These are stress ratings only. Functional operation of the device at these or any conditions beyond the "recommended
operating conditions" is not implied. Exposure to absolute maximum rated conditions may affect device reliability.
NOTES:
1. Voltage values are with respect to the anode except as noted.
2. Maximum power dissipation is a function of T
, q and T . Maximum allowable power dissipation at any allowable ambient temperature is
