The Central Semiconductor Corp BCX38B TIN/LEAD is a single NPN Darlington transistor designed for through-hole mounting in TO-92-3 packages. It features a collector-emitter voltage (VCEO) of 60 V, a collector-base voltage (VCBO) of 80 V, and an emitter-base voltage (VEBO) of 10 V. The device supports a maximum DC collector current of 800 mA with a power dissipation rating of 625 mW. Its gain-bandwidth product (fT) reaches 600 MHz, ensuring suitability for high-frequency signal amplification applications.
Verify the specific suffix 'TIN/LEAD' against official datasheets to confirm lead composition and RoHS status, as this variant differs from lead-free equivalents. Confirm package integrity upon receipt, as TO-92 components are sensitive to mechanical stress during handling and insertion into printed circuit boards.
Select this component when a high-current gain NPN transistor is required in a compact through-hole form factor. Ensure the application voltage does not exceed the 60 V collector-emitter limit. Consider thermal management requirements given the 625 mW power dissipation constraint in standard packaging configurations.
This part belongs to the BCX38 series of NPN Darlington transistors manufactured by Central Semiconductor. The series offers variations in voltage ratings and gain ranges, with the BCX38B specifically tailored for balanced performance between voltage handling and current drive capabilities in small-signal environments.
Official substitutes include the BCX38A and BCX38C variants within the same manufacturer series. Cross-manufacturer replacements must match the TO-92-3 package, NPN polarity, and comparable VCEO and IC specifications.
