The CPC1035 is a single-pole, normally open (1-Form-A) solid state relay (SSR) manufactured by Clare, Inc. (now part of IXYS Integrated Circuits Division). It's designed to replace electromechanical relays in various applications, offering advantages such as longer life, faster switching speed, and lower power consumption. The CPC1035 is available in a small 4-Pin SOP package, making it suitable for high-density PCB applications.

Applications

• Telecom Switching
• Instrumentation
• Industrial Controls
• Security Systems
• Medical Equipment

Features

• Single-Pole, Normally Open (1-Form-A) Configuration: Simple on/off switching.
• Solid State Relay (SSR): Provides electrical isolation and long life.
• Low On-Resistance: Minimizes voltage drop and power dissipation.
• High Isolation Voltage: Ensures safety and prevents noise coupling.
• Small 4-Pin SOP Package: Compact size for space-constrained applications.

Benefits

• Long Life: SSRs have no mechanical parts, resulting in significantly longer life compared to electromechanical relays.
• Fast Switching Speed: Provides quick response times for high-speed applications.
• Low Power Consumption: Requires less power to operate compared to electromechanical relays.
• Electrical Isolation: Isolates the control circuit from the load circuit, enhancing safety.
• Reduced Noise: SSRs generate less electrical noise compared to electromechanical relays.

Additional Details

The CPC1035 has a typical on-resistance of around 20 ohms. Its input control current is very low, making it compatible with logic-level control signals. The isolation voltage is typically rated at 1500Vrms or higher, providing excellent protection against voltage transients. The operating temperature range is typically from -40°C to +85°C. The device is often used in applications where reliability and long life are critical requirements, such as in industrial automation and medical equipment. The device turns on when sufficient current is applied to the input LED, and it turns off when the input current is removed.
