Overview
The BCX71JT116 is a general-purpose amplification transistor manufactured by Rohm Semiconductor. It is housed in an SST3 package, which corresponds to the TO-236AB (SOT-23) surface-mount form factor with dimensions of 2.4x2.9 mm and a thickness of 1.2 mm. The device features three terminals and utilizes PNP polarity. Key electrical specifications include a collector power dissipation of 0.2 W, a collector-emitter voltage (Vceo1) of -45.0 V, and a collector current (Ic) of -0.2 A. The DC current gain (hfe) ranges from 140 to 630. It supports a storage temperature range from -55°C to 150°C.
Feature Summary
- Designed for general-purpose amplification applications
- Surface-mount construction compatible with automated assembly processes
- High DC current gain suitable for signal amplification tasks
Applications
- General-purpose signal amplification circuits
- Switching applications requiring low power dissipation
- Audio pre-amplifier stages
Procurement Notes
Verify the specific ordering suffix JT116 against official Rohm documentation to confirm tape-and-reel packaging details. Confirm RoHS compliance status as indicated in manufacturer records. Ensure the component meets the required hfe binning specifications for your circuit design before procurement.
Selection Notes
Select this component when a PNP transistor in a SOT-23 package is required for low-power amplification. Consider the -45 V collector-emitter voltage rating and 0.2 W power dissipation limits during thermal management planning. Verify that the 140 to 630 hfe range aligns with the gain requirements of the target application.
Part Context
This part belongs to Rohm's general-purpose transistor lineup. It is produced to support existing customers and is not recommended for new designs. Similar level replacements may exist within the same pinout and package family, such as the BC847 series, though polarity differences must be accounted for.
Replacement Considerations
The BC847BT116 is listed as a similar level replacement with the same pinout and package. Note that the BC847 is an NPN transistor, whereas the BCX71 is PNP; direct substitution requires circuit topology adjustment.
