Product details
Overview
PHPT61003NYX from Nexperia is a 100 V, 3 A NPN high-power bipolar transistor in LFPAK56 (SOT669) package, designed for linear-mode voltage regulation and high-current load switching. It delivers RCE(sat) of 75–110 mΩ at IC = 3 A / IB = 300 mA, supports continuous operation up to Tj = 175 °C, and is AEC-Q101 qualified for automotive power management systems.
For engineers reviewing the PHPT61003NYX datasheet, PHPT61003NYX pinout, PHPT61003NYX application, or PHPT61003NYX equivalent, key selection criteria include its low saturation resistance, thermal robustness on FR4 PCBs, junction-to-solder-point thermal resistance of 6 K/W, and compatibility with high-temperature linear-mode operation in automotive and industrial power stages.
Technical Context
This NPN bipolar transistor operates in linear mode with precise VBE(sat) control (0.86–1.2 V at IC = 2 A), enabling stable current sourcing in analog-regulated loads. Its hFE ranges from 10 to 40 at IC = 3 A, supporting predictable base drive design without gain-dependent instability.
Thermal performance is defined across three mounting conditions: Rth(j-a) = 115 K/W on standard FR4, 50 K/W with 6 cm² collector pad, and 30 K/W on ceramic Al₂O₃ - enabling accurate derating per PCB layout. Transient thermal impedance curves support pulsed-load analysis up to 1 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - Maximum safe collector-emitter voltage under open-base condition; enables use in 48 V automotive bus and industrial 24–48 V systems. |
| IC | 3 A continuous - Rated DC collector current; supports sustained loadswitching in power supplies and motor drivers. |
| RCE(sat) | 75–110 mΩ at IC = 3 A / IB = 300 mA - Low conduction loss reduces heat generation and improves efficiency in linear regulators. |
| Tj(max) | 175 °C - Junction temperature limit; allows operation in under-hood automotive environments without forced cooling. |
| AEC-Q101 | Qualified - Meets stress-test requirements for discrete semiconductors in automotive applications, including temperature cycling and HTRB. |
| Rth(j-sp) | 6 K/W - Junction-to-solder-point thermal resistance; enables direct thermal modeling from die to PCB copper plane. |
| fT | 140 MHz - Transition frequency; sufficient for fast-switching auxiliary control paths and feedback loops. |
Pinout & Package
PHPT61003NYX uses the LFPAK56 (SOT669) surface-mount plastic package - a 4-terminal Power-SO8 variant with integrated mounting base. The package features an exposed collector pad for enhanced thermal conduction and mechanical stability on PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter | Primary emitter connection; electrically tied to pins 2 and 3 - forms low-inductance parallel emitter path for high-current handling. |
| 2 | Emitter | Redundant emitter terminal; reduces bond-wire inductance and current density per terminal during 3 A operation. |
| 3 | Emitter | Third emitter terminal; improves thermal spreading and current sharing across multi-layer PCB layouts. |
| 4 | Base | Control input for bipolar conduction; requires 300 mA drive for full saturation at 3 A collector current. |
| Mounting Base | Collector | Exposed metal pad - serves as primary collector terminal and thermal interface; must be soldered to ≥6 cm² copper area for rated 25 W dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| High thermal power dissipation | 25 W at Tamb ≤ 25 °C on optimized FR4 - enables compact heatsinkless designs in space-constrained modules. |
| Reduced PCB footprint vs DPAK | LFPAK56 occupies ~30% less board area than DPAK while delivering superior Rth(j-a) performance. |
| AEC-Q101 qualification | Validated for automotive under-hood use including 1000-cycle temperature cycling and 1000-hour HTRB testing. |
| Linear-mode voltage regulator support | Stable hFE and VCE(sat) over −55 °C to 175 °C enable precision analog regulation without gain collapse. |
| Low RCE(sat) at high current | 75 mΩ typical at 3 A ensures <1 W conduction loss - critical for thermally limited linear pass elements. |
Applications
| Automotive Load Switch | Industrial Linear Regulator |

