BC818-40-TP

Overview

The BC818-40-TP is an NPN silicon bipolar junction transistor manufactured by Micro Commercial Components. It features a collector-emitter voltage of 45 V, a collector-base voltage of 50 V, and an emitter-base voltage of 5 V. The device supports a maximum continuous DC collector current of 500 mA with a power dissipation rating of 200 mW. Key electrical characteristics include a minimum DC current gain (hFE) of 100 at 1 V and 100 mA, and a transition frequency of 100 MHz. It operates within a temperature range of -55°C to +150°C and is housed in an SOT-323-3 surface-mount package.

Feature Summary

NPN silicon construction for reliable signal amplification
High DC current gain suitable for low-power switching applications
Automotive qualification compliant with AEC-Q101 standards

Applications

General-purpose signal amplification circuits
Low-power switching applications
Automotive electronic systems requiring AEC-Q101 compliance

Procurement Notes

Verify the specific datasheet version for the BC818-40-TP to confirm exact pinout configurations and thermal resistance values. Ensure that the ordering suffix matches the required packaging format, such as cut tape or reel, as these may affect handling procedures. Cross-reference the manufacturer's latest documentation to validate RoHS compliance status and any recent design changes before finalizing procurement specifications.

Selection Notes

Select this component when an NPN transistor with a 45 V collector-emitter voltage and 500 mA current capacity is required in a compact SOT-323-3 package. Consider its AEC-Q101 qualification if the application demands automotive-grade reliability. Compare its 200 mW power dissipation limit against the expected thermal load to ensure adequate heat management without additional cooling measures.

Part Context

This part belongs to the BC817/BC818 series of small-signal NPN transistors from Micro Commercial Components. While similar to the BC817-40 variant, the BC818-40-TP shares identical voltage ratings but may differ in specific gain binning or manufacturing lot characteristics. It serves as a standard discrete semiconductor solution for general electronics and automotive subsystems requiring robust NPN switching performance.
