Littelfuse B1200C Battrax slic protector Datasheet

Battrax SLIC Protector
Battrax SLIC Protector
This solid state protection device 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|.
For a diagram of a Battrax application, see Figure 3.38.

* For individual “CA” and “CC” surge ratings, see table below.
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 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. “CC” 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.
