This 1.5 watt zener series in a low-profile light-weight plastic surface mount

configuration, with stress-relief J-bend contacts, meets or exceeds the electrical

performance of the 1N4460 thru 1N4496 and 1N6485 thru 1N6491. It also provides

double the overall surge performance by using a larger active die element. This

includes ESD protection per IEC61000-4-2, EFT protection per IEC61000-4-4, and

higher surge levels defined herein. The low-flat profile provides easier insertion or

automatic handling compared to other MELF style packages. Its thermally efficient

design lowers junction temperatures and extends operating temperature range

before derating begins. Power derates to zero at 150°C for these plastic packages.

Operating temperature: -55°C to +150°C

Storage temperature: -55°C to +150°C
