BS170 Frequently Asked Questions (FAQ)
-
The BS170 can operate safely between -55°C to 150°C, but the recommended operating temperature range is -40°C to 125°C.
-
To ensure the BS170 is fully turned on, the base-emitter voltage (VBE) should be at least 0.7V, and the base current should be sufficient to saturate the transistor.
-
The maximum collector current rating for the BS170 is 500mA, but it's recommended to keep the current below 200mA for reliable operation.
-
While the BS170 can be used as a switch, it's not suitable for high-frequency applications due to its relatively high transition frequency (ft) of 100MHz. For high-frequency applications, consider using a transistor with a higher ft.
-
To protect the BS170 from ESD, use proper handling and storage procedures, and consider adding ESD protection circuits or devices in your design.
