= 25°C unless otherwise noted

Value Units

PD Power Dissipation 1.3 W T

Storage Temperature Range -65 to +200

STG

TJ Operating Junction Temperature + 200 Lead Temperature (1/16” from case for 10

+ 230

seconds)

*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.
