BRT23-M

Overview

The BRT23-M is a phototriac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a zero-crossing circuit for low electromagnetic interference switching. The device utilizes a DIP-6 package and provides electrical isolation between input and output circuits. Key electrical parameters include a maximum repetitive peak off-state voltage (VDRM) of 800 V, an RMS on-state current (ITRMS) of 300 mA, and a maximum trigger current (IFT) of less than 2 mA. It operates within a temperature range of -40°C to +150°C.

Feature Summary

• Integrated zero-voltage crossing detector for reduced noise generation
• High static dv/dt capability for improved noise immunity
• Microcomputer compatible input interface with high sensitivity
• Galvanic isolation between input LED and output triac

Applications

• Solid state relay driver circuits
• AC power switching control systems
• Motor speed control applications
• Lighting dimmer circuits

Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to confirm exact voltage ratings and packaging options. Ensure compliance with RoHS directives if required by the target application. Confirm lead times and availability directly with authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when zero-crossing detection is required to minimize inrush currents and EMI. Compare the 800 V blocking voltage against system line voltages. Verify that the 300 mA load current meets the application requirements. Consider the DIP-6 package constraints for PCB layout and thermal management.

Part Context

This part belongs to the BRT21/22/23 family of Vishay phototriac optocouplers. The 'H' suffix typically denotes higher voltage ratings, while 'M' variants may indicate specific packaging or testing configurations. This series is designed for general-purpose AC switching where isolation and noise reduction are critical.

Replacement Considerations

Check equivalent models from other manufacturers offering similar zero-crossing triac outputs. Verify pinout compatibility and isolation voltage ratings before substitution. Ensure the replacement part supports the required ITRMS and VDRM specifications.
