1N821 [Microchip]

These glass axial-leaded DO-35 reference diodes are optionally available with an internal-metallurgical-bond by adding a “-1” suffix. This type of bonded Zener package construction is also available in JAN, JANTX, and JANTXV military qualifications. Microsemi also offers numerous other Zener Reference Diode products for a variety of other voltages up to 200 V. The diodes provide minimal voltage changes over a broad temperature range and are suitable for instrumentation and other circuit designs requiring a stable voltage reference. They feature tight reference voltage tolerances with a center nominal value of 6.15 V and are available with tolerances such as 1%, 2%, 3%, etc. The series offers maximum temperature coefficient selections from 0.01%/ºC to 0.0005%/ºC and has typical low capacitance of 100 pF or less. They are nonsensitive to ESD per MIL-STD-750 Method 1020 and have flexible axial-lead mounting terminals.
