Stable voltage MICROCHIP 1N825A temperature compensated zener diode for in instrumentation designs
Product Overview
The Microsemi 1N821 thru 1N829A-1 series are 6.2V and 6.55V Temperature Compensated Zener Reference Diodes designed for applications requiring minimal voltage change with temperature. These diodes offer selectable temperature coefficients down to 0.0005%/C when operated at 7.5 mA. They are available in a DO-35 glass axial-leaded package and optionally feature an internal metallurgical bond (indicated by a "-1" suffix). Military qualifications including JAN, JANTX, and JANTXV are available for specific part numbers. These diodes are suitable for instrumentation and circuit designs demanding a stable voltage reference and are non-sensitive to ESD.

Note: Double Anode; electrical specifications apply under both bias polarities. Add "-1" suffix for internal metallurgical bond. Tighter voltage tolerances can be ordered with a hyphened suffix (e.g., 1N827-1-2%). Zener impedance measured by superimposing 0.75 mA ac rms on 7.5 mA dc @ 25C. Voltage measurements performed 15 seconds after application of dc current.
