BRT23F

Overview

The BRT23F is a single-channel phototriac output optocoupler featuring an integrated zero-crossing detection circuit. It provides electrical isolation between input and output circuits with a maximum insulation voltage of 5300 Vrms. The device supports a peak repetitive off-state voltage (VDRM) of 800 V and handles an RMS on-state current (IT(RMS)) of 300 mA. Key electrical parameters include a nominal input trigger current (IFT) of 1.2 mA, a maximum forward current of 60 mA, and a maximum turn-on time of 35 µs. It operates within a temperature range of -40 °C to +100 °C.

Feature Summary

• Integrated zero-crossing circuit for reduced electromagnetic interference during switching
• High input sensitivity with low trigger current requirements
• Robust static dV/dt capability to prevent false triggering
• Compliant with RoHS standards using matte tin terminations

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 official Vishay documentation to confirm package type and termination finish. Ensure the procurement source provides valid UL recognition certification data if required for end-product safety compliance. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability constraints.

Selection Notes

Select this component when zero-crossing switching is required to minimize inrush currents and noise in AC loads. The 800 V blocking voltage suits standard mains voltage applications. Verify that the 300 mA load current meets system requirements. Consider the DIP-6 package dimensions for PCB layout compatibility and ensure thermal management aligns with the specified operating temperature range.

Part Context

The BRT23F belongs to the Vishay BRT2x series of phototriac output optocouplers. This family includes variants such as the BRT21F and BRT23H, differentiated by voltage ratings and internal circuitry. The series is designed for general-purpose AC power control applications requiring high isolation and reliable triac triggering capabilities.

Replacement Considerations

Official substitutes within the same Vishay family include the BRT21F and BRT23H. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure the replacement part maintains the required zero-crossing functionality and insulation voltage ratings for the specific application.
