Microsemi Corporation
DESCRIPTION
The 1N4765 thru 1N4774A series of Zero-TC Reference Diodes provides a selection of 9.1 V nominal voltages and temperature coefficients to as low as 0.0005%/oC for minimal voltage change with temperature when operated at 7.5 mA. Options for screening similar to JAN, JANTX, JANTXV, and JANS also exist by using MQ, MX, MV or MSP respectively for part number prefixes and high reliability screening. 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 1N935 thru 1N940 series
• Standard reference voltage of 9.1V +/- 5%
• Internal metallurgical bonds
• JANS Equivalent available via SCD
• 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. For example, designate “MX1N4769A” for a JANTX screen
• Radiation Hardened devices available by changing “1N” prefix to “RH”, e.g. RH4769A, RH 4774A, etc. Also consult factory for “RH” data sheet brochure for other radiation hardened reference diode products.
APPLICATIONS / BENEFITS
• Provides minimal voltage changes over a broad temperature range for instrumentation and other circuit designs requiring a voltage reference
• Temperature coefficient selections available from 0.01%/ºC to 0.0005%/ºC
• Tight voltage tolerances available by adding tolerance 1%, 2%, 3%, etc. after part number for further identification, e.g. 1N4773A-2%, 1N4774A-1%, 1N4769-3%, 1N4769A-1%, etc.
• Flexible axial-leaded mounting terminals
• Nonsensitive to ESD per MIL-STD-750 Method 1020
