Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration before procurement. Confirm that the application environment does not require automotive qualification, as this specific part number is designated as non-automotive qualified. Ensure design safeguards are implemented to prevent operation beyond absolute maximum ratings.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring high-current PNP switching with minimal saturation voltage drop. The SOT223 package provides enhanced thermal dissipation compared to smaller surface-mount options. Verify that the -40 V voltage rating aligns with the circuit's maximum supply requirements and transient conditions.

Single Bipolar Transistors Part Context

Both devices share similar electrical characteristics and package dimensions, facilitating complementary push-pull or bridge configurations in power management circuits.

Single Bipolar Transistors Replacement Considerations

The PBSS4540Z serves as the direct NPN complement within the same product family. For equivalent PNP specifications in alternative packages, consult the broader PBSS series catalog. No other specific substitute part numbers are documented in the official datasheet.

Single Bipolar Transistors FAQ

Is the PBSS5540Z suitable for automotive applications?

No, the PBSS5540Z is not automotive qualified. It has not been tested according to automotive standards, and its use in automotive equipment is at the customer's risk.

What is the pin configuration for the SOT223 package?

Pin 1 is the Base, Pin 2 is the Collector, Pin 3 is the Emitter, and Pin 4 is also connected to the Collector.

How does mounting affect the thermal resistance?

In free air, the thermal resistance from junction to ambient is 92 K/W. When mounted on an FR4 PCB with a 6 cm² copper pad for the collector, it reduces to 62 K/W.
