This Battrax® device protects SLICs that use both a positive and negative ring voltage. It limits transient voltages with rise times of 100ÂV/µs to Vref ±10 V. Littelfuse's six-pin Battrax® devices are constructed using four SCRs and four gate diodes. The SCRs conduct when a voltage that is more negative than -Vref (and/or more positive than +Vref) is applied to the cathode (Pins 1 and 3) of the SCR. During conduction, the SCRs appear as a low-resistive path which forces all transients to be shorted to ground.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 a VREF = ±48 V. VDRM is measured at IDRM. VS is measured at 100 V/µs. Off-state capacitance is measured at 1MHz with a 2 V bias and is a typical value. "UC"product is approximately 2x the listed value. Positive Battrax information is preliminary data. VREF maximum value for the negative Battrax is -200 V. VREF maximum value for the positive Battrax is 110 V.
