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, 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.

MECHANICAL AND PACKAGING

· Molded epoxy package meets UL94V-0

· Terminals: solderable per MIL-STD-750

Method 2026. (max 260 °C for 10 sec.)

· Body marked with P/N without SMAJ letters

(ie. 4460, 4496, 6485, 4460, etc.)

MAXIMUM RATINGS

· Polarity is indicated by cathode band

· Weight: 0.064 grams (approximate)

· Tape & Reel packaging per EIA-481-2 with 12

mm tape and 2500 units per reel (13 inch reel)

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

Storage temperature: -55°C to +150°C

1.5 watt steady-state maximum power

Thermal resistance, R_?JL= 15 °C/W
