BC818-16-TP

Overview

The BC818-16-TP is a general-purpose NPN silicon transistor manufactured by Micro Commercial Components. It features a collector-emitter voltage rating of 50V and a continuous collector current capacity of 500mA. The device utilizes the Through Hole Plastic package type, specifically the SOT-23 form factor, designed for surface-mount applications. Key electrical parameters include a DC current gain (hFE) range of 100 to 200 at a collector current of 2mA, ensuring consistent amplification characteristics. The component operates within a junction temperature range of -55°C to +150°C and is rated for a maximum power dissipation of 350mW.

Feature Summary

• General-purpose NPN silicon construction suitable for amplifier and switching circuits
• High current capability with 500mA continuous collector current rating
• Wide operating temperature range extending up to 150°C junction temperature
• Surface-mount SOT-23 packaging for automated assembly compatibility

Applications

• General purpose switching applications
• Amplifier stages in audio and signal processing circuits
• Driver circuits for relays and LEDs
• Logic level translation interfaces

Procurement Notes

Verify the specific suffix 'TP' indicates the standard tape and reel or specific manufacturing batch configuration as defined by Micro Commercial Components datasheets. Confirm RoHS compliance status through official manufacturer documentation prior to integration into environmentally regulated assemblies. Ensure the ordering part number matches the exact pinout and thermal characteristics specified in the latest BC818-16 technical data sheet.

Selection Notes

Select this component when a compact NPN transistor with moderate current handling is required for surface-mount designs. The 50V breakdown voltage suits low-voltage logic systems. Compare hFE binning requirements against circuit sensitivity; the 100-200 gain range provides adequate margin for most digital switching tasks. Consider thermal management constraints given the 350mW dissipation limit in small packages.

Part Context

This transistor belongs to the BC818 series of general-purpose NPN devices widely used in consumer electronics and industrial control boards. The BC818-16 variant specifically denotes the 50V/500mA specification tier within the family. Micro Commercial Components produces this device to meet international quality standards for mass-market electronic assemblies.

Replacement Considerations

Direct substitutes include BC818-16 from other manufacturers such as Diodes Incorporated or ON Semiconductor, provided the SOT-23 footprint and electrical ratings match exactly. Verify pin alignment and thermal resistance values before substitution.
