At normal temperature (T
A
= 25
°
C), the collector cut-off current I
CEO
is very little (about 1 nA (at V
CE
= 80 V and CTR = about
400% )), but it will be multiplied by about 10 at an increment of 25
°
C. This needs to be kept in mind when using a small output
current (I
C
) of an optocoupler with a high load.
The rate change of V
CE (sat)
(Collector Saturation Voltage) is about 0.7% per
°
C at ambient temperature of 0
°
C to 70
°
C. In circuit
design, the collector output current I
C
should be determined under the condition of half or less of the CTR rated values. Other-
wise, the saturation voltage V
CE (sat)
will become greater.
CHARACTERISTICS OF PS2502 AND PS2506 OPTOCOUPLERS
The PS2502 and PS2506 optocouplers are higher in sensitivity than the PS2501 and PS2505 optocouplers and can be driven by
low currents.
CTR-Related Characteristics
The PS2502 and PS2506 optocouplers assure CTR
⊕
200% at I
F
= 1 mA and can be directly driven by CMOS output signals.
See 3.1 for CTR definition and characteristics.
Change of CTR Over time
Figure 22 shows the CTR vs. time characteristics of the PS2502 and PS2506 optocouplers.
