B72500E Series Varistors

TDK Corporation has extended its product range of EPCOS multilayer varistors with the E series, designed to assure protection from current surge pulses in automotive electronics. Thanks to their innovative glass passivation, the SMD protection components are qualified to AEC-Q200 with an extended stress test, even more rugged and reliable than before. The range of their operating voltages extends from 14 VDC to 40 VDC. In addition to greatly reduced leakage currents, the components are characterized particularly by increased temperature stability, up to +150°C. The electrical characteristics of these components remain stable even after exposure to repeated pulses. After the series run-up of the small EIA 0603 and 0805 case sizes at the beginning of 2012, the portfolio has now been extended to include large case sizes up to EIA 2220.

Benefits
  • High operating temperature of up to +150°C
  • Very short response time of 0.5 ns
  • Compliant to AEC-Q200
  • Lead-free and RoHS compliant
Applications
  • ESD protection of bus systems in automotive electronics
