BTA10-800BWRG

Triacs Overview

The BTA10-800BWRG is a single-phase triac manufactured by STMicroelectronics, designed for general-purpose AC switching applications. It features an 800 V repetitive peak off-state voltage and an RMS on-state current rating of 10 A. The device utilizes the Snubberless™ technology, allowing it to operate without external RC snubber networks in many resistive and inductive loads. It is housed in an insulated TO-220AB package suitable for through-hole mounting. Key electrical parameters include a maximum gate trigger current of 50 mA, a holding current of 50 mA, and a non-repetitive surge current capability of 105 A. The component operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Snubberless™ technology enables reliable operation without external RC snubber circuits for standard inductive loads.
• Insulated TO-220AB package provides enhanced thermal performance and electrical isolation from heatsinks.
• High dV/dt rating ensures immunity to false triggering during rapid voltage transients.

Triacs Applications

• General-purpose AC power control
• Solid-state relays
• Motor speed control

Triacs Procurement Notes

Verify the specific suffix 'BWRG' against the manufacturer's latest datasheet to confirm RoHS compliance and packaging details. Ensure the ordered part matches the required voltage and current ratings for the target application. Cross-reference with authorized distributors to confirm active status and availability.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 10 A continuous current are required. The Snubberless feature simplifies circuit design by reducing component count. Consider the TO-220AB package size for thermal management requirements and PCB layout constraints compared to smaller surface-mount alternatives.

Triacs Part Context

This part belongs to the BTA series of high-current triacs from STMicroelectronics. It shares the Snubberless architecture with related models like the BTA12 and BTA16, offering improved reliability over traditional triacs. The BTA10 variant specifically targets applications requiring moderate current handling with robust transient protection.

Triacs Replacement Considerations

Direct replacements include the BTA12-800BWRG (higher current) or BTA08-800BWRG (lower current) if pin-compatible. Other manufacturers' equivalents such as the MAC97A6 or BT16-800R may require circuit adjustments due to differing gate characteristics.
