BTA208X-600D,127

Triacs Overview

The BTA208X-600D,127 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT186A (TO-220F) plastic package designed for through-hole mounting. The device features an 8 A RMS on-state current and a 65 A non-repetitive peak on-state current. It supports a rated repetitive peak off-state voltage of 600 V with a maximum junction temperature of +125 °C. This series D variant offers very sensitive gate characteristics, with a maximum gate trigger current of 5 mA across quadrants Q1, Q2, and Q3, facilitating direct interfacing with low power drivers.

Triacs Feature Summary

• High commutation performance suitable for demanding AC switching applications
• Very sensitive gate design optimized for microcontroller and logic IC interfacing
• Planar passivated construction ensures robust reliability and stability

Triacs Applications

• Interfacing with low power drivers including microcontrollers
• AC motor speed control circuits
• Solid state relay implementations

Triacs Procurement Notes

Verify the specific suffix '127' corresponds to the horizontal rail pack packing configuration when sourcing. Confirm RoHS compliance and lead-free status via the official chemical content documentation provided by WeEn Semiconductors. Ensure the ordering part number matches the exact type designation to avoid package or electrical parameter mismatches during procurement.

Triacs Selection Notes

Select this component when circuit requirements demand high commutation capability combined with low gate drive sensitivity. The TO-220F package provides adequate thermal management for 8 A continuous operation. Verify that the 600 V blocking voltage aligns with the system's peak line voltage and transient conditions before finalizing the design.

Triacs Part Context

This part belongs to the BTA208X series of three quadrant triacs from WeEn Semiconductors. The 'Series D' designation specifically denotes the very sensitive gate threshold, distinguishing it from other variants like Series E or F which offer different gate sensitivities. All members share the same core planar passivated structure and TO-220F packaging form factor.

Triacs Replacement Considerations

Cross-reference with BTA208X-600E,127 if slightly higher gate sensitivity is acceptable. Check BTA208X-600D,127 equivalents from other manufacturers ensuring identical TO-220F pinout and 600 V/8 A ratings.
