Product details
Overview
PBSS5350SS from Nexperia is a dual PNP low VCEsat BISS transistor in SO8 (SOT96-1) package, designed for high-efficiency switching in space-constrained automotive and industrial control circuits. It delivers −50 V VCEO, −2.7 A continuous IC, 95–140 mΩ RCEsat at −2 A/−200 mA drive, and operates up to 150 °C junction temperature - enabling compact dual-motor/fan drivers with reduced thermal footprint.
For engineers reviewing the PBSS5350SS datasheet, PBSS5350SS pinout, PBSS5350SS application, or PBSS5350SS equivalent, this device serves as a thermally optimized, dual-channel PNP switch where low saturation voltage, high current gain at high IC, and PCB-area efficiency are critical selection criteria.
Technical Context
This dual PNP BISS transistor integrates two independent high-gain, low-saturation transistors sharing a common SO8 thermally enhanced leadframe. Each channel supports −2.7 A DC collector current and achieves VCEsat as low as −255 mV at −2.7 A/−270 mA base drive, enabled by optimized epitaxial structure and emitter ballasting.
Thermal performance is defined across three mounting conditions: Rth(j-a) = 167 K/W (FR4, standard), 104 K/W (FR4, 1 cm² collector pad), and 63 K/W (ceramic Al₂O₃). Switching times - td = 9 ns, tr = 54 ns, toff = 240 ns - support PWM frequencies up to ~500 kHz in motor gate drive and load switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum blocking voltage per transistor; enables use in 24 V automotive systems with margin against load dump transients. |
| IC (continuous) | −2.7 A - Sustained collector current per channel; supports dual 2 A fan/motor loads without parallel devices. |
| RCEsat | 95–140 mΩ at −2 A/−200 mA - Directly determines conduction loss (Pcond ≈ I² × R); reduces heat generation vs. standard PNP transistors by >40%. |
| hFE | 95–135 at −2.7 A/−270 mA - High current gain at full load ensures reliable saturation with modest base drive, simplifying driver design. |
| Tj max | 150 °C - Junction temperature limit compatible with under-hood automotive environments and sealed industrial enclosures. |
| toff | 240 ns - Total turn-off delay + storage + fall time; enables fast PWM switching while maintaining low switching loss. |
Pinout & Package
Package: SO8 (SOT96-1), 8-lead surface-mount plastic package with 3.9 mm body width and exposed collector pads for thermal enhancement. Mounting requires tin-plated FR4 PCB with ≥1 cm² copper area per collector terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter TR1 | Current sink node for first PNP transistor; connects to load return path. |
| 2 | Base TR1 | Control input for TR1; requires −270 mA for full saturation at −2.7 A IC. |
| 3 | Emitter TR2 | Current sink node for second PNP transistor; electrically isolated from TR1 emitter. |
| 4 | Base TR2 | Independent control input for TR2; enables asynchronous dual-switch operation. |
| 5 & 6 | Collector TR2 | Shared high-current output node for TR2; both pins connect internally to same collector terminal. |
| 7 & 8 | Collector TR1 | Shared high-current output node for TR1; dual-pin layout improves current sharing and thermal spreading. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | −255 mV typical at −2.7 A/−270 mA - cuts conduction loss by >50% vs. conventional PNP transistors, reducing heatsink requirements. |
| Dual independent channels | Two fully isolated PNP transistors in one SO8 package - eliminates board space and assembly cost of discrete dual-transistor solutions. |
| High hFE at high IC | 95 min at −2.7 A - maintains strong saturation with minimal base drive, easing microcontroller GPIO or low-power driver IC interfacing. |
| Thermally optimized leadframe | Rth(j-sp) = 40 K/W - enables direct solder-point thermal transfer to PCB, supporting 1.43 W dissipation on FR4 with 1 cm² collector pad. |
Applications
| Automotive HVAC Blower Control | Industrial Dual Fan Speed Regulation |
|---|---|
|
Use Scenario: Controlling two independent 24 V DC blower motors in vehicle cabin HVAC systems, with PWM-based speed modulation and overcurrent protection. IC Role / Device Role / Timing Role: Dual PNP switch providing low-loss, thermally robust current sinking for each motor's low-side return path. Use Value: Eliminates need for two separate SOT-23 packages and external current-sense resistors; RCEsat < 140 mΩ ensures < 1 W total conduction loss at full load. |
