BTA208-800F,127

Triacs Overview

The BTA208-800F,127 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT78 (TO-220AB) plastic package and designed for interfacing with low-power drivers and logic ICs, including microcontrollers, in higher noise environments. Key electrical parameters include an RMS on-state current of 8 A, a non-repetitive peak on-state current of 65 A, and a rated repetitive peak off-state voltage of 800 V. The device features a maximum gate trigger current of 25 mA across quadrants Q1, Q2, and Q3, a maximum dV/dt rating of 70 V/µs, and a maximum operating junction temperature of 125°C.

Triacs Feature Summary

• Planar passivated construction for enhanced reliability
• High commutation capability suitable for demanding switching applications
• Three-quadrant operation optimized for compatibility with low-power logic drivers

Triacs Applications

• Interfacing with microcontrollers in noisy industrial environments
• AC power control circuits requiring high commutation performance
• Logic-compatible switching applications utilizing low-power drivers

Triacs Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as the base part number may correspond to different packing options such as horizontal rail packs. Confirm RoHS compliance status and lead-free conversion dates through official manufacturer documentation prior to procurement to ensure alignment with project requirements.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 800 V blocking voltage are required within a TO-220AB package. Ensure the application environment does not exceed the 125°C maximum junction temperature limit. Verify that the gate drive circuit can supply the specified 25 mA trigger current across all operating quadrants to guarantee reliable turn-on.

Triacs Part Context

This triac belongs to the BTA208 series from WeEn Semiconductors, which focuses on balancing commutation performance with gate sensitivity. The 'F' designation typically indicates specific packaging or pinout variations within the broader product family. It serves as a robust solution for AC load control where interference immunity and driver compatibility are critical design constraints.

Triacs Replacement Considerations

Direct substitutes must match the 8 A RMS current, 800 V voltage rating, and TO-220AB package. Verify equivalent dV/dt ratings and gate trigger characteristics to ensure functional parity in existing circuit designs without requiring layout modifications.
