BTB08-600BRG

Triacs Overview

The STMicroelectronics BTB08-600BRG is a three-terminal triac designed for general-purpose AC switching applications. It features an RMS on-state current rating of 8A and a repetitive peak off-state voltage of 600V. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220AB through-hole package with three pins. Key electrical parameters include a maximum gate trigger current of 50mA, a maximum gate trigger voltage of 1.3V, and a peak on-state voltage of 1.55V. The component supports a non-repetitive surge current of 84A and maintains a maximum holding current of 50mA.

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
• Through-hole mounting configuration suitable for standard PCB assembly

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 suffix 'RG' against official manufacturer documentation to confirm RoHS compliance status and manufacturing origin. Ensure the ordering part number matches the exact pinout and thermal characteristics required for the target application circuit design.

Triacs Selection Notes

Select this component when an 8A RMS current capacity at 600V blocking voltage is required for AC load control. The Snubberless feature makes it suitable for inductive loads without external RC snubber networks. Verify that the driving circuit can supply the specified 50mA gate trigger current reliably across the operating temperature range.

Triacs Part Context

This device belongs to the BTB08 series of standard and Snubberless triacs from STMicroelectronics. The series offers both through-hole and surface-mount options for general purpose AC switching. The BTB08 variants are engineered to provide reliable performance in phase control and ON/OFF switching applications across various industrial and consumer electronics sectors.

Triacs Replacement Considerations

Compatible substitutes within the same family include BTB08-600BWRG and BTB08-600TWRG. These alternatives share identical electrical ratings but may differ in packaging or specific commercial suffixes. Verify pin compatibility and thermal resistance specifications before substitution.
