BTA203-800CT/L01EP

Triacs Overview

The BTA203-800CT/L01EP is a three-quadrant triac manufactured by WeEn Semiconductors, designed for AC power control applications. It features an RMS on-state current (I_T(RMS)) of 3 A and a non-repetitive peak on-state current (I_TSM) of 35 A. The device has a rated repetitive peak off-state voltage (V_DRM) of 800 V. Key electrical parameters include a maximum on-state voltage of 1.4 V, a holding current (I_H) of 15 mA, a gate trigger voltage (V_GT) of 700 mV, and a gate trigger current (I_GT) of 10 mA. The component operates within a temperature range of -40°C to +125°C and utilizes a TO-220FP package.

Triacs Feature Summary

• Three-quadrant triggering capability for reliable gate control across all voltage polarities
• Planar passivated construction ensuring high commutation dv/dt immunity
• Through-hole mounting in a TO-220FP package for efficient thermal management

Triacs Applications

• General purpose AC phase control circuits
• Lighting dimmer applications
• Motor speed control systems
• Heating element regulation

Triacs Procurement Notes

Verify the specific suffix L01EP against the manufacturer's latest datasheet to confirm packaging details and compliance status. Ensure the procurement channel provides valid traceability documentation. Cross-reference the part number with official WeEn Semiconductors catalogs to confirm availability and any recent product change notifications before finalizing orders.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 3 A continuous current rating are required for AC switching. The TO-220FP package facilitates direct heatsink mounting for thermal dissipation. Consider the 10 mA gate trigger current for driver compatibility. This triac is suitable for general industrial and consumer AC loads where robust commutation characteristics are necessary.

Triacs Part Context

This part belongs to the BTA series of high-power triacs from WeEn Semiconductors. The series is characterized by planar passivation technology, which enhances reliability under harsh electrical conditions. The BTA203 variant specifically targets applications requiring moderate current handling with high voltage blocking capabilities, fitting between lower-current SMD options and higher-current industrial modules.

Triacs Replacement Considerations

Direct replacements may include the BTA203-800CT or BTA203-800CTQP from the same manufacturer family. Verify pinout compatibility and thermal resistance values when substituting. Other manufacturers' equivalents must match the 800 V V_DRM, 3 A I_T(RMS), and TO-220FP package dimensions.
