Product details
Overview
PMN48XP,125 from Nexperia is a P-channel enhancement-mode Trench MOSFET in SOT457 (TSOP6) package, rated for −20 V drain-source voltage, −4.1 A continuous drain current at 25 °C, and 48 mΩ typical RDS(on) at VGS = −4.5 V and ID = −2.4 A. It serves as a high-side load switch or high-speed line driver in compact power management circuits.
For engineers reviewing the PMN48XP,125 datasheet, PMN48XP,125 pinout, PMN48XP,125 application, or PMN48XP,125 equivalent, key selection criteria include its low gate charge (8.7 nC total), fast switching (tr/tf = 22 ns), thermal resistance of 84 K/W (with 6 cm² drain pad), and −1.0 V typical gate threshold voltage enabling robust logic-level drive compatibility.
Technical Context
This device uses Trench MOSFET technology to achieve low on-resistance and fast switching performance in a 6-lead surface-mount package. Its symmetrical drain configuration-four drain terminals (pins 1, 2, 5, 6)-enables enhanced thermal dissipation and current handling in high-density PCB layouts.
The PMN48XP,125 operates with a gate-source voltage range of ±12 V and exhibits stable RDS(on) up to 150 °C junction temperature (70–80 mΩ). Its source-drain diode has a forward voltage of −0.75 V at −2.4 A, supporting bidirectional current paths in certain switching topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | −20 V - Maximum blocking voltage for high-side switching in 12 V or 15 V rail systems |
| ID (continuous) | −4.1 A at Tamb = 25 °C - Supports moderate-power loads without external heatsinking under standard FR4 mounting |
| RDS(on) | 48 mΩ typ. at VGS = −4.5 V, ID = −2.4 A - Enables <100 mW conduction loss at 2 A load current |
| QG(tot) | 8.7 nC typ. - Reduces gate drive power and enables >1 MHz switching in PWM applications |
| tr/tf | 22 ns typ. - Supports clean edge transitions in high-speed digital interface and relay driving |
| VGS(th) | −1.0 V typ. - Ensures full enhancement with 3.3 V or 5 V logic-level gate drive |
| Rth(j-a) | 84 K/W with 6 cm² drain pad - Allows ~1.3 W power dissipation before reaching 150 °C junction limit |
Pinout & Package
SOT457 (TSOP6) plastic surface-mounted package with 6 leads; 1.1 mm × 2.7 mm footprint and 0.95 mm height; optimized for reflow soldering with exposed drain thermal pad layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Drain (D) | Four parallel drain connections provide low-inductance, high-current path and improved thermal spreading to PCB copper |
| 3 | Gate (G) | Control terminal requiring ≤12 V negative bias relative to source; low input capacitance (1000 pF) minimizes drive burden |
| 4 | Source (S) | Reference node for gate control; tied to system ground or positive rail depending on high-side vs. low-side configuration |
Key Features
| Feature | Design Value |
|---|---|
| Trench MOSFET architecture | Delivers 48 mΩ RDS(on) in ultra-small TSOP6 package, enabling space-constrained DC-DC and load-switch designs |
| Multi-drain pin configuration | Four dedicated drain pins reduce package inductance and improve thermal transfer to PCB, supporting higher peak currents |
| Low gate charge (8.7 nC) | Minimizes switching losses and gate driver stress in high-frequency (>500 kHz) applications such as LED drivers and motor control |
| Logic-level compatible VGS(th) | −1.0 V typical threshold ensures reliable turn-on with 3.3 V microcontroller GPIOs without level-shifting circuitry |
| Fast 22 ns rise/fall times | Reduces transition-time losses and EMI generation in high-speed switching nodes like USB power delivery and industrial I/O |
Applications

IC Role / Device Role / Timing Role: Secondary-side switch managing energy transfer timing and minimizing conduction loss. Use Value: 8.7 nC QG(tot) allows efficient gate drive with small-area gate resistors, and 150 °C max Tj supports operation in thermally constrained enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2011LFG-7 | −20 V, −4.2 A, 45 mΩ RDS(on), SOT-23-6 package; lower RDS(on) but smaller thermal pad area | Better conduction efficiency in space-limited designs; less effective heat spreading due to smaller drain pad | Select when board area is critical and peak power dissipation remains <0.8 W |
| SI2305-CDS | −20 V, −4.0 A, 55 mΩ RDS(on), SOT-23 package; single-drain configuration, higher Rth(j-a) (204 K/W) | Lower cost and smaller footprint, but limited to <0.5 W continuous dissipation without heatsinking | Select for low-duty-cycle or low-current (<1.5 A) applications where thermal margin is sufficient |
Compared with DMN2011LFG-7 and SI2305-CDS, the PMN48XP,125 offers superior thermal performance (84 K/W) and multi-drain layout for higher reliability in sustained-load scenarios, while maintaining competitive RDS(on) and gate drive compatibility.

FAQ
What is the maximum safe operating junction temperature for PMN48XP,125?
The absolute maximum junction temperature is 150 °C per the datasheet limiting values. Operation above this threshold risks permanent degradation of the MOSFET channel and gate oxide. Derating curves show that continuous power dissipation must be reduced linearly above 25 °C ambient, with 6250 mW allowed only at Tsp = 25 °C and full 6 cm² drain pad.
Can PMN48XP,125 be used with 3.3 V microcontroller GPIOs without a gate driver?
Yes - its typical VGS(th) of −1.0 V and guaranteed −1.25 V maximum ensure full enhancement at VGS = −3.3 V. At ID = −2.4 A, RDS(on) remains 48 mΩ (typ.), confirming robust conduction with direct 3.3 V logic drive, provided source is referenced to MCU ground.
How does the four-drain-pin configuration affect PCB layout and thermal design?
The four drain pins (1, 2, 5, 6) must be connected to a common large copper pour (≥6 cm²) to achieve the specified 84 K/W thermal resistance. Splitting or undersizing the drain pad increases Rth(j-a) to 204 K/W, limiting usable power to ~530 mW - a 90% reduction in thermal capacity.
Is PMN48XP,125 suitable for automotive applications?
No - the datasheet explicitly states it is a non-automotive qualified product. It lacks AEC-Q101 qualification, automotive-grade process controls, and extended temperature validation. For automotive use, Nexperia recommends AEC-Q101 qualified alternatives such as the PMN50XPE or NX3008PBK.
