BF258

The ST BF258 is an NPN High Voltage Transistor designed for general purpose applications. This component is manufactured by STMicroelectronics and falls under the category of Discrete Semiconductor Products, specifically Transistors - Bipolar (BJT) - Single, Pre-Biased.

Key compliance information indicates that the BF258 is RoHS3 Compliant and has a Moisture Sensitivity Level (MSL) of 1, meaning it has unlimited shelf life under recommended storage conditions. The REACH status is noted as unaffected.

While specific electrical and mechanical specifications such as collector-emitter voltage, collector current, power dissipation, gain (hFE), and transition frequency are not detailed in the provided information, its classification as a high voltage transistor suggests suitability for applications requiring elevated voltage handling capabilities. Further details would typically be found in the manufacturer's datasheet.

This transistor is suitable for various electronic circuits requiring amplification or switching functions where high voltage operation is a requirement. Its pre-biased nature simplifies circuit design by integrating base biasing resistors.
