BC81816MTF

Overview

The BC818-16MTF is an NPN general-purpose transistor manufactured by onsemi. It is housed in a compact SOT-323 surface-mount package. The device supports a collector-emitter voltage of 45 V and a continuous collector current of 500 mA. It features two specified DC current gain (hFE) ranges to accommodate different amplification requirements. The component is designed for high-current switching and linear amplification applications within small form-factor electronic circuits.

Feature Summary

• High current capability with 500 mA collector current rating
• Dual current gain selections for flexible circuit design
• Compact SOT-323 surface-mount package for space-constrained layouts

Applications

• General-purpose switching circuits
• Linear amplification stages
• Automotive board net applications

Procurement Notes

Verify the manufacturer marking and date code against official onsemi documentation to ensure authenticity. Confirm that the SOT-323 package variant matches the specific MTFA suffix requirements for your assembly process. Request RoHS compliance certificates and material declarations from authorized distributors prior to procurement.

Selection Notes

Select this component when a small footprint NPN transistor is required for moderate current switching or amplification. Compare the hFE binning options against the target circuit's base drive capabilities. Ensure the thermal management strategy aligns with the SOT-323 package's power dissipation limits under expected operating conditions.

Part Context

This part belongs to the BC818 series of NPN general-purpose transistors. It shares functional similarities with other members of the family, such as the BC817 and BC816 series, but utilizes the smaller SOT-323 package. The series is widely used in consumer electronics and automotive applications requiring reliable low-power switching performance.

Replacement Considerations

Direct substitutes include the BC818-16W from Nexperia, which offers identical electrical characteristics and pinout compatibility in the same SOT-323 package. Verify pin configuration and thermal resistance specifications before implementing any alternative sourcing.
