Exceeding any one or combination of these limits may cause permanent damage to this device. 7. M/A-COM Technology Solutions does not recommend sustained operation near these survivability limits. 8. These operating conditions will ensure MTTF > 1 x 106 hours. 9. Junction Temperature (TJ) = TC + jc * (V * I) Typical thermal resistance (jc) = 15 C/W. a) For TC = 25C, TJ = 71C @ 8 V, 385 mA b) For TC = 85C, TJ = 130C @ 8 V, 375 mA Handling Procedures Please observe the following precautions to avoid damage: Static Sensitivity Gallium Arsenide Integrated Circuits are sensitive to electrostatic discharge (ESD) and can be damaged by static electricity. Proper ESD control techniques should be used when handling these devices. An external protection circuit using an inexpensive anti-parallel diode pair can be used to protect the IC.
