Zeners (BZX85C 3V3 - BZX85C 33) Zeners BZX85C 3V3 - BZX85C 33 Absolute Maximum Ratings* Symbol PD TSTG TJ TA = 25°C unless otherwise noted Tolerance: C = 5% Parameter Power Dissipation Storage Temperature Range Operating Junction Temperature Lead Temperature (1/16” from case for 10 seconds) Value 1.3 -65 to +200 + 200 + 230 Units W °C °C °C *These ratings are limiting values above which the serviceability of the diode may be impaired. NOTES: 1) These ratings are based on a maximum junction temperature of 200 degrees C. 2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
