Product details
Overview
PHP152NQ03LTA from NXP Semiconductors (formerly Philips Semiconductors) is a logic-level N-channel TrenchMOS™ power MOSFET in TO-220AB (SOT78) package, rated for VDS = 25 V, ID = 75 A (DC), RDS(on) ≤ 4 mΩ at VGS = 10 V and Tj = 25 °C, and Ptot = 150 W - optimized for high-efficiency DC-to-DC converters and switched-mode power supplies.
For engineers reviewing the PHP152NQ03LTA datasheet, PHP152NQ03LTA pinout, PHP152NQ03LTA application, or PHP152NQ03LTA equivalent, key selection criteria include logic-level gate drive compatibility (VGS(th) = 1–2 V), low thermal resistance (Rth(j-mb) = 1 K/W), avalanche ruggedness (EDS(AL)S = 560 mJ), and surface-mount vs. through-hole package variants.
Technical Context
This device uses TrenchMOS™ technology to achieve low RDS(on) and low gate charge (Qg(tot) = 36 nC), enabling fast switching with reduced conduction and switching losses. Its logic-level threshold (VGS(th) = 1.5 V typ.) allows direct drive from 3.3 V or 5 V microcontrollers without level-shifting circuitry.
The integrated source-drain diode supports synchronous rectification and freewheeling operation, with VSD = 0.85–1.2 V at IS = 25 A and trr = 50 ns. Thermal design leverages the mounting base (connected to drain) for efficient heat transfer, with Rth(j-mb) = 1 K/W and Rth(j-a) = 60 K/W in vertical still air.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 25 V - maximum continuous drain-source voltage; defines safe operating range in low-voltage power rails (e.g., 12 V/24 V systems). |
| RDS(on) | 3.4 mΩ (typ.) at VGS = 10 V, Tj = 25 °C - enables <1 W conduction loss at 50 A, critical for high-current DC-DC stages. |
| ID (DC) | 75 A at Tmb = 25 °C - supports high-current load switching in SMPS primary/secondary side or motor drive half-bridges. |
| Qg(tot) | 36 nC - low total gate charge reduces driver power demand and switching transition time, improving efficiency at >100 kHz. |
| Rth(j-mb) | 1 K/W - junction-to-mounting-base thermal resistance enables direct heatsink coupling for stable thermal management under sustained load. |
| EDS(AL)S | 560 mJ - non-repetitive avalanche energy rating ensures robustness against inductive switching transients in unclamped loads. |
Pinout & Package
PHP152NQ03LTA is housed in TO-220AB plastic single-ended package (SOT78), featuring a metal mounting base electrically connected to the drain terminal for mechanical attachment and thermal dissipation. Pin 2 is internally connected to the mounting base and not accessible externally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate (G) | Control input; logic-level compatible (VGS(th) = 1.5 V typ.), requires <36 nC charge for full enhancement. |
| 2 | Drain (D) / Mounting Base | High-current power output node; electrically tied to metal tab - must be isolated from PCB ground unless drain-referenced topology. |
| 3 | Source (S) | Power return path; referenced to gate drive; forms common node for current sensing and feedback in buck/boost topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate threshold | VGS(th) = 1–2 V enables direct interface with 3.3 V/5 V MCUs and PWM controllers without gate drivers. |
| Ultra-low RDS(on) | 3.4 mΩ @ 10 V ensures minimal I²R loss in high-current paths - critical for >95% efficiency in 12 V input converters. |
| TrenchMOS™ architecture | Optimized cell density and trench geometry deliver lower gate charge and higher figure-of-merit (RDS(on) × Qg) than planar MOSFETs. |
| Avalanche-rated | 560 mJ unclamped inductive energy handling supports reliable operation in flyback, forward, and LLC resonant converters. |
| Low thermal resistance | Rth(j-mb) = 1 K/W allows >100 W power dissipation with modest heatsinking - simplifies thermal design in space-constrained PSUs. |
Applications
| DC-DC Buck Converter | Switched-Mode Power Supply (SMPS) |
|---|---|

Use Scenario: High-current step-down conversion from 12 V to 3.3 V/5 V in server VRMs or telecom power modules. IC Role / Device Role / Timing Role: Synchronous rectifier switch in low-side position, driven by dedicated gate controller or MCU PWM. Use Value: 3.4 mΩ RDS(on) minimizes conduction loss at 50–75 A loads, while 36 nC Qg enables efficient 300–500 kHz operation. |
