Product details
Overview
PBSS4350D from Nexperia is a 50 V, low VCEsat NPN transistor in TSOP6 (SOT457) package, rated for 3 A continuous collector current and 5 A peak pulse current, with typical RCEsat 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 290 mV max VCEsat under pulsed 2 A load conditions.
Technical Context
This NPN transistor operates as a high-efficiency saturated switch with guaranteed VCEsat ≤ 290 mV at IC = 2 A and IB = 200 mA, supported by hFE ≥ 100 under same conditions. Its 50 V VCEO rating and 60 V VCBO enable robust operation in 24–48 V industrial supply rails.
AEC-Q101 qualification confirms suitability for automotive-grade line switching, while the TSOP6 package provides six terminals-four collector leads, one base, and one emitter-for low-inductance, high-current PCB routing and thermal spreading across multiple copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit for switching in 24 V and 48 V systems. |
| IC (continuous) | 3 A - Sustained collector current capability; enables direct drive of small motors or lamps without external heatsinking on 6 cm² copper. |
| RCEsat | 110–145 mΩ - On-resistance range at IC = 2 A / IB = 200 mA; determines conduction loss and junction temperature rise under load. |
| VCEsat (max) | 290 mV - Worst-case saturation voltage; sets minimum power dissipation (≤ 580 mW) during full-load switching. |
| hFE | ≥ 100 - Minimum DC current gain at IC = 2 A; ensures reliable saturation with ≤ 20 mA base drive per 2 A collector current. |
| Tj (max) | 150 °C - Absolute maximum junction temperature; allows operation in under-hood automotive environments with proper PCB thermal design. |
Pinout & Package
TSOP6 (SOT457) plastic surface-mount package with 6 leads, 3.0 mm × 2.5 mm footprint, and exposed collector thermal pad. Four collector pins (1, 2, 5, 6) provide parallel current paths and enhanced thermal conduction to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Collector | Primary current-carrying terminal tied internally to die substrate; connected to large copper pour for heat dissipation. |
| 2 | Collector | Redundant collector connection; reduces bond wire inductance and improves current sharing in high-frequency switching. |
| 3 | Base | Control input requiring ~200 mA pulsed drive for full saturation; routed away from high-current paths to minimize coupling. |
| 4 | Emiter | Reference node for load return path; placed adjacent to base for tight layout of driver circuitry. |
| 5 | Collector | Third collector terminal enabling symmetrical PCB layout and balanced thermal distribution across package body. |
| 6 | Collector | Fourth collector terminal supporting >3 A continuous operation with <160 K/W Rth(j-a) on 6 cm² copper. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | 290 mV max ensures ≤ 580 mW conduction loss at 2 A, reducing thermal stress in compact battery-powered designs. |
| AEC-Q101 qualified | Validated for automotive temperature cycling, humidity, and mechanical shock-enables use in engine bay and ADAS power stages. |
| Multi-collector TSOP6 | Four collector pins lower effective package resistance and improve thermal transfer, enabling higher sustained current than SOT223/SOT89. |
| High ICM | 5 A peak pulse rating supports inrush current handling in motor start-up and strobe flash discharge circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low VCEsat NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40501MR6T1G | 40 V VCEO, 4.5 A IC, 120 mΩ RCEsat, SOT-23-6 package with only two collector pins. | Limited to ≤ 36 V systems; lower thermal mass and single-sided copper requirement restricts sustained >2 A operation. | Select when board space is constrained and peak current < 3 A; avoid in automotive under-hood locations due to non-AEC-Q101 status. |
| Diodes Incorporated DXTN3C45PS6-13 | 45 V VCEO, 3 A IC, 135 mΩ RCEsat, TSOP6 package but not AEC-Q101 qualified. | Acceptable for industrial DC/DC converters but lacks automotive stress validation for vibration, temperature cycling, and ESD robustness. | Prefer for cost-sensitive non-automotive applications where AEC-Q101 is not mandated; verify thermal performance on 6 cm² copper separately. |
Compared with NSS40501MR6T1G and DXTN3C45PS6-13, PBSS4350D delivers superior automotive compliance, higher voltage margin (50 V vs. 40–45 V), and four-collector thermal architecture-making it the only choice for AEC-Q101–required 24 V/48 V line switching with >2 A continuous demand.

FAQ
What is the maximum continuous collector current for PBSS4350D at 25 °C ambient?
The PBSS4350D supports 3 A continuous collector current (IC) at Tamb ≤ 25 °C when mounted on an FR4 PCB with 6 cm² single-sided copper pad. Derating applies above 25 °C per the thermal resistance curve in Table 6, with full derating to zero at 150 °C junction temperature.
Is PBSS4350D suitable for automotive under-hood applications?
Yes-PBSS4350D is fully AEC-Q101 qualified per the November 2023 datasheet, including stress testing for temperature cycling, humidity, mechanical shock, and ESD. Its 150 °C maximum junction temperature and validated performance from −55 °C to +150 °C make it appropriate for under-hood power switching.
How many collector terminals does PBSS4350D have, and why?
PBSS4350D has four collector terminals (pins 1, 2, 5, and 6) in its TSOP6 package. This multi-terminal configuration lowers effective package resistance, improves current sharing, and enhances thermal conduction to the PCB-enabling higher sustained current and lower Rth(j-a) than conventional 3-pin packages.
What is the typical base-emitter saturation voltage at full load?
At IC = 2 A and IB = 200 mA (10:1 drive ratio), VBEsat is typically 1.2 V, with a maximum of 1.2 V specified in Table 7. This value remains stable across −55 °C to +150 °C, ensuring predictable base drive requirements in wide-temperature applications.
