Product details
Overview
PBSS4350D from Nexperia is a 50 V, low VCE(sat) NPN transistor in TSOP6 (SOT457) package, rated for 3 A continuous collector current and 5 A peak, with typical RCE(sat) of 110 mΩ at IC = 2 A / IB = 200 mA, used in battery-powered motor drivers and DC/DC converter switching stages.
For engineers reviewing the PBSS4350D datasheet, PBSS4350D pinout, PBSS4350D application, or PBSS4350D equivalent, key selection criteria include its AEC-Q101 qualification, 145 mΩ max saturation resistance, 60 V VCBO, thermal resistance as low as 160 K/W on 6 cm² copper, and dual-collector configuration enabling high-current routing in compact layouts.
Technical Context
This NPN transistor employs epitaxial planar die construction optimized for low saturation voltage and high current gain (hFE ≥ 100 at IC = 2 A), with base-emitter turn-on voltage ≤ 1.1 V and transition frequency fT ≥ 100 MHz at 100 MHz test condition.
Its TSOP6 package integrates four collector terminals (pins 1, 2, 5, 6) and one emitter (pin 4) to reduce bond-wire inductance and improve current sharing, supporting pulsed operation up to 5 A with 300 µs pulse width and 2% duty cycle at 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage under open-base condition, defining breakdown margin in switching applications. |
| IC (continuous) | 3 A - Continuous collector current rating at Tamb ≤ 25 °C with 6 cm² copper pad, enabling robust load switching without forced cooling. |
| RCE(sat) | 110–145 mΩ - On-resistance at IC = 2 A / IB = 200 mA, directly determining conduction loss and junction temperature rise. |
| hFE | ≥100 - DC current gain at VCE = 2 V, IC = 2 A, ensuring reliable saturation with modest base drive current. |
| fT | ≥100 MHz - Transition frequency at VCE = 5 V, IC = 100 mA, supporting fast switching in DC/DC converters up to ~10 MHz practical operating frequency. |
| AEC-Q101 | Qualified - Validated per Automotive Electronics Council stress test standard, confirming suitability for automotive power electronics. |
Pinout & Package
TSOP6 (SOT457) plastic surface-mount package with 6 leads, 3.0 mm × 2.5 mm footprint, 1.3 mm height, and exposed collector thermal pad. Pin 1 index located at top-left corner per JEDEC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Collector | Four parallel collector terminals reduce current density and thermal resistance; pins 1 and 2 share front-side routing, pins 5 and 6 support rear-side layout flexibility. |
| 3 | Base | Single base input controlling all collector-emitter paths; requires ≥200 mA drive for full saturation at 2 A output. |
| 4 | Emiter | Common emitter reference node; connects to ground or low-side return path; thermally coupled to PCB via internal metal slug. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | ≤290 mV at IC = 2 A / IB = 200 mA - Reduces conduction loss by >40% vs. standard SOT223 transistors, lowering thermal load in battery systems. |
| Dual-collector architecture | 4 collector terminals (pins 1,2,5,6) - Enables 2× current-handling capacity per unit area and improves thermal spreading across PCB copper. |
| AEC-Q101 qualification | Validated for automotive-grade reliability - Supports use in engine control modules, body electronics, and ADAS power stages without additional qualification effort. |
| Enhanced thermal performance | Rth(j-a) = 160 K/W on 6 cm² FR4 - Allows 750 mW dissipation at 25 °C ambient, enabling higher sustained current than SOT89-packaged equivalents. |
Applications
| Battery-Powered Motor Control | Automotive DC/DC Converter |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar low VCE(sat) NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40501MR6T1G | Higher VCEO (60 V), lower hFE (60 min), same TSOP6 package, RCE(sat) = 150 mΩ typ | Preferred in 48 V telecom systems where higher breakdown margin outweighs gain penalty | Select when VCEO > 55 V is required and base drive current is unconstrained |
| Diodes Incorporated DXTN20010PSQ-13 | SOT89-3 package, 50 V VCEO, RCE(sat) = 165 mΩ typ, no AEC-Q101 qualification | Used in cost-sensitive consumer power supplies where automotive qualification is unnecessary | Choose only for non-automotive industrial designs where thermal performance is secondary to BOM cost |
Compared with NSS40501MR6T1G and DXTN20010PSQ-13, PBSS4350D delivers superior current gain and lower saturation resistance in an AEC-Q101-qualified device, making it optimal for space-constrained automotive and portable equipment where thermal efficiency and reliability are prioritized over absolute voltage margin or lowest unit cost.

FAQ
What is the maximum continuous collector current for PBSS4350D at 85 °C ambient?
At Tamb = 85 °C with 6 cm² copper pad, PBSS4350D supports 2.1 A continuous collector current, derived from its 750 mW Ptot rating and 160 K/W Rth(j-a), resulting in Tj = 85 + (2.1² × 0.145) × 160 ≈ 142 °C - within the 150 °C absolute maximum junction temperature limit.
Can PBSS4350D replace a standard SOT223 NPN transistor in existing PCB layouts?
No - PBSS4350D uses TSOP6 (SOT457), a 6-pin 3.0 mm × 2.5 mm package with different pin count, spacing, and thermal pad geometry versus SOT223's 3-pin 6.7 mm × 3.7 mm outline; redesign of solder mask, footprint, and routing is required to accommodate four collector terminals and base/emitter placement.
Is PBSS4350D suitable for linear regulator pass transistor applications?
No - PBSS4350D is optimized for saturated switching, not linear operation; its Safe Operating Area (SOA) is not characterized for DC linear mode, and continuous operation at VCE > 2 V risks thermal runaway due to lack of SOA derating curves and limited fT-driven stability margin in feedback loops.
What is the base-emitter leakage current specification at elevated temperature?
IEBO is specified at ≤100 nA at VEB = 5 V and Tamb = 25 °C; at Tj = 150 °C, leakage increases to ≤1 µA based on typical silicon behavior and Nexperia's characterization data - sufficient for most digital-switching applications but not precision analog biasing.
