BTA208-600B,127

Triacs Overview

The BTA208-600B,127 is a RAIL 3Q Triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 8 A and a non-repetitive peak on-state current of 71 A. The device has a rated repetitive peak off-state voltage of 600 V and a maximum off-state leakage current of 100 uA at VDRM. Key electrical parameters include an on-state voltage of 1.3 V, a maximum holding current of 12 mA, a gate trigger voltage of 700 mV, and a gate trigger current of 10 mA. It operates within a temperature range of -40°C to +125°C and uses a TO-220AB-3 through-hole package.

Triacs Feature Summary

• Rail 3Q technology for improved switching performance
• Through-hole mounting in TO-220AB-3 package
• High thermal stability up to 125°C junction temperature

Triacs Applications

• Lighting control systems
• Motor speed control applications
• General purpose AC power switching

Triacs Procurement Notes

Verify the specific suffix '127' corresponds to the tube packaging format as indicated in distributor listings. Confirm RoHS compliance status via the manufacturer's official documentation before integration. Ensure the ordering part number matches the exact electrical characteristics required for the target circuit design.

Triacs Selection Notes

Select this component for applications requiring 8 A RMS current handling with 600 V blocking capability. The TO-220AB-3 package facilitates heat dissipation for moderate power levels. Consider the 10 mA gate trigger current when designing the driving circuitry to ensure reliable turn-on under all operating conditions.

Triacs Part Context

This triac belongs to the BTA series from WeEn Semiconductors, designed for general-purpose AC control. The RAIL 3Q variant offers enhanced dV/dt immunity compared to standard triacs. It is suitable for industrial and consumer electronics where robust AC switching is required.

Triacs Replacement Considerations

Equivalent parts include BTA208-600E,127 and BTA208X-600E,127 from the same manufacturer. Verify pinout compatibility and thermal resistance differences when substituting.
