Product details
Overview
PBSS302PX,115 from Nexperia is a PNP low VCE(sat) transistor in SOT89 package, rated for −20 V VCEO, −5.1 A IC, and 32 mΩ RCE(sat) at −4 A/−200 mA drive, used as a high-efficiency power switch in DC-DC converters and motor control circuits.
For engineers reviewing the PBSS302PX,115 datasheet, PBSS302PX,115 pinout, PBSS302PX,115 application, or PBSS302PX,115 equivalent, key selection criteria include verified low saturation resistance, thermal performance on FR4 PCBs, junction temperature limits up to 150 °C, and compatibility with gate-driving and charging circuit topologies requiring robust PNP switching.
Technical Context
This PNP bipolar transistor operates with a typical hFE of 160 at −6 A and −2 V VCE, supporting high-current linear and saturated switching modes. Its low VCE(sat) (160–230 mV at −5.1 A/−255 mA) minimizes conduction loss in high-duty-cycle applications.
Switching performance includes ton = 65 ns and toff = 350 ns under −12.5 V VCC, −3 A IC, and ±0.15 A base drive, enabling use in medium-frequency PWM power stages. Thermal resistance Rth(j-a) is 76 K/W on FR4 with 6 cm² collector pad, confirming suitability for thermally constrained layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −20 V - Maximum safe collector-emitter voltage with base open; defines blocking capability in high-side PNP switches. |
| IC | −5.1 A - Continuous DC collector current rating; supports sustained load switching without derating at Tamb ≤ 25 °C. |
| RCE(sat) | 32 mΩ (typ) at −4 A/−200 mA - Low on-resistance reduces power dissipation to <130 mW at 4 A, easing thermal design. |
| hFE | 100–160 at −6 A - High DC current gain enables efficient base drive with modest IB, reducing driver stage complexity. |
| toff | 350 ns - Fast turn-off time supports PWM operation up to ~500 kHz in non-resonant topologies. |
| Tj(max) | 150 °C - Maximum junction temperature; allows operation in industrial ambient environments up to 100 °C with appropriate PCB copper area. |
| Ptot | 2.1 W on ceramic PCB - Total power dissipation limit defines maximum continuous output power before thermal shutdown. |
Pinout & Package
SOT89 (SC-62/TO-243) plastic surface-mount package: 3-lead, 1.5 mm pitch, 4.5 mm × 2.5 mm × 1.5 mm body; collector tab provides thermal path to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter | Reference terminal for PNP current flow; connected to higher potential rail in high-side switch configurations. |
| 2 | Collector | Main current output node; electrically and thermally tied to large copper pour for heat dissipation. |
| 3 | Base | Control input; requires negative current injection (−200 mA typical) to saturate transistor at full load. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | 160–230 mV at −5.1 A ensures <1.2 W conduction loss, reducing heatsink requirements in compact power modules. |
| High IC capability | −5.1 A continuous rating supports direct driving of small motors, fans, and battery charging paths without external current amplification. |
| Enhanced hFE at high IC | 160 at −6 A enables stable saturation with moderate base drive, simplifying gate-driver interface design for MOSFET pre-drivers. |
| Small PCB footprint | SOT89 package occupies 11.25 mm² board area-40% smaller than TO-220 equivalents-enabling dense DC-DC converter layouts. |
| Thermal robustness | Rth(j-sp) = 20 K/W to solder point allows reliable operation with standard reflow profiles and no forced airflow. |
Applications
| DC-to-DC Conversion | MOSFET Gate Driving |
|---|---|

| Motor Control | Charging Circuits |
|
Use Scenario: Bidirectional DC motor H-bridge upper-arm switch for 24 V, 3 A brushed motor in HVAC actuator. IC Role / Device Role / Timing Role: High-side current source delivering controlled forward/reverse current; handles repetitive 10.2 A pulse loads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low VCE(sat) transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS30200PZT1G | VCEO = −20 V, IC = −3.8 A, RCE(sat) = 45 mΩ @ −3 A - lower current rating and higher saturation resistance. | Less suitable for >4 A continuous loads; requires larger base drive due to lower hFE (80 typ). | Select when space-constrained designs prioritize footprint over current headroom, and thermal budget permits +18% conduction loss. |
| Diodes Incorporated DXT30200P5-13 | VCEO = −20 V, IC = −5.0 A, RCE(sat) = 35 mΩ @ −4 A - near-identical electrical specs but SOT-23 package limits thermal performance. | Lower Ptot (0.5 W vs. 2.1 W) restricts use to low-duty-cycle or pulsed applications only. | Choose only for ultra-compact signal-level switching where PCB area is critical and average power <300 mW. |
Compared with PBSS302PX,115, NSS30200PZT1G trades current capacity and efficiency for marginally smaller size, while DXT30200P5-13 matches current rating but sacrifices thermal headroom due to inferior package thermal resistance-making PBSS302PX,115 the sole option for sustained >3 A conduction with <1 W loss.

FAQ
What is the maximum allowable base current for continuous operation?
The datasheet specifies IB = −255 mA at IC = −5.1 A for VCE(sat) testing, but continuous base current must be limited to −200 mA per Absolute Maximum Ratings table. Exceeding this risks metallization failure and permanent hFE degradation, especially above 85 °C ambient.
Can PBSS302PX,115 replace an NPN transistor in a circuit?
No-it is a PNP device with opposite polarity and complementary functionality. Direct substitution would invert logic states and reverse current direction. The NPN complement is PBSS302NX, which shares identical package, voltage, and current ratings but requires positive base drive and sinks current instead of sourcing it.
How does thermal performance differ between FR4 and ceramic PCB mounting?
On FR4 with 6 cm² collector pad, Rth(j-a) = 76 K/W enables 1.65 W dissipation at 25 °C ambient; on Al2O3 ceramic, Rth(j-a) drops to 60 K/W, raising Ptot to 2.1 W. This 27% increase in power handling directly extends safe operating area in high-temperature environments.
Is PBSS302PX,115 qualified for automotive applications?
No-the October 2025 datasheet revision explicitly states "Product(s) changed to non-automotive qualification" and directs users to Nexperia's −Q automotive-grade alternatives. It lacks AEC-Q101 stress testing, PPAP documentation, and extended temperature validation required for automotive deployment.
