BSS138 Frequently Asked Questions (FAQ)
-
The BSS138 can operate from -55°C to 150°C, but the recommended operating temperature range is -40°C to 125°C.
-
To ensure the BSS138 is fully turned on, the gate-source voltage (Vgs) should be at least 4.5V for a logic-level input, and the drain-source voltage (Vds) should be within the recommended operating range.
-
The BSS138 can handle a maximum continuous drain current (Id) of 1.4A, and a maximum pulsed drain current (Idm) of 4.2A.
-
To protect the BSS138 from overvoltage and ESD, use a voltage clamp or a TVS diode on the drain-source pins, and ensure that the device is handled and stored in an ESD-safe environment.
-
Yes, the BSS138 can be used as a switch for high-frequency signals up to 100 kHz, but the device's parasitic capacitance and inductance should be considered in the design.
