The maximum operating temperature range for BC847AT,115 is -40°C to 150°C.
Yes, BC847AT,115 is a lead-free device, making it RoHS compliant.
The typical current gain (hFE) of BC847AT,115 is 100-400, depending on the collector current.
Yes, BC847AT,115 can be used as a switch, but it's not recommended due to its relatively low collector-emitter saturation voltage (VCE(sat)) and high collector current (IC). A dedicated switch transistor like the PBSS4350X is more suitable for switching applications.
To ensure the reliability of BC847AT,115 in high-temperature applications, follow proper derating guidelines, use a suitable heat sink, and ensure good thermal management. Additionally, consider using a transistor with a higher temperature rating, such as the BC857AT,115.
