Overview
The BCW72T116 is a single NPN bipolar junction transistor manufactured by Rohm Semiconductor. It utilizes the SST3 surface-mount package, which corresponds to the SOT-23 form factor with dimensions of 2.4x2.9 mm and a thickness of 1.2 mm. The device features three terminals and supports a collector-emitter voltage (Vceo) of 45 V. It is rated for a continuous collector current of 100 mA and a maximum power dissipation of 0.2 W. The component operates within a storage temperature range of -55°C to 150°C.
Feature Summary
- NPN polarity configuration for signal amplification
- SST3 surface-mount packaging for automated assembly
- 45 V collector-emitter voltage rating
- 0.2 W power dissipation capability
Applications
- General purpose signal amplification
- Switching applications in low-power circuits
- Small-signal processing stages
Procurement Notes
Verify the supply status before integration, as this component may be classified as Not Recommended for New Designs (NRND). Confirm that the SST3 package dimensions align with existing PCB footprints. Ensure compliance with RoHS standards if required by the target application environment. Check for active alternatives if long-term availability is critical for the product lifecycle.
Selection Notes
Select this component when a small-signal NPN transistor with a 45 V breakdown voltage is required in an SST3 package. The 100 mA current rating suits low-power switching tasks. Consider thermal management due to the 0.2 W dissipation limit. Verify that the hFE gain characteristics meet the specific circuit requirements for amplification or switching speed.
Part Context
The BCW72T116 belongs to Rohm Semiconductor's line of single bipolar transistors designed for surface-mount technology. It serves as a compact solution for consumer electronics and industrial control boards where space constraints necessitate the use of SOT-23 style packages. The part is distinct from higher-power variants and focuses on low-current signal handling.
Replacement Considerations
The BC847C is documented as a similar level replacement with the same pinout and package. Verify electrical parameter compatibility, particularly regarding collector current and gain ranges, before substituting.
