Product details

Overview

PHP176NQ04T,127 from NXP Semiconductors is a standard-level N-channel TrenchMOS power MOSFET in TO-220AB (SOT78) package, rated for 40 V V_DS, 75 A continuous drain current at T_mb = 25 °C, and 250 W total power dissipation. It delivers 3.8 mΩ R_DS(on) at V_GS = 10 V and T_j = 25 °C, and is qualified for industrial, computing, and UPS applications requiring robust conduction efficiency and standard gate drive compatibility.

For engineers reviewing the PHP176NQ04T,127 datasheet, PHP176NQ04T,127 pinout, PHP176NQ04T,127 application, or PHP176NQ04T,127 equivalent, key selection criteria include its low on-resistance, avalanche energy rating of 560 mJ, thermal resistance of 0.6 K/W (junction-to-mounting-base), gate charge profile (Q_G(tot) = 68.9 nC), and suitability for high-current DC-DC converters and motor control circuits with heatsink mounting.

Technical Context

This MOSFET uses TrenchMOS technology to achieve low R_DS(on) while maintaining stable threshold voltage (V_GS(th) = 2–4 V at T_j = 25 °C) and controlled dynamic characteristics including Q_GD = 22.2 nC and C_iss = 3620 pF. Its gate is compatible with standard 10 V logic-level drivers, eliminating need for level-shifting circuitry.

The device features an integrated source-drain diode with V_SD = 0.85–1.2 V at I_S = 25 A and fast reverse recovery (t_rr = 68 ns, Q_r = 62 nC), enabling use in synchronous rectification and freewheeling paths without external diodes in many topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum drain-source blocking voltage; defines upper limit for switch node voltage in buck, boost, and half-bridge topologies.
R_DS(on)	3.8 mΩ (typ) at V_GS = 10 V, I_D = 25 A, T_j = 25 °C - Enables <1 W conduction loss at 50 A, critical for high-efficiency power stages.
I_D (continuous)	75 A at T_mb = 25 °C - Supports high-current loads such as solenoid drivers and DC motor H-bridges with appropriate heatsinking.
E_DS(AL)S	560 mJ - Non-repetitive unclamped avalanche energy; allows safe operation during inductive turn-off transients without snubbers.
R_th(j-mb)	0.6 K/W - Junction-to-mounting-base thermal resistance enables direct heatsink coupling for sustained 250 W dissipation.
Q_G(tot)	68.9 nC - Total gate charge determines driver strength requirement; compatible with common 1–2 A peak gate drivers.
V_GS(th)	2–4 V at T_j = 25 °C - Ensures reliable turn-on with standard 5 V or 10 V logic, with margin against false triggering at elevated temperature.

Pinout & Package

Package: TO-220AB (SOT78), plastic single-ended package with heatsink-mounted mounting base electrically connected to drain. Dimensions per Figure 14: 15.2–16.0 mm length, 9.7–10.3 mm width, 4.1–4.7 mm height, 3.30–3.8 mm lead pitch.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control terminal; requires ≤20 V gate-source voltage; driven by standard logic-level PWM controllers.
2 (D)	Drain	Main high-side switching node; electrically tied to mounting base for low-inductance heatsink connection.
3 (S)	Source	Power return path and reference for gate drive; used as common node in low-side switch configurations.
Mounting base (mb)	Drain tie	Electrically connected to drain pin; must be isolated from chassis unless drain is referenced to system ground.

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF1404PBF	Higher R_DS(on) (4.7 mΩ), same V_DS (40 V), higher Q_G (131 nC), TO-220 package	Requires stronger gate driver; less efficient at high current due to +24 % conduction loss	Acceptable where gate drive strength is available and marginal efficiency loss is acceptable.
STP75NF75	Higher V_DS (75 V), similar R_DS(on) (7.5 mΩ), lower I_D (75 A), TO-220 package	Over-specified voltage rating increases cost and capacitance; higher R_DS(on) raises conduction loss	Only suitable if 75 V rating is required for future-proofing or transient margin beyond 40 V systems.

FAQ

What is the maximum continuous drain current rating for PHP176NQ04T,127?

The PHP176NQ04T,127 is rated for 75 A continuous drain current at mounting base temperature (T_mb) = 25 °C with adequate heatsinking. At T_mb = 100 °C, the derated current remains 75 A per Figure 1 in the datasheet, confirming robust thermal design for high-power industrial applications.

Does PHP176NQ04T,127 require a gate driver with negative voltage capability?

No - PHP176NQ04T,127 has a gate-source voltage rating of ±20 V and operates fully enhanced with 10 V gate drive. Its V_GS(th) range (2–4 V at 25 °C) ensures reliable turn-on using standard 5 V or 10 V logic-level drivers without negative gate biasing.

Is PHP176NQ04T,127 suitable for synchronous rectification in DC-DC converters?

Yes - PHP176NQ04T,127 supports synchronous rectification via its low R_DS(on) (3.8 mΩ) and fast source-drain diode (t_rr = 68 ns, Q_r = 62 nC). Its integrated body diode enables efficient freewheeling in buck converters when used as the low-side switch.

What is the thermal resistance from junction to mounting base for PHP176NQ04T,127?

The PHP176NQ04T,127 has a maximum thermal resistance of R_th(j-mb) = 0.6 K/W from junction to mounting base, as specified in Table 5. This value enables direct heatsink mounting and supports 250 W continuous power dissipation under proper thermal interface conditions.

Can PHP176NQ04T,127 replace older N-channel MOSFETs like IRF1404 in existing designs?

PHP176NQ04T,127 is a functional alternative to IRF1404 in TO-220-based designs, offering lower R_DS(on) (3.8 mΩ vs. 4.7 mΩ) and better thermal resistance (0.6 K/W vs. ~1.0 K/W). Pinout is identical, but layout review is recommended to confirm gate drive stability given reduced Q_G (68.9 nC vs. 131 nC).
