BZX79C 3V3 - 33 Series Half Watt Zeners Absolute Maximum Ratings* Tolerance: C = 5% TA = 25°C unless otherwise noted Parameter Value Units -65 to +200 °C Maximum Junction Operating Temperature + 200 °C Lead Temperature (1/16” from case for 10 seconds) + 230 °C 500 4.0 30 mW mW/°C W Storage Temperature Range Total Device Dissipation Derate above 25°C Surge Power** *These ratings are limiting values above which the serviceability of the diode may be impaired. **Non-recurrent square wave PW= 8.3 ms, TA= 50 degrees C. DO-35 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.
