In the microscopic world of electronic devices, each component plays an indispensable role, collectively weaving a precise network that drives modern technology. The Transient Voltage Suppression (TVS) diode SMCJ78CA, a high-performance electronic protection element, plays a critical role in circuit protection due to its unique bidirectional conductivity and precise voltage control capabilities. Meanwhile, a recent announcement from Shanghai Silicon Industry (stock code: 688126) has drawn widespread attention in the industry. The semiconductor leader is further strengthening its core position in the supply chain through a series of strategic initiatives.

The SMCJ78CA, with its 78V reverse working voltage (Vrwm), provides reliable overvoltage protection for circuit design. Under normal operating conditions, it effectively prevents excessive voltage from damaging the circuit, ensuring stable operation. When the circuit encounters sudden voltage spikes, the bidirectional conductivity of the SMCJ78CA allows it to quickly respond, directing excess voltage to ground, thereby protecting other sensitive components in the circuit from damage. With a breakdown voltage range of 86.7V to 95.8V, its precise voltage control capabilities have made it widely used in automotive electronics, telecommunications equipment, consumer electronics, and various other fields.

Notably, the SMCJ78CA boasts a peak pulse current capability of 11.9A (under 10/1000μs waveform conditions), meaning it can quickly absorb and dissipate energy when exposed to short bursts of strong current, preventing damage to the circuit due to overheating or overloading. Furthermore, its maximum clamping voltage is 126V, ensuring that even in breakdown conditions, the voltage remains within a safe range, further enhancing circuit safety and reliability. These outstanding performance parameters make the SMCJ78CA a shining gem in the field of circuit protection.

However, in today’s rapidly advancing technology landscape, the exceptional performance of a single product is not enough to sustain a company’s long-term growth. Shanghai Silicon Industry understands this well, which is why, in addition to continuously improving product performance, it is also actively seeking collaborative development throughout the supply chain. On the evening of February 12, Shanghai Silicon Industry announced that its subsidiaries, Shanghai Xinxing and its controlling subsidiaries Xinxing Jingrui and Jinke Silicon Materials, plan to sign an electronic-grade polysilicon procurement framework agreement with Jiangsu Xinhua Semiconductor Technology Co., Ltd. ("Xinhua Semiconductor"), with a total contract value expected to be 1.054 billion yuan (including tax).

This move not only highlights Shanghai Silicon Industry’s strategic foresight in supply chain layout but also demonstrates its full recognition of the quality of domestic electronic-grade polysilicon. As one of the core raw materials in semiconductor manufacturing, the purity and quality of electronic-grade polysilicon directly impact the performance and reliability of chips. The collaboration between Shanghai Silicon Industry and Xinhua Semiconductor is undoubtedly an important endorsement of the quality of domestic electronic-grade polysilicon and a deep practice of collaborative development in the semiconductor supply chain.

In the context of increasing global competition in the semiconductor industry, mastering the ability to independently control key raw materials has become an important indicator of a country’s comprehensive strength in the semiconductor sector. This strategic decision by Shanghai Silicon Industry not only provides strong raw material support for its continued innovation in semiconductor devices but also injects powerful momentum into the autonomous and controllable development of China’s semiconductor industry.

Looking ahead, both the wide application of the SMCJ78CA in circuit protection and Shanghai Silicon Industry’s far-reaching supply chain strategy will jointly drive the continuous and healthy development of the semiconductor industry. In the wave of technological innovation, every small advancement may become a key force in driving industry transformation. The story of Shanghai Silicon Industry and the SMCJ78CA is a vivid portrayal of this concept.
