MOC302
A Triac output optoisolator, the MOC302 from Lite-On Inc. is part of the MOC302x series. This makes it a good fit for applications where using a solid-state relay to precisely control AC power loads is necessary.
Description
Features
The MOC302 is a 6-pin DIP photocoupler from the MOC302x series by Lite-On Inc. that has a triac driver output. For safe electrical use, it offers strong isolation with 5000Vrms between input and output. Its triac output, which has a minimum off-state voltage (VDRM) of 400V and can withstand high repetitive peak off-state voltage, is specifically made for switching AC loads. With a minimum of 1000 µs, the device guarantees effective switching with a high critical rate of rise of off-state voltage (dv/dt). It provides flexibility in triggering and holding the triac output thanks to its LED trigger current (Ift) of up to 5mA and hold current (Ih) of 250µA (Standard). Operating within the temperature range of -40°C to 100°C, it exhibits good environmental adaptability.
MOC302 in AC Switching and Power Tool Control
- The MOC302 series is crucial for managing electric tools and for turning on and off AC switches, such as those in lights and motors. It is safe because it uses an optocoupler to keep the control portion isolated from high-voltage AC power. The optocoupler's output helps to precisely and reliably control AC loads by triggering power components like SCRs and TRIACs. This kind of starts and stops motors to give precise speed control for electric tools. When used with power devices, it ensures good performance under a range of loads and conditions in industrial machines, automation systems, and home tools.
