Product details

Overview

PHK13N03LT from Nexperia is a logic-level N-channel TrenchMOS FET in SO8 (SOT96-1) package, rated for 30 V V_DS, 13.8 A continuous drain current at T_sp = 25 °C, and 17–20 mΩ R_DS(on) at V_GS = 10 V / I_D = 8 A / T_j = 25 °C. It serves as a high-efficiency synchronous rectifier or load switch in DC-DC converters and lithium-ion battery protection circuits.

For engineers reviewing the PHK13N03LT datasheet, PHK13N03LT pinout, PHK13N03LT application, or PHK13N03LT equivalent, this device is selected for low gate charge (10.7 nC), fast switching (t_d(off) = 23 ns), and logic-compatible 4.5 V gate drive-critical for compact portable power designs requiring minimal drive complexity and thermal margin.

Technical Context

This MOSFET uses TrenchMOS technology to achieve low R_DS(on) and reduced gate charge versus planar alternatives. Its 30 V V_DS rating and 55 A peak drain current support robust operation in 12–24 V input DC-DC stages with transient overloads.

The device features an integrated body diode with 0.86–1.1 V forward voltage at 7 A and 25 ns reverse recovery time, enabling efficient freewheeling in synchronous buck topologies without external Schottky supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum drain-source blocking voltage; supports 24 V nominal bus systems with 25 % safety margin.
I_D (continuous)	13.8 A at T_sp = 25 °C - Sustains full-load current in notebook CPU VRMs or USB PD sink switches without forced airflow.
R_DS(on)	17–20 mΩ at V_GS = 10 V / I_D = 8 A / T_j = 25 °C - Enables ≤1.3 W conduction loss at 8 A, reducing thermal design burden.
Q_G(tot)	10.7 nC - Low gate charge allows direct drive from 3.3 V/5 V microcontrollers without buffer stages.
t_d(off)	23 ns - Supports >1 MHz switching in high-frequency DC-DC converters while maintaining dead-time control integrity.
V_GS(th)	1.0–2.2 V - Guaranteed turn-on with 2.5 V logic; compatible with Li-ion battery voltage range (2.5–4.2 V).
R_th(j-sp)	20 K/W - Junction-to-solder-point thermal resistance enables 3.1 W dissipation at 62.5 °C ΔT above PCB solder point.

Pinout & Package

PHK13N03LT is housed in an SO8 plastic small outline package (SOT96-1), 3.9 mm body width, with exposed drain pad for enhanced thermal performance. The package supports standard reflow profiles and is RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Source (S)	Common source connection; internally bonded to all three pins for low-inductance return path in high-di/dt applications.
4	Gate (G)	Control terminal; accepts logic-level drive (≥2.5 V); gate capacitance optimized for fast edge rates with minimal ringing.
5, 6, 7, 8	Drain (D)	High-current output node; pins 5–8 are internally paralleled and connected to exposed copper pad for thermal and current sharing.

Key Features

Feature	Design Value
Logic-level gate threshold	V_GS(th) = 1.0–2.2 V ensures reliable turn-on from 3.3 V microcontrollers and battery-powered gate drivers.
Low R_DS(on) at 4.5 V	21–26 mΩ at V_GS = 4.5 V / I_D = 7 A enables use in 5 V-input buck converters without gate boosting.
Fast switching with low Q_GD	Q_GD = 3.9 nC minimizes Miller plateau duration, improving efficiency and EMI in hard-switched topologies.
Integrated body diode	V_SD = 0.86–1.1 V at 7 A / T_j = 25 °C provides low-loss freewheeling in synchronous rectification.

Applications

DC-DC Converters

Lithium-ion Battery Protection

Use Scenario: Synchronous rectifier in 12 V input → 1.2 V/20 A CPU VRM for notebook platforms.

IC Role / Device Role / Timing Role: Low-side switch operating at 500 kHz–1 MHz with precise dead-time control.

Use Value: 17 mΩ R_DS(on) reduces conduction loss by 40 % vs. comparable 25 mΩ devices, lowering junction temperature rise by ~12 °C at full load.

Use Scenario: Charge/discharge path switch in single-cell Li-ion pack with overcurrent cutoff.

IC Role / Device Role / Timing Role: Bidirectional load switch controlled by battery management IC (e.g., BQ297xx).

Use Value: 2.2 V max V_GS(th) guarantees turn-off during deep discharge (≤2.5 V cell voltage), preventing uncontrolled discharge.

Notebook Computers

Portable Equipment

Use Scenario: Main system power switch enabling instant-on functionality and deep sleep state isolation.

IC Role / Device Role / Timing Role: High-side or low-side power OR-ing switch controlled by EC firmware.

Use Value: 13.8 A continuous rating supports 65 W adapter input; low Q_G enables <10 µs turn-on for rapid wake-up response.

Use Scenario: Load switch for USB-C port power delivery negotiation and VBUS enable.

IC Role / Device Role / Timing Role: Controlled power gate between USB PD controller and downstream power rail.

Use Value: 30 V V_DS withstands 20 V PPS bursts; 55 A peak current handles 5 A @ 20 V short-circuit events per USB PD 3.1 spec.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRLML6344TRPBF	R_DS(on) = 22 mΩ @ 4.5 V; SO-8 package; higher Q_G = 12.5 nC; lower I_D = 4.3 A	Lower current capability limits use to sub-10 W loads; unsuitable for 13.8 A DC-DC outputs.	Select only for space-constrained <5 W applications where gate drive margin exceeds 10.7 nC requirement.
DMN3025LFG-7	R_DS(on) = 25 mΩ @ 4.5 V; same SO-8 footprint; higher V_GS(th) = 1.2–2.4 V; Q_G = 11.5 nC	Slightly higher threshold increases risk of partial turn-on near battery end-of-discharge (2.8 V).	Acceptable for industrial portable gear with regulated 3.3 V gate supply; avoid in direct Li-ion gate drive.

Compared with IRLML6344TRPBF and DMN3025LFG-7, PHK13N03LT delivers superior current handling (13.8 A vs. ≤4.3 A), tighter V_GS(th) distribution (0.5–2.2 V), and lower R_DS(on) at 4.5 V-making it uniquely suited for high-power portable DC-DC and battery-switching roles where thermal headroom and gate drive simplicity are critical.

FAQ

Is PHK13N03LT suitable for 3.3 V gate drive?

Yes-its V_GS(th) ranges from 0.5 V to 2.2 V, and R_DS(on) is specified down to 21 mΩ at V_GS = 4.5 V. At 3.3 V, typical R_DS(on) is ~35 mΩ (per Figure 9 extrapolation), supporting moderate-current applications like 2–3 A load switches where conduction loss remains acceptable.

What is the maximum safe operating temperature for continuous operation?

The absolute maximum junction temperature is 150 °C, but continuous operation should be limited to T_j ≤ 125 °C for reliability. With R_th(j-sp) = 20 K/W and a 60 °C PCB solder point, maximum allowable power dissipation is 3.25 W-corresponding to ~5.7 A at 17 mΩ R_DS(on).

Does PHK13N03LT have avalanche ruggedness rating?

No avalanche rating is specified in the datasheet. The device is not characterized for repetitive or single-pulse avalanche energy (E_AS). Designers must ensure voltage transients remain within the 30 V V_DS limit using snubbers or clamping circuits in inductive switching applications.

Can PHK13N03LT replace older PHK13N03L in existing designs?

Yes-PHK13N03LT is the direct successor to PHK13N03L (Rev. 01), with identical pinout, electrical specs, and package. The Rev. 02 datasheet reflects updated formatting and legal text; no parametric or reliability changes were introduced.
