Littelfuse, Inc. has introduced the TP6KE Series Automotive TVS Diodes, which are designed specifically 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 standard DO-15 package and high temperature capability with an operating junction temperature (Tj) of up to 175 degrees C. Their superior electrical performance and compact design offers circuit designers the opportunity to upgrade their circuit protection in an existing design footprint or to design more robust protection into new projects than other industry solutions allow.
They are especially 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.

All TP6KE Series Automotive TVS Diodes offer these key benefits: They offer a 600W peak pulse power (Pppm) dissipation rating, which is a very popular power dissipation rating for automotive applications. AEC-Q101 qualified devices like these are well-suited for high reliability applications. Their standard DO-15 axial package and compact footprint allow for quick and easy layout in high reliability applications, including non-PCB designs.
Both uni-directional and bi-directional polarity devices offer 10V to 77V standoff voltage range, which fulfills all design requirements for automotive applications. With an operating junction temperature (Tj) of up to 175 degrees C, they are well suited for high temperature automotive applications, such as for water pumps and turbochargers. Because they comply with IEC 61000-4-2 and IEC 61000-4-4 standards, they help designers meet global regulatory standards. The TP6KE Series is packaged in a standard DO-15 (DO-204AC) package and is provided in tape & reel packaging in quantities of 4,000 and in bulk in quantities of 1,000.
