Product details

Overview

PHP36N03LT from Nexperia is a logic-level N-channel TrenchMOS power FET in TO-220AB (SOT78) package, designed for high-efficiency switching in DC-DC converters and SMPS. It delivers 43.4 A continuous drain current at V_GS = 10 V and T_mb = 25 °C, with R_DS(on) = 14 mΩ (typ.) at 25 °C, 25 A, and supports 30 V V_DS rating.

For engineers reviewing the PHP36N03LT datasheet, PHP36N03LT pinout, PHP36N03LT application, or PHP36N03LT equivalent, key selection criteria include gate-threshold voltage (V_GS(th) = 1.0–1.5 V typ. at 25 °C), low Q_GD (2.9 nC), thermal resistance R_th(j-mb) = 2.6 K/W, and suitability for logic-level drive in high-current, medium-voltage power stages.

Technical Context

This device implements trench-gate MOSFET architecture optimized for low gate charge (Q_G(tot) = 18.5 nC) and fast switching (t_d(on) = 6 ns, t_f = 19 ns), enabling high-frequency operation in synchronous buck converters. Its R_DS(on) remains stable across temperature due to TrenchMOS process control, with 32.4 mΩ (max) at 175 °C and V_GS = 4.5 V.

The integrated source-drain diode exhibits V_SD = 0.97–1.2 V at I_S = 25 A and 25 °C, supporting freewheeling in non-synchronous topologies. Mounting base (pin 2) is electrically connected to drain, requiring isolation from heatsink unless referenced to drain potential.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum drain-source blocking voltage; defines use in ≤24 V input systems with margin.
I_D (continuous)	43.4 A at T_mb = 25 °C, V_GS = 10 V - Supports high-current output stages without forced air cooling.
R_DS(on)	14 mΩ (typ.) at V_GS = 10 V, I_D = 25 A, T_j = 25 °C - Enables <1 W conduction loss at 25 A, critical for thermal management.
Q_GD	2.9 nC - Low gate-drain charge minimizes Miller-induced switching delay and improves hard-switching efficiency.
R_th(j-mb)	2.6 K/W - Junction-to-mounting-base thermal resistance enables direct heatsink coupling for high-power dissipation (57.6 W).
V_GS(th)	1.0–1.5 V (typ.) at 25 °C - Ensures full enhancement with 3.3 V or 5 V logic-level gate drivers without level-shifting.
C_iss	690 pF - Input capacitance determines gate drive strength requirement; compatible with standard MOSFET drivers.

Pinout & Package

Package: TO-220AB (SOT78), plastic single-ended package with heatsink-mounted mounting base (pin 2), 3-lead configuration. Mounting base is electrically connected to drain.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control terminal; accepts logic-level voltages (≥3.5 V) for full enhancement; low Q_G reduces driver loading.
2 (D / mb)	Drain / Mounting Base	Main high-side current path; mounting base is internally tied to drain - requires electrical isolation from heatsink unless drain-referenced.
3 (S)	Source	Power return node; referenced to system ground in low-side switch configurations; carries full load current.

Key Features

Feature	Design Value
Logic-level gate drive compatibility	Operates fully enhanced at V_GS ≥ 4.5 V, enabling direct interface with 3.3 V/5 V microcontrollers and PWM controllers.
Low gate charge (Q_G(tot))	18.5 nC total gate charge reduces switching losses and allows higher frequency operation without excessive driver power.
TrenchMOS technology	Delivers lower R_DS(on) per die area versus planar MOSFETs, improving power density and thermal performance in TO-220AB.
High peak current capability	IDM = 173.6 A (pulsed, tp ≤ 10 µs) supports surge handling in motor drives and inrush-limited power supplies.
Robust thermal design	R_th(j-mb) = 2.6 K/W enables >50 W continuous dissipation with properly sized heatsink, reducing need for derating.

Applications

DC-DC Converters

Switched-Mode Power Supplies

Use Scenario: Synchronous rectification in 12 V input, 3.3 V/5 V output buck converters for server VRMs and telecom modules.

IC Role / Device Role: Low-side power switch handling continuous 30+ A output current with minimal conduction loss.

