DESCRIPTION
The popular 1N3154 thru 1N3157A series of Zero-TC Reference Diodes provides a selection of 8.4 V nominal voltages and temperature coefficients to as low as 0.001 %/°C for minimal voltage change with temperature when operated at 10.0 mA. These glass axial-leaded DO-7 reference diodes are also available in JAN, JANTX, and JANTXV military qualifications. As a further option for commercial product, they are available as RoHS Compliant with an e3 suffix added to the part number. 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 1N3154 thru 1N3157A series
• Standard reference voltage of 8.4V +/- 5% with tighter tolerances available
• 1N3154, 3155, 3156, and 3157 also have military qualification to MIL-PRF-19500/158 up to the JANTXV level by adding JAN, JANTX, or JANTXV prefixes to part numbers as well as “-1” suffix, e.g. JANTX1N3157-1, etc.
• Internal metallurgical bonds
• JANS Equivalent available via SCD
• Radiation Hardened devices available by changing 1N prefix to RH, e.g. RH3156, RH3157, RH3157A, etc. Also consult factory for “RH” data sheet brochure
• RoHS Compliant devices available by adding an “e3” suffix (not applicable to military)
APPLICATIONS / BENEFITS
