Value
Units
IFRM Repetitive Peak Forward Current (IFRM) 250 mA
IZRM Repetitive Peak Working Current (IZRM) 250 mA
PD Power Dissipation 350 mW
TSTG Storage Temperature Range -55 to +150 °C
TJ Operating Junction Temperate -55 to +150°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 150 degrees C.
2) These are steady state limits. The factory should be consulted on applications involving pulsed
or low duty cycle operations.
