BC818-40

Overview

The Diotec Semiconductor BC818-40 is a surface-mount NPN general-purpose bipolar junction transistor housed in an SOT-23 (TO-236) package. It features a collector-emitter voltage of 25 V and a continuous collector current of 800 mA. The device offers three DC current gain groups: Group -16, Group -25, and Group -40. Maximum power dissipation is rated at 300 mW when mounted on a printed circuit board with 3 mm² copper pads. The transition frequency is typically 100 MHz.

Feature Summary

General-purpose switching and amplification capabilities
Three distinct DC current gain groupings for design flexibility
Compliant with RoHS, REACH, and Conflict Minerals regulations

Applications

Signal processing circuits
Electronic switching applications
Amplification stages

Procurement Notes

Verify the specific suffix to confirm the operating grade. Standard versions without suffixes are industrial grade. Versions with the -C suffix are commercial grade. Automotive-grade options include -Q for AEC-Q101 compliance and -AQ for AEC-Q101 qualification. Confirm these markings match project requirements before procurement.

Selection Notes

Select this component for standard commercial or industrial applications requiring high current handling in a small footprint. Ensure the chosen current gain group aligns with the required base drive conditions. Verify that the 25 V collector-emitter rating meets the circuit's maximum voltage stress limits under all operating conditions.

Part Context

This part belongs to the BC817/BC818 family of SMD general-purpose NPN transistors. The BC818 variant specifically provides lower voltage ratings compared to the BC817 series. The complementary PNP transistor for this device is the BC808.
