NXP Semiconductors PHX20N06T,127

Overview

PHX20N06T from NXP Semiconductors (formerly Philips Semiconductors) is an N-channel TrenchMOS™ standard-level power MOSFET in a fully isolated TO-220F (SOT186A) package, rated for 55 V V_DS, 12.9 A continuous drain current at T_H = 25 °C, and 75 mΩ maximum R_DS(on) at V_GS = 10 V and T_j = 25 °C. It serves as a high-efficiency, thermally robust switching element in DC motor control, synchronous rectification, and DC-to-DC converters.

For engineers reviewing the PHX20N06T datasheet, PHX20N06T pinout, PHX20N06T application, or PHX20N06T equivalent, key selection considerations include its isolated mounting base (2500 V_RMS isolation), low gate charge (9.8 nC typical), avalanche ruggedness (30.3 mJ), and thermal resistance of 5.4 K/W from junction to heatsink - critical for high-reliability power switching designs with external heatsinking.

Technical Context

This device employs TrenchMOS™ technology to achieve enhanced conduction efficiency and fast switching performance. Its standard-level gate drive (V_GS(th) = 2–4 V at 25 °C) ensures compatibility with 5 V and 10 V logic-level controllers without requiring level-shifting circuitry.

The fully isolated plastic package (TO-220F/SOT186A) integrates a mounting base electrically separated from all three terminals, enabling direct heatsink attachment while maintaining 2500 V_RMS isolation between drain and heatsink - essential for safety-critical and floating-ground topologies.

Key Specifications

Pinout & Package

PHX20N06T uses the SOT186A (TO-220F) package: a plastic single-ended 3-lead full-pack with electrically isolated mounting base. The heatsink-mounting surface is internally insulated from drain, source, and gate terminals.

FAQ

What is the maximum continuous drain current rating for PHX20N06T?

The PHX20N06T supports 12.9 A continuous drain current at heatsink temperature (T_H) = 25 °C and V_GS = 10 V. This rating drops to 8.1 A at T_H = 100 °C due to thermal derating. The device must be mounted to an external heatsink - its R_th(j-h) is 5.4 K/W - to sustain these currents reliably. PHX20N06T is not rated for 12.9 A without active heatsinking.

Does PHX20N06T require a gate driver IC for microcontroller interfacing?

PHX20N06T has a standard-level gate threshold (V_GS(th) = 2–4 V at 25 °C), making it compatible with direct drive from 5 V microcontrollers. However, its 9.8 nC total gate charge means that driving it directly from low-current GPIO pins may cause slow switching and increased power loss. For robust 100+ kHz operation, a dedicated gate driver (e.g., TC4420) is recommended. PHX20N06T does not require level-shifting but benefits from buffered gate drive.

What is the isolation voltage rating of PHX20N06T and how is it verified?

PHX20N06T provides 2500 V_RMS isolation between all three terminals (gate, source, drain) and the mounting base, tested per 50–60 Hz sinusoidal waveform at ≤65 % relative humidity. This rating is specified in Table 6 of the official product data sheet (Rev. 01, 2004) and enables safe direct mounting to grounded heatsinks without insulating hardware. PHX20N06T's isolation is intrinsic to its TO-220F (SOT186A) package construction.

Can PHX20N06T be used in avalanche mode, and what is its rated energy?

Yes, PHX20N06T is rated for non-repetitive unclamped inductive avalanche with E_DS(AL)S = 30.3 mJ under defined conditions (I_D = 11 A, V_DD ≤15 V, t_p = 0.06 ms, R_GS = 50 Ω, V_GS = 10 V, starting T_j = 25 °C). This capability supports reliable operation in flyback, boost, and other inductive-switching topologies without requiring external avalanche-rated components. PHX20N06T's datasheet explicitly characterizes this parameter.

What is the typical reverse recovery charge (Q_r) of the body diode in PHX20N06T?

The PHX20N06T's integrated body diode has a typical recovered charge (Q_r) of 120 nC, measured at I_S = 20 A, dI_S/dt = −100 A/µs, V_GS = −10 V, and V_DS = 30 V. This value - along with 32 ns typical reverse recovery time (t_rr) - makes PHX20N06T suitable for synchronous rectification in medium-frequency DC-DC converters where low diode recovery loss is critical. PHX20N06T's Q_r is documented in Table 5 of its product data sheet.
