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)

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 V_Z, C denotes a ±2% tolerance, and D denotes a ±1% tolerance.

2. Zener voltage (V_z) is measured at T_L= 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 (I_ZTor I_ZK).

4. V_fat 200 mA 1.2 volts maximum and V_fat 1.0 A 1.5 volts maximum.
