BCW66F

Overview

The BCW66F is an SMD general-purpose NPN transistor manufactured by Diotec Semiconductor. It operates with a collector-emitter voltage of 45 V and a continuous DC collector current of 600 mA. The device dissipates up to 300 mW of power and functions within a junction temperature range of -55°C to +150°C. It utilizes the SOT-23 (TO-236) surface-mount package. Electrical characteristics include a minimum DC current gain of 110 at 10 mA and a maximum collector-base cutoff current of 20 µA at 125°C.

Feature Summary

• Low saturation voltage for efficient switching
• High collector current capability
• General-purpose design suitable for signal processing and amplification

Applications

• Signal processing

Procurement Notes

Verify the specific ordering suffix when purchasing, as it determines automotive compliance status. Standard commercial versions lack AEC-Q101 certification. Confirm RoHS and REACH compliance requirements match project specifications. Ensure the supplier provides official datasheets matching the exact part marking code '1P' to avoid counterfeit components.

Selection Notes

Select this component for standard commercial or industrial applications requiring reliable NPN switching. Use the -AQ suffix variant only if automotive qualification is explicitly required. Verify that the 600 mA current rating meets circuit demands. Consider thermal management for the 300 mW power dissipation limit in enclosed designs.

Part Context
