Innovative High-Reliability Isolation Devices | NATIONSTAR Launches DIP6 Thyristor Optocouplers

As intelligent control moves toward higher reliability and precision, core isolation devices have become critical to system safety.Facing a high-end optocoupler market long dominated by international brands, the industry urgently needs robust, trustworthy domestic alternatives.

Backed by a technical foundation of more than 1,200 patents and full-chain AI intelligent manufacturing capabilities, NATIONSTAR officially launches a new DIP6-packaged thyristor optocoupler. With proprietary core technologies, it injects new security-driven momentum into intelligent control, providing high-end domestic solutions for industrial control, smart home appliances, motor drive and other fields.

As a key component for electrical isolation, signal control and power driving, the reliability of thyristor optocouplers directly determines the overall performance and safety level of systems such as industrial equipment and smart home appliances.

Three Core Breakthroughs Define a New Benchmark for Reliability

NATIONSTAR’s new thyristor optocoupler adopts a highly integrated design of GaAs infrared light-emitting diode + photoelectric bidirectional thyristor, combining high isolation voltage, wide-temperature stability and compact packaging. It builds a safe and sensitive isolation barrier between the input and output of the circuit.

Insulation Strength Breakthrough: 5000Vrms for Full Safety

With an ultra-high isolation voltage of 5000Vrms, the device effectively blocks interference between high-voltage and low-voltage circuits and prevents surge damage to main control chips. It provides dual protection of high-low voltage isolation and anti-interference for applications including PLCs, solenoid valves and AC power switches.

Temperature Adaptability Breakthrough: Stable from -55℃ to 110℃

Thanks to its superior material system and packaging technology, the device maintains stable performance across an ultra-wide operating temperature range, solving performance degradation under extreme temperatures and ensuring long-term reliable operation in harsh industrial, automotive and outdoor environments.

Design Compatibility Breakthrough: DIP6 Package for Flexible Adaptation

The device adopts the classic DIP6 through-hole package for easy installation and strong compatibility. It is available in 5-pin and 6-pin configurations, enabling effortless pin-to-pin replacement.It offers peak breakdown voltages ranging from 250V to 800V and a trigger current as low as 5mA, precisely matching dimming, temperature control, motor speed regulation, relay driving and other scenarios.

Empower All Scenarios and Unlock New Possibilities in Intelligent Control

With its robust core performance, NATIONSTAR DIP6 thyristor optocouplers have become the preferred choice in many key application fields:
