The 1N4775 thru 1N4784A series of Zero-TC Reference Diodes provides a selection of 8.5 V nominal voltages and temperature coefficients to as low as 0.0005%/°C 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. Microchip also offers numerous other Zener Reference Diode products for a variety of other voltages from 6.2 V to 200 V
