BTA20

® BTA20 Series 20A TRIACS A2 SNUBBERLESS™ Table 1: Main Features Symbol IT(RMS) VDRM/VRRM IGT (Q1) (max) Value 20 600 and 700 35 and 50 Unit A V mA G A1 DESCRIPTION The BTA20 BW/CW triac family are high performance glass passivated chips technology. The snubberless concept offer suppression of RC network and it is suitable for application such as phase control and static switching on inductive or resistive load. Thanks to their clip assembly technique, they provide a superior performance in surge current handling capabilities. By using an internal ceramic pad, the BTA series provides voltage insulated tab (rated at 2500VRMS) complying with UL standards (File ref.: E81734).
