The Vishay VOS618A-2T is a member of the VOS618A optocoupler series in a 4-pin SSOP-4, 50 mil pitch mini-flat package.
In this variant, the “-2” designation corresponds to a current transfer ratio (CTR) bin of 63 % to 125 % (IF = 1 mA, VCE = 5 V).
The device offers high isolation (3750 VRMS), ultra-low coupling capacitance, and compact form to enable efficient isolation between two circuits with minimal board space and input drive.
Features
-
CTR in the 63 %–125 % range enabling moderate input current designs.
-
Low-profile SSOP-4 package (half-pitch, 50 mil lead spacing).
-
High collector-emitter voltage 80 V.
-
High isolation test voltage 3750 VRMS.
-
Low coupling capacitance enabling better signal integrity in high common-mode environments.
-
Material categorization and compliance.
Specifications
-
CTR (IF = 1 mA, VCE = 5 V): min 63 %, max 125 %.
-
Other key specs match the general series: VCEO 80 V, VIORM 565 Vpeak, etc. (see previous section).
Applications
-
Industrial control modules where moderate CTR is sufficient and cost/space optimization is needed.
-
Telecom interface circuits requiring isolation but lower drive current requirements.
-
Office machines and battery-powered portable devices.
-
Programmable logic or input-sensor isolation circuits in embedded systems.
