Overview
The BCX56-TPQ4 is a PNP silicon small-signal bipolar junction transistor manufactured by Micro Commercial Components. It is housed in the SOT-323 surface-mount package, designated as SC-70 or SMT3. The device is rated for a continuous collector current of 1 A and a collector-emitter breakdown voltage of 60 V. It features a DC current gain (hFE) range of 80 to 800 at a collector current of -10 mA. The maximum power dissipation is specified at 300 mW when the ambient temperature is 25°C. The component operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- High current handling capability suitable for general-purpose switching applications
- Compact surface-mount footprint designed for automated assembly processes
- Wide current gain distribution supporting diverse amplification requirements
Applications
- General-purpose signal amplification circuits
- Low-power switching applications in consumer electronics
- Driver stages for relay or LED control modules
Procurement Notes
Verify the specific suffix 'Q4' against official Micro Commercial Components documentation to confirm tape-and-reel specifications and pinout orientation. Ensure the ordering part number matches the exact datasheet revision required for your design. Cross-reference with authorized distributors to confirm availability of the specific packaging format.
Selection Notes
Select this component when a compact PNP transistor with 1 A current capacity is required for space-constrained designs. Compare the SOT-323 package dimensions against board layout constraints. Evaluate the hFE spread to ensure compatibility with biasing networks in amplification circuits. Consider thermal management requirements given the low power dissipation rating of the small outline package.
