BTA20 Series 20A TRIACS Table 1: Main Features Symbol Value Unit IT(RMS) 20 A VDRM/VRRM 600 and 700 V IGT (Q1) (max) 35 and 50 mA Table 2: Order Codes Part Numbers BTA20-600BWRG BTA20-600CWRG BTA20-700BWRG BTA20-700CWRG 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. Marking BTA20-600BW BTA20-600CW BTA20-700BW BTA20-700CW TO-220AB Insulated A2 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).
