It is constructed using four SCRs and four gate diodes. The SCRs conduct when a voltage that is more negative than -VREF or more positive than +VREF 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 Designs” of this Telecom Design Guide. * “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 VREF = ±48 V.
  • V DRM is measured at IDRM.
  • 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. * Current waveform in µs ** Voltage waveform in µs Electrical Parameters Part Number * VDRM Volts VS Volts VT Volts IDRM µAmps IGT mAmps IT Amps IH mAmps Surge Ratings in Amps Series IPP ITSM 50 / 60 Hz di/dt 0.2x310 * 0.5x700 ** 2x10 * 2x10 ** 8x20 * 1.2x50 ** 10x160 * 10x160 ** 10x560 * 10x560 ** 5x320 * 9x720 ** 10x360 * 10x360 ** 10x1000 * 10x1000 ** 5x310 * 10x700 ** Amps Amps Amps Amps Amps Amps Amps Amps Amps Amps Amps/µs A 20 150 150 90 50 75 75 45 75 20 500 C 50 500 400 200 150 200 175 100 200 50 500 1 32 (T) (-VREF) (R) Ground 4, 6 (+VREF)
