1N746A - 1N759A Series Discrete POWER & Signal Technologies 1N746A - 1N759A Series Half Watt Zeners Absolute Maximum Ratings* Parameter Storage Temperature Range Maximum Junction Operating Temperature Lead Temperature (1/16” from case for 10 seconds) Total Device Dissipation Derate above 25°C TA = 25°C unless otherwise noted Tolerance: A = 5% Value -65 to +200 + 175 + 230 500 3.33 Units °C °C °C mW mW/°C *These ratings are limiting values above which the serviceability of the diode may be impaired. 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.
