Durable MSKSEMI MTLP521-1GB DIP optocoupler ideal for smart meters and office equipment applications
Product Overview
The MTLP521-1XX(DIP)/MTLP521-1XX(SOP) is a controllable optocoupler designed for signal transmission between circuits, providing complete isolation between the front-end and the load. This isolation enhances safety, reduces circuit interference, and simplifies circuit design. It is available in a four-lead package with two form factors: DIP-4 and SMD-4P. Key features include a Current Transfer Ratio (CTR) ranging from 50% to 600% (at IF = 5mA, VCE = 5V) and an input-output isolation voltage of 5000 Vrms. The collector-emitter breakdown voltage (BVCEO) is 80V. Applications include switching power supplies, smart meters, industrial control, measurement instruments, office equipment like copiers, and home appliances such as air conditioners, fans, and water heaters.
