BRT23-H

Overview

The BRT23-H is a phototriac output optocoupler featuring an integrated zero-crossing detector. It provides electrical isolation between input and output circuits with a maximum repetitive peak off-state voltage (VDRM) of 800 V. The device supports a root mean square on-state current (ITRMS) of 300 mA and operates within a temperature range of -40 °C to +150 °C. Key electrical parameters include a forward voltage (Vf) of 1.16 V, a power dissipation (Pd) of 600 mW, and a maximum trigger current (IFT) of 2 mA. The component utilizes a 6-pin DIP package for through-hole mounting.

Feature Summary

• Integrated zero-voltage crossing detection circuitry for reduced electromagnetic interference
• High static dv/dt rating of 10,000 V/µs for noise immunity
• Electrically insulated input and output circuits for safety isolation
• Microcomputer compatible interface with high input sensitivity

Applications

• Solid-state relay driver circuits
• AC motor speed control systems
• Lighting dimmer applications
• Industrial process control interfaces

Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm package type and compliance status. Ensure the ordered variant matches the required isolation voltage and operating temperature range. Cross-reference the ordering part number with official Vishay documentation to avoid discrepancies in pinout or electrical characteristics.

Selection Notes

Select this component when zero-crossing switching is required to minimize inrush currents and EMI. The 800 V blocking voltage suits general AC line applications. Verify that the 300 mA RMS current capacity meets load requirements. Consider the DIP-6 package constraints for PCB layout and thermal management during design integration.

Part Context

The BRT23-H belongs to the Vishay BRT21/BRT22/BRT23 family of phototriac output optocouplers. This series offers various trigger current sensitivities and packaging options. The 'H' suffix typically denotes specific electrical thresholds compared to other variants like 'F' or 'M'. These devices are designed for reliable isolation in AC power control environments.

Replacement Considerations

Compatible substitutes within the same Vishay family include BRT21-H and BRT22-H, provided their voltage ratings and trigger currents align with the application requirements. Verify pin compatibility and insulation specifications before substitution.
