BTA201-800ER,112

Triacs Overview

The BTA201-800ER,112 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT54 (TO-92) plastic package and rated for an RMS on-state current of 1 A with a repetitive peak off-state voltage of 800 V. The device features a maximum non-repetitive surge current of 12.5 A and a gate trigger current of 10 mA across quadrants Q1, Q2, and Q3. It operates within a junction temperature range up to +125 °C and offers a dV/dt rating of 600 V/µs.

Triacs Feature Summary

• Designed for interfacing with low power drivers and logic ICs including microcontrollers
• Balances commutation performance and gate sensitivity requirements
• Features reverse pinout configuration compared to standard TO-92 triacs

Triacs Applications

• Low power switching circuits requiring microcontroller interface

• General purpose AC control circuits

Triacs Procurement Notes

Verify the specific suffix '112' against official manufacturer documentation to confirm exact marking and packaging details. Ensure compatibility with the specified SOT54 (TO-92) footprint and reverse pinout arrangement during PCB design. Confirm industrial qualification status if required for the target application environment.

Triacs Selection Notes

Select this component when a compact TO-92 package is required for low current AC switching applications driven by digital logic. The high commutation capability and defined gate sensitivity make it suitable for noise-sensitive environments. Verify that the 1 A RMS current rating meets the load requirements and that the 800 V blocking voltage provides adequate margin for the supply line.
