PRODUCT CHANGE This notification serves to inform our customers of the update to the power dissipation (PD) and thermal resistance junction-to-case (ϴJC). Aeroflex Colorado Springs has performed analysis that more accurately represent the PD and ϴJC parameters. Per MIL-STD-883, Method 1012.1, Section 3.4.1, PD = (TJ(max) – TC(max) ) / ϴJC. The SMD will update to reflect the following changes: Parameter ϴJC PD OLD 22°C/W 800mW NEW 15°C/W 1.667W The effective result of this change is the device has better thermal impedance than previously reported. The lower ϴJC permits the user application to reliably dissipate more power. 20. DISPOSITIONARY RECOMMENDATION: 21. ADEPT REPRESENTATIVE CHECK & ☒ USE AS IS 22.
