1N957B thru 1N992B, e3 DO-7

Silicon 500 mW Zener Diodes

S C O T T S D A L E D I V I S I O N

DESCRIPTION

APPEARANCE

DO-7

The popular 1N957B thru 1N992B series of 0.5 watt Zener voltage regulators

provides a selection from 6.8 to 200 volts in standard 5% or 10% tolerances

as well as tighter tolerances identified by different suffix letters on the part

number. The somewhat larger DO-7 packaging option offers a “straight-

through” soldered internal connection with a larger active die element than

otherwise provided in the smaller DO-35 package when needed. Microsemi

also offers numerous other Zener products to meet higher and lower power

applications.

(DO-204AA)

FEATURES

APPLICATIONS / BENEFITS

•

JEDEC registered 1N957B to 1N992B series

•

Regulates voltage over a broad operating current

and temperature range

Internal metallurgical bonding equivalent to “-1” suffix

identification on other military DO-7 Zeners

•

Extensive selection from 6.8 to 200 V

•

Options for screening in accordance with MIL-PRF-

19500 for JAN, JANTX, JANTXV, and JANS are

available by adding MQ, MX, MV, or MSP prefixes

respectively to part numbers.

Standard voltage tolerances are plus/minus 5%

with B suffix, 10 % with A suffix identification

•

Tight tolerances available in plus or minus 2% or

1% with C or D suffix respectively

•

Surface mount equivalents in DO-213AA also

available as MLL957B to MLL992B or with “-1” suffix

(consult factory for other surface mount options)

•

Flexible axial-lead mounting terminals

Nonsensitive to ESD

Capacitance also specified (see Figure 3)

•

RoHS Compliant devices available by adding e3 suffix

Inherently radiation hard as described in

Microsemi MicroNote 050

Smaller DO-35 glass body axial-leaded Zener

equivalents are also available

MAXIMUM RATINGS
