BTA08-700TWRG

Triacs Overview

The BTA08-700TWRG is a logic-level sensitive gate triac manufactured by STMicroelectronics, designed for AC power switching applications. It features an RMS on-state current rating of 8 A and a repetitive peak off-state voltage of 700 V. The device utilizes a TO-220AB through-hole package with three pins. Key electrical characteristics include a maximum non-repetitive surge current of 84 A and a peak on-state voltage of 1.55 V. It operates within a junction temperature range of -40°C to +125°C, ensuring reliable performance in industrial environments.

Triacs Feature Summary

• Logic-sensitive gate architecture enables direct interfacing with standard logic families such as HC, HCT, and LVC.
• High thermal stability supports operation up to 125°C junction temperature for robust industrial use.
• Robust dv/dt immunity minimizes false triggering during rapid voltage transitions.

Triacs Applications

• Solid-state relays requiring high isolation and low control power.
• Industrial motor speed control systems for AC loads.
• General-purpose AC power switching circuits.

Triacs Procurement Notes

Verify the specific suffix 'TWRG' against official STMicroelectronics documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the part number matches the exact voltage rating required for your circuit design before procurement.

Triacs Selection Notes

Select this component when an 8 A RMS current capacity and 700 V blocking voltage are required in a TO-220 package. The logic-sensitive gate feature simplifies driver circuit design compared to standard gate triacs. Verify that the application's peak current does not exceed the 84 A surge rating.

Triacs Part Context

This part belongs to the BTA series of high-current triacs from STMicroelectronics. The BTA08 variant specifically targets applications needing 8 A continuous current handling. The '700' designation indicates the 700 V voltage class, distinguishing it from 600 V or 800 V variants within the same current family.

Triacs Replacement Considerations

Compatible substitutes include the BTA08-600TWRG (600 V rating) or BTA08-800TWRG (800 V rating), provided the voltage margin allows. Other manufacturers offer equivalent 8 A logic triacs in TO-220 packages, but gate trigger specifications must be verified for compatibility.
