Littelfuse has launched the TP7.0SMD-XC series of automotive-grade transient voltage suppression diodes. These components are designed to protect automotive electronics against high power pulses and electrostatic discharge.
Why it matters
The product enables robust protection for automotive integrated circuits with low absolute maximum ratings. Its design also ensures compliance with automotive 12V and 24V jump-start requirements.
The TP7.0SMD-XC series delivers 7000W of peak pulse power with ESD protection up to 30kV. The diodes feature a 24V clamping voltage and support an operating junction temperature range from -65°C to 175°C.
The players
Littelfuse
Littelfuse is an industrial technology manufacturing company that specializes in circuit protection, power control, and sensing solutions.
The details
Using advanced foldback technology to maintain a flat clamping voltage, these devices allow engineers to consolidate circuitry by replacing multiple series-connected TVS components with a single unit. The series is AEC-Q101 qualified, PPAP capable, and compliant with RoHS standards.
Timeline
Littelfuse launched the TP7.0SMD-XC series on October 14, 2026.
Roadmap
This component release reflects the industry-wide push for smaller, high-density protection solutions within increasingly complex automotive electrical architectures. By standardizing on the DO-214AB package, Littelfuse aligns with global manufacturing trends that prioritize modularity and space efficiency.
While these components are used by automotive manufacturers rather than individual car buyers, their integration helps improve the long-term reliability of vehicle electronics. Increased durability for sensitive ICs can lead to fewer electrical failures over the lifespan of a modern vehicle.
The takeaway
Engineers looking to optimize board space should consider these diodes as a consolidated alternative to multi-component protection arrays. These specifications support the growing demand for reliable electronics in 12V and 24V automotive systems.