Use Scenario: High-side power distribution for ADAS camera modules and infotainment ECUs in 12 V/48 V hybrid architectures. IC Role / Device Role / Timing Role: NPN bipolar pass element controlling output voltage via base bias; operates in linear region for ripple-free supply. Use Value: AEC-Q101 qualification and 175 °C Tj rating ensure reliability in engine bay proximity; low RCE(sat) minimizes self-heating during continuous 2.5 A load. |
Use Scenario: Precision 5 V/3 A output stage for programmable logic controllers requiring low-noise, non-switching power. IC Role / Device Role / Timing Role: Linear pass transistor regulated by external op-amp feedback loop; maintains constant VOUT under dynamic load steps.

| Backlight LED Driver | Power Management Unit (PMU) |
|
Use Scenario: Constant-current driver for high-brightness LCD backlight strings in automotive instrument clusters. IC Role / Device Role / Timing Role: Current-sinking NPN transistor controlled by PWM-modulated base signal; regulates LED string current in analog dimming mode. Use Value: Fast switching (ton = 320 ns, toff = 1300 ns) supports >1 kHz dimming frequencies; low VCE(sat) (225–330 mV) preserves headroom for 3–4 LED stacks. |
Use Scenario: Secondary-side overcurrent protection and sequencing switch in multi-rail industrial PMUs. IC Role / Device Role / Timing Role: High-current shutoff device activated by fault-detection circuitry; latches off during overtemp or short-circuit events. Use Value: 8 A peak collector current (ICM) handles surge currents during hot-plug events; 100 V VCEO provides margin against bus transients in 24 V systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-power NPN bipolar transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PHPT61003PY | PNP complement with identical VCEO, IC, and RCE(sat); same LFPAK56 package and AEC-Q101 qualification. | Used in complementary high-side switches or push-pull configurations where PNP topology is required. | Select when designing symmetric output stages or needing matched thermal/electrical behavior in dual-transistor topologies. |
| BUK9Y117-100B | 100 V, 7.5 A N-channel TrenchMOS; RDS(on) = 11.7 mΩ @ 10 VGS; no base drive requirement but higher gate charge. | Suitable for high-efficiency switching applications; not rated for linear-mode operation above 150 °C. | Prefer for PWM-driven loads where switching loss dominates; avoid for analog regulation due to lack of linear-region stability and lower Tj(max). |
Compared with PHPT61003PY, PHPT61003NYX offers NPN polarity essential for low-side switching and emitter-follower regulation; versus BUK9Y117-100B, it provides superior thermal robustness and guaranteed linear-mode performance at 175 °C - critical for analog power stages where MOSFETs exhibit gain variation and thermal runaway risk.

FAQ
What is the maximum continuous power dissipation for PHPT61003NYX on a standard FR4 PCB?
PHPT61003NYX delivers 1.25 W continuous power dissipation on a standard FR4 PCB with single-sided copper and tin-plated footprint. This value rises to 3 W with a 6 cm² collector mounting pad and 5 W on ceramic Al₂O₃ substrates - all specified at Tamb ≤ 25 °C per IEC 60134 limiting values.
Does PHPT61003NYX support linear-mode operation at junction temperatures above 150 °C?
Yes - PHPT61003NYX is rated for continuous operation up to Tj = 175 °C and maintains stable hFE and VCE(sat) across that range, as verified in Figures 4 and 8 of the datasheet. Its AEC-Q101 qualification includes 1000-hour high-temperature reverse bias testing at 175 °C.
How many emitter terminals does PHPT61003NYX have, and why?
PHPT61003NYX has three dedicated emitter terminals (pins 1, 2, and 3) in its LFPAK56 package. This triple-emitter configuration reduces current density per bond wire, lowers parasitic inductance, and improves thermal spreading - directly supporting reliable 3 A continuous conduction without localized heating or saturation voltage drift.
Can PHPT61003NYX replace TO-220 or DPAK transistors in existing designs?
Yes - PHPT61003NYX offers comparable electrical ratings to DPAK-packaged NPN transistors (e.g., MJD127) but in a 30% smaller LFPAK56 footprint. Its mounting base serves as the collector terminal, requiring PCB redesign to accommodate the exposed pad and four-pin layout, yet delivers better thermal resistance and reduced assembly height.
