VF Foward Voltage = 1.2 V Maximum @ IF = 200 mA for all 1N4700 series

1N4728A - 1N4752A Series One Watt Zeners

Absolute Maximum Ratings* TA = 25°C unless otherwise noted Tolerance: A = 5%

Electrical Characteristics TA = 25°C unless otherwise noted

@@@

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.

*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.
