Protecting electronics from transient voltage

Littelfuse has introduced the TP6KE Series of automotive TVS diodes, which are designed to protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events.

These AEC-Q101 qualified devices offer a 600W peak pulse power dissipation rating in a DO-15 package with an operating junction temperature of up to 175°C, making them suited for high temperature automotive applications, such as water pumps and turbochargers. Both uni-directional and bi-directional polarity devices offer 10 to 77V standoff voltage range.

The electrical performance and compact design of the TP6KE Series offers circuit designers the opportunity to upgrade their circuit protection in an existing design or to design more robust protection into new projects.

The devices are suitable for use in high density card designs for high reliability and automotive applications; they are also useful for the protection of I/O interfaces, VCC bus and other vulnerable circuits used in telecom, computer, industrial and portable consumer electronics applications.
