Product details
Overview
PHPT610030NK from Nexperia is an NPN/NPN high-power double bipolar transistor in LFPAK56D (SOT1205) package, designed for dual-channel switching and linear regulation. It delivers 3 A per transistor, supports 100 V VCEO, operates up to 175 °C junction temperature, and achieves 75–110 mΩ RCE(sat) at 3 A/0.3 A drive - enabling compact motor control and load-switching designs.
For engineers reviewing the PHPT610030NK datasheet, PHPT610030NK pinout, PHPT610030NK application, or PHPT610030NK equivalent, key selection criteria include dual-transistor thermal coupling, low saturation resistance under high-current pulsed operation, PCB-mount thermal performance on FR4 with 6 cm² collector pad, and compatibility with relay-replacement topologies requiring matched gain and timing.
Technical Context
This device integrates two matched NPN transistors in a single LFPAK56D thermally optimized power package. Each transistor features independent emitter-base-collector terminals with shared thermal baseplate, enabling synchronous or complementary switching without cross-coupling. The structure supports linear-mode operation with stable hFE (150–250 at 500 mA) and low VBE(sat) (0.86–1.2 V).
Thermal design is defined by dual-path dissipation: junction-to-solder-point resistance is 6 K/W, while junction-to-ambient varies from 50 K/W (FR4, 6 cm² pad) to 120 K/W (standard footprint). Transient thermal impedance curves confirm suitability for repetitive pulse loads up to 1 ms with duty cycles ≥0.01.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - Enables use in 48 V industrial bus and 24 V motor-control systems without derating. |
| IC | 3 A continuous per transistor - Supports sustained load currents in DC-DC pre-regulators and LED backlight drivers. |
| RCE(sat) | 75–110 mΩ at IC = 3 A, IB = 0.3 A - Reduces conduction loss to ≤1 W per channel at full load. |
| hFE | 150–250 at VCE = 10 V, IC = 500 mA - Ensures reliable base-drive margin with standard logic-level drivers. |
| Tj(max) | 175 °C - Allows operation in sealed enclosures or high-ambient environments like engine bay proximity. |
| toff | 1300 ns - Sufficient for PWM frequencies up to ~100 kHz in linear regulator or soft-switched load control. |
| fT | 140 MHz - Confirms adequate small-signal bandwidth for feedback-loop compensation in analog regulators. |
Pinout & Package
PHPT610030NK uses the LFPAK56D (SOT1205) surface-mount plastic package: 8-lead, dual-LFPAK layout with exposed copper mounting base for enhanced thermal transfer. Dimensions: 4.7 × 5.3 × 1.3 mm (L × W × H), with 1.27 mm pitch and 6 cm² recommended collector pad area on FR4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E1 | Emitter of transistor TR1 - Connected to low-side return path; electrically isolated from E2. |
| 2 | B1 | Base of transistor TR1 - Requires 50–300 mA drive for full saturation; decoupling critical near this pin. |
| 3 | E2 | Emitter of transistor TR2 - Independent return node; enables floating or differential emitter configurations. |
| 4 | B2 | Base of transistor TR2 - Fully isolated from B1; supports asynchronous or phase-shifted gate control. |
| 5 & 6 | C2 | Collector of TR2 - Dual-pin paralleling reduces current density and bond-wire inductance at high di/dt. |
| 7 & 8 | C1 | Collector of TR1 - Dual-pin layout improves thermal spreading into PCB copper and lowers effective Rth(j-sp). |
Key Features
| Feature | Design Value |
|---|---|
| High thermal power dissipation | 25 W per device on ceramic PCB (Al2O3) - Enables >2× power density vs. DPAK in space-constrained inverters. |
| Reduced PCB requirements | No external heatsink needed below 10 W dissipation on FR4 with 6 cm² pad - cuts board area and assembly cost. |
| High-temperature operation | Rated for continuous 175 °C junction temperature - eliminates derating in automotive under-hood or industrial HVAC modules. |
| Matched dual-transistor characteristics | hFE, VCE(sat), and toff tracked within ±15% across both transistors - simplifies balanced push-pull or H-bridge design. |
| Low saturation resistance | 75 mΩ typical RCE(sat) at 3 A - limits conduction loss to 675 mW per channel, easing thermal management. |
Applications
| Motor Control | Power Management |
|---|---|
|
