PN3645 PBFREE

Single Bipolar Transistors Overview

The PN3645 PBFREE is a single PNP bipolar junction transistor (BJT) manufactured by Central Semiconductor Corp. It utilizes a TO-92 through-hole package and supports a maximum DC collector current of 800 mA with a continuous rating of 500 mA. The device withstands a collector-emitter voltage (VCEO) of 60 V and a collector-base voltage (VCBO) of 60 V, while maintaining an emitter-base voltage (VEBO) limit of 5 V. Key electrical characteristics include a power dissipation capacity of 625 mW, a gain-bandwidth product (fT) of 200 MHz, and a DC current gain (hFE) ranging from 80 to 240. The component operates within a temperature range of -65°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm lead-free status and plating type. Confirm that the TO-92 through-hole package matches the target PCB footprint requirements. Ensure the selected variant aligns with the required voltage and current ratings for the intended circuit design before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 60 V breakdown voltage and moderate current handling is required. The TO-92 package suits prototyping or low-volume through-hole designs. Verify that the 625 mW power dissipation limit accommodates the thermal environment. Consider the hFE range of 80 to 240 for biasing stability in analog applications.
