Notes Thermal Specifications Parameter Rating Operating Case Temperature Thermal Resistance, Rth (1) Junction Temperature, Tjc (2) -40 to +85 °C 25 °C / W 130 °C 1. The thermal resistance is referenced from the hottest part of the junction to the ground tab (pin 4). 2. This corresponds to the typical biasing condition of +9V, 200 mA at an 85 °C case temperature. A minimum MTTF of 1 million hours is achieved for junction temperatures below 160 °C. 1. Ground / thermal vias are critical for the proper performance of this device. Vias should use a .35mm (#80 / .0135”) diameter drill and have a final plated thru diameter of .25 mm (.010”). 2. Add as much copper as possible to inner and outer layers near the part to ensure optimal thermal performance. 3. Mounting screws can be added near the part to fasten the board to a heatsink. Ensure that the ground / thermal via region contact the heatsink. 4. Do not put solder mask on the backside of the PC board in the region where the board contacts the heatsink. 5. RF trace width depends upon the PC board material and construction. 6. Use 1 oz. Copper minimum. 7. All dimensions are in millimeters (inches). Angles are in degrees.