Use Value: 14 mΩ R_DS(on) limits I²R loss to <1.1 W at 25 A, directly improving conversion efficiency and easing thermal design.

Use Scenario: Primary-side switching in offline AC-DC adapters and industrial power supplies with universal input (85–265 VAC).

IC Role / Device Role: High-current, medium-voltage switch in flyback or forward converter primary circuits operating below 30 V clamp conditions.

Use Value: 30 V V_DS rating with 173.6 A pulsed current supports robust operation under transient overloads and reflected voltage spikes.

Motor Drive Half-Bridges

Hot-Swap Controllers

Use Scenario: Low-side switch in brushed DC motor H-bridge drivers for industrial automation and robotics.

IC Role / Device Role: Bidirectional current-handling switch with integrated body diode for freewheeling during PWM off-time.

Use Value: V_SD = 0.97 V at 25 A ensures low forward drop during freewheeling, reducing heat generation compared to external Schottky solutions.

Use Scenario: Inrush current limiting and fault protection in 12 V/24 V backplane power distribution units.

IC Role / Device Role: Load switch controlling hot-plug insertion of FRUs (Field Replaceable Units) into live backplanes.

Use Value: Logic-level gate threshold and low R_DS(on) allow precise, low-loss current limiting using simple gate resistor + Zener clamping networks.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level power FET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF3205PBF	R_DS(on) = 8.0 mΩ (typ.) at V_GS = 10 V but V_GS(th) = 2.0–4.0 V - requires ≥5 V drive for reliable turn-on.	Higher gate threshold increases risk of partial turn-on in 3.3 V systems; better suited for 5 V controller designs.	Select when lower R_DS(on) is prioritized and gate drive is guaranteed ≥5 V; avoid in 3.3 V logic-driven systems.
STP36NF03L	R_DS(on) = 13 mΩ (typ.) at V_GS = 10 V; V_GS(th) = 1.0–2.5 V; Q_GD = 3.8 nC - higher Miller charge than PHP36N03LT.	Increased Q_GD raises switching losses in high-frequency (>300 kHz) SMPS; otherwise functionally interchangeable.	Prefer for cost-sensitive designs where switching frequency ≤200 kHz; PHP36N03LT offers superior high-frequency efficiency.

Compared with IRF3205PBF and STP36NF03L, PHP36N03LT provides optimal balance of logic-level compatibility (V_GS(th) ≤ 1.5 V), low Q_GD, and proven thermal robustness in TO-220AB - making it preferred for compact, high-efficiency 3.3 V/5 V-controlled power stages.

FAQ

Is PHP36N03LT suitable for 3.3 V microcontroller gate drive?

Yes. With V_GS(th) = 1.0–1.5 V (typ.) at 25 °C and R_DS(on) = 22–40 mΩ at V_GS = 3.5 V and I_D = 5.2 A, PHP36N03LT achieves usable on-resistance under 3.3 V drive. Full enhancement occurs at ≥4.5 V, so 3.3 V operation is viable for moderate-current applications with acceptable R_DS(on) increase.

What is the maximum safe operating temperature for continuous operation?

The junction temperature must not exceed 175 °C. At T_mb = 100 °C, the rated continuous drain current drops to 30.7 A (V_GS = 10 V). Using R_th(j-mb) = 2.6 K/W, a 50 °C temperature rise above mounting base corresponds to ~19.2 W power dissipation - confirming thermal derating is required above T_mb ≈ 75 °C for full 43.4 A operation.

Can the mounting base be electrically connected to the PCB ground plane?

No - pin 2 (mounting base) is internally connected to the drain. Connecting it to PCB ground creates a short circuit unless the drain node is ground-referenced. For low-side switch configurations, isolate the mounting base with mica or ceramic washer; for high-side use, mount directly to a drain-potential heatsink.

Does PHP36N03LT have avalanche ruggedness rating?

No avalanche energy rating (E_AS) is specified in the datasheet. The device is characterized per IEC 60134 absolute maximum ratings only. It is not rated for repetitive unclamped inductive switching; external snubbers or clamping circuits are required in inductive load applications to prevent drain voltage overshoot beyond 30 V.
