Nexperia USA Inc. PHPT60610NYX

Overview

PHPT60610NYX from Nexperia is a 60 V, 10 A NPN high-power bipolar transistor in LFPAK56 (SOT669) package, designed for high-current switching and linear-mode power control. It delivers R_CE(sat) = 25–36 mΩ at I_C = 10 A / I_B = 1 A, operates up to T_j = 175 °C, and is AEC-Q101 qualified for automotive load switching and motor drive applications.

For engineers reviewing the PHPT60610NYX datasheet, PHPT60610NYX pinout, PHPT60610NYX application, or PHPT60610NYX equivalent, this device supports high-efficiency thermal management in space-constrained PCBs, replaces DPAK transistors with reduced footprint, and serves as a robust alternative to discrete power switches in 12 V/24 V automotive subsystems.

Technical Context

This NPN bipolar transistor uses silicon planar epitaxial technology optimized for high-current saturation and low on-state resistance. Its LFPAK56 package integrates an exposed mounting base for direct thermal coupling to PCB copper, enabling 25 W total power dissipation at T_amb ≤ 25 °C with ceramic substrate mounting.

The device features fast switching performance (t_on = 200 ns, t_off = 505 ns) under pulsed conditions (δ ≤ 0.02), with h_FE = 50–100 at I_C = 10 A and V_CE = 2 V, supporting stable current gain across −55 °C to +175 °C operating range.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous collector current for PHPT60610NYX?

The maximum continuous collector current (I_C) is 10 A at T_amb ≤ 25 °C with proper PCB thermal management. Derating applies above 25 °C ambient: for example, at 100 °C ambient, maximum I_C drops to approximately 5.5 A based on the 25 W P_tot limit and R_th(j-a) = 30 K/W on ceramic substrate.

How does the LFPAK56 package improve thermal performance over standard DPAK?

The LFPAK56 package reduces thermal resistance via an exposed mounting base directly soldered to large PCB copper areas, achieving R_th(j-mb) = 6 K/W versus ~15 K/W for typical DPAK. This allows 25 W power dissipation-nearly double that of DPAK-while occupying 40% less board area and eliminating mechanical heatsinks.

Is PHPT60610NYX suitable for linear-mode operation in voltage regulators?

Yes-its specified R_CE(sat), h_FE stability from −55 °C to 175 °C, and 25 W P_tot rating make it suitable for linear regulator pass elements. At 5 A output and 7 V dropout, it dissipates 35 W; thus, operation requires ceramic PCB mounting and careful thermal design to stay within 175 °C T_j.

What base drive current is required to fully saturate PHPT60610NYX at 10 A collector current?

A minimum base current (I_B) of 1 A is required for full saturation at I_C = 10 A, per the R_CE(sat) test condition. With h_FE = 50–100, a design margin of I_B = 1.2–1.5 A ensures robust saturation across temperature and process variation, especially in automotive environments.
