Overview
The BC847BT TR PBFREE is an NPN small-signal bipolar junction transistor manufactured by Central Semiconductor Corp. It features a collector-emitter voltage rating of 45 V and a continuous collector current capacity of 100 mA. The device operates with a transition frequency of 300 MHz and a maximum power dissipation of 250 mW. DC current gain (hFE) is specified at a minimum of 200 when tested at 2 mA collector current and 5 V collector-emitter voltage. The saturation voltage is limited to 600 mV under conditions of 5 mA base current and 100 mA collector current. The component utilizes the SOT-23 surface-mount package and supports a junction temperature range from -55°C to 150°C.
Feature Summary
- Designed for general-purpose amplification and switching applications in low-power circuits.
- Optimized for automatic insertion processes due to its standard surface-mount packaging.
- Provides complementary pairing options within the BC857x series for push-pull configurations.
Applications
- General-purpose signal amplification
- Electronic switching circuits
- RF amplifier stages
Procurement Notes
Verify that the ordered part number matches the specific suffix requirements for the desired binning grade and packaging format. Confirm RoHS compliance status and check for any recent product change notices or end-of-life announcements from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a standard NPN transistor with 45 V breakdown and 100 mA current handling is required in a compact SOT-23 footprint. Ensure the application's power dissipation constraints remain within the 250 mW limit and that the required hFE gain meets the minimum threshold of 200 for the intended operating point.
Part Context
This part belongs to the BC847x series of NPN transistors, which are widely used in consumer electronics and industrial control systems. The 'BT' suffix typically denotes a specific gain binning and tape-and-reel packaging configuration. It serves as a common replacement for legacy through-hole devices in modern surface-mount designs requiring reliable small-signal performance.
Replacement Considerations
Direct substitutes include other manufacturers' BC847B variants in SOT-23 packages, such as those from Diotec or Diodes Incorporated, provided they meet the same electrical specifications and pinout compatibility.
