Leadless Package For Surface Mount Technology Ideal For High Density Mounting Voltage Range To 12 Volts Hermetically Sealed, Double Slug Glass Construction Metallurgically Bonded Construction Available as Dash One. Available in JAN, JTX, Mil-PRF-19500/127 (UR-1 Suffix)

mW DC Power Dissipation (See Power Derating Curve In Figure to +175�C Operating and Storage Junction Temperature

This surface mountable zener diode series is similar to the 1N746 thru 1N759 in the DO-35 equivalent package except that it meets the new JEDEC surface mount outline is an ideal selection for applications of high density and low parasitic requirements. Due to its glass hermetic qualities, it may also be considered for high reliability applications.

Case: Hermetically sealed glass with solder contact tabs at each end. Finish: All external surfaces are corrosion resistant, readily solderable. Polarity: Banded end is cathode. Thermal Resistance: 100�C/Watt Maximum junction to end caps for "-1" construction and 150�C/W maximum junction to end caps for commercial. Mounting Position: Any Weight: 0.04 gm

Note 1 Voltage measurements to be performed 20 seconds after application of dc test current. Note 2 Zener impedance derived by superimposing on IZT 60 Hz rms ac current equal to 10% IZT (2 mA ac). Note 3 Allowance has been made for the increase in VZ due to ZZ and for the increase in junction temperature as the unit approaches thermal equilibrium at the power dissipation at 500 mW. Ordering Information: 1) Commercial: MLL746A thru or MLL746A-1 thru MLL759A-1 MLL4370A thru or MLL4370A-1 thru MLL4372A-1 2) Military: JAN, JANTX, or JANTXV UR-1 3) Tight tolerance "C" suffix = �2%, "D" suffix = �1%
