BCX19,215

Overview

The BCX19,215 is a single NPN silicon bipolar junction transistor manufactured by Nexperia. It utilizes Trench MOSFET technology principles adapted for BJT structures to achieve low saturation voltage and high current gain. The device is housed in a SOT-23 (TO-236AB) surface-mount plastic package with three pins. Key electrical ratings include a maximum collector-emitter voltage of 45 V, a maximum collector-base voltage of 50 V, and a maximum emitter-base voltage of 5 V. It supports a continuous DC collector current of 500 mA and has a power dissipation capability of 250 mW. The transition frequency is rated at 100 MHz, and the DC current gain (hFE) is specified as 100 at a collector current of 100 mA and Vce of 1 V.

Feature Summary

• Low saturation voltage for efficient switching performance
• High DC current gain suitable for amplification applications
• Robust thermal stability with extended operating temperature range

Applications

• General-purpose switching circuits
• Amplifier stages
• Driver circuits for loads requiring moderate current handling

Procurement Notes

Verify the specific ordering code suffix against official Nexperia documentation to ensure correct binning and packaging configuration. Confirm RoHS compliance status and lead times through authorized distributors. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering. Cross-reference pinout assignments with the latest datasheet revision to prevent integration errors during PCB assembly.

Selection Notes

Select this component when a compact NPN transistor with 500 mA current capacity and 45 V voltage rating is required. The SOT-23 package offers space efficiency for dense layouts. Consider the 100 MHz transition frequency for medium-speed signal processing. Evaluate thermal management needs given the 250 mW power dissipation limit in small packages. Compare hFE ranges if precise gain control is critical for the specific amplifier design.

Part Context

This part belongs to Nexperia's discrete bipolar transistor portfolio, designed for general electronic applications. The BCX series typically targets cost-sensitive consumer and industrial electronics where reliable switching and amplification are needed. The 215 suffix indicates standard tape-and-reel packaging for automated assembly processes.

Replacement Considerations

Consult official Nexperia substitution guides for verified equivalents. Generic replacements may differ in hFE binning or saturation voltage characteristics. Verify pin compatibility and thermal resistance values before swapping.
