1N746A - 1N759A Series Half Watt Zeners

Absolute Maximum Ratings*	TA = 25°C unless otherwise noted
Parameter		Value	Units
Storage Temperature Range		-65 to +200	°C
Maximum Junction Operating Temperature		+ 175	°C
Lead Temperature (1/16” from case for 10 seconds)		+ 230	°C
Total Device Dissipation		500	mW
Derate above 25°C		3.33	mW/°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.

Tolerance: A = 5%
