inaccurate delay time.

leakage current may cause an error of delay time. Also, a leakage current over the built-in constant-current

causes unrelease status.

3. Other characteristics

(1) Temperature characteristic of detection voltage.

The temperature characteristics of the detection voltage are expressed by the oblique line parts in Figure 9.

(2) Temperature characteristics of release voltage

The temperature factor (

) of the release voltage is calculated by the temperature factor of the

detection voltage as follows:

The temperature factor of the release voltage has a same sign characteristics as the temperature factor of the

detection voltage.
