BC394 TIN/LEAD

Single Bipolar Transistors Overview

The BC394 is a silicon planar epitaxial PNP transistor manufactured by Central Semiconductor Corp. It features a hermetically sealed metal can package with tin/lead terminations, designed for high-reliability applications. The device operates as a general-purpose amplifier or switch with a collector-emitter voltage rating of 60V and a continuous collector current capacity of 1A. Key electrical parameters include a DC current gain (hFE) ranging from 70 to 700 at IC=10mA, and a transition frequency (fT) of 250MHz at IC=10mA. The component supports a maximum power dissipation of 800mW at 25°C ambient temperature.

Single Bipolar Transistors Procurement Notes

Verify the specific termination material matches the required tin/lead specification, as lead-free variants may exist under different suffixes. Confirm the package style corresponds to the standard metal can format. Ensure the supplier provides traceability documentation for hermetically sealed components intended for critical applications. Check for any environmental compliance declarations if the end-use requires specific regulatory adherence beyond the base component specifications.

Single Bipolar Transistors Selection Notes

Select this component when high reliability and hermetic sealing are required for PNP transistor applications. Consider the 60V collector-emitter voltage and 1A current ratings against circuit demands. Evaluate the hFE range of 70-700 for biasing requirements. Compare thermal resistance values if operating near the 800mW power dissipation limit. Ensure the metal can package fits within the mechanical constraints of the target assembly.

Single Bipolar Transistors Part Context

The BC394 belongs to Central Semiconductor's lineup of hermetically sealed discrete semiconductors. These components are engineered for defense, aerospace, and medical markets where failure is not an option. The tin/lead variant represents traditional termination options before widespread RoHS mandates. This part complements other NPN/PNP pairs in the manufacturer's catalog for complementary symmetry designs.

Single Bipolar Transistors Replacement Considerations

Direct replacements must match the PNP type, hermetic metal can package, and similar electrical ratings. Verify pinout compatibility to avoid circuit damage during substitution. Consider thermal performance differences if the alternative uses a different substrate or sealant material. Ensure the replacement maintains the required radiation hardness or vacuum compatibility if applicable.