Use Scenario: Brushed DC motor driver in industrial actuators with bidirectional PWM control and stall protection. IC Role / Device Role / Timing Role: Dual NPN configuration used in half-bridge topology with external flyback diodes; TR1 and TR2 switch complementary phases. Use Value: Matched hFE and toff ensure symmetrical turn-on/turn-off timing, minimizing shoot-through risk during dead-time transitions. |
Use Scenario: High-current linear voltage regulator for FPGA core supply where low-noise and fast transient response are required. IC Role / Device Role / Timing Role: TR1 acts as pass transistor; TR2 provides current-sense amplification and foldback protection via emitter degeneration. Use Value: Low VBE(sat) (0.86 V typ.) and tight VBE tracking enable accurate current limiting without external sense resistors. |
| Load Switch | Backlighting Applications |
|
Use Scenario: 24 V/3 A system-level load switch for PLC I/O modules with reverse-polarity and overcurrent protection. IC Role / Device Role / Timing Role: TR1 handles main load current; TR2 monitors emitter voltage drop for analog current limiting and thermal foldback. Use Value: Integrated dual-transistor structure eliminates inter-device propagation delay, enabling sub-µs fault response in safety-critical shutdown. |
Use Scenario: CCFL or high-brightness LED backlight driver in medical displays requiring precise current regulation and dimming linearity. IC Role / Device Role / Timing Role: TR1 controls series current; TR2 implements analog dimming via base-voltage modulation synchronized to PWM dimming signal. Use Value: Linear-mode VCE(sat) stability across temperature ensures <±2% current drift from −40 °C to +85 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN high-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PHPT610030NPK | NPN/PNP complement pair; identical package and voltage/current ratings but opposite polarity per channel. | Required for complementary-symmetry output stages (e.g., Class AB audio, push-pull converters) where one channel must sink and the other source. | Select when designing circuits needing matched gain and thermal coupling between NPN and PNP devices - not interchangeable for same-polarity use. |
| PHPT610030PK | PNP/PNP dual transistor; same LFPAK56D package, 100 V VCEO, 3 A IC, but inverted polarity and lower |hFE| (100–200). | Suitable for high-side switching or negative-rail regulation where sourcing capability is required instead of sinking. | Choose only for high-side load control or inverted logic interfaces; cannot replace PHPT610030NK in low-side or NPN-biased topologies. |
Compared with PHPT610030NPK and PHPT610030PK, the PHPT610030NK uniquely supports dual low-side switching with highest hFE and lowest RCE(sat), making it optimal for motor H-bridges and positive-rail linear regulators where NPN drive simplicity and efficiency are prioritized.

FAQ
What is the maximum safe operating current for PHPT610030NK in continuous DC mode?
The absolute maximum collector current is 3 A per transistor under Tamb ≤ 25 °C with proper PCB thermal design. In practice, continuous operation above 2.2 A requires ≥6 cm² copper pad on FR4 and airflow ≥1 m/s to maintain Tj < 150 °C. Derating curves in Figure 1 confirm 1.8 A max at 75 °C ambient with standard footprint.
Can PHPT610030NK be used in linear voltage regulator applications?
Yes - its 25 W total power dissipation (on ceramic PCB), low RCE(sat), and stable hFE across temperature make it suitable for medium-power linear regulators. Designers must limit VIN–VOUT × ILOAD to ≤15 W on FR4 with 6 cm² pad and implement thermal foldback using TR2's emitter voltage sensing.
How does the dual-pin collector layout (pins 5+6 and 7+8) affect PCB layout?
The duplicated collector pins reduce current density per bond wire and improve thermal spreading into the PCB copper. Layout best practice requires symmetric copper pours connecting both C1 pins (7+8) and both C2 pins (5+6) to the same net, with ≥0.5 mm trace width and direct connection to the main thermal pad - avoiding vias or narrow necks that increase resistance or inductance.
Is PHPT610030NK qualified for automotive applications?
No - the revision history explicitly states this part was changed to non-automotive qualification in v.3 (20241008). Automotive alternatives are designated with "-Q" suffix (e.g., PHPT610030NK-Q) and undergo AEC-Q101 stress testing; PHPT610030NK lacks those qualifications and should not be used in safety-critical or vehicle-mounted systems.
