Nexperia USA Inc. PHPT60415PYX

Overview

PHPT60415PYX from Nexperia is a PNP high-power bipolar transistor in LFPAK56 (SOT669) package, rated for −40 V V_CEO, −15 A continuous collector current, and 25 W total power dissipation at T_amb ≤ 25 °C; designed for automotive-grade load switching and linear voltage regulation with AEC-Q101 qualification.

For engineers reviewing the PHPT60415PYX datasheet, PHPT60415PYX pinout, PHPT60415PYX application, or PHPT60415PYX equivalent, key selection criteria include R_CEsat ≤ 57 mΩ at −15 A/−1.5 A drive, thermal resistance to mounting base of 6 K/W, operation up to 175 °C junction temperature, and compatibility with FR4 or ceramic PCB layouts per SOT669 footprint.

Technical Context

This PNP bipolar transistor uses silicon planar epitaxial technology with optimized emitter-base geometry for high-current saturation performance and low V_BEsat (≤ −1.4 V at −15 A). Its LFPAK56 package integrates a large copper mounting base directly connected to the collector terminal, enabling efficient heat transfer to the PCB.

It operates in linear mode with h_FE = 30–45 at −15 A and exhibits fast switching (t_on = 210 ns, t_off = 235 ns) under pulsed conditions (V_CC = −12.5 V, I_C = −8 A), supporting high-efficiency motor drive and relay replacement where precise analog control and thermal robustness are required.

Key Specifications

Pinout & Package

PHPT60415PYX is housed in the LFPAK56 (SOT669) surface-mount plastic package - a 4-lead Power-SO8 variant with an exposed copper mounting base electrically connected to the collector. The package features enhanced thermal performance over DPAK and reduced PCB area requirements.

FAQ

Is PHPT60415PYX pin-compatible with standard TO-220 or DPAK PNP transistors?

No - PHPT60415PYX uses the LFPAK56 (SOT669) 4-lead surface-mount package with three emitter pins and an integrated collector mounting base. It is not mechanically or electrically pin-compatible with through-hole TO-220 or 3-lead DPAK packages; PCB layout and thermal pad routing must follow Nexperia's sot669_fr footprint guidelines.

What base drive current is required to fully saturate PHPT60415PYX at −15 A collector current?

Full saturation at −15 A requires −1.5 A DC base current, as specified in the R_CEsat test condition (IC = −15 A, IB = −1.5 A). For pulsed operation (tp ≤ 300 µs), this drive level achieves R_CEsat ≤ 57 mΩ; insufficient base current increases V_CEsat and conduction loss disproportionately.

Can PHPT60415PYX be used in avalanche mode for inductive load suppression?

No - PHPT60415PYX is not rated for repetitive avalanche energy. Its absolute maximum V_CEO is −40 V with no specified E_AS (avalanche energy) rating. Inductive switching must use external flyback diodes or snubbers; operation beyond −40 V risks permanent breakdown.

Does PHPT60415PYX require a heatsink when operating at −15 A continuous current?

Not necessarily - with proper PCB layout (≥6 cm² copper pour on FR4 or ceramic substrate), its R_th(j-mb) = 6 K/W and P_tot = 25 W allow full −15 A operation at T_amb ≤ 25 °C without an external heatsink. Derating applies above 25 °C ambient; thermal simulation using Fig. 1 power derating curves is recommended for elevated temperatures.
