Overview
The BC817K-16-TP is an NPN silicon general-purpose transistor manufactured by Micro Commercial Components (MCC). It belongs to the BC817 series and features a SOT-23 surface-mount package. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 45 V, a continuous collector current (IC) of 500 mA, and a DC current gain (hFE) range of 100 to 250 at 100 mA. The device has a power dissipation rating of 300 mW and operates within a temperature range of -55°C to +150°C.
Feature Summary
- Designed for general audio frequency (AF) applications
- High collector current capability
- Low collector-emitter saturation voltage
Applications
- General audio amplification circuits
- Switching applications
- Driver stages in electronic systems
Procurement Notes
Verify the specific suffix 'K' indicates the hFE binning range (100-250) compared to standard variants. Confirm the 'TP' designation aligns with MCC's standard tape-and-reel packaging requirements. Ensure the SOT-23 footprint matches the target PCB layout. Cross-reference the datasheet revision date to confirm compliance with current RoHS standards.
Selection Notes
Select this component when a moderate current gain (100-250) is required for signal amplification or switching. It serves as a direct replacement for other manufacturers' BC817-16 equivalents. Consider the 300 mW power limit for thermal management in dense layouts. Verify compatibility with complementary PNP types like the BC807 series if push-pull configurations are needed.
Part Context
This part is part of the broader BC817 family of NPN silicon transistors produced by multiple vendors including Infineon and NXP. The 'K' suffix typically denotes a specific current gain bin. The BC817 series is widely used in consumer electronics and industrial control due to its small form factor and reliable performance in low-power analog and digital switching roles.
Replacement Considerations
Direct substitutes include BC817-16 from other manufacturers such as Nexperia or Diodes Incorporated. Ensure the replacement maintains the same SOT-23 package and hFE binning specifications to guarantee circuit performance consistency.
