DESCRIPTION

APPEARANCE

The popular 1N746 thru 1N759A and 1N4370 thru 1N4372A series of 0.5

watt Zener Voltage Regulators provides a selection from 2.4 to 12 volts in

standard 5% or 10% tolerances as well as tighter tolerances identified by

different suffix letters on the part number. These glass axial-leaded DO-35

Zeners are also available with an internal-metallurgical-bond option by

adding a “-1” suffix as well as RoHS Compliant by adding an “e3” suffix.

Microsemi also offers numerous other Zener products to meet higher and

lower power applications.

DO-35

(DO-204AH)

•

Regulates voltage over a broad operating

current and temperature range

thru 1N4372A series

• Internal metallurgical bond option available by adding a

•

Selection from 2.4 to 12 V

“-1” suffix similar to military devices

Standard voltage tolerances are plus/minus 5%

with A suffix identification and 10 % with no suffix

Tight tolerances available in plus or minus 2%

or 1% with C or D suffix respectively

Flexible axial-lead mounting terminals

• Commercial Surface Mount equivalents available as

MLL746 to MLL759A and MLL4370 to MLL4372A

including the “-1” suffix in the DO-213AA MELF style

package (consult factory for others)

•

• RoHS Compliant devices available by adding “e3” suffix

Nonsensitive to ESD per MIL-STD-750 Method

1020

• DO-7 glass body axial-leaded Zener equivalents are

also available

•

Minimal capacitance (see Figure 3)

Inherently radiation hard as described in Microsemi

MicroNote 050

MAXIMUM RATINGS
