BTB10-800BWRG

Triacs Overview

The BTB10-800BWRG is a bidirectional triac manufactured by STMicroelectronics, rated for 10 A RMS on-state current and 800 V repetitive peak off-state voltage. It utilizes the Snubberless™ technology to enable direct gate triggering of resistive-inductive loads without external RC snubber circuits. The device operates within a junction temperature range of -40°C to +125°C and is housed in an insulated TO-220AB package designed for through-hole mounting.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC snubber networks when switching inductive loads.
• High dV/dt capability ensures reliable operation in noisy environments without false triggering.
• Insulated TO-220AB package provides electrical isolation between the terminal and heatsink.

Triacs Applications

• General AC power switching applications
• Resistive and inductive load control
• Solid-state relays

Triacs Procurement Notes

Verify component authenticity against official STMicroelectronics documentation. Confirm that the specific suffix matches the required insulation and packaging specifications. Check for obsolescence status as distribution availability may vary significantly across regions.

Triacs Selection Notes

Select this component for applications requiring robust inductive load handling without complex external protection circuitry. Ensure the thermal management solution supports the specified operating temperature range and power dissipation requirements for the intended duty cycle.

Triacs Part Context

This part belongs to the BTB10 series of standard and Snubberless triacs from STMicroelectronics. It shares the same current rating and package form factor with variants offering different voltage ratings, such as the 600V version, allowing for flexible design adaptation based on line voltage requirements.

Triacs Replacement Considerations

Direct functional substitutes include other STMicroelectronics Snubberless triacs in the TO-220AB insulated package with equivalent 10A/800V ratings, such as the BTA10-800BWRG, provided pinout compatibility is verified.
