(2) Requirements conditions of SEMI-F47 standard
Table 7.2 shows the permissible time of instantaneous power failure for instantaneous power failure of
SEMI-F47 standard.
Table 7.2 Requirements conditions of SEMI-F47 standard
Instantaneous power

Rated voltage × 80% 1
Rated voltage × 70% 0.5
Rated voltage × 50% 0.2
(3) Calculation of tolerance against instantaneous power failure
Table 7.3 shows tolerance against instantaneous power failure when instantaneous power failure
voltage is "rated voltage × 50%" and instantaneous power failure time is 200 ms.
Table 7.3 Tolerance against instantaneous power failure
(instantaneous power failure voltage = rated voltage × 50%,
instantaneous power failure time = 200 ms)
