Mini-flat package General purpose
Photo Coupler
KPC357NT
UL 1577 (File No.E169586)
Features
Outside Dimension : Unit (mm)
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 IF=5mA, Vce=5V)
4. Isolation voltage between input and output (Viso:3750Vrms).
Applications
1. Hybrid substrates that reguire high density mounting.
t=0.254+0.05mm
TOLERANCE :+ 0.2mm
2. Programmable controllers.
Schematic : Top View
Classification table of current transfer ratio is
shown below.
1. Anode
2. Cathode
3. Emitter
4. Collector
