Zener Diode Features: * * * * High reliability. Very sharp reverse characteristic. Low reverse current level. Vz-tolerance 5%. Application: Voltage stabilization. Absolute Maximum Ratings Tj = 25C Parameter Test Conditions Symbol Value Unit Power dissipation Tamb 50C Pv 1 W Z-current - Iz Pv / Vz mA Junction temperature - Tj 200 Storage temperature range - Tstg -65 to +175 Parameter Test Conditions Symbol Value Unit Junction ambient I = 9.5 mm (3/8") TL = constant RthJA 100 K/W C Maximum Thermal Resistance Tj = 25C Stresses exceeding maximum ratings may damage the device. Maximum ratings are stress ratings only. Functional operation above the recommended operating conditions is not implied. Extended exposure to stresses above the recommended operating conditions may affect device reliability.
