BCX38B PBFREE

Overview

The BCX38B PBFREE is a single NPN silicon planar epitaxial transistor manufactured by Central Semiconductor Corp. It is housed in an SOT-23 surface-mount package and designed for general-purpose switching and amplification applications. The device features a collector-emitter voltage rating of 60V, a collector current capacity of 0.8A, and a DC current gain (hFE) ranging from 100 to 400. It operates within a temperature range of -55°C to +150°C and complies with RoHS standards.

Feature Summary

• High DC current gain suitable for amplification tasks
• Surface-mount SOT-23 packaging for automated assembly
• Wide operating temperature range up to 150°C

Applications

• General-purpose signal amplification
• Low-power electronic switching circuits
• Driver stages in consumer electronics

Procurement Notes

Verify the specific suffix 'PBFREE' confirms lead-free compliance during procurement. Confirm the package type matches the design footprint requirements. Ensure the component meets the required thermal management specifications for the intended application environment.

Selection Notes

Select this component when a small-form-factor NPN transistor with moderate current handling is required. Consider the SOT-23 package constraints regarding thermal dissipation. Verify that the 60V breakdown voltage aligns with the circuit's maximum operating conditions.

Part Context

This part belongs to the BCX38 series of NPN transistors. It shares similar electrical characteristics with variants like BCX38A and BCX38C, differentiated primarily by their DC current gain bins. The series is commonly used in low-power analog and digital circuits requiring compact packaging solutions.

Replacement Considerations

Compatible substitutes include the BCX38A and BCX38C from the same manufacturer. Other generic SOT-23 NPN transistors with matching voltage and current ratings may serve as alternatives if pin compatibility is verified.
