BTB24-800CWRG

Triacs Overview

The BTB24-800CWRG is a Snubberless Triac manufactured by STMicroelectronics, designed for general-purpose AC switching applications. It features an RMS on-state current rating of 25 A and supports a non-repetitive peak surge current of 260 A. The device offers a repetitive peak off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 5 µA at VDRM. Key electrical parameters include a peak on-state voltage of 1.55 V, a maximum holding current of 50 mA, and gate trigger specifications of 1.3 V and 35 mA. It operates within a junction temperature range of -40 °C to +125 °C and utilizes a TO-220-3 through-hole package.

Triacs Feature Summary

• Snubberless design capability enabling direct connection to logic circuits without external RC snubber networks
• High commutation performance supporting reliable switching across multiple quadrants
• Low thermal resistance construction optimized for efficient heat dissipation in power applications

Triacs Applications

• General purpose AC switching systems
• Universal motor speed control drivers
• Solid state relays and industrial control modules

Triacs Procurement Notes

Verify the specific suffix 'C' against official STMicroelectronics documentation to confirm exact gate trigger characteristics and commercial grade classification. Ensure the procurement source provides valid RoHS compliance certificates and original manufacturer traceability. Cross-reference the component marking with the datasheet to prevent substitution errors during assembly.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 25 A continuous current capacity are required for AC load control. The Snubberless feature simplifies circuit design by eliminating external protection components. Verify that the application environment remains within the specified -40 °C to +125 °C operating temperature range for reliable long-term performance.

Triacs Part Context

This part belongs to the BTA24/BTB24/T25 family of 25 A Snubberless Triacs from STMicroelectronics. While sharing identical electrical ratings and core functionality, variations exist between the BTA (through-hole), BTB (surface-mount), and T25 series. The BTB24 variant specifically denotes the through-hole TO-220AB packaging configuration used in this model.

Triacs Replacement Considerations

Compatible substitutes within the same family include the BTA24-800BWRG and BTB24-800BRG. These alternatives share identical 25 A/800 V ratings and Snubberless technology. Confirm pinout compatibility and verify that any suffix differences do not alter the gate trigger current requirements before implementation.