Use Scenario: Regulating airflow in programmable industrial ventilation units using two variable-speed fans driven from a single controller board. IC Role / Device Role / Timing Role: Dual-channel load switch enabling independent enable/disable and PWM dimming per fan without cross-talk. Use Value: SO8 footprint saves >40% PCB area vs. dual-SOT223; Tj = 150 °C rating allows operation in enclosed cabinets up to 85 °C ambient. |
| Redundant Power Path Switching | Compact Dual-Channel Relay Replacement |
|
Use Scenario: Providing fail-safe dual-path 12 V power distribution in safety-critical embedded controllers, where either channel can carry full load if the other fails. IC Role / Device Role / Timing Role: Redundant PNP switch pair with independent base control and shared thermal management. Use Value: Matched hFE and VCEsat between channels ensure balanced current sharing; 150 °C Tj supports long-term reliability in unventilated modules. |
Use Scenario: Replacing electromechanical relays in smart home actuators (e.g., dual-zone radiator valves), requiring silent, bounce-free, and cycle-limited switching. IC Role / Device Role / Timing Role: Solid-state dual-pole switch replacing relay contacts, controlled via MCU GPIO with opto-isolated inputs. Use Value: 240 ns toff enables precise timing control; −5 A ICM handles inrush currents of solenoid loads without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3024LSDQ | Single-channel 30 V PNP BISS in TSOP6; no dual configuration, lower VCEO (−30 V), higher RCEsat (180 mΩ @ −2 A). | Suitable only for single-load applications; insufficient for dual-motor control without duplication. | Select when board space permits two separate devices and 30 V system voltage is acceptable. |
| BC847BDW1T1G | Dual PNP in SC-70-6; VCEO = −45 V, IC = −100 mA, RCEsat > 500 mΩ - not a BISS structure, limited to signal-level switching. | Only appropriate for logic-level or sensor interface loads, not power switching. | Choose only for low-current biasing or level-shifting; unsuitable for motor/fan drive due to current and loss limitations. |
Compared with DMT3024LSDQ and BC847BDW1T1G, PBSS5350SS uniquely delivers dual high-current PNP switching in one thermally efficient SO8 package - offering 2.7× higher IC than BC847BDW1T1G and true dual-channel integration absent in DMT3024LSDQ, making it the sole option for space-constrained, high-efficiency dual-load control.

FAQ
What is the maximum safe operating current per channel at 85 °C ambient?
At Tamb = 85 °C with FR4 PCB and 1 cm² collector pad, the device supports −2.7 A continuous per channel. Derating follows the 104 K/W Rth(j-a) curve: maximum allowable power dissipation drops to ~0.63 W, limiting IC to approximately −1.8 A for sustained operation without exceeding 150 °C Tj.
Can PBSS5350SS replace mechanical relays in 24 V DC applications?
Yes - its −5 A peak collector current handles typical relay inrush (e.g., solenoid coils), −50 V VCEO exceeds 24 V system requirements, and 240 ns toff enables precise timing control. Unlike relays, it offers silent operation, infinite cycle life, and no contact bounce, provided base drive meets −270 mA requirement at full load.
How does the dual-collector pin configuration (pins 5+6 and 7+8) affect PCB layout?
Pins 5 & 6 are internally shorted to TR2 collector; pins 7 & 8 to TR1 collector. This dual-pin layout increases current-handling capacity per channel and improves thermal spreading into the PCB copper. Layout must connect both pins of each collector pair to the same net and allocate ≥1 cm² of 2 oz copper per collector node for rated power handling.
Is PBSS5350SS qualified for automotive AEC-Q101 stress testing?
No - PBSS5350SS is not AEC-Q101 qualified. It is specified for industrial and general-purpose automotive applications but lacks formal qualification for mission-critical automotive subsystems (e.g., ADAS, powertrain). For AEC-Q101-compliant alternatives, consult Nexperia's Automotive BISS portfolio such as PBSS5350X.
