The BTA20 Triacs use high performance glass passivated chip technology. The Snubberless concept offers suppression of the RC network and is suitable for applications such as phase control and static switching on inductive or resistive load.
Thanks to their clip assembly technique, the BTA20 Triacs provide a superior performance in surge current handling capabilities.
By using an internal ceramic pad, the BTA series provides voltage insulated tab (rated at 2500 V rms)

IT(RMS)= 20 A
VDRM, VRRM= 600 and 700 V
IGT (Q1)(max) = 35 and 50 mA
Applications
Applications include the ON/OFF function in applications such as static relays, heating regulation, induction motor starting circuits, etc.or for phase control operation in light dimmers, motor speed controllers, and silmilar
The snubberless versions (BTA/BTB...W and T25 series) are especially recommended for use on inductive loads, due to their high commutation performances. The BTA series provides an insulated tab (rated at 2500 VRMS)
