Overview
The BC817-16 is a 45V NPN small signal transistor manufactured by Diodes Incorporated in an SOT23 package. It features a collector current of 0.5A and peak collector current of 1.0A. The DC current gain (hFE) ranges from 100 to 250 at IC=100mA, VCE=1V. Power dissipation is 310mW on FR-4 PCB and 350mW on copper pads. Thermal resistance junction-to-ambient is 403°C/W. Gain bandwidth product is 100MHz.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Qualified to AEC-Q101 standards for high reliability applications
- Totally lead-free and fully RoHS compliant with halogen and antimony free green device packaging
Applications
- General purpose switching circuits
- Audio frequency (AF) amplifier applications
Procurement Notes
Verify the specific ordering suffix '-7-F' matches the required reel size and tape width specifications. Confirm compliance requirements including AEC-Q101 qualification status and 'Green' material definitions against project constraints. Ensure the manufacturer marking code aligns with date code tracking needs for production batches.
Selection Notes
Select this component when a 45V NPN transistor with moderate current handling is required in a compact surface mount footprint. The BC817-16 variant offers a specific hFE range suitable for standard amplification tasks. Consider the complementary BC807 PNP type if push-pull configurations are needed within the same design architecture.
Part Context
This part belongs to the BC817 series of general-purpose NPN transistors alongside the -25 and -40 variants which differ primarily in DC current gain ranges. All share identical electrical ratings and physical dimensions but provide different gain bins to accommodate various circuit sensitivity requirements without changing the physical layout.
