MMBD1401 / 1403 / 1404 / 1405
?2002 Fairchild Semiconductor Corporation
MMBD1400 series, Rev. C1
Small Signal Diodes
Absolute Maximum Ratings*
TA
= 25°C unless otherwise noted
*These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
NOTES:
1) These ratings are based on a maximum junction temperature of 150 degrees C.
2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
