hFE of 200 minimum — why it matters for your BOM
The DC current gain is specified at a minimum of 200 at 2 mA collector current and 5 V Vce.
Package and footprint — SOT-23-3 (SST3)
The BC847BHZGT116 comes in a standard SOT-23-3 package, also referred to as TO-236-3 or SC-59, with the supplier device package code SST3. It is a surface-mount device, so it fits the usual SOT-23 footprint on your PCB. The maximum power dissipation is 200 mW — typical for this package size — so keep the junction temperature below 150°C (TJ) when you size the load and ambient conditions.
