Overview
The BC817-16,215 is an NPN general-purpose transistor manufactured by Nexperia. It operates with a collector-emitter voltage of 45 V and a continuous collector current of 500 mA. The device supports a peak single-pulse collector current of 1 A. DC current gain (hFE) ranges from 100 to 250 at IC = 100 mA and VCE = 1 V. Transition frequency is 100 MHz. Total power dissipation is 250 mW at Tamb ≤ 25 °C. Junction temperature reaches 150 °C. Storage temperature spans -65 °C to 150 °C. Thermal resistance junction-to-ambient is 500 K/W in free air. Package is SOT23 (TO-236AB).
Feature Summary
- High current capability for general switching applications.
- Defined current gain selection for predictable amplification performance.
Applications
- General-purpose switching circuits
- Signal amplification stages
Procurement Notes
Verify the specific ordering code matches the required hFE binning. Confirm package type corresponds to SOT23. Check datasheet revision status against production requirements. Ensure application conditions remain within absolute maximum ratings. Validate thermal management design for the target ambient temperature.
Selection Notes
Select this component when a low-voltage NPN switch or amplifier is needed in a compact surface-mount footprint. The BC817-16 variant provides a specific gain range suitable for standard logic interfacing. Compare total power dissipation limits against expected load currents. Evaluate thermal resistance values for PCB mounting constraints.
Part Context
This part belongs to the BC817 series of NPN transistors. The series includes variants with different gain ranges: BC817, BC817-25, and BC817-40. All share identical electrical limits and physical dimensions. The PNP complement is the BC807 series. The BC817-16 specifically targets applications requiring moderate gain consistency.
Replacement Considerations
BC817-25,215 offers higher gain (160-400). BC817-40,215 provides even higher gain (250-600). BC817,215 covers the full range (100-600). BC807-16,215 is the PNP equivalent. Verify pinout compatibility across all SOT23 packages before substitution.
FAQ
What is the marking code for the BC817-16?
The marking code is 6A followed by a manufacturing site code placeholder.
Is the BC817-16 automotive qualified?
No, the product data sheet indicates it is not automotive qualified. Automotive alternatives are available separately.
What is the collector-base breakdown voltage?
The collector-base breakdown voltage is 50 V with the emitter open.
