Product details
Overview
PBSS4330PA,115 from Nexperia is an NPN low VCEsat BISS transistor in a DFN2020-3 (SOT1061) leadless package, rated for 30 V VCEO, 3 A continuous collector current, and 75–100 mΩ RCEsat. It serves as a high-efficiency load switch in battery-powered power management circuits, delivering low conduction loss and compact PCB footprint.
For engineers reviewing the PBSS4330PA,115 datasheet, PBSS4330PA,115 pinout, PBSS4330PA,115 application, or PBSS4330PA,115 equivalent, key selection criteria include verified VCEsat ≤ 300 mV at 3 A/300 mA drive, thermal resistance as low as 60 K/W on ceramic PCB, and SOT1061 package compatibility with high-density reflow layouts.
Technical Context
This BISS transistor uses a breakthrough silicon structure optimized for ultra-low saturation voltage and high current gain (hFE = 180–310 at IC = 3 A), enabling efficient switching in medium-power DC loads without external base resistors in many configurations. Its exposed collector pad provides direct thermal and electrical path to PCB copper.
The device operates within −55 °C to 150 °C junction temperature range and supports pulsed peak currents up to 5 A (tp ≤ 1 ms). Switching performance includes ton = 63 ns and toff = 270 ns under standardized 9 V / 2 A test conditions, confirming suitability for high-frequency load control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 30 V - Maximum safe collector-emitter blocking voltage in open-base configuration; defines upper rail limit for load-switch applications. |
| IC | 3 A continuous - Rated DC collector current at Tamb ≤ 25 °C with standard FR4 mounting; enables direct driving of motors, fans, and charging paths. |
| RCEsat | 75–100 mΩ at IC = 3 A / IB = 300 mA - Low on-resistance minimizes I²R loss and self-heating during sustained conduction. |
| VCEsat | 220–300 mV at IC = 3 A / IB = 300 mA - Confirmed low saturation voltage ensures <0.3 V drop across switch, preserving battery voltage headroom. |
| hFE | 180–310 at VCE = 2 V, IC = 3 A - High DC current gain reduces required base drive current, easing MCU GPIO interface design. |
| toff | 270 ns - Fast turn-off time supports PWM frequencies >1 MHz in power management ICs and synchronous rectifier auxiliary switches. |
| Rth(j-a) | 60 K/W on Al2O3 ceramic PCB - Enables 2.1 W power dissipation at 25 °C ambient, critical for thermally constrained portable designs. |
Pinout & Package
DFN2020-3 (SOT1061) is an ultra-thin, leadless, thermally enhanced plastic package measuring 2.0 × 2.0 × 0.65 mm with an exposed collector pad on the bottom side for direct PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input node; requires ~300 mA drive for full saturation at 3 A load; compatible with 3.3 V/5 V logic-level sources. |
| 2 | Emiter (E) | Reference terminal for load return path; internally connected to substrate; must be tied to system ground or low-side reference. |
| 3 | Collector (C) | Main power output node; electrically and thermally connected to exposed bottom pad; routed to high-current load (e.g., motor, charger IC input). |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | 220–300 mV at 3 A ensures minimal voltage drop and <0.9 W conduction loss, extending battery runtime in portable devices. |
| Exposed collector pad | Direct thermal interface to PCB copper reduces Rth(j-a) to 60 K/W, allowing 2.1 W dissipation without heatsink on ceramic substrates. |
| High IC/ICM | 3 A continuous / 5 A pulsed rating supports demanding loads like brushless fan drivers and USB PD charging switches. |
| SOT1061 footprint | 2.0 × 2.0 mm body with no leads saves >50% board area vs. conventional SOT23, enabling ultra-compact power stage layouts. |
| BISS architecture | Breakthrough In Small Signal structure delivers higher hFE and lower RCEsat than standard BJT or MOSFET alternatives at same die size. |
Applications
| Load Switching | Battery Protection Circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low-VCEsat transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PBSS4350PA,115 | Higher VCEO = 50 V; identical SOT1061 package and RCEsat spec (75–100 mΩ) | Supports 48 V industrial bus rails; not optimized for <30 V battery systems where PBSS4330PA offers tighter VCEsat distribution | Select when system voltage exceeds 30 V but thermal and footprint constraints remain identical. |
| DMT3006LPSQ-13 | MOSFET (30 V, 6.5 A); gate-driven; RDS(on) = 28 mΩ @ VGS = 4.5 V; larger TSOP-6 package | Lower conduction loss at light loads; requires level-shifting for 1.8 V/3.3 V logic; no base current draw | Prefer for ultra-low static loss or logic-level gate drive; avoid if board space or base-drive simplicity is prioritized. |
Compared with PBSS4350PA,115, PBSS4330PA,115 offers tighter VCEsat tolerance at 30 V operation and lower cost in volume; versus DMT3006LPSQ-13, it eliminates gate drive complexity and reduces PCB area by 40%, though with higher conduction loss above 1 A.

FAQ
What is the maximum allowable base current for PBSS4330PA,115?
The absolute maximum base current is 500 mA, per the Limiting Values table. However, typical saturation drive uses 300 mA at IC = 3 A to achieve VCEsat ≤ 300 mV. Exceeding 500 mA risks permanent bond-wire damage, even briefly, and is not supported by thermal or reliability testing.
Can PBSS4330PA,115 be used in high-side switch configurations?
Yes - its 30 V VCEO rating and robust 3 A IC make it suitable for high-side switching when driven by a dedicated base driver (e.g., charge pump or level shifter) that supplies ≥1.2 V VBEsat and sufficient current. The exposed collector pad must connect directly to the load's positive rail.
How does thermal performance change with PCB copper area?
Rth(j-a) improves from 250 K/W (standard FR4 footprint) to 60 K/W (ceramic PCB with standard footprint) - a 4.2× reduction. On FR4, increasing collector pad area from 0 cm² to 6 cm² lowers Rth(j-a) from 250 to 100 K/W, enabling 1.25 W vs. 2.1 W dissipation at Tamb = 25 °C.
Is PBSS4330PA,115 automotive qualified?
No - this part is not AEC-Q101 qualified and lacks automotive-specific screening, qualification reports, or guaranteed PPAP documentation. Nexperia explicitly states non-automotive qualification in the Legal Information section; use only in industrial, consumer, or computing applications.
