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.

Notes:
1. No suffix indicates a ±5% tolerance on nominal VZ, C denotes a ±2% tolerance, and D denotes a ±1% tolerance.
2. Zener voltage (Vz) is measured at TL = 30 °C. Voltage measurement to be performed 90 seconds after application of dc current.
3. The zener impedance is derived from the 60 Hz ac voltage which results when an ac current having an rms value equal to 10% of the
dc zener current (IZT or IZK).
4. Vf at 200 mA 1.2 volts maximum and Vf at 1.0 A 1.5 volts maximum.
