Overview
The BC818K16WE6327HTSA1 is an NPN silicon audio frequency transistor from the BC818K series, manufactured by Infineon Technologies. It features a collector-emitter voltage of 25 V and a continuous collector current of 500 mA. The device provides a DC current gain (hFE) group 16 with a minimum value of 100 at IC = 100 mA and VCE = 1 V. It operates within a junction temperature range of -65 °C to +150 °C and is housed in a SOT-323 package.
Feature Summary
- Designed for general audio frequency applications
- High collector current capability
- Low collector-emitter saturation voltage
- Qualified according to AEC-Q101 standards
Applications
- General audio frequency amplification circuits
- Switching applications requiring low saturation voltage
- Consumer electronics signal processing
Procurement Notes
Verify the specific hFE binning group required for the application, as the datasheet defines multiple gain groups (16, 25, 40). Confirm the package type matches the design, as the suffix 'W' indicates the SOT-323 variant. Ensure compliance with AEC-Q101 requirements if automotive qualification is necessary for the system.
Selection Notes
Select this component when a low-voltage NPN transistor with moderate current handling is needed for audio or switching tasks. Compare the hFE group 16 specifications against circuit bias requirements. Consider the thermal resistance characteristics for power dissipation limits in the SOT-323 package relative to ambient conditions.
Part Context
This part belongs to the BC817K/BC818K family of NPN silicon transistors. The BC818 variant specifically offers a lower collector-emitter voltage rating compared to the BC817. The 'W' suffix denotes the SOT-323 surface-mount package, while the 'E6327HTSA1' suffix identifies the specific tape-and-reel packaging and manufacturing lot details.
Replacement Considerations
Direct substitutes include other BC818K variants with different hFE bins, such as BC818K25 or BC818K40, provided the gain requirements are met. Cross-reference with generic SOT-323 NPN transistors having similar VCEO and IC ratings, ensuring pinout compatibility.
