BTA08-700CWRG

Triacs Overview

The STMicroelectronics BTA08-700CWRG is a Snubberless Triac designed for general-purpose AC 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-220 package with through-hole mounting and provides three pins. Key electrical parameters include a maximum gate trigger current of 5 mA, a maximum gate trigger voltage of 1.3 V, and a peak on-state voltage of 1.55 V. It supports a surge current rating of 84 A and operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Snubberless design optimized for high commutation performance on inductive loads
• Logic level interface capability for direct connection to low power drivers such as microcontrollers
• Fully insulated package providing 2500 VRMS isolation via internal ceramic pad

Triacs Applications

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

Triacs Procurement Notes

Verify the specific voltage grade suffix during procurement, as the BTA08 series includes variants rated at 600 V, 700 V, and 800 V. Confirm that the 'W' suffix corresponds to the Snubberless version required for your application. Ensure the TO-220 package type matches your board layout requirements. Check RoHS compliance status against current regulatory standards before finalizing orders.

Triacs Selection Notes

Select this component when an 8 A RMS current capacity and 700 V blocking voltage are required for AC load control. The Snubberless characteristic makes it suitable for inductive loads without external RC snubber networks. Consider the logic-level gate sensitivity if interfacing directly with low-power digital outputs. Evaluate thermal management needs based on the TO-220 package's thermal resistance characteristics.

Triacs Part Context

This part belongs to the BTA series of standard and Snubberless Triacs from STMicroelectronics. The series offers various current ratings from 6 A to 24 A and voltage ratings from 600 V to 800 V. The BTA08 variant specifically targets applications requiring moderate current handling with high commutation reliability. The series is UL1557 certified and compliant with RoHS directives.

Triacs Replacement Considerations

Publicly confirmed substitute part numbers for the BTA08-700CWRG were not identified in the provided source material. Verify compatibility with alternative manufacturers' 8 A, 700 V Snubberless Triacs in the TO-220 package by comparing electrical parameters and pin configurations.
