BRT23H

Overview

The BRT23H 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 current of 60 mA, a forward voltage of 1.16 V, and a power dissipation of 600 mW. The unit utilizes a DIP-6 package for through-hole mounting.

Feature Summary

Integrated zero-voltage crossing detection circuitry
High static dv/dt capability for noise immunity
Microcomputer compatible input interface
Electrically insulated input and output sections

Applications

Solid state relay driver circuits
AC motor control systems
Lighting control applications
Heater control interfaces

Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm package type and compliance status. Ensure the selected variant matches the required insulation voltage and operating temperature range for the target application environment.

Selection Notes

Select this component when phase-independent AC switching is required. The built-in zero-crossing feature minimizes electromagnetic interference during turn-on. Confirm that the load current remains within the 300 mA RMS limit and that the system voltage does not exceed the 800 V blocking rating.

Part Context

This part belongs to the Vishay BRT21/22/23 series of phototriac output optocouplers. The series offers variations in trigger current sensitivity and voltage ratings. The BRT23H specifically denotes the high-voltage 800 V variant with standard trigger characteristics suitable for general-purpose AC switching.

Replacement Considerations

Check for direct substitutes such as BRT21H or BRT22H if lower voltage ratings are acceptable. Verify pinout compatibility and insulation requirements before substituting with other manufacturers' zero-crossing triac optocouplers.

FAQ

What is the purpose of the zero-crossing circuit in the BRT23H?

The zero-crossing circuit ensures the triac turns on only when the AC line voltage is near zero, reducing inrush current and electromagnetic interference.
