5. Exceeding any one or combination of these limits may cause
permanent damage to this device.
6. M/A-COM does not recommend sustained operation near
these survivability limits.
7. These operating conditions will ensure MTTF > 1 x 10⁶ hours.
8. Junction Temperature (T_J) = T_A + Ó¨jc * (V * I)
Typical thermal resistance (Өjc) = 73 °C/W.
a) For T_A = 25°C,
T_J = 72 °C @ 5.0 V, 130 mA
b) For T_A = 85°C,
T_J = 129 °C @ 5.0 V, 120 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.
Please reference application note AN3028 on
