BF158

The STMicroelectronics BF158 is a single, pre-biased bipolar junction transistor (BJT) belonging to the discrete semiconductor product family. This component is designed for use in electronic circuits requiring a pre-configured transistor configuration.

Key specifications include RoHS3 compliance, indicating adherence to environmental standards for hazardous substances. The Moisture Sensitivity Level (MSL) is rated at 1, signifying unlimited usability under standard conditions. The REACH status is unaffected, suggesting compliance with regulations concerning chemical substances.

As a pre-biased transistor, the BF158 simplifies circuit design by integrating base resistors, making it suitable for applications where a specific bias point is required without external components. Its classification within the Transistors - Bipolar (BJT) - Single, Pre-Biased category highlights its specific function in signal amplification and switching.

This part is manufactured by STMicroelectronics, a well-known provider of semiconductor solutions. While specific application details are not provided, pre-biased transistors are commonly used in general-purpose amplification, switching, and logic circuits.
