Overview
The BC817-40QAZ is a 45 V, 500 mA NPN general-purpose transistor manufactured by Nexperia. It utilizes the DFN1010D-3 (SOT1215) leadless ultra-small SMD plastic package with visible and solderable side pads. The device features a low profile of 0.37 mm height and offers two current gain selections. The BC817-40QA variant provides a DC current gain range of 250 to 600 at IC = 100 mA. It is qualified under AEC-Q101 standards for automotive applications.
Feature Summary
- AEC-Q101 qualified for automotive reliability
- Ultra-thin DFN1010D-3 package with solderable side pads
- Two distinct current gain selection options
Applications
- General-purpose switching
- Amplification circuits
- Mobile electronic devices
Procurement Notes
Verify the specific ordering suffix matches the required current gain bin and tape-and-reel configuration. Confirm that the DFN1010D-3 footprint aligns with the target PCB design constraints. Ensure compliance with automotive qualification requirements if deploying in vehicle systems. Cross-reference marking codes to validate authenticity upon receipt.
Selection Notes
Select this component when space-constrained designs require a leadless surface-mount solution. The low package height facilitates compact mobile electronics assembly. Choose the BC817-40QA variant specifically when higher DC current gain is necessary compared to lower gain alternatives within the same series.
Part Context
This part belongs to the BC817 family of NPN general-purpose transistors. It shares electrical characteristics with standard BC817 types but differs in physical packaging. The DFN1010D-3 package replaces traditional leaded formats to support miniaturization trends in modern consumer and automotive electronics manufacturing.
