Product Overview

The MOC305X series from Shenzhen Orient Tech Ltd. is a range of non-zero-crossing optoisolators featuring a triac driver output. These devices are designed for high-voltage AC control applications, offering excellent isolation (5,000V rms) and robust performance with high repetitive peak off-state voltage (VDRM min. 600V) and a high critical rate of rise of off-state voltage (dV/dt min. 1000V/s). They are suitable for a wide array of applications including AC motor drives and starters, static power switches, lighting controls, solenoid/valve controls, solid-state relays, and temperature controls. Available in various package types including DIP, wide lead spacing, and surface mounting, with tape and reel options for automated assembly.
