PERFORMANCE CHARACTERISTICS (Community)

Running specifications

∗1 rise time : 10 µs, fall time : 160 µs

∗2 rise time : 2 µs, fall time : 10 µs

∗3 This shows a number of operation where it can be running by which a fatal is not caused, and number of operation by wich

a stesdy characteristic is maintained is 1

× 107 times.

∗4 This value is a reference value in the resistive load.

Minimum capacity changes depending on seitching frequency and enviroment temperature and the load.
