Description

The DC60MP is a DC-controlled solid-state relay (SSR) capable of switching up to 60VDC at 3A, designed in a compact epoxy-encapsulated package for PCB mounting. It features high optical isolation, robust surge handling, and integrated heat-spreader technology for improved thermal performance and long-term reliability. This relay is widely used in industrial control, automation systems, and high-density PCB relay applications.

Features

• Switching capability up to 60VDC and 3A load current
• 4,000V optical isolation between input and output
• Rugged epoxy encapsulated construction
• High surge tolerance with pre- and post-test validation
• Integrated heat-spreader for efficient thermal dissipation
• Designed for high-density PCB mounting

Absolute Maximum Ratings (Tc = 25 °C)

Design Notes

• Ensure adequate PCB copper area for heat dissipation despite built-in heat spreader
• Use proper input current limiting resistor for LED drive inside SSR
• Consider leakage current in off-state for sensitive loads
• Snubber circuits may be required for inductive loads
• Verify thermal derating at elevated ambient temperatures

Typical Circuit Usage

• DC load switching in industrial control systems
