METALLURGICALLY BONDED GLASS
SURFACE MOUNT 0.5 WATT ZENERS
DESCRIPTION APPEARANCE
The 1N4678UR-1 thru 1N4717UR-1 series of 0.5 watt glass surface mount
DO-213AA Zener voltage regulators provides a selection from 1.8 to 43 volts
in standard 5% tolerances as well as tighter tolerances with a very low test
current of 50 µA. These have an internal-metallurgical-bond option as
identified with the “-1” suffix. This type of internally bonded Zener package
construction is also available with equivalent military screening as described
in the Features section. Microsemi also offers numerous other Zener
products to meet higher and lower power applications.
DO-213AA
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

*JEDEC registered data except IZM has been increased (doubled) for 500 mW power dissipation capabilities
NOTES: 1. These may be ordered as either 1N4678UR-1 through 1N4717UR-1, or as the MLL4678-1 through MLL4717-1.
2. All types as shown are +/-5% tolerance. Also available in 2% and 1% tolerance with added suffix C and D respectively.
3. ∆VZ @ 100µA minus VZ @ 10µA.
The electrical characteristics are measured after allowing the device to stabilize for 20 seconds when mounted with 3/8” minimum lead length from
the base.
