Product details
Overview
PBSS5350D,125 from Nexperia is a PNP low VCEsat transistor in SOT457 (SC-74/TSOP6) package, rated for −50 V VCEO, −3 A continuous collector current, and 120–150 mΩ RCEsat; used as high-efficiency supply-line switch in battery management and DC-DC converters.
For engineers reviewing the PBSS5350D,125 datasheet, PBSS5350D,125 pinout, PBSS5350D,125 application, or PBSS5350D,125 equivalent, key selection factors include verified low saturation resistance, thermal performance on FR4 PCBs, peak current capability up to −5 A, and compatibility with reflow/wave soldering footprints per SOT457 standard.
Technical Context
This PNP transistor operates with base-driven saturation switching, delivering VCEsat ≤ −300 mV at −2 A / −200 mA drive and hFE ≥ 100 under pulsed conditions. Its low RCEsat enables reduced conduction loss in high-current switching paths.
Thermal resistance varies with PCB copper area: 208 K/W (1 cm²), 160 K/W (6 cm²), or 100 K/W (4-layer board), supporting design flexibility across power density requirements without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - maximum safe collector-emitter voltage with open base; defines off-state blocking capability in supply rail switching. |
| IC | −3 A - continuous DC collector current rating; supports stable operation in battery disconnect and load-switch circuits. |
| RCEsat | 120–150 mΩ - measured at −2 A / −200 mA, pulsed; directly determines I²R conduction loss and thermal rise in high-duty-cycle applications. |
| hFE | ≥100 - DC current gain at −2 A / −200 mA; ensures reliable saturation with moderate base drive, reducing driver-stage complexity. |
| VBEsat | ≤ −1.2 V - base-emitter saturation voltage at −2 A / −200 mA; informs base resistor sizing and driver voltage headroom requirements. |
| fT | 100 MHz - transition frequency at −5 V / −100 mA; indicates usable bandwidth for fast-switching control loops in synchronous rectification. |
| Cc | 40 pF - collector capacitance at −10 V; impacts switching speed and EMI in high-frequency DC-DC topologies. |
Pinout & Package
Package: SOT457 (SC-74 / TSOP6), 6-pin surface-mount plastic package with exposed collector terminals for thermal enhancement; footprint compliant with JEDEC MO-187AA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Collector (C) | Four parallel collector terminals reduce bond-wire inductance and improve current sharing; enable high-current routing and thermal spreading on PCB. |
| 3 | Base (B) | Sole base connection; requires precise current-limited drive to ensure full saturation without overdrive-induced delay or storage time penalty. |
| 4 | Emiter (E) | Single emitter terminal; serves as reference node for load-side switching; polarity must be observed for PNP configuration in high-side switch layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | ≤ −300 mV at −2 A ensures <1 W conduction loss, enabling compact thermal design in space-constrained battery packs. |
| High current capability | −5 A peak rating allows surge handling during inrush or fault events in DC-DC input stages without secondary protection. |
| Multi-collector topology | Four collector pins reduce effective lead resistance by ~4× vs. single-pin packages, improving current distribution and thermal dissipation. |
| Small PCB footprint | SOT457 outline (3.1 × 2.5 mm) saves >30% board area vs. TO-236 (SOT23), critical for portable and wearable power modules. |
Applications
| Battery Disconnect Switch | DC-DC Converter High-Side Switch |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low-VCEsat transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3005LPSQ-13 | −30 V VCEO, −5 A IC, 45 mΩ RCEsat; dual-die TSDFN package with thermal pad. | Higher current density but lower voltage rating; unsuitable for 48 V systems or automotive transients. | Select when board space is critical and system voltage stays ≤30 V; requires thermal pad reflow profile. |
| MMBT5401-7-F | −60 V VCEO, −0.6 A IC, 500 mΩ RCEsat; SOT23 package, no multi-collector layout. | Lower current and higher saturation resistance limit use to signal-level switching or low-power logic interfaces. | Choose only for cost-sensitive, low-current bias networks where thermal performance is secondary. |
Compared with DMT3005LPSQ-13 and MMBT5401-7-F, PBSS5350D,125 uniquely balances −50 V blocking, −3 A current, and sub-150 mΩ RCEsat in a standard SOT457 footprint-making it optimal for mid-power battery and converter applications requiring proven manufacturability and thermal headroom.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum peak base current is −1 A, but continuous operation requires limiting IB to ≤ −200 mA per datasheet test condition for VCEsat and RCEsat validation. Exceeding this risks thermal runaway due to β degradation above 125 °C junction temperature.
Can PBSS5350D,125 replace an NPN transistor in the same circuit?
No-it is a PNP device with inverted polarity; direct substitution would reverse current flow and disable switching function. An NPN complement is PBSS4350D, which shares identical package, RCEsat, and current ratings but requires reversed biasing and layout.
How does the four-collector pin configuration affect PCB layout?
All four collector pins (1, 2, 5, 6) must be routed to the same net-typically a large copper pour-to maximize thermal conduction and minimize inductance. Splitting or daisy-chaining them increases resistance and causes current imbalance, degrading RCEsat and thermal performance.
Is PBSS5350D,125 qualified for automotive applications?
No-the 2023 datasheet explicitly states it was changed to non-automotive qualification. For automotive use, Nexperia offers the −Q qualified variant PBSS5350D-Q, which undergoes AEC-Q101 stress testing and includes extended temperature and reliability validation.
