Build with LTV-217 — Datasheet Specs & AI Design Help

00 — Overview

What the LTV-217 does

The LTV-217 is a single-channel photocoupler featuring a current transfer ratio of at least 50% at 5mA input and 5V output. It provides high isolation voltage of 3,750Vrms and employs double transfer mold technology for reliability. This component holds UL 1577, VDE, and CSA safety approvals while meeting RoHS compliance and halogen-free requirements. The LTV-2x7 series supports HBM 8000V ESD protection and MSL class 1 handling. Engineers typically use these devices in hybrid substrates requiring high-density mounting, programmable controllers, and various system appliances or measuring instruments where electrical isolation is critical.
