Overview
The Nexperia BC816-25WX is an NPN general-purpose transistor housed in a SOT323 (SC-70) surface-mount package. It supports a collector-emitter voltage of 80 V and a continuous collector current of 500 mA, with a peak pulse current capability of 1 A. The device offers two DC current gain selections; the -25 variant provides a minimum hFE of 160 at IC = 100 mA and VCE = 1 V. Total power dissipation is rated at 200 mW at 25 °C ambient temperature. The component is qualified to AEC-Q101 standards for automotive reliability.
Feature Summary
- High voltage rating of 80 V suitable for demanding switching environments
- AEC-Q101 qualification ensuring suitability for automotive applications
- Two distinct current gain selections available within the series
Applications
- General-purpose switching circuits
- Amplification tasks
- 48 V automotive board net systems
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm exact packaging and reel specifications. Confirm that the delivered components match the required AEC-Q101 automotive grade status. Ensure the marking code corresponds to the BC816-25W designation before integration into production lines.
Selection Notes
Select this component when an 80 V breakdown voltage exceeds standard 45 V requirements. Choose the -25 suffix specifically for applications requiring a higher minimum DC current gain compared to the -16 variant. Verify thermal management capabilities align with the 200 mW power dissipation limit under expected operating conditions.
Part Context
This part belongs to the BC816W series of NPN transistors designed for compact surface-mount implementations. It serves as the complement to the BC806-25W PNP device. The series is engineered to provide high current handling within the small SC-70 footprint, addressing space constraints in modern electronic designs.
Replacement Considerations
BC816-16W: Offers lower minimum current gain but shares identical voltage and current ratings.
FAQ
What is the maximum peak collector current for single pulses?
The maximum peak collector current is 1 A for single pulses with a duration of tp ≤ 1 ms.
How does the BC816-25W differ from the BC816-16W?
The primary difference is the DC current gain range; the BC816-25W has a minimum hFE of 160, whereas the BC816-16W has a minimum hFE of 100.
Is this component suitable for automotive use?
Yes, the product is qualified in accordance with the AEC-Q101 standard for discrete semiconductors.
