can be driven independently using separate controllers or level-shifted signals, enabling asymmetric duty cycles, staggered switching, or fault-isolated operation per channel.
