Mini-flat package General purpose
Photo Coupler
Features
1. Opaque type, mini-flat package.
2. Subminiature type
(The volume is smaller than that of our conventional DIP type by
as far as 30%).
3. Current transfer ratio
(CTR:MIN.50% at I
F
=5mA, Vce=5V)
4. Isolation voltage between input and output (Viso:3750Vrms).
KPC357NT
UL

Outside Dimension : Unit
(mm)
Applications
1. Hybrid substrates that reguire high density mounting.
2. Programmable controllers.
Classification table of current transfer ratio is
shown below.
