Absolute Maximum Ratings
Operation of this device beyond any one of these limits may
cause permanent damage. For reliable continous operation,
the device voltage and current must not exceed the maximum
operating values specified in the table on page one.
Bias Conditions should also satisfy the following expression:
IDVD < (TJ - TL) / RTH, j-l

NOTE: While the SNA-686 can be operated at different bias currents, 65 mA is the recommended bias for
lower junction temperature and longer life. This reflects typical operating conditions which we have found
to be an optimal balance between high IP3 and MTTF. In general, MTTF is improved to more than 100,000
hours when biasing at 65 mA and operating up to 85°C ambient temperature.
