1N829

1N821-1N829A High-reliability discrete products and engineering services since 1977 TEMPERATURE COMPENSATED ZENER REFERENCE DIODE FEATURES  Available as “HR” (high reliability) screened per MIL-PRF-19500, JANTX level. Add “HR” suffix to base part number.  Available as non-RoHS (Sn/Pb plating), standard, and as RoHS by adding “-PBF” suffix. MAXIMUM RATINGS Operating and storage temperature range DC power dissipation Solder temperatures -65°C to +175°C 500mW @ TL = 25°C and maximum current lZM OF 70mA. For optimum voltage-temperature stability, lZ = 7.5mA (less than 50 mW in dissipated power) 260°C for 10 s (max) ELECTRICAL CHARACTERISTICS (TA = 25°C unless otherwise specified) Part number Zener voltage (Note 1 and 4) VZ @ lZT Zener Test Current lZT Maximum zener impedance (Note 2) ZZT @ lZT Maximum reverse current lR @ 3V Voltage temperature stability (ΔVZT MAX) -55°C to = 100°C (Note 3 and 4) Effective temperature coefficient αVZ VOLTS mA OHMS...
