BC857BWT1G Description

Short technical summary and product information.

The BC857BWT1G is a PNP silicon general purpose transistor from On Semiconductor, designed for low-power surface-mount amplification and switching applications. It is housed in the compact SC-70/SOT-323 package (SC-70-3 case style), making it suitable for space-constrained designs.

 

Key electrical ratings include a maximum collector-emitter voltage (VCEO) of -45 V, collector-base voltage (VCBO) of -50 V, and continuous collector current of -100 mA (peak -130 mA for 1 ms pulse). The DC current gain (hFE) at Ic = -2 mA, Vce = -5 V is typically 290, with a range of 220 to 520 for the BC857B variant. Transition frequency is 100 MHz. Typical Vce saturation is -0.3 V at Ib = -0.5 mA, Ic = -10 mA.

 

The device is rated for an operating temperature range of -55°C to +150°C, with a maximum power dissipation of 150 mW on an FR-5 board at 25°C. It is Pb-Free, Halogen Free/BFR Free, and RoHS compliant as per the datasheet.
