Littelfuse has introduced the TP7.0SMD-XC series of automotive-grade transient voltage suppression diodes. This new series provides robust protection for sensitive vehicle electronics while meeting stringent industry compliance standards.
Why it matters
These components allow design engineers to protect sensitive integrated circuits with low maximum ratings more efficiently. By reducing the overall component count, the series helps manufacturers lower their total bill of materials costs.
The TP7.0SMD-XC series delivers a 24V clamping voltage and functions within an operating junction temperature range of -65°C to 175°C. These diodes feature a compact DO-214AB surface-mount package.
The players
Littelfuse
Littelfuse is a global industrial technology manufacturing company that specializes in circuit protection, power control, and sensing solutions.
The details
The series utilizes advanced foldback technology to maintain a low, flat clamping voltage across diverse conditions. For higher voltage requirements, the devices can be connected in series to provide protection for 48V battery systems.
Timeline
Littelfuse officially announced the launch of the new TVS diode series on October 28, 2026.
Roadmap
The automotive industry is shifting toward more robust, integrated power management systems to support the rapid electrification of vehicle architecture. This launch aligns with the industry-standard AEC-Q101 qualification requirements for critical electronic components.
These components help engineers develop more reliable automotive electronics, potentially leading to fewer electrical system failures in consumer vehicles. The high power capacity ensures that onboard systems remain protected against voltage spikes during jump-starts.
The takeaway
Reliable circuit protection is essential as vehicles incorporate more sensitive digital electronics. Engineers can utilize these high-performance diodes to streamline hardware designs and maintain compliance with critical safety standards.
