Product details
Overview
PBSS4350SS from Nexperia is a dual NPN low VCEsat (BISS) transistor in SO8 (SOT96-1) package, designed for high-efficiency switching in space-constrained dual-load applications. It delivers 50 V VCEO, 2.7 A continuous collector current per transistor, and ultra-low 90–130 mΩ RCEsat at IC = 2 A / IB = 200 mA - enabling compact motor/fan drivers with reduced thermal footprint.
For engineers reviewing the PBSS4350SS datasheet, PBSS4350SS pinout, PBSS4350SS application, or PBSS4350SS equivalent, key selection criteria include dual-transistor layout compatibility, sub-300 mV VCEsat at full rated current, thermal resistance down to 63 K/W on ceramic PCB, and validated automotive-grade reliability per IEC 60134 limiting values.
Technical Context
This device integrates two independent NPN BISS transistors in a single SO8 package, sharing no internal connection between channels. Each transistor features optimized base doping and epitaxial structure to achieve high hFE (120–520) across 100 mA–2.7 A IC range while maintaining low saturation voltage.
Switching performance is characterized by 104 ns turn-on time and 520 ns turn-off time under 10 V VCC, 2 A IC, ±100 mA base drive - enabled by minimized minority-carrier storage and low Cc (18–25 pF). Thermal design leverages dual-collector pins (pins 5/6 and 7/8) for enhanced heat spreading on FR4 or Al2O3 substrates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - supports 24 V automotive and industrial bus systems with 100 % margin against transients. |
| IC (continuous) | 2.7 A per transistor - enables direct driving of small DC motors or cooling fans without external current boosting. |
| RCEsat | 90–130 mΩ at IC = 2 A / IB = 200 mA - reduces conduction loss to ≤520 mW per channel at full load. |
| hFE | 120–180 at IC = 2.7 A - ensures stable saturation with modest base drive (≤270 mA), easing MCU GPIO interface. |
| toff | 520 ns - supports PWM switching up to 500 kHz with minimal dead-time overhead in dual-channel control. |
| Ptot (per device) | 2.0 W on ceramic PCB - allows dual-transistor operation at ambient temperatures up to +100 °C without heatsink. |
Pinout & Package
Package: SO8 (SOT96-1), 3.9 mm body width, 1.27 mm lead pitch, standard footprint compatible with automated SMT assembly and reflow/wave soldering per IPC-7351.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter TR1 | Low-impedance return path for first transistor; tied to PCB ground plane for thermal and EMI control. |
| 2 | Base TR1 | Direct CMOS/TTL-compatible control input; requires ≥270 mA peak drive for full saturation at 2.7 A IC. |
| 3 | Emitter TR2 | Independent emitter node for second transistor; enables separate load referencing or floating configurations. |
| 4 | Base TR2 | Isolated control input for second channel; supports independent or complementary PWM timing. |
| 5, 6 | Collector TR2 | Dual-collector configuration lowers thermal resistance and improves current sharing under pulse loads. |
| 7, 8 | Collector TR1 | Parallel collector terminals maximize power handling and reduce bond-wire inductance for fast switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN topology | Two electrically isolated transistors in one SO8 package - eliminates inter-device layout mismatch and saves ≥30 % board area vs discrete pairs. |
| Low RCEsat | 90–130 mΩ at IC = 2 A - cuts conduction loss by >40 % versus standard bipolar transistors, reducing heatsink requirements. |
| High hFE at high current | 120–180 at IC = 2.7 A - enables direct drive from 3.3 V/5 V microcontrollers without base resistors or driver stages. |
| Thermal optimization | Rth(j-a) = 63 K/W on ceramic PCB - sustains 2.0 W total dissipation at Tamb = +100 °C, critical for under-hood automotive modules. |
| Automotive-qualified | Rated for −65 °C to +150 °C Tj; compliant with IEC 60134 absolute maximum ratings - suitable for engine control and HVAC actuators. |
Applications
| Automotive HVAC Blower Control | Industrial Dual-Channel Fan Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PBSS4350SPN | Same die, PNP/NPN complement in same SO8 package - provides matched characteristics but inverted polarity per channel. | Required when circuit topology demands one NPN and one PNP switch (e.g., level-shifting or complementary output stages). | Select only if complementary polarity is needed; not a drop-in replacement for dual-NPN use cases. |
| PBSS5350SS | Higher VCEO (80 V) and lower IC (1.5 A); RCEsat 120–180 mΩ - optimized for higher-voltage, lower-current industrial solenoids. | Suitable for 48 V telecom or factory automation loads where voltage margin outweighs current capability. | Choose when system bus exceeds 50 V; avoid for 24 V/2.7 A motor drives due to insufficient current rating. |
Compared with PBSS4350SPN and PBSS5350SS, the PBSS4350SS uniquely balances 50 V rating, 2.7 A current, and 90 mΩ RCEsat in a dual-NPN configuration - making it the only option for compact, thermally efficient 24 V dual-motor control without compromising drive strength or thermal headroom.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum base current (IB) is 0.5 A per transistor, as specified in Table 6. However, for reliable long-term operation at 2.7 A collector current, the datasheet recommends IB = 270 mA (hFE = 120–180 range). Exceeding 300 mA continuously risks accelerated degradation of base-emitter junction integrity and reduced thermal stability.
Can PBSS4350SS be used in linear amplification mode?
No - the PBSS4350SS is optimized exclusively for switching applications. Its BISS structure prioritizes low saturation voltage and high current gain at high IC, not linearity or frequency response. The datasheet provides no small-signal parameters (e.g., fT, hfe bandwidth), and thermal limitations (Ptot = 2.0 W max) make linear operation impractical beyond brief transient conditions.
How does the dual-collector pin configuration affect PCB layout?
Pins 5/6 serve as parallel collectors for TR2 and pins 7/8 for TR1 - this requires connecting both pins in each pair to the same high-current net (e.g., motor supply rail) using wide copper pours. Doing so reduces effective bond-wire inductance by ~30 % and lowers thermal resistance by enabling dual thermal paths to the PCB, directly improving switching speed and power handling.
Is PBSS4350SS qualified to AEC-Q101 standards?
While the PBSS4350SS meets automotive ambient temperature (−65 °C to +150 °C) and IEC 60134 limiting values, Nexperia's official AEC-Q101 qualification status for this specific part number is not declared in the Rev. 01 datasheet. For AEC-Q101-compliant alternatives, consult Nexperia's automotive-grade portfolio (e.g., PBSS4350X series) or request formal qualification documentation from their automotive support team.
