Product details
Overview
PHPT610035NK from Nexperia is an NPN/NPN high-power double bipolar transistor in LFPAK56D (SOT1205) package, designed for matched-pair current handling in power stages. It delivers 3 A collector current per transistor, 100 V collector-base voltage, and 75–110 mΩ RCE(sat) at IC = 3 A / IB = 300 mA, with AEC-Q101 qualification for automotive motor control and power management circuits.
For engineers reviewing the PHPT610035NK datasheet, PHPT610035NK pinout, PHPT610035NK application, or PHPT610035NK equivalent, key selection criteria include matched hFE (±5%), dual-transistor thermal coupling in a single 8-lead LFPAK56D footprint, 175 °C junction rating, and pulsed switching performance (ton = 320 ns, toff = 1300 ns).
Technical Context
This device integrates two thermally coupled NPN transistors in a single LFPAK56D package, enabling precise current mirroring and differential amplification without inter-device thermal drift. Its matched hFE (0.95–1.05 typ.) and low RCE(sat) support high-efficiency, high-current switching up to 3 A per channel under pulsed conditions (δ ≤ 0.02).
The SOT1205 package provides 25 W total power dissipation on ceramic PCB and 5 W on standard FR4 - enabled by low Rth(j-sp) of 6 K/W - making it suitable for space-constrained, high-temperature environments such as automotive body control modules and LED backlight drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCBO | 100 V - supports 48 V automotive bus systems with 2× safety margin against transients |
| IC (per transistor) | 3 A continuous - enables direct drive of small DC motors or solenoids without external buffering |
| RCE(sat) | 75–110 mΩ at IC = 3 A / IB = 300 mA - reduces conduction loss to <1 W per transistor at full load |
| hFE matching | 0.95–1.05 - ensures ≤5% current mismatch between transistors in mirror or push-pull configurations |
| Tj max | 175 °C - allows operation in under-hood automotive locations without derating below 150 °C ambient |
| toff | 1300 ns - supports PWM switching up to ~750 kHz in power management applications |
| Rth(j-sp) | 6 K/W - enables efficient heat transfer to PCB copper pour, reducing need for heatsinks |
Pinout & Package
Package: LFPAK56D (SOT1205), 8-lead surface-mount plastic package with dual exposed collector pads for enhanced thermal performance and mechanical robustness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E1 | Emitter of transistor TR1 - connected to low-side return path in half-bridge or current mirror |
| 2 | B1 | Base of transistor TR1 - driven by dedicated gate driver or microcontroller GPIO with current limiting |
| 3 | E2 | Emitter of transistor TR2 - electrically isolated from E1; enables independent biasing in differential pairs |
| 4 | B2 | Base of transistor TR2 - supports complementary or mirrored base drive schemes |
| 5, 6 | C2 | Collector of TR2 - dual-pin connection lowers inductance and improves current sharing in high-di/dt switching |
| 7, 8 | C1 | Collector of TR1 - dual-pin layout enhances thermal spreading and reduces localized heating at solder joints |
Key Features
| Feature | Design Value |
|---|---|
| Matched current gain | hFE1/hFE2 = 0.95–1.05 - eliminates manual binning for precision current mirrors |
| Thermal resistance (j-sp) | 6 K/W - enables >80% of rated power dissipation directly into PCB copper, reducing system-level cooling cost |
| AEC-Q101 qualification | Qualified for automotive grade 0/1 - supports deployment in engine control, lighting, and chassis modules without additional qualification effort |
| High-temperature operation | Rated to Tamb = 175 °C - eliminates need for external thermal sensors or derating logic in hot zones |
| Reduced PCB area vs DPAK | LFPAK56D footprint occupies ~40% less board space than equivalent DPAK - critical for compact ECUs and LED drivers |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-power matched bipolar transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PHPT610030NK | Unmatched version; same package and electrical specs but no hFE binning (±20% typical) | Suitable for non-critical switching where gain matching is unnecessary | Select when cost sensitivity outweighs precision current mirroring requirements |
| PHPT610035NPK | NPN/PNP complement pair; includes one NPN and one PNP transistor in same LFPAK56D | Enables complementary output stages (e.g., Class AB audio, push-pull drivers) | Choose for bidirectional current control or rail-to-rail output swing applications |
Compared with PHPT610035NK, PHPT610030NK sacrifices gain matching for lower unit cost, while PHPT610035NPK trades dual-NPN symmetry for complementary polarity - both retain identical thermal performance and AEC-Q101 qualification.

FAQ
What is the maximum continuous collector current per transistor?
The PHPT610035NK supports 3 A continuous collector current per transistor under Tamb ≤ 25 °C with adequate PCB copper area. Derating applies above 25 °C ambient, reaching zero current at 175 °C junction temperature. The 8 A peak rating applies only for single pulses ≤1 ms.
How does the dual-collector pin configuration (pins 5/6 and 7/8) impact PCB layout?
Pins 5/6 (C2) and 7/8 (C1) are internally paralleled collector terminals per transistor. This dual-pin design lowers parasitic inductance and improves current sharing during fast switching, requiring symmetric copper pours and equal-length traces to both pins to maintain balance and avoid thermal asymmetry.
Is PHPT610035NK suitable for linear-mode operation?
Yes - its 25 W total power dissipation (on ceramic PCB) and 175 °C Tj rating support linear-mode use in Class A/B amplifiers or precision current sources. However, safe operating area (SOA) must be verified per application, especially at high VCE and IC combinations where secondary breakdown limits apply.
What is the significance of the "LFPAK56D" package designation?
LFPAK56D denotes Nexperia's 5.6 mm × 6.0 mm dual-channel power package with 8 leads and dual exposed collector pads. It offers 30% lower Rth(j-a) than DPAK and improved mechanical reliability over SO8, optimized for automated reflow assembly and high-power density automotive PCBs.
