BTA08/BTB08 Series 8A Triacs
DESCRIPTION:
With high ability to withstand the shock loading of Large
current, BTA08/BTB08 series triacs provide high dv/dt
rate with strong resistance to electromagnetic interface.
With high commutation performances, 3 quadrants
products especially recommended for use on inductive
load. From all three terminals to external heatsink,
BTA08 provides a rated insulation voltage of 2500 V
RMS
complying with UL standards (File ref: E516503).
