1N941 thru 1N946B-1

11.7 Volt Temperature Compensated Zener

Reference Diodes

SCOTTSDALE DIVISION

DESCRIPTION

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%/

C 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.

FEATURES

•

JEDEC registered 1N941 thru 1N946B series

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

tighter tolerances also available

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

•

APPLICATIONS / BENEFITS

Provides minimal voltage changes over a broad

temperature range

For instrumentation and other circuit designs

requiring a stable voltage reference

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

•

MAXIMUM RATINGS

•

Operating & StorageTemperature: -65

C to +175

•

DC Power Dissipation: 500 mW @ T

= 25

C and

maximum current I

of 39 mA. NOTE: For optimum

voltage-temperature stability, I

= 7.5 mA (less than

95 mW in dissipated power)

•

Solder temperatures: 260

C for 10 s (maximum)

•

MECHANICAL AND PACKAGING

CASE: Hermetically sealed glass case with DO-7

(DO-204AA) package
