BC857BTT1G Description

Short technical summary and product information.

The BC857BTT1G is a PNP silicon general purpose transistor from On Semiconductor, housed in the compact SOT-416/SC-75 surface mount package. It is designed for low power general purpose amplifier applications.

 

Key electrical characteristics include a collector-emitter breakdown voltage of -45V, collector-base breakdown voltage of -50V, and continuous collector current of -100mA (peak -200mA). The device offers a DC current gain (hFE) range of 220-475 at IC=-2mA, VCE=-5V, and a typical current-gain bandwidth product of 100MHz. Power dissipation is rated at 200mW on FR-4 minimum pad and 300mW on a 1.0x1.0 inch pad. Thermal resistance junction-to-ambient is 600°C/W for minimum pad and 400°C/W for larger pad.

 

The transistor is Pb-Free and AEC-Q101 qualified (NSV prefix variant), making it suitable for automotive applications requiring stringent quality control. The package is marked with device code 3F. This device is commonly used in signal amplification, switching, and general purpose circuit designs.
