BT168G,112

Scrs Overview

The BT168G,112 is a glass passivated, sensitive gate thyristor manufactured by WeEn Semiconductors. Designed for logic-level triggering, it features a plastic envelope suitable for Residual Current Devices (RCD), Ground Fault Interrupters (GFI), and Leakage Current Circuit Breakers (LCCB). The component allows direct interfacing with microcontrollers, logic integrated circuits, and other low-power gate trigger circuits where a minimum gate trigger current limit is required.

Scrs Feature Summary

• Sensitive gate architecture enabling direct interface with microcontrollers and logic ICs
• Glass passivation for enhanced environmental stability
• Logic-level operation optimized for applications requiring minimal gate trigger current

Scrs Applications

• Residual Current Devices (RCD)
• Ground Fault Interrupters (GFI)
• Leakage Current Circuit Breakers (LCCB)

Scrs Procurement Notes

Verify the manufacturer designation on official documentation, as the model prefix BT168 is historically associated with NXP Semiconductors. Confirm that the specific suffix ,112 corresponds to the WeEn Semiconductors production line and packaging specifications. Ensure the datasheet explicitly lists WeEn Semiconductors as the source to validate authenticity and technical parameters.

Scrs Selection Notes

Select this component when designing protection circuits that require direct logic-level control without additional driver stages. It is appropriate for systems needing a sensitive gate thyristor to minimize gate drive power consumption. Verify that the application environment is compatible with the plastic envelope construction and that the thermal management requirements align with the device's package capabilities.

Scrs Part Context

This thyristor belongs to the family of logic-level sensitive gate devices intended for safety-critical switching applications. It serves as a core switching element in residual current detection mechanisms, providing reliable latching behavior triggered by low-current signals from control electronics.

Scrs Replacement Considerations

The BT148 and BT149 are documented similar parts within the same logical series offering comparable logic-level thyristor characteristics. Verify pinout compatibility and specific electrical limits before substitution.
