Product details

Overview

PHP191NQ06LT from NXP Semiconductors is a logic-level N-channel TrenchMOS power MOSFET in TO-220AB (SOT78) package, rated for 55 V V_DS, 75 A continuous drain current at T_mb = 25 °C, and 3.1 mΩ R_DS(on) at V_GS = 10 V and T_j = 25 °C. It serves as a high-current switching element in DC-DC converters, motor drives, and UPS systems where low conduction loss and direct 3.3/5 V microcontroller gate drive are required.

For engineers reviewing the PHP191NQ06LT datasheet, PHP191NQ06LT pinout, PHP191NQ06LT application, or PHP191NQ06LT equivalent, key selection criteria include its 3.1 mΩ on-resistance at 10 V gate drive, 240 A peak pulsed current capability, junction-to-mounting-base thermal resistance of 0.5 K/W, and suitability for industrial-grade power switching with logic-level gate compatibility.

Technical Context

This device uses NXP's TrenchMOS technology to achieve low R_DS(on) while maintaining robust avalanche ruggedness (560 mJ unclamped). Its gate threshold voltage ranges from 0.5 V (T_j = 175 °C) to 2.2 V (T_j = −55 °C), enabling reliable turn-on across temperature extremes with standard logic-level sources.

The integrated source-drain diode exhibits 0.79 V forward voltage at 25 A and 25 °C, with 78 ns reverse recovery time and 171 nC recovered charge-critical for synchronous rectification and hard-switched topologies. Thermal design leverages the mounting base (electrically connected to drain) for low-impedance heat transfer to external heatsinks.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	55 V maximum drain-source voltage - defines safe blocking capability in 48 V bus and 54 V surge-tolerant systems
R_DS(on)	3.1 mΩ typical at V_GS = 10 V, I_D = 25 A, T_j = 25 °C - enables <1 W conduction loss at 50 A, reducing heatsink requirements
I_D (continuous)	75 A at T_mb = 25 °C - supports high-power industrial loads without derating in well-cooled designs
Q_GD	37.6 nC typical - determines Miller-induced switching delay and gate driver current demand during transition
R_th(j-mb)	0.5 K/W - allows direct thermal path from silicon die to heatsink, enabling >200 W dissipation with modest ΔT
V_GS(th)	1.0–2.0 V typical at 25 °C - ensures full enhancement with 3.3 V or 5 V logic outputs without level-shifting
E_AS	560 mJ non-repetitive avalanche energy - provides single-pulse fault tolerance in inductive load switching

Pinout & Package

Package: TO-220AB (SOT78), plastic single-ended package with electrically active mounting base connected to drain terminal. Designed for heatsink mounting with one mounting hole and vertical PCB orientation.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control input; requires ≤15 V drive; 2 nA leakage at 25 °C enables low-power bias networks
2 (D)	Drain	Main power output; electrically tied to mounting base - must be isolated from heatsink unless system ground reference permits
3 (S)	Source	Power return path; referenced to gate drive common; supports 75 A continuous and 240 A pulsed current

Key Features

Feature	Design Value
Logic-level gate drive	Turns fully on with 3.3 V or 5 V microcontroller outputs - eliminates need for gate driver ICs in many embedded power stages
TrenchMOS architecture	Delivers 3.1 mΩ R_DS(on) in TO-220AB - achieves performance comparable to larger packages without footprint penalty
Low Q_G/Q_GD ratio	95.6 nC total gate charge with 37.6 nC Miller charge - improves switching efficiency and reduces EMI in high-frequency SMPS
Robust body diode	78 ns t_rr, 171 nC Q_r - enables use in synchronous buck and freewheeling paths without external Schottky replacement
Avalanche-rated	560 mJ unclamped E_AS - withstands inductive kickback in motor control and relay driving without snubber circuits

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
STP75NF75	75 V V_DS, 75 A I_D, 7.5 mΩ R_DS(on) @ 10 V - higher on-resistance, TO-220FP package with insulated tab	Requires heatsink isolation; less efficient at high current due to 2.4× higher R_DS(on)	Preferred when higher voltage margin (75 V) is mandatory and thermal budget allows extra loss
IRF1404ZLPbF	40 V V_DS, 200 A I_D, 4.7 mΩ R_DS(on) @ 10 V - lower voltage rating, higher current, D2PAK package	Not suitable for 48 V systems; superior current handling but requires surface-mount assembly and larger PCB area	Chosen for high-current 12/24 V systems where board space permits SMD layout and voltage stress stays below 32 V

Compared with STP75NF75 and IRF1404ZLPbF, PHP191NQ06LT uniquely balances 55 V rating, sub-4 mΩ on-resistance, TO-220AB through-hole mountability, and true logic-level gate drive - making it optimal for cost-sensitive, thermally constrained 48 V industrial power stages requiring plug-in replaceability.

FAQ

Is PHP191NQ06LT suitable for 48 V battery-powered systems?

Yes - its 55 V V_DS rating provides 7 V headroom above nominal 48 V bus, accommodating load-dump transients up to ISO 16750-2 Level IV (58 V/100 ms). The 3.1 mΩ R_DS(on) minimizes voltage drop and self-heating during sustained 50–75 A operation, supporting high-efficiency battery discharge cycles.

What is the maximum gate-source voltage I can apply?

The absolute maximum V_GS is ±15 V per datasheet limiting values. Operation beyond ±12 V risks permanent gate oxide damage. For reliable logic-level drive, use 0 V to +10 V; gate drive circuits must clamp negative excursions below −5 V during switching transitions to prevent latch-up or degradation.

Can PHP191NQ06LT be used in parallel configurations?

Yes - its positive temperature coefficient of R_DS(on) (see Figure 9) ensures inherent current sharing stability. Parallel operation requires matched gate drive impedance, symmetrical PCB layout, and shared heatsink mounting to maintain thermal uniformity. Derate total current by 15% versus sum of individual ratings for reliability.

Does the mounting base require electrical isolation from the heatsink?

Yes - the mounting base is internally connected to the drain terminal (Pin 2). If the heatsink is grounded or at a different potential than the drain node, an electrically insulating pad (e.g., mica or ceramic) plus shoulder washer must be used. Failure to isolate may cause short-circuit failure or system ground loop issues.
