CPC1002NTR

Overview

The CPC1002NTR is a miniature, single-pole, normally open (1-Form-A) solid-state relay that utilizes OptoMOS technology to provide 1500Vrms of input-to-output isolation. It is designed to handle DC loads up to 60V and 700mA while requiring only 2mA of LED input current for operation. Its compact 4-pin SOP package makes it an ideal choice for high-density printed circuit board layouts requiring reliable, arc-free switching.

Why Choose This Part

This photorelay eliminates the mechanical wear, contact bounce, and EMI generation associated with traditional electromechanical relays. It offers high sensitivity with a low 2mA trigger current and maintains a small footprint in a 4-pin SOP package. The solid-state design ensures immunity to radiated electromagnetic fields and provides a flammability rating of UL 94 V-0.

Applications

Getting Started

When designing with the CPC1002NTR, ensure the input LED current is limited by a series resistor to at least 2mA for reliable switching. Observe the linear derating curve for load current, which drops from 700mA at 25 degrees Celsius to 420mA at 80 degrees Celsius. Layout should maintain appropriate creepage and clearance distances to preserve the 1500Vrms isolation rating.
