SMAJ4460 thru SMAJ4496
and SMAJ6485 thru SMAJ6491
1.5 Watt Zener Diodes
DESCRIPTION
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.

ZENER
DO-214BA or AC
(SMAJ)
FEATURES
• Zener voltages: 3.3 volts to 200 volts
• Metallurgically bonded
• Reliability data per JESD22-A108, JESD22-A104,
JESD22-A113-B, JESD22-A101-B, and JESD22-A102
• Thermally efficient surface mount with J-bends for
stress relief (flat handling surface for easier placement)
• Options for screening in accordance with MIL-PRF-
19500/406 for JAN, JANTX, JANTXV, and JANS are
available by adding MQ, MX, MV, or MSP prefixes
respectively to part numbers. For example, designate a
MXSMAJ4460 for a JANTX screen.
MAXIMUM RATINGS
• Operating temperature: -55°C to +150°C
• Storage temperature: -55°C to +150°C
