Battrax Quad Negative SLIC Protector Battrax Quad Negative SLIC Protector (T) 6 Ground 5 (R) 4 This Battrax device is an integrated overvoltage protection solution for SLIC-based (Subscriber Line Interface Circuit) line cards. This six-pin device is constructed using four SCRs and four gate diodes. The device is referenced to VBAT and conducts when a voltage that is more negative than -VREF is applied to the cathode (pins 1, 3, 4, or 6) of the SCR. During conduction, all negative transients are shorted to Ground. All positive transients are passed to Ground by steering diodes. For specific diagrams showing these Battrax applications, see Figure 3.37. 1 (T) 2 (-VREF) 3 (R) Electrical Parameters Part Number * B1101U_4 ** B1161U_4 ** B1201U_4 ** VDRM Volts |-VREF| + |-1.2V| |-VREF| + |-1.2V| |-VREF| + |-1.2V| VS Volts |-VREF| + |-10V| |-VREF| + |-10V| |-VREF| + |-10V| VT Volts 4 4 4 IDRM µAmps 5 5 5 IGT mAmps 100 100 100 IT Amps 2.2 2.2 2.2 IH mAmps 100 160 200 CO pF 50 50 50 * For individual “UA” and “UC” surge ratings, see table below. ** Contact factory for release date. General 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 (CO) is measured at 1 MHz with a 2 V bias and is a typical value. “UC” product is approximately 2x the listed value. • VREF maximum value for the negative Battrax is -200 V.
