Overview
The BC817-16WHE3-TP is a silicon NPN general-purpose bipolar junction transistor manufactured by Micro Commercial Components. It operates with a maximum collector-emitter voltage of 45 V and supports a continuous collector current of 500 mA. The device features a DC current gain (hFE) range of 100 to 250 at 100 mA, ensuring reliable amplification performance. Packaged in the compact SOT-23 surface-mount format, it offers a power dissipation capacity of 300 mW and meets AEC-Q101 automotive qualification standards for enhanced reliability.
Feature Summary
- Automotive-grade reliability certified under AEC-Q101 standards
- High current handling capability suitable for switching applications
- Compact SOT-23 package design optimized for space-constrained PCB layouts
Applications
- General-purpose signal amplification circuits
- Low-power electronic switching applications
- Automotive electronics requiring qualified components
Procurement Notes
Verify the specific suffix WHE3-TP against official MCC documentation to confirm RoHS compliance and lead-free status. Ensure the ordering quantity aligns with manufacturer reel specifications. Confirm that the intended application environment remains within the specified operating temperature range and power dissipation limits defined in the datasheet.
Selection Notes
Select this component when an NPN transistor with moderate current drive and high reliability is required. The BC817-16 variant provides a standardized gain band suitable for general logic interfacing. Consider the SOT-23 footprint constraints during layout planning. Verify thermal management requirements against the 300 mW dissipation limit for the chosen mounting configuration.
Part Context
This part belongs to the BC817 series of small-signal NPN transistors widely used in consumer and industrial electronics. The BC817-16 designation specifically indicates a DC current gain classification between 100 and 250. As an AEC-Q101 qualified device from MCC, it targets applications demanding higher durability than standard commercial grade parts.
Replacement Considerations
Compatible substitutes include BC817-16 from Nexperia or Diodes Incorporated. Verify pinout compatibility and electrical parameter equivalence before substitution.
