High-voltage systems in new-energy vehicles, such as on-board chargers and motor controllers, face stringent requirements for efficiency and reliability. Carbonization Silicon Carbide (SiC)–Based Schottky Chip Thanks to its high-pressure and high-temperature resistance, it has become the mainstream solution.

Photovoltaic systems must convert unstable solar energy into stable electrical power, and the high-frequency response and low-loss characteristics of Schottky diodes directly determine the system’s conversion efficiency.

Example: Photovoltaic inverters—within the DC‑AC conversion stage of an inverter, Schottky diodes exhibit a reverse recovery time approaching 0 ns, enabling them to readily handle high‑frequency operating conditions above 100 kHz. In this application, 1200 V SiC Schottky diodes reduce power losses by 70% compared with silicon devices, making them the standard choice for commercial photovoltaic power plants.

Industrial inverters, servo drives, and other equipment demand exceptionally high energy efficiency and reliability; the wide-temperature operating range and low-loss characteristics of Schottky chips can directly reduce enterprises’ operating costs.

Industrial communication equipment: High-frequency signal “transmission‑link” level switching power supplies must withstand high‑temperature, dusty environments. SiC Schottky diodes can operate reliably at 175°C to 200°C, with thermal resistance reduced by 50% compared to silicon devices. The Heketai MBR1060 model maintains a reverse leakage current of less than 10 μA even at a junction temperature of 150°C, ensuring stable power supply in harsh industrial settings such as metallurgy and chemical processing.

5G base stations and RF circuits impose stringent requirements on signal-processing speed, making the high-frequency response characteristics of Schottky diodes a critical enabler for signal transmission.

RF Detectors and Mixers: In the RF circuits of radar and satellite communications, Schottky diodes leverage their ultra‑fast switching speed to enable signal detection and frequency conversion. For instance, when incorporated into the microwave receiver module of weather radars, these devices can accurately capture faint echo signals, improving detection accuracy by 30%.

With the advancement of wide-bandgap semiconductor technology, Schottky devices are expanding into higher-voltage applications and cutting-edge domains—such as smart grids, sensors, and optoelectronics.
