DESCRIPTION

APPEARANCE

DO-35

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. These are also available in JAN, JANTX, and JANTXV

(DO-204AH)

military qualifications.

Microsemi also offers numerous other Zener

products to meet higher and lower power applications.

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

FEATURES

APPLICATIONS / BENEFITS

• JEDEC registered 1N746 thru 1N759A and 1N4370

•

Regulates voltage over a broad operating

current and temperature range

Selection from 2.4 to 12 V

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

thru 1N4372A series

• Internal metallurgical bond option available by adding

•

a “-1” suffix

• Also available in JAN, JANTX, and JANTXV

qualifications per MIL-PRF-19500/127 by adding the

JAN, JANTX, or JANTXV prefixes to part numbers for

desired level of screening as well as –1” suffix; (e.g.

JANTX1N751A-1, JANTXV1N758C-1, etc.)

•

• Military Surface Mount equivalents also available in

DO-213AA by adding a UR-1 suffix in addition to the

JAN, JANTX, and JANTXV prefix; e.g.

Nonsensitive to ESD per MIL-STD-750 Method

1020

•

Minimal capacitance (see Figure 3)

JANTX1N962BUR-1 (see separate data sheet)
