Surge protection: Failsafe chip varistors for automotive battery lines
TDK Corporation presents a new range of Open Mode chip varistors for electronic automotive assemblies that are directly connected to the battery.
- Open Mode design
- Fulfilment of failsafe requirements according to VW standard VW 80808-1, 2020-03 edition
- Qualified according to AEC-Q200 and VW standard VW 80808-2, 2020-03 edition
- Reliable protection against transients according to ISO 7637-2
The new chip varistors offer reliable protection against transient surge voltages according to ISO 7637-2, and meet the failsafe requirements according to the VW standard VW 80808. Even when subject to excessive bending stress, short-circuits are avoided, which is particularly important for unswitched battery terminals (e.g. terminal 30).
The new surge protection components are designed for an operating voltage of 14 VRMS or a maximum direct voltage of 16 VDC. The three types of the B725*0G1140S862 series are designed for surge currents of 120 A, 200 A and 400 A, with each 8/20 µs. Depending on the surge current capability, the chip varistors are available in sizes EIA 0805, 1206 and 1210, and are suitable for a wide temperature range of -55°C to +150°C.
