2SB880

Single Bipolar Transistors Overview

The onsemi 2SB880 is a PNP bipolar junction transistor (BJT) designed for general-purpose switching applications. It utilizes silicon planar technology and is housed in the SOT-323 surface-mount package, which provides a compact footprint suitable for space-constrained designs. The device features a collector-emitter voltage rating of -50 V and a continuous collector current capacity of -1 A. Key electrical characteristics include a high DC current gain (hFE) ranging from 100 to 600 under specified conditions, ensuring efficient drive requirements. The component operates within a commercial temperature range and supports a maximum power dissipation of 300 mW at 25°C ambient temperature.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix to confirm the exact tape-and-reel quantity and packaging variant, as these details define the physical delivery format rather than the semiconductor function. Ensure the requested part number matches the required RoHS compliance status and lead time expectations directly stated by the manufacturer or authorized distributor for the specific batch.

Single Bipolar Transistors Selection Notes

Select this component when a small-form-factor PNP transistor is required for low-to-medium current switching tasks. The SOT-323 package offers a balance between thermal performance and board space efficiency. Consider the hFE spread when designing bias networks to ensure consistent performance across different units. Verify that the -50V voltage rating meets the circuit's peak reverse voltage requirements.

Single Bipolar Transistors Part Context

The 2SB880 belongs to the family of small-signal PNP transistors manufactured by onsemi. These devices are engineered for reliability in consumer electronics and industrial control systems where miniaturization is critical. The SOT-323 form factor is widely adopted in portable devices and dense PCB layouts, distinguishing it from larger through-hole alternatives while maintaining comparable electrical performance for standard switching duties.

Single Bipolar Transistors Replacement Considerations

Cross-reference with other SOT-323 PNP transitors such as the BC847 series (PNP equivalent BC857) or SS8550 equivalents if pin-compatible replacements are needed. Verify that substitute parts meet the same -50V VCEO and -1A IC ratings. Check for identical pinout configurations to ensure direct interchangeability without circuit modification.
