BC858B Description

Short technical summary and product information.

The BC858B from NXP Semiconductors is a PNP bipolar junction transistor (BJT) suitable for various electronic circuits. It offers a collector-emitter breakdown voltage of 30V and a maximum collector current of 100mA.

 

This transistor operates with a maximum power dissipation of 300mW and has a frequency response up to 200MHz. The Vce saturation voltage is specified at 650mV at 5mA collector current and 100mA base current, with a minimum DC current gain (hFE) of 220 at 2mA collector current and 5V collector-emitter voltage.

 

Packaged in a surface-mount SOT-23-3 configuration, the BC858B is designed for automated assembly processes. Its compact size and electrical characteristics make it a versatile component for signal amplification and switching applications.

 

Compliance information indicates RoHS3 compliance, Moisture Sensitivity Level 1, and REACH unaffected status, though these are noted as low confidence due to unverified sources.
