BC857BLT1 Description

Short technical summary and product information.

The BC857BLT1 is a PNP silicon general purpose transistor from ON Semiconductor. It features a minimum collector-emitter breakdown voltage of -45V, a collector-base breakdown voltage of -50V, and an emitter-base breakdown voltage of -5V. The continuous collector current is rated at -100mA with a peak current of -200mA. Power dissipation is 225mW on an FR-5 board and 300mW on an alumina substrate at 25°C ambient temperature, with derating above 25°C. Thermal resistance is 556°C/W on FR-5 and 417°C/W on alumina. The junction temperature range is -55°C to 150°C. This device is RoHS compliant, lead-free, and halogen free. It is packaged in a surface mount SOT-23 (TO-236) case with 3 pins. Designed for general purpose switching and amplification applications in low-power circuits.
