BC32725

Single Bipolar Transistors Overview

The Fairchild Semiconductor BC32725 is a PNP general-purpose bipolar junction transistor (BJT) designed for low-power switching and amplification applications. It features an 800 mA maximum collector current and a 45 V collector-emitter breakdown voltage. The device operates in a TO-92-3 through-hole package with a maximum power dissipation of 625 mW. Key electrical characteristics include a transition frequency of 100 MHz, a DC current gain (hFE) minimum of 160 at 100 mA, and a collector cutoff current of 100 nA. The component supports a maximum junction temperature of 150°C.

Single Bipolar Transistors Procurement Notes

Verify the manufacturer designation carefully, as onsemi has acquired Fairchild Semiconductor's discrete product line. Ensure the specific suffix matches the required binning or packaging configuration. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Check for obsolescence notices from original distributors.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with moderate current capability and standard voltage ratings is required. Compare hFE binning requirements against circuit design margins. Consider thermal management constraints due to the small TO-92 package size. Evaluate alternative packages if surface-mount technology is preferred for production.

Single Bipolar Transistors Part Context
