Overview
The BC807-40CLT1 is a PNP silicon general-purpose transistor manufactured by onsemi. It operates with a maximum collector-emitter voltage of 45 V and supports a continuous collector current of 500 mA. The device is housed in an SOT-23 surface-mount package, which has the JEDEC designation TO-236AB. It features a power dissipation rating of 345 mW at ambient temperature. The component is designed for use in switching and amplification circuits.
Feature Summary
- High current capability suitable for demanding load applications
- Low saturation voltage for efficient switching performance
- Complementary to NPN BC817 series for push-pull configurations
Applications
- General-purpose switching circuits
- Amplifier stages
- Driver circuits for relays or LEDs
Procurement Notes
Verify the specific suffix CLT1 against official onsemi documentation to confirm tape-and-reel packaging and lead-free status. Ensure the ordering part number matches the exact voltage grade and gain bin required for the design. Cross-reference the manufacturer's latest datasheet for any updates regarding RoHS compliance or material declarations prior to procurement.
Selection Notes
Select this component when a compact PNP switch is needed with moderate current handling. It serves as the direct complement to the BC817-40 NPN transistor. Consider the thermal resistance and power derating curves if operating near the maximum limits. Verify that the SOT-23 footprint aligns with the PCB layout constraints.
Part Context
This part belongs to the BC807 family of small-signal PNP transistors. The family includes variants with different breakdown voltages, such as BC807-16 and BC807-25. The BC807-40 variant specifically offers a 45 V collector-emitter voltage rating. These devices are widely used in consumer electronics and industrial control systems due to their reliability and small form factor.
Replacement Considerations
Direct substitutes include the BC807-40 from other manufacturers like Nexperia or Diodes Inc., provided the pinout and electrical parameters match. Check for equivalent gain groups and thermal characteristics. Generic replacements must maintain the 45 V Vceo and 500 mA Ic ratings.
