ELECTRICAL CHARACTERISTICS
(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG1525A/SG1527A with -55 C
SG2525A/SG2527A with -25 C
used which maintains junction and case temperatures equal to the ambient temperature.)
Note 3. These parameters, although guaranteed over the recommended operating conditions, are not 100% tested in production.
Note 4. F
Note 5. Applies to SG1525A/2525A/3525A only, due to polarity of output pulses.
