Nexperia USA Inc. PHPT61002NYCX

Overview

PHPT61002NYCX from Nexperia is a 100 V, 2 A NPN high-power bipolar transistor in LFPAK56 (SOT669) package, designed for linear-mode voltage regulation and load switching in industrial power management systems. It delivers 80 mΩ typical R_CE(sat) at I_C = 2 A / I_B = 200 mA, supports 175 °C junction operation, and achieves 6 A peak collector current in single-pulse mode.

For engineers reviewing the PHPT61002NYCX datasheet, PHPT61002NYCX pinout, PHPT61002NYCX application, or PHPT61002NYCX equivalent, key selection criteria include thermal resistance to solder point (6 K/W), low saturation resistance under pulsed conditions, high-temperature ambient capability (−55 to 175 °C), and compatibility with FR4 PCB layouts using standard 6 cm² collector pad footprints.

Technical Context

This device operates as a high-current, high-voltage NPN switch optimized for linear-mode applications where precise V_CE(sat) control and thermal stability are critical. Its LFPAK56 package integrates a large-area mounting base directly connected to the collector terminal, enabling low R_th(j-sp) = 6 K/W and efficient heat transfer to the PCB.

The transistor exhibits DC current gain (h_FE) of 100 at I_C = 3 A (pulsed), 150 MHz f_T, and fast switching performance with t_on = 320 ns and t_off = 1300 ns under defined test conditions (V_CC = 12.5 V, I_C = 1 A).

FAQ

What is the maximum continuous collector current for PHPT61002NYCX?

The maximum continuous collector current is 2 A at T_amb ≤ 25 °C with appropriate PCB copper area (6 cm² collector pad). Derating applies above 25 °C per Figure 1 in the datasheet, reaching zero at 125 °C ambient under standard FR4 mounting conditions.

Can PHPT61002NYCX be used in linear regulator designs?

Yes - it is explicitly qualified for linear-mode voltage regulation per its datasheet Applications section. Its low R_CE(sat), high T_j rating (175 °C), and stable h_FE across temperature make it suitable for pass-element roles where thermal management relies on PCB copper rather than external heatsinks.

How does the LFPAK56 package improve thermal performance over DPAK?

The LFPAK56 package reduces R_th(j-a) by up to 50% versus DPAK on FR4 PCBs due to its larger, exposed collector mounting base and optimized internal bond-wire geometry. This yields R_th(j-sp) = 6 K/W - enabling direct thermal coupling to PCB copper without thermal vias or additional interface materials.

What is the base drive requirement to achieve full saturation at 2 A collector current?

A pulsed base current of 200 mA is required to achieve R_CE(sat) ≤ 150 mΩ at I_C = 2 A, per Table 1 and Table 7. This corresponds to I_C/I_B = 10, confirming robust saturation margin and minimizing storage time during turn-off.
