Our company recently wrapped up participation in Shanghai Electronica, showcasing our core power semiconductor lineup: advanced thermal surface-mount packaging solutions, SCR thyristors, silicon carbide (SiC) devices, TVS protection components, and integrated power modules.

Against current industry headwinds of surging raw material costs and prolonged component lead times, we held extensive technical exchanges with global buyers. The booming AI server infrastructure sector stood out as a key growth driver, pushing higher demand for high-efficiency, high-reliability power and thermal management products.

Our differentiated SiC portfolio and optimized heat dissipation packaging drew strong customer interest, as clients seek cost-effective, supply-stable alternatives to ease supply chain pressure. We secured multiple potential cooperation leads covering data center, industrial control and new energy segments.

Moving forward, we will accelerate production capacity layout and thermal technology iteration to address tight delivery cycles, while rolling out customized power device solutions tailored for AI server high-power supply systems to capture emerging market opportunities.

Key Discrete Semiconductors for Inverter & Power Management Designs

When optimizing inverters, UPS systems, or power management circuits, selecting the right diodes and transistors makes all the difference in efficiency, protection, and reliability. Below are four critical components that often appear in robust power electronics designs:

🔹 UMD3N – A dual NPN/PNP digital transistor (pre-biased) ideal for signal switching, level shifting, and low-power driving in compact inverter control stages.

🔹 SMCJ70CA – A 70V bidirectional TVS diode (DO-214AB) providing transient overvoltage protection. Essential for safeguarding inverters against voltage spikes and surge events.

🔹 BD682 – A PNP Darlington transistor (high current gain) suitable for medium-power linear/switching applications, often used in pre-driver or actuator circuits within power systems.

🔹 BAS70-06 – A dual Schottky barrier diode (common cathode, 70V/70mA) delivering ultra-fast switching and low forward voltage drop, perfect for high-frequency rectification, clamping, or OR-ing diodes in DC-DC converters.

Whether you’re designing solar inverters, battery chargers, or industrial power supplies, these components help balance cost, thermal performance, and electrical robustness.

💡 Pro tip: Pairing the TVS (SMCJ70CA) with Schottky diodes (BAS70-06) near switching nodes can drastically improve EMI and surge immunity.

Have you used any of these in your latest power design? Let’s discuss below! 👇

【High‑reliability discrete semiconductor solution for T‑BOX and telematics products】

In T‑BOX (telematics control unit) and other network communication designs, small‑signal switching, logic control, and protection circuits demand high stability and fast response.

We are offering a proven combination of bipolar transistors and a switching diode for these applications:

🔹 S9012 – PNP small‑signal transistor, ideal for low‑power switching and amplification
🔹 S9013 – NPN small‑signal transistor, complementary to S9012 for flexible logic control
🔹 1N4148W – high‑speed switching diode, fast reverse recovery, suitable for signal clamping and freewheeling protection

All devices come in surface‑mount packages (SOT‑23, etc.), making them perfect for high‑density PCB layouts in T‑BOX. They also support a wide operating temperature range, meeting the stringent requirements of automotive and industrial telematics equipment.

If you are optimizing your BOM for T‑BOX, gateways, or similar communication modules, feel free to reach out for selection advice and sample support.
