Product details
Overview
PHPT61002PYCX from Nexperia is a PNP high-power bipolar transistor in LFPAK56 (SOT669) package, rated for −100 V VCEO, −2 A continuous collector current, and 25 W power dissipation at Tamb ≤ 25 °C. It serves as a robust load switch or linear regulator pass element in industrial power management systems operating up to 175 °C junction temperature.
For engineers reviewing the PHPT61002PYCX datasheet, PHPT61002PYCX pinout, PHPT61002PYCX application, or PHPT61002PYCX equivalent, key selection criteria include its 125–200 mΩ RCE(sat) at −2 A/−200 mA drive, thermal resistance as low as 6 K/W to solder point, and compatibility with FR4 or ceramic PCB mounting configurations.
Technical Context
This device operates as a single PNP bipolar junction transistor with emitter-connected pins 1–3 and base on pin 4, optimized for high-current switching and linear-mode regulation. Its design supports pulsed peak currents up to −6 A and maintains stable hFE (20–100) across −55 °C to +150 °C junction temperatures.
The LFPAK56 package integrates an exposed collector mounting base for direct thermal coupling, enabling efficient heat transfer via soldered copper area. Thermal performance varies significantly with PCB layout: Rth(j-a) ranges from 30 K/W (ceramic) to 115 K/W (standard FR4), while Rth(j-sp) remains fixed at 6 K/W to the solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −100 V - Maximum safe collector-emitter voltage with open base; defines blocking capability in high-side switch or linear regulator topologies. |
| IC | −2 A - Continuous DC collector current rating; determines maximum sustained load current in power management circuits. |
| RCE(sat) | 125–200 mΩ - On-state resistance at −2 A/−200 mA drive; directly impacts conduction loss and thermal rise in load-switch applications. |
| Ptot | 25 W - Total power dissipation at Tamb ≤ 25 °C with specified mounting pad; sets upper limit for thermal design margin on FR4 PCBs. |
| Tj(max) | 175 °C - Maximum junction temperature; enables operation in harsh environments such as automotive under-hood or industrial motor drives. |
| fT | 125 MHz - Transition frequency at −10 V VCE, −100 mA IC; indicates usable bandwidth for moderate-speed switching control loops. |
| VBE(sat) | −1.02 to −1.2 V - Base-emitter saturation voltage at −2 A/−200 mA; determines required base drive voltage headroom and driver stage sizing. |
Pinout & Package
The PHPT61002PYCX uses the LFPAK56 (SOT669) surface-mount plastic package with an exposed collector mounting base and four terminals. Its compact 5.8 × 4.4 mm footprint provides superior thermal performance over DPAK while maintaining compatibility with standard SO-8 reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Emitter | Three parallel emitter connections reduce bond-wire inductance and improve current sharing; essential for high-current stability and reduced switching oscillation. |
| 4 | Base | Single low-impedance base terminal; requires ≥ −200 mA drive for full saturation at −2 A IC, supporting discrete or IC-based driver designs. |
| Mounting base | Collector | Exposed copper collector pad soldered directly to PCB; primary thermal path to board and mechanical anchor point for high-vibration environments. |
Key Features
| Feature | Design Value |
|---|---|
| High thermal power dissipation | 25 W at 25 °C ambient with FR4 mounting pad - enables higher output current without heatsink in space-constrained industrial modules. |
| High-temperature operation | Rated to 175 °C junction temperature - supports use in engine control units, LED drivers, and enclosed power supplies where ambient exceeds 105 °C. |
| Reduced PCB requirements vs. DPAK | 5.8 × 4.4 mm footprint with integrated thermal pad - eliminates need for large copper pour or thermal vias required by larger packages, saving board area and cost. |
| Low RCE(sat) | 125 mΩ typical at −2 A - reduces conduction losses by >30% compared to legacy TO-220 PNP transistors, improving system efficiency in battery-powered loads. |
Applications
| Power Management | Load Switch |
|---|---|
Use Scenario: Primary DC-DC converter output stage in industrial PLC power supplies delivering 24 V/1.5 A. IC Role / Device Role / Timing Role: PNP pass transistor regulating output voltage in linear mode, controlled by error amplifier feedback loop. Use Value: Low RCE(sat) minimizes dropout voltage and self-heating, allowing stable 24 V output even at full load without external heatsink. | Use Scenario: High-side power switch enabling/disabling 12 V rail to motor driver circuitry in HVAC control boards. IC Role / Device Role / Timing Role: Discrete PNP switch controlled by microcontroller GPIO through base resistor network.

IC Role / Device Role / Timing Role: High-voltage PNP switch isolating inverter primary winding during standby mode. Use Value: −100 V rating safely blocks inverter flyback spikes; 175 °C Tj(max) withstands localized heating near transformer windings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PHPT61002NYC | NPN complement with identical package, voltage, and current ratings but opposite polarity. | Requires inverted control logic and different biasing; suitable only where NPN topology is preferred (e.g., low-side switching). | Select when circuit architecture mandates NPN configuration or when pairing with this PNP in complementary output stages. |
| MBT3906DW1T1G | Smaller SOT-363 package, −40 V VCEO, −200 mA IC, no exposed thermal pad. | Limited to low-power signal switching; cannot replace PHPT61002PYCX in any high-current or high-voltage application. | Only consider for prototyping or auxiliary logic-level functions-not for functional substitution in power roles. |
Compared with PHPT61002NYC, the PHPT61002PYCX offers native high-side switching capability and thermal robustness; versus MBT3906DW1T1G, it delivers 10× higher current handling and 2.5× higher voltage blocking-making it irreplaceable in industrial load-switch and linear-regulator designs.

FAQ
What is the recommended PCB layout for optimal thermal performance of PHPT61002PYCX?
Optimal thermal performance requires a minimum 6 cm² tin-plated copper mounting pad connected to the exposed collector base, with ≥4 thermal vias (0.3 mm diameter) to inner ground planes. The datasheet specifies Rth(j-a) drops from 115 K/W (standard FR4) to 50 K/W with this pad, enabling 25 W dissipation at 25 °C ambient.
Can PHPT61002PYCX be used in avalanche mode for inductive load protection?
No-PHPT61002PYCX is not rated for repetitive avalanche operation. Its absolute maximum VCEO of −100 V applies only under clamped conditions. For inductive switching, external flyback diodes or TVS clamps must be used to prevent exceeding this rating during turn-off transients.
How does base drive requirement scale with collector current in linear mode?
In linear regulation, base current scales approximately linearly with collector current: at −500 mA IC, hFE ≈ 150 (requiring ~−3.3 mA IB); at −2 A IC, hFE drops to 20–100 (requiring −20 to −100 mA IB). Full saturation at −2 A demands −200 mA IB, per RCE(sat) test condition.
Is PHPT61002PYCX automotive qualified?
No-PHPT61002PYCX is not AEC-Q101 qualified. While it operates up to 175 °C junction temperature, it lacks automotive-specific stress testing, failure analysis reporting, and PPAP documentation. Use in automotive applications requires customer-led qualification and carries full liability per Nexperia's non-automotive disclaimer.
