T1620W, T1630W
Snubberless™ 16A Triacs
Features
■IT(RMS) = 16 A
■VDRM / VRRM = 600, 700 and 800 V
■IGT = 20 to 30 mA
Description
Based on ST’s Snubberless technology providing
high commutation performances, the
T1620-600W/700W/800W and T1630-600W are
especially recommended for use with inductive
loads such as rice cookers. They comply with UL
standards (ref. E81734).
