Product details
Overview
PMPB19XP from Nexperia is a single P-channel enhancement-mode Trench MOSFET in a DFN2020MD-6 (SOT1220) package, rated for −20 V drain-source voltage, 19 mΩ typical RDS(on) at VGS = −4.5 V and ID = −7.2 A, and −10.3 A continuous drain current at Tamb = 25 °C. It serves as a high-efficiency charging switch or power rail control device in compact battery-powered systems.
For engineers reviewing the PMPB19XP datasheet, PMPB19XP pinout, PMPB19XP application, or PMPB19XP equivalent, this device is selected for low-voltage portable power management where ultra-thin SMD footprint, thermal performance via exposed drain pad, and verified sub-1 VGS(th) threshold are critical design requirements.
Technical Context
This P-channel MOSFET uses Trench technology to achieve low on-resistance and fast switching with gate charge QG(tot) of 28.8–43.2 nC and turn-on delay td(on) of 16 ns. Its gate-source threshold voltage ranges from −0.47 V to −0.9 V at Tj = 25 °C, enabling reliable turn-on with low-voltage logic-level drive.
The device features an integrated source-drain diode with VSD = −0.6 to −1.2 V at IS = −1.9 A and exhibits normalized RDS(on) drift of ≤1.75× from −60 °C to 150 °C. Thermal resistance from junction to solder point is 5–10 K/W, confirming suitability for PCB-constrained thermal designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | −20 V maximum - supports full operation across 3.3 V to 12 V battery rails without breakdown risk |
| RDS(on) | 19 mΩ typical at VGS = −4.5 V, ID = −7.2 A, Tj = 25 °C - enables <150 mW conduction loss at 7 A |
| ID (cont) | −7.2 A at Tamb = 25 °C - validated for sustained load switching in DC-DC output stages |
| VGS(th) | −0.68 V typical - ensures robust turn-on with 1.8 V or 2.5 V GPIO control without level-shifting |
| QG(tot) | 28.8–43.2 nC - balances switching speed and gate driver loading in high-frequency (>1 MHz) buck controllers |
| Rth(j-sp) | 5–10 K/W - allows direct thermal coupling to PCB copper, supporting >1.5 W dissipation with minimal heatsinking |
| Ciss | 2890 pF - defines input capacitance seen by gate driver; impacts rise/fall time under 6 Ω external gate resistance |
Pinout & Package
DFN2020MD-6 (SOT1220) is a 2.0 × 2.0 × 0.65 mm leadless ultra-thin plastic package with exposed drain pad for thermal conduction and tin-plated side terminals for optical solder inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 7 | Drain (D) | Five parallel drain terminals connected to internal die and exposed thermal pad - primary current path and thermal interface |
| 3 | Gate (G) | Single gate input terminal - requires ESD-safe handling and controlled slew rate to avoid oscillation |
| 4, 8 | Source (S) | Two source terminals tied to internal source metallization - forms return path for load current and reference for gate drive |
Key Features
| Feature | Design Value |
|---|---|
| Trench MOSFET architecture | Enables 19 mΩ RDS(on) in 2 mm² footprint - reduces board area vs. SO-8 or TSOP6 alternatives |
| Exposed drain pad | Reduces Rth(j-sp) to 5–10 K/W - improves thermal margin in sealed portable enclosures |
| Tin-plated side pads | Supports automated optical inspection (AOI) of solder joints - increases manufacturing yield in high-volume assembly |
| Ultra-thin 0.65 mm profile | Enables stacking in space-constrained modules (e.g., USB-C PD adapters, wearable battery packs) |
Applications
| Charging Switch | DC-DC Converter High-Side Switch |
|---|---|
|

IC Role / Device Role / Timing Role: Power FET in non-isolated step-down regulator delivering up to 7 A to SoC or PMIC rails. Use Value: 43.2 nC max QG(tot) supports efficient 1–2 MHz switching; low Coss (250 pF) minimizes dead-time losses. |
| Battery Management System | Hard Disk Drive Power Control |
|
Use Scenario: Isolation of auxiliary rails (e.g., display backlight, sensor array) during deep sleep mode. IC Role / Device Role / Timing Role: Low-leakage power gating switch with IDSS ≤ −1 µA at −20 V, reducing standby current. Use Value: Gate leakage <100 nA at −12 V ensures stable off-state over temperature; 150 °C Tj(max) supports industrial ambient. |

IC Role / Device Role / Timing Role: Hard-switched power rail controller activated only after system reset and voltage stabilization. Use Value: −30 A peak drain current (tp ≤ 10 µs) withstands HDD inrush; 1.7 W Ptot supports brief surge loads without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305UVT-7 | RDS(on) = 42 mΩ @ VGS = −4.5 V; smaller 1.6 × 1.6 mm package; higher VGS(th) (−1.0 to −2.5 V) | Lower current capability (−4.2 A); suited for <3 A loads where size is more critical than conduction loss | Select when board area is constrained below 3.2 mm² and load current remains ≤4 A |
| SI2301DDS-T1-BE3 | RDS(on) = 115 mΩ @ VGS = −4.5 V; same SOT-23 footprint; lower cost; no exposed drain pad | Higher conduction loss (>800 mW at 7 A); limited thermal capacity (Rth(j-a) ≈ 200 K/W) | Select for cost-sensitive, low-power (<1 A), non-thermal-critical applications where legacy SOT-23 layout reuse is required |
Compared with DMG2305UVT-7 and SI2301DDS-T1-BE3, PMPB19XP delivers 2.2× lower RDS(on) than the former and 6× lower than the latter while maintaining thermal reliability via its exposed drain pad - making it optimal for 5–10 A portable power switches where efficiency and thermal headroom are prioritized.

FAQ
What is the maximum continuous drain current for PMPB19XP at 100 °C ambient temperature?
The maximum continuous drain current for PMPB19XP is −4.5 A at Tamb = 100 °C, as specified in Table 5 (Limiting values). This derating reflects thermal constraints of the DFN2020MD-6 package on standard FR4 PCB with 6 cm² drain pad, ensuring safe operation within its 150 °C junction limit.
Does PMPB19XP require a gate resistor for stability in switching applications?
Yes - a gate resistor (typically 1–10 Ω) is recommended to dampen ringing caused by gate loop inductance and the device's 2890 pF Ciss. The datasheet specifies switching times (e.g., tr = 54 ns, tf = 36 ns) using RG(ext) = 6 Ω, confirming that external gate resistance directly controls edge rates and EMI.
Can PMPB19XP be used in automotive applications?
No - PMPB19XP is not automotive-qualified. The datasheet explicitly states "Non-automotive qualified products" in Section 12.3 and does not list AEC-Q101 qualification. Its guaranteed operating range (−55 °C to 150 °C) supports industrial use but lacks automotive-specific stress testing, failure analysis, and PPAP documentation.
How is thermal performance affected if the PCB drain pad is reduced below 6 cm²?
Reducing the drain pad below 6 cm² significantly degrades thermal performance: Rth(j-a) increases from 67–74 K/W (6 cm²) to 235–270 K/W (standard footprint), lowering maximum allowable power dissipation from 1.7 W to ~0.3 W at 25 °C ambient. This necessitates strict current derating or active cooling in compact layouts.
