Product details
Overview
PBSS4041SP from Nexperia is a dual PNP low VCEsat Breakthrough In Small Signal (BISS) transistor in SOT96-1 (SO8) package, designed for high-efficiency load switching with −60 V VCEO, −5.9 A continuous IC, and 47–70 mΩ RCEsat at −4 A/−400 mA drive-used in battery-powered power switches for motors and fans.
For engineers reviewing the PBSS4041SP datasheet, PBSS4041SP pinout, PBSS4041SP application, or PBSS4041SP equivalent, this device supports high-current, low-loss switching in compact PCB layouts where thermal performance and saturation voltage are critical selection criteria.
Technical Context
This dual PNP BISS transistor integrates two independent PNP transistors sharing a common collector terminal layout (pins 5–8), enabling synchronous or independent switching control per channel. Its low RCEsat and high hFE (120–180 at −4 A) reduce conduction losses and base drive requirements.
Thermal design leverages the SO8 package's dual-side copper mounting capability: Rth(j-a) ranges from 55 K/W (ceramic PCB) to 145 K/W (FR4 standard footprint), supporting sustained operation up to 150 °C junction temperature under defined PCB pad conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −60 V - Maximum blocking voltage before breakdown in load-switch applications requiring robust overvoltage margin. |
| IC | −5.9 A - Continuous collector current rating defining maximum steady-state load capacity per transistor. |
| RCEsat | 47–70 mΩ at IC = −4 A, IB = −400 mA - Directly determines on-state power loss (P = I² × R) and thermal rise in high-current switching. |
| hFE | 120–180 at IC = −4 A - Enables efficient base drive scaling; reduces required base current and driver circuit complexity. |
| toff | 515 ns - Fast turn-off time supports high-frequency PWM control in motor/fan drivers without excessive switching loss. |
| Ptot (per device) | 2.3 W on ceramic PCB - Defines maximum dissipated power before thermal derating; sets practical current limit under heatsink-limited conditions. |
Pinout & Package
SOT96-1 (SO8) is an 8-lead surface-mount plastic package with 3.9 mm body width, optimized for medium-power thermal dissipation via exposed collector pads (pins 5–8). Pin 1 is emitter of TR1; pin 4 is base of TR2; pins 5/6/7/8 are all collector terminals shared across both transistors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter TR1 | Current sink node for first PNP transistor; connects to load return path in high-side switch configuration. |
| 2 | Base TR1 | Control input for TR1; requires negative bias relative to emitter to enable conduction. |
| 3 | Emitter TR2 | Current sink node for second PNP transistor; enables dual-load or redundant switching paths. |
| 4 | Base TR2 | Independent control input for TR2; allows asynchronous or complementary drive schemes. |
| 5, 6, 7, 8 | Collector TR1/TR2 | Common high-side connection point; electrically tied internally-supports parallel current handling and enhanced thermal spreading. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | −190 to −275 mV at −4 A/−400 mA enables <100 mW conduction loss per transistor-critical for battery runtime extension. |
| Dual-transistor integration | Two matched PNP BISS devices in one SO8 package reduce board area by ~40% vs. discrete dual-SOT23 solutions. |
| High peak current | ICM = −15 A (1 ms pulse) supports motor startup surges and transient overload without latch-up or secondary breakdown. |
| Thermal robustness | Rth(j-sp) = 40 K/W to solder point ensures rapid heat transfer to PCB copper, enabling stable operation at 125 °C ambient. |
Applications
| Motor Control Switching | Battery Protection Circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT6009LSD-13 | N-channel dual MOSFET (60 V, 7.5 A); requires level-shifting gate drive for high-side use. | Better RDS(on) (12 mΩ) but adds external driver complexity and lacks integrated base control logic. | Select when ultra-low on-resistance justifies added gate-drive circuitry and layout space. |
| BC846BPDW1T1G | PNP/NPN dual small-signal transistor (65 V, 100 mA); no BISS architecture or power-rated RCEsat. | Only suitable for signal-level switching (<200 mA); cannot replace PBSS4041SP in >1 A load applications. | Use only for logic-level interface or bias networks-not for power switching functions. |
Compared with DMT6009LSD-13 and BC846BPDW1T1G, PBSS4041SP delivers integrated high-current PNP switching with minimal external components, lower system-level BOM count, and guaranteed −60 V/−5.9 A operation without gate-drive overhead or current-limiting compromises.

FAQ
What is the maximum safe operating temperature for PBSS4041SP?
The absolute maximum junction temperature is 150 °C, and storage temperature range is −65 °C to +150 °C. For continuous operation, ambient temperature must be limited to ensure junction temperature stays within this bound-derating curves show 2.3 W max power on ceramic PCB at 25 °C ambient, decreasing linearly above that.
Can PBSS4041SP be used in high-frequency PWM applications?
Yes-its 515 ns turn-off time and 110 MHz fT support PWM frequencies up to 100 kHz with minimal switching loss. However, optimal performance requires careful PCB layout: short base traces, low-inductance collector pads, and proper grounding to avoid oscillation during fast transitions.
How does the dual-collector pin configuration (pins 5–8) affect PCB layout?
All four collector pins (5, 6, 7, 8) are internally bonded together and must be connected to the same high-side net-typically a large copper pour for thermal spreading. This configuration improves current sharing and reduces effective thermal resistance by up to 30% compared to single-pin collector packages.
Is PBSS4041SP pin-compatible with any industry-standard dual-transistor packages?
No-it uses the proprietary SOT96-1 (SO8) footprint, which differs from standard SO8 IC packages and dual-SOT23 layouts. The 1.27 mm lead pitch and 3.9 mm body width require dedicated land patterns; migration from other dual-transistor packages necessitates PCB redesign and thermal validation.
