BTB08-600SWRG

Triacs Overview

The BTB08-600SWRG is a logic-level triac manufactured by STMicroelectronics, 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 600 V. The device utilizes a TO-220-3 through-hole package with three pins. Key electrical parameters include a maximum gate trigger current (Igt) of 10 mA, a maximum gate trigger voltage (Vgt) of 1.3 V, and a maximum holding current (Ih) of 15 mA. It supports a non-repetitive peak on-state current of 80 A at 50/60 Hz and operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Logic-level gate sensitivity allows direct interfacing with low-power drivers such as microcontrollers without additional buffer circuits.
• Snubberless design capability provides high commutation performance, making it suitable for inductive loads without external snubber networks.

Triacs Applications

• Static relays
• Heating regulation systems
• Induction motor starting circuits
• Light dimmers
• Motor speed controllers

Triacs Procurement Notes

Verify the specific suffix 'W' against official datasheets to confirm Snubberless and logic-level characteristics. Ensure the TO-220-3 package dimensions match the target PCB layout. Confirm RoHS compliance status via the manufacturer's latest documentation before finalizing procurement specifications.

Triacs Selection Notes

Select this component when an 8 A RMS current capacity and 600 V blocking voltage are required in a through-hole configuration. The logic-level gate drive specification makes it appropriate for designs utilizing low-voltage digital control signals. Verify thermal management requirements for the TO-220 package under expected load conditions.

Triacs Part Context

This part belongs to the BTB08 series of 8 A standard and Snubberless triacs from STMicroelectronics. The series offers both through-hole and surface-mount options for general AC switching. The BTB08-600SWRG specifically denotes the 600 V variant with logic-level gate sensitivity and Snubberless performance characteristics.

Triacs Replacement Considerations

Compatible substitutes within the same family include BTB08-600TWRG and BTB08-600BWRG. These variants share identical current and voltage ratings but differ in gate trigger current specifications, requiring verification of driver compatibility during replacement.
