BTB08-700BWRG

Triacs Overview

The BTB08-700BWRG is a Snubberless Triac manufactured by STMicroelectronics, designed for general-purpose AC switching applications. It features an RMS on-state current of 8 A and a repetitive peak off-state voltage rating of 700 V. The device utilizes glass passivated chip technology to ensure high reliability and surge current handling capabilities. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger current of up to 50 mA, and a gate trigger voltage of 1.3 V. The component operates within a junction temperature range of -40°C to +125°C and is housed in a TO-220 package with three pins.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC snubber networks, simplifying circuit layout.
• High commutation performance specifically recommended for use with inductive loads.
• Internal ceramic pad provides voltage insulated tab rated at 2500 VRMS compliant with UL standards.

Triacs Applications

• Static relays
• Heating regulation systems
• Induction motor starting circuits
• Phase control operation in light dimmers

Triacs Procurement Notes

Verify the specific voltage rating suffix during procurement, as the BTB08 series includes variants such as 600V and 700V. Confirm that the 'W' suffix denotes the Snubberless version and the 'RG' suffix indicates RoHS compliance. Ensure the TO-220 through-hole package matches the thermal management requirements of the target application before finalizing orders.

Triacs Selection Notes

Select this component when an 8 A AC switch is required for inductive loads without adding external snubber components. The logic-level gate triggering allows direct interface with low-power drivers like microcontrollers. Consider the 2500 VRMS insulation capability if isolation between the heatsink and circuit ground is necessary for safety compliance.

Triacs Part Context

This part belongs to the BTB08 family of standard and Snubberless Triacs from STMicroelectronics. It shares the same physical package and basic switching characteristics with the BTB08-600BWRG but offers a higher voltage blocking capability of 700 V compared to the 600 V variant. The family is optimized for cost-effective AC power control solutions.

Triacs Replacement Considerations

The BTA08-700BWRG serves as a pin-compatible alternative within the same manufacturer's portfolio, offering identical electrical specifications in a different package style. Cross-referencing with other manufacturers requires verifying the 8 A current rating and 700 V blocking voltage to ensure functional equivalence in phase control or static switching roles.
