Semiconductor Event Showcases China's Chip Power

From March 26-28, the highly anticipated SEMICON/FPD China 2025, with the theme "Cross-Border Global, Heart-to-Heart Connection," was grandly held at the Shanghai New International Expo Centre. As the largest semiconductor event in Asia, this year’s exhibition attracted over 1,200 companies from around the world, showcasing the latest technological advancements in semiconductor manufacturing, design, materials, equipment, and more. At this industry feast, leading domestic semiconductor company Slkor unveiled its latest development, the SMF7.5A Transient Voltage Suppression (TVS) diode, demonstrating China's technological strength in circuit protection devices.

Precise Protection: Technical Features of the SMF7.5A

The SMF7.5A, newly launched by Slkor, is a compact transient voltage suppression diode packaged in the SOD-123FL form factor, specifically designed for low-voltage electronic circuit protection. The device features a 7.5V reverse working voltage (VRWM), a minimum breakdown voltage (VBR min) of 8.33V, and a maximum clamping voltage (VC) of just 12.9V, with reverse leakage current (IR) controlled below 50μA. These precise parameters make it an ideal protection solution for 5V and 3.3V low-voltage systems.

The rapid response time is the core competitive advantage of the SMF7.5A. The device adopts Slkor's proprietary avalanche breakdown technology, with a response time of less than 1 nanosecond. It effectively protects against transient interferences such as ESD (Electrostatic Discharge) according to IEC 61000-4-2 Level 4, and EFT (Electrical Fast Transient) pulses per IEC 61000-4-4. At the SEMICON China exhibition, Slkor engineers demonstrated in real-time how the SMF7.5A could precisely limit transient high voltage on a 7.5V line to below 12.9V under an 8/20μs standard lightning strike test waveform, earning recognition from many professional visitors for its protective performance.

Parameters of Slkor Transient Protection Diode SMF7.5A

Compared to the previous generation, the SMF7.5A has achieved breakthroughs in three key areas: a lower clamping voltage (reduced by approximately 15%), more stable temperature characteristics (VBR fluctuation under -40°C to 125°C is less than 5%), and higher reliability (passing over 1000 ESD impact tests). These improvements make the device particularly suitable for voltage-sensitive low-power IoT devices and portable electronics.

Application Scenarios: From Consumer Electronics to Automotive Electronics

At SEMICON China, Slkor showcased the SMF7.5A’s application solutions across multiple emerging sectors. Wearable devices such as TWS (True Wireless Stereo) earbuds are a key application area for the SMF7.5A. These products typically use 5V power for charging cases, with extremely limited space. The compact SOD-123FL package (measuring just 2.5mm × 1.8mm × 1.1mm) and low leakage current characteristics of the SMF7.5A perfectly meet these demands, and several well-known audio manufacturers have already adopted this device in their latest designs.

The smart home sector also presents significant potential. With the growing popularity of the Matter protocol, smart home devices require more reliable circuit protection to ensure stable interconnectivity. Slkor demonstrated the SMF7.5A’s application in Zigbee and Thread modules, where the device not only provides effective protection against electrostatic discharge but also ensures that wireless signal transmission quality remains unaffected due to its low capacitance characteristics (typical value of 50pF).

A noteworthy application is in automotive electronics. As automotive electronics become more advanced, the demand for low-voltage circuit protection in in-vehicle infotainment systems and ADAS (Advanced Driver Assistance Systems) sensors is rapidly increasing.

Industry Chain Synergy: Opportunities Brought by SEMICON China

SEMICON China 2025 is not only a platform for showcasing but also offers deep collaboration opportunities for upstream and downstream enterprises within the industry chain. The advanced packaging technologies displayed at SEMICON China have also inspired Slkor.

Domestic Substitution Accelerates: Breakthroughs in Technology and Market

From SEMICON China 2025, it is evident that China’s semiconductor industry is shifting from "catching up" to "keeping pace" and even "leading." The emergence of domestically developed innovative products like the SMF7.5A not only fills domestic technological gaps but also makes a strong "Chinese voice" in the global semiconductor landscape.
