BTA203-800ETEP

Triacs Overview

The BTA203-800ETEP is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-92 (SOT54) plastic package designed for circuits experiencing high static and dynamic dV/dt and high dI/dt conditions. The device supports an RMS current of 3 A and a peak non-repetitive surge current of 27 A, with a maximum rated junction temperature of 150 °C. It features a blocking voltage of 800 V and a gate trigger current of 30 mA across quadrants Q1, Q2, and Q3. The component achieves full rated RMS current commutation at maximum junction temperature without requiring a snubber circuit.

Triacs Feature Summary

• High commutation capability allows full rated RMS current switching at maximum junction temperature without external snubber assistance
• Three-quadrant operation ensures reliable triggering and conduction across multiple current directions
• Planar passivation technology provides robust protection against environmental stress and electrical transients

Triacs Applications

• Motor control circuits requiring high commutation performance
• Inductive load switching applications
• General purpose AC power control systems

Triacs Procurement Notes

Verify the specific suffix ETEP to confirm the tube packaging configuration, as ordering part numbers may vary based on packing method. Confirm RoHS compliance status and lead-free plating specifications during procurement. Ensure the selected variant matches the required industrial qualification level for the intended application environment.

Triacs Selection Notes

Select this component when a compact TO-92 package is required for low-current AC switching applications. The 3 A RMS rating suits light-duty motor controls or small appliance interfaces. Verify that the 800 V blocking voltage meets the system's peak line voltage requirements. Consider the 150 °C thermal limit for PCB layout and heat dissipation planning.

Triacs Part Context

This triac belongs to the BTA203 series from WeEn Semiconductors, which focuses on high commutation performance in small plastic packages. The series is engineered for industrial applications where space constraints and reliability under high dV/dt conditions are critical design factors.

Triacs Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 3 A TO-92 triacs only if electrical parameters match exactly.
