Based on hybrid architecture which allows fast switching times with a wide operating ambient temperature range. A high efficient GaAlAs IRED enables low forward current on the input side. On the output side high performance MOSFET switches provide a low RON and can switch both DC and AC signals. - Automatic test equipment ## **AGENCY APPROVALS** - UL 1577 - cUL - DIN EN 60747-5-5 (VDE 0884-5) **ORDERING INFORMATION** ~~Cn~~ **V O R 2 1 2 1 # 8 #** DIP-8 SMD-8 ~~Pr) LJ tJ Fp tI to uo ob od~~ PART NUMBER PACKAGE CONFIGURATION ~~ee ham a=. rs~~ **PACKAGE UL, cUL, VDE** ~~rs~~ SMD-8, tape and reel VOR2121B8T ~~er~~ SMD-8, tube VOR2121B8 DIP-8, tube VOR2121A8 ~~et~~ Rev. 1.2, 31-Aug-2023 Document Number: 84302 **1** For technical questions, contact: optocoupleranswers@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
