BRT11M

Overview

The BRT11M is a single-channel triac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a gallium arsenide infrared LED coupled to a triac detector, providing electrical isolation between input and output circuits. Key electrical parameters include a maximum RMS on-state current (I_T(RMS)) of 300 mA and a minimum off-state peak voltage (V_DRM) of 400 V. The device supports an insulation voltage of 5300 Vrms and operates within a temperature range of -40 °C to +100 °C. It utilizes a standard 6-pin DIP package.

Feature Summary

• Integrates an infrared emitting diode with a triac photodetector for high-voltage isolation
• Provides robust noise immunity through high common-mode transient rejection capabilities
• Designed for direct interface with logic circuits in AC power control applications

Applications

• Solid-state relays
• AC motor speed control
• Lighting dimmer circuits

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm exact pinout configuration and compliance status. Ensure that the procurement source provides valid traceability records and confirms the component matches the intended electrical specifications for the target application environment.

Selection Notes

Select this component when designing circuits requiring galvanic isolation for low-power AC switching tasks. Consider the 400 V blocking voltage rating relative to the line voltage being controlled. Evaluate the thermal management requirements based on the 300 mA continuous current capability and the specific ambient operating conditions of the final assembly.

Part Context

This device belongs to the BRT series of phototriac output optocouplers from Vishay. These components are engineered for general-purpose AC switching applications where safety isolation is critical. The series offers various voltage ratings and packaging options to suit different industrial and consumer electronics design constraints.

Replacement Considerations

Consult official cross-reference lists for verified substitutes such as the BRT12 or BRT13 variants if higher voltage ratings or zero-crossing functionality are required. Ensure any replacement maintains compatible pin configurations and isolation voltage standards.
