AVX (Greenville, SC) has expanded both its TransGuard and Automotive TransGuard Series multilayer varistors to include glass-encapsulated, acid-resistant parts for use in high energy and harsh environment commercial, industrial, and automotive applications. Exhibiting non-linear, bi-directional, V-I characteristics, both zinc-oxide-based ceramic semiconductor device series provide bi-directional over-voltage protection and EMI/RFI attenuation in a single SMT package. The series also feature multi-strike capability, sub 1nS response to ESD strikes, and excellent solderability.   

Ideal for use in harsh environments – such as those utilizing acid, salt, or chlorite flux  – AVX’s glass-encapsulated TransGuard and Automotive TransGuard Series varistors are available in three case sizes (1210, 1812, and 2220), four energy ratings (spanning 2-12J). Features include:

  • Peak current rating of up to 2000A. Both series also have Ni/Sn-plated terminations.
  • RoHS compliant.
  • Rated for use in temperatures spanning -55°C to +125°C.
  • High current and energy handling capabilities.
