1N829AUR

Features:

• Surface mount equivalent of JEDEC registered 1N821 thru 1N829 series
• Internal metallurgical bond option available by adding a "-1" suffix
• Reference voltage selection of 6.2 V & 6.55 V +/-5% with further tight tolerance options at lower voltage
• 1N821, 823, 825, 827 and 829 also have surface mount qualification to MIL-PRF-19500/159 by adding the JAN,
   JANTX, or JANTXV prefixes to part numbers a well as the "-1" suffix; e.g. JANTX1N829- 1, etc.
• Axial-leaded equivalents also available in DO-35 or DO-7 without the UR suffix (see separate data sheet)
   including military qualifications up to JANS for DO-7 (see separate data sheet)
• JANS equivalent available in DO-213AA via SCD  

Application

• Provides minimal voltage changes over a broad temperature range
• For instrumentation and other circuit designs requiring a stable voltage reference
• Maximum temperature coefficient selections available from 0.01%/ºC to 0.0005%/ºC
• Tight reference voltage tolerances available with center nominal value of 6.15 V by adding designated tolerance
   such as 1%, 2%, 3%, etc. after the part number for identification e.g. 1N827UR-2%, 1N829AUR-1-1%, etc.
• Small surface-mount footprint
• Nonsensitive to ESD per MIL-STD-750 Method 1020
• Typical low capacitance of 100 pF or less   

Specifications

• Operating Temperatures:                                                               -65 to +175
• Storage Temperatures:                                                                 -65 to +175
• DC Power Dissipation: 500 mW@ T_L = 25oC and maximum current IZM of 70 mA. 
  NOTE: For optimum voltage-temperature stability, I_Z = 7.5 mA
  (less than 50 mW in dissipated power)
• Solder Temperatures:                                                              260 for 10 s (max) 


Description

The 1N821UR thru 1N829AUR-1 series of surface mount Zero-TC Reference Diodes provides a selection of both 6.2 V and 6.55 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. These glass surface mount DO-213AA (MELF) reference diodes are optionally available with an internal-metallurgical-bond by adding a "-1" suffix. This type of bonded Zener package construction of the 1N829AUR 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.
