Overview
The BC816-25W-QX is an NPN general-purpose transistor manufactured by Nexperia, housed in a compact SOT323 (SC-70) surface-mount package. It supports a maximum collector current of 500 mA and withstands collector-emitter voltages up to 80 V. The device features a minimum DC current gain (hFE) of 250 and a transition frequency of 100 MHz. Power dissipation is rated at 200 mW, with an operating temperature range spanning from -55°C to +150°C. This component is qualified under the AEC-Q101 standard for automotive applications.
Feature Summary
- High voltage capability suitable for demanding switching environments
- Automotive reliability qualification ensuring robust performance
- Compact surface-mount design for space-constrained PCB layouts
Applications
- General-purpose switching circuits
- Signal amplification stages
- 48 V automotive board networks
Procurement Notes
Verify the specific suffix 'QX' against official Nexperia documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the selected variant matches the required AEC-Q101 automotive grade certification. Cross-reference the part number with authorized distributors to confirm availability and lead times prior to finalizing procurement plans.
Selection Notes
Select this component when high voltage tolerance and automotive reliability are required in a minimal footprint. The SOT323 package offers significant size reduction compared to traditional through-hole alternatives. Consider the 200 mW power dissipation limit during thermal analysis to ensure stable operation within the specified temperature range without derating.
Part Context
This part belongs to the BC816 series of NPN general-purpose transistors designed for modern electronic applications. The series provides multiple current gain options to accommodate various circuit requirements. The inclusion of the 'Q' designation indicates compliance with automotive quality standards, distinguishing it from standard commercial-grade variants within the same product family.
Replacement Considerations
Direct substitutes include other AEC-Q101 qualified NPN transistors in the SOT323 package with matching 80 V ratings and 500 mA current capabilities. Verify pinout compatibility and thermal characteristics before implementation.
