Criteria of Failure for the Reliability

Measuring Items Symbol Measuring Conditions Judgment Criteria for Failure
Forward voltage Vf lf = 20mA Over Ux1.2
Reverse current Ir Vr = 5V Over Ux2
Luminous intensity Iv If = 20mA Below Sx0.5
MTBF: 100,000 hrs
Note: 1. U, means the upper limit of specified characteristics.  S, means initial value.
2. Measurement shall be taken between 2 hours and after the test pieces have been returned to normal ambient conditions after completion of each test.
3. Ta, means temperature applied.
4. RH, means relative humidity.
5. T.sol, means solder temperature.
