The recommended footprint for the BAT54T-TP is a standard SOT23 package with a minimum pad size of 0.8mm x 0.8mm and a maximum pad size of 1.2mm x 1.2mm.
The BAT54T-TP is rated for operation up to 150°C, but it's recommended to derate the current and voltage ratings above 125°C to ensure reliable operation.
The BAT54T-TP has an internal ESD protection diode, but it's still recommended to follow proper ESD handling procedures when handling the device, such as using an ESD wrist strap or mat.
While the BAT54T-TP can be used as a switch, it's not recommended due to its relatively high forward voltage drop and low current handling capability. A dedicated switch or transistor would be a better choice for switching applications.
The power dissipation of the BAT54T-TP can be calculated using the formula P = Vf x If, where Vf is the forward voltage drop and If is the forward current. The maximum power dissipation is 250mW.
