BTA201-800E,112

Triacs Overview

The BTA201-800E,112 is a bidirectional triac manufactured by WeEn Semiconductors. It features an RMS on-state current (It RMS) of 1 A and a non-repetitive peak on-state current of 9 A. The rated repetitive peak off-state voltage (VDRM) is 800 V. Key electrical parameters include a maximum on-state voltage of 1.5 V, a maximum holding current (Ih) of 15 mA, a gate trigger voltage (Vgt) of 800 mV, and a gate trigger current (Igt) of 10 mA. The device operates within a junction temperature range of -40°C to +125°C and is housed in a TO-220F-3 package.

Triacs Feature Summary

• Bidirectional switching capability for AC load control applications
• High thermal stability with a maximum operating temperature of +125°C
• Robust construction supporting high surge currents up to 9 A

Triacs Applications

• AC motor speed control circuits
• Solid-state relay designs
• Lighting dimmer switches

Triacs Procurement Notes

Verify the specific suffix '112' against official manufacturer documentation to confirm the exact packaging configuration, as suffixes often denote reel or tube variations rather than functional differences. Ensure the component source is authorized to guarantee authenticity and traceability. Cross-reference the datasheet revision date to confirm compliance with current environmental standards such as RoHS.

Triacs Selection Notes

Select this component when a 1 A RMS current rating and 800 V blocking voltage are required for through-hole mounting. The TO-220F-3 package facilitates effective heat dissipation compared to smaller surface-mount alternatives. Verify that the gate trigger current of 10 mA is compatible with the driving circuit's output capabilities before finalizing the design.

Triacs Part Context

This part belongs to the BTA series of general-purpose triacs from WeEn Semiconductors. It shares the same die specifications and electrical characteristics as other variants in the BTA20x family, differing primarily in packaging and marking. The TO-220F-3 form factor provides a standardized footprint for industrial PCB layouts requiring robust thermal management.

Triacs Replacement Considerations

Direct pin-compatible substitutes include the BTB201-800E and STMicroelectronics BTA201-800E. These alternatives maintain identical electrical ratings and package dimensions, allowing for drop-in replacement without circuit modification.
