Small Signal Diode
Absolute Maximum Ratings *
* 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 200degrees C.
2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle
