1) Package mounted on PCB 80 ⌠ 80 ⌠ 1.5 mm3; 35← Cu; 5← Sn; Footprint only; zero airflow.

2) Measured to pin 2.

3) Measured to pin 5.

Optimum reliability and life time are guaranteed if the junction temperature does not

exceed 125 C in operating mode. Operation at up to the maximum junction temperature

of 150 C is possible in principle. Note, however, operation at the maximum permitted

ratings could affect the reliability of the device.
