Littelfuse, Inc. Overvoltage Protection - SIDACtor® Protection Thyristors - Connectivity SIDACtor® Protection Thyristors - Series: Bxxx0c_ - B2050CA B2050CA

This is a solid state protection device that can be referenced to either a positive or negative voltage source. The B1xx0C_ is for a -Vref and the B2050C_ is for a +Vref. Designed using an SCR and a gate diode, the B1xx0C_ Battrax® begins to conduct at |-Vref| + |-1.2 V| while the B2050C_ Battrax® begins to conduct at |+Vref| + |1.2 V|.Notes: All measurements are made at an ambient temperature of 25°C. IPP applies to -40°C through +85°C temperature range. IPP is a repetitive surge rating and is guaranteed for the life of the product. IPP ratings assume VREF = ±48 V. VDRM is measured at IDRM. VS is measured at 100 V/µs. Off-state capacitance is measured at 1 MHz with a 2 V bias and is a typical value. “CC” product is approximately 2x the listed value. Positive Battrax information is preliminary data. VREF maximum value for the negative Battrax is -200V. VREF maximum value for the positive Battrax is 110V.
