SURFACE MOUNT  
DESCRIPTION  
ZENER  
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.  
DO-214BA or AC  
(SMAJ)

FEATURES  
APPLICATIONS / BENEFITS  
•
•
•
Zener voltages: 3.3 volts to 200 volts  
Metallurgically bonded  
• For high reliability voltage regulation in low profile  
surface mount locations requiring easy  
placement and strain relief  
• Light weight for airborne or satellite applications  
• Superior surge quality to protect from ESD and  
EFT transients per IEC61000-4-2 and -4-4 and  
higher surge levels defined herein  
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, and JANTXV are available  
by adding MQ, MX, or MV prefixes respectively to part  
numbers. For example, designate a MXSMAJ4460 for a  
JANTX screen.
