BCX17,215

Overview

The BCX17,215 is a silicon NPN bipolar junction transistor manufactured by Nexperia. It is housed in the SOT-23 surface-mount package with three terminals. The device supports a maximum continuous collector current of 800 mA and withstands a collector-emitter voltage of 45 V. Key electrical characteristics include a collector-base breakdown voltage of 60 V and an emitter-base breakdown voltage of 5 V. The component features a minimum DC current gain (hFE) of 100 at specified test conditions and a transition frequency of 100 MHz. It operates within a temperature range of -65°C to +150°C and has a power dissipation rating of 250 mW.

Feature Summary

• High current handling capability suitable for switching applications
• Automotive qualification compliant with AEC-Q101 standards
• Compact SOT-23 surface-mount packaging for space-constrained designs

Applications

• General-purpose switching circuits
• Automotive electronics systems
• Signal amplification stages

Procurement Notes

Verify the specific hFE binning classification required for your design, as the BCX17 series often includes suffixes indicating different gain ranges. Confirm that the SOT-23 thermal resistance values meet your system's heat dissipation requirements under maximum load conditions. Ensure compliance with RoHS directives if applicable to your manufacturing region.

Selection Notes

Select this component when a robust NPN transistor with 800 mA current capacity is needed in a small footprint. Compare against the BCX16 or BCX18 variants if different current gain thresholds are necessary. Consider the 45 V voltage rating to ensure adequate headroom for your circuit's operating voltage.

Part Context

This part belongs to the BCX17 series of general-purpose NPN transistors from Nexperia. These devices are widely used in consumer and industrial electronics due to their balance of performance and cost. The BCX17 specifically targets applications requiring moderate power handling in compact surface-mount formats.

Replacement Considerations

Check datasheets for alternative parts like the BCX16 or BCX18 to verify pin compatibility and electrical parameter alignment before substitution.
