B3104U_L Datasheet, PDF (1/2 Pages) Littelfuse – Single Port Positive/Negative SLIC Protector

Battrax® Single Port Positive/Negative SLIC Protector
RoHS
(+V_REF)
This six-pin surface mount package contains programmable protection devices for
5
both negative and positive voltage references.
It is constructed using four SCRs and four gate diodes. The SCRs conduct when a
Ground
4, 6
voltage that is more negative than -V_REF or more positive than +V_REF is applied to
Pin 1 or 3 of the SCR. During conduction, the SCRs appear as a low-resistive path
which forces all transients to be shorted to ground.
For a diagram of a Battrax application, see Figure 6.49 in Section 6, “Reference

* “L” in part number indicates RoHS compliance. For non-RoHS compliant device, delete “L” from part number.
For individual “UA” and “UC” surge ratings, see table below.
General Notes:
• All measurements are made at an ambient temperature of 25 °C. I_PP applies to -40 °C through +85 °C temperature range.
• I_PP is a repetitive surge rating and is guaranteed for the life of the product.
• I_PP ratings assume a V_REF = ±48 V.
• V_DRM is measured at I_DRM.
• V_S is measured at 100 V/µs.
• Positive Battrax information is preliminary data.
• V_REF maximum value for the negative Battrax is -200 V.
• V_REF maximum value for the positive Battrax is 110 V.
