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 pulse current, 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 verified AEC-Q101 qualification, thermal resistance of 160 K/W on 6 cm² copper pad, and confirmed 6-pin TSOP6 layout with 4 collector terminals for enhanced current handling and thermal dissipation.
Technical Context
This NPN transistor employs a low-saturation-voltage silicon epitaxial planar structure optimized for high-current switching with minimal conduction loss. Its design integrates four parallel collector terminals to reduce bond-wire resistance and improve thermal spreading across the die attach area.
It operates with a minimum DC current gain (hFE) of 100 at IC = 2 A and VCE = 2 V under pulsed conditions, and delivers VCE(sat) ≤ 290 mV at IC = 2 A / IB = 200 mA, enabling efficient operation in high-duty-cycle load-switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum allowable collector-emitter voltage with base open; defines safe blocking capability in supply-line switching. |
| IC | 3 A - Continuous DC collector current rating; sets maximum steady-state load drive capacity. |
| RCE(sat) | 110–145 mΩ - On-resistance at IC = 2 A / IB = 200 mA; directly determines conduction loss and self-heating in power stage. |
| hFE | 100 min - Minimum DC current gain at IC = 2 A; ensures reliable saturation with practical base drive levels. |
| Ptot | 750 mW - Total power dissipation on 6 cm² FR4 copper pad; defines thermal limit under sustained operation. |
| AEC-Q101 | Qualified - Validated per Automotive Electronics Council stress test standard; supports automotive-grade reliability requirements. |
Pinout & Package
Package: TSOP6 (SOT457), surface-mount plastic package with 6 leads, 3.0 mm × 2.5 mm footprint, 1.3 mm height, and integrated heat-spreading collector pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Collector | Primary current-carrying terminal; electrically and thermally connected to internal die and exposed pad. |
| 2 | Collector | Redundant collector connection; lowers effective RDS(on)-equivalent and improves thermal path symmetry. |
| 3 | Base | Control input for transistor turn-on; requires ≥200 mA drive for full saturation at 2 A load. |
| 4 | Emiter | Reference node for emitter-follower or common-emitter configurations; tied to system ground or return path. |
| 5 | Collector | Third collector terminal; shares current with pins 1 and 2 to distribute bond-wire stress and thermal load. |
| 6 | Collector | Fourth collector terminal; enables uniform current sharing and reduces localized heating in high-pulse applications. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | ≤290 mV at IC = 2 A - Reduces power loss by >40% vs. standard SOT223 transistors in same bias condition. |
| Multi-collector architecture | 4 collector terminals - Enables 3 A continuous current with <1.5°C/W junction-to-board thermal resistance on 6 cm² copper. |
| AEC-Q101 qualification | Automotive-grade reliability - Validated for temperature cycling, HTRB, and ESD per AEC-Q101 Rev G. |
| Thermal enhancement | Rth(j-a) = 160 K/W - Achieved via extended collector pad area and optimized leadframe plating for solder wetting. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-VCE(sat) NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40501MUTBG | Same TSOP6 package, but lower IC (2 A) and higher RCE(sat) (180 mΩ typ); no AEC-Q101 qualification. | Suitable for consumer-grade DC/DC converters where automotive qualification is not required. | Select when cost sensitivity outweighs automotive compliance and thermal performance needs. |
| Diodes Incorporated DXTN200100000000 | Higher VCEO (60 V), but larger SOT-23-6 package and 220 mΩ RCE(sat); AEC-Q101 qualified. | Better suited for 48 V industrial power rails where voltage margin is critical over thermal density. | Prefer when system voltage exceeds 45 V and board space allows larger footprint. |
Compared with NSS40501MUTBG and DXTN200100000000, PBSS4350D uniquely balances 3 A continuous current, 110 mΩ RCE(sat), AEC-Q101 qualification, and compact TSOP6 packaging-making it optimal for space-constrained, thermally demanding automotive battery switches.

FAQ
What is the maximum continuous collector current for PBSS4350D?
The PBSS4350D is rated for 3 A continuous collector current (IC) at Tamb ≤ 25 °C with a 6 cm² copper pad. Derating applies above 25 °C ambient, reaching zero current at 150 °C junction temperature. This rating assumes proper PCB thermal design per Figure 9 in the datasheet.
Is PBSS4350D pin-compatible with standard SOT223 transistors?
No-PBSS4350D uses the 6-pin TSOP6 (SOT457) package with four collector terminals, unlike the 3-pin SOT223. It is not mechanically or electrically pin-compatible, though it serves as a functional upgrade in thermal and electrical performance for similar applications.
Does PBSS4350D require a heatsink in typical applications?
Not typically-its Rth(j-a) is 160 K/W on a 6 cm² FR4 copper pad, allowing 3 A operation at 25 °C ambient without an external heatsink. For sustained 3 A loads above 50 °C ambient or pulsed 5 A operation, additional copper area or forced airflow is recommended.
How does the multi-collector configuration affect PCB layout?
The four collector pins (1, 2, 5, 6) must be routed to a common large copper pour for optimal current sharing and thermal spreading. Splitting collectors or routing them separately increases resistance imbalance and localized heating, degrading RCE(sat) and reliability.