Use Scenario: Primary-side switching in 200–500 W AC-DC adapters or industrial open-frame PSUs. IC Role / Device Role / Timing Role: High-side or low-side power switch in forward, flyback, or active-clamp topologies. Use Value: 560 mJ avalanche energy rating withstands transformer leakage inductance spikes; 25 V VDS suits secondary-side synchronous rectification. |
| Motor Drive Half-Bridge | Hot-Swap / Load Switch |
|
Use Scenario: Low-voltage BLDC or stepper motor phase switching in battery-powered tools or robotics. IC Role / Device Role / Timing Role: N-channel high-side or low-side switch in H-bridge configuration, controlled via gate driver IC. Use Value: Logic-level VGS(th) allows compact gate drive design; 75 A DC rating supports peak motor currents up to 100 A with proper heatsinking. |
Use Scenario: Inrush-limited power sequencing in FPGA, ASIC, or GPU power domains. IC Role / Device Role / Timing Role: Single-pole power switch with external RC gate control for soft-start and overcurrent protection. Use Value: Low RDS(on) limits voltage drop during steady-state operation; integrated body diode enables reverse-current blocking when used with external Schottky. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF1404PBF | VDS = 40 V, RDS(on) = 4.8 mΩ @ 10 V, Qg = 131 nC - higher voltage rating but significantly higher gate charge and on-resistance. | Better suited for 24–36 V input systems; less efficient at high-frequency, high-current operation due to higher Qg. | Select IRF1404PBF only if 40 V VDS margin is required; PHP152NQ03LTA offers superior efficiency in ≤25 V rails. |
| STP75NF25 | VDS = 25 V, RDS(on) = 4.5 mΩ @ 10 V, Qg = 100 nC - same voltage rating but 2.8× higher gate charge than PHP152NQ03LTA. | Compatible in DC-DC and SMPS roles but demands stronger gate drivers and exhibits slower switching transitions. | Prefer PHP152NQ03LTA for high-frequency designs (>200 kHz); STP75NF25 may be acceptable where gate drive strength is abundant and frequency is low. |
Compared with IRF1404PBF and STP75NF25, PHP152NQ03LTA delivers the lowest RDS(on) × Qg figure-of-merit among these 25 V logic-level MOSFETs, enabling higher efficiency and smaller gate drivers in compact, high-current power stages.

FAQ
What is the maximum continuous drain current rating for PHP152NQ03LTA?
The PHP152NQ03LTA is rated for 75 A DC continuous drain current at Tmb = 25 °C with VGS = 10 V. Derating applies above 25 °C mounting base temperature per Figure 2 in the datasheet; at Tmb = 100 °C, it maintains 75 A capability due to its low RDS(on) and thermal design. Actual usable current depends on PCB layout, heatsinking, and ambient conditions.
Does PHP152NQ03LTA support logic-level gate drive?
Yes, PHP152NQ03LTA features a logic-level gate threshold voltage (VGS(th)) of 1–2 V typical at Tj = 25 °C, allowing full enhancement with standard 3.3 V or 5 V microcontroller outputs. This eliminates the need for external level shifters or high-side gate drivers in many low-voltage power stage designs.
What is the thermal resistance from junction to mounting base for PHP152NQ03LTA?
The PHP152NQ03LTA has a specified Rth(j-mb) of 1 K/W, measured from silicon junction to the metal mounting base. This low value enables effective heat transfer to an external heatsink, supporting up to 150 W total power dissipation at Tmb = 25 °C - critical for thermally constrained power supply designs.
Is PHP152NQ03LTA avalanche-rated, and what is its energy rating?
Yes, PHP152NQ03LTA is fully avalanche-rated with a non-repetitive drain-source avalanche energy (EDS(AL)S) of 560 mJ under specified test conditions (unclamped inductive load, ID = 75 A, VDD ≤ 25 V). This rating ensures robustness against transient voltage spikes in inductive switching applications like flyback and forward converters.
What package type does PHP152NQ03LTA use, and how is pin 2 configured?
PHP152NQ03LTA uses the TO-220AB plastic single-ended package (SOT78), with three leads and a metal mounting base. Pin 2 is internally connected to the mounting base (drain) and is not accessible as an external lead - only pins 1 (gate) and 3 (source) are electrically functional terminals; the base serves as both thermal path and drain connection.
