1N4728A - 1N4752A Series Discrete POWER & Signal Technologies N 1N4728A - 1N4752A Series One Watt Zeners Absolute Maximum Ratings* Tolerance: A = 5% TA = 25C 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 1.0 6.67 10 W mW/C W Storage Temperature Range Total Device Dissipation Derate above 25C 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= 55 degrees C. DO-41 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.
