Manufacturer:中性打字 Description:where TJ(max) is the maximum allowable junction tempera- ture of the die, which is 125C, and TA is the ambient operat- ing temperature. JA is dependent on the surrounding PC board layout and can be empirically obtained. While the JC (junction-to-case) of the SOT23-5 package is specified at 130C /W, the JA of the minimum PWB footprint will be at least 235C /W. This can be improved upon by providing a heat sink of surrounding copper ground on the PWB. Depending on the size of the copper area, the resulting JA can range from approximately 180C /W for one square inch to nearly 130C /W for 4 square inches. The addition of backside copper with through-holes, stiffeners, and other enhancements can also aid in reducing this value. The heat contributed by the dissipation of other devices located nearby must be included in design considerations. |
