Description
AI
The 1N821UR-1 – 1N829AUR-1 series of surface mount temperature compensated reference diodes provides both 6.2 V and 6.55 V nominal voltages and temperature coefficients as low as 0.0005 %/o C at a Zener test current of 7.5 mA. These glass surface mount DO-213AA (MELF) reference diodes are optionally available as RoHS compliant for commercial applications. This type of bonded Zener package construction is also available in JAN, JANTX, JANTXV and JANS military qualifications (RoHS compliant option not applicable). Microchip also offers other Zener Reference Diode products for a variety of voltages up to 200 V.
