BTS121A Frequently Asked Questions (FAQ)
-
The BTS121A can operate from -40°C to 150°C, but the maximum junction temperature (Tj) should not exceed 150°C.
-
The BTS121A has a thermal pad on the bottom of the package, which should be connected to a heat sink or a copper plane on the PCB to ensure proper heat dissipation.
-
A good PCB layout for the BTS121A should have a solid ground plane, short and wide traces for the high-current paths, and a decoupling capacitor close to the device.
-
Yes, the BTS121A is qualified according to AEC-Q101, which makes it suitable for high-reliability applications such as automotive systems.
-
The BTS121A has built-in overvoltage and overcurrent protection, but additional external protection devices such as TVS diodes and fuses may be necessary depending on the application.
