1N941 thru 1N946B-1

11.7 Volt Temperature Compensated Zener

Reference Diodes

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

DESCRIPTION

APPEARANCE

The popular 1N941 thru 1N946B series of Zero-TC Reference Diodes

provides a selection of 11.7 V nominal voltages and temperature

coefficients to as low as 0.0002%/^oC for minimal voltage change with

temperature when operated at 7.5 mA. These glass axial-leaded DO-7

reference diodes are also available in JAN, JANTX, and JANTXV military

qualifications. Microsemi also offers numerous other Zener Reference

Diode products for a variety of other voltages from 6.2 V to 200 V.

DO-7

(DO-204AA)

FEATURES

APPLICATIONS / BENEFITS

•

JEDEC registered 1N941 thru 1N946B series

•

Provides minimal voltage changes over a broad

temperature range

Standard reference voltage of 11.7 V +/- 5% with

tighter tolerances also available

For instrumentation and other circuit designs

requiring a stable voltage reference

•

1N941B, 942B, 943B, 944B, 945B also have military

qualification to MIL-PRF-19500/157 up to the

JANTXV level by adding JAN, JANTX, or JANTXV

prefixes to part numbers as well as “-1” suffix, e.g.

JANTX1N944B-1, etc.

Internal metallurgical bonds

JANS Equivalent available via SCD

Radiation Hardened devices available by changing

“1N” prefix to “RH”, e.g. RH944B, RH945B, etc.

Also consult factory for “RH” data sheet brochure

Maximum temperature coefficient selections

available from 0.01%/ºC to 0.0002%/ºC

Tight reference voltage tolerances available at 11.7

V nominal values by adding the tolerance 1%, 2%,

3%, etc. after the part number for further

identification e.g. 1N944B-2%, 1N945A-1%,

1N944B-1-1%, etc.

Flexible axial-lead mounting terminals

Nonsensitive to ESD per MIL-STD-750 Method 1020
