Activating idle inventory: Mingjiada reclaims all ST diodes and rectifiers at a high price

Source:our siteTime:2025-08-18Views:

Amid the wave of explosive growth in electric vehicle drive systems, industrial power supply upgrades, and photovoltaic energy storage, ST (STMicroelectronics) diodes and rectifiers, as the "precision gates" for power control, directly affect system efficiency and reliability in terms of performance. However, technological iterations, production line switches or order changes often result in a large number of brand-new original ST components being stranded in the warehouse, becoming "silent assets" in the enterprise's capital chain. Shenzhen Mingjiada Electronics Co., LTD., with 15 years of accumulation in automotive electronics recycling technology and a terminal channel network worth hundreds of billions of yuan, has launched a special high-price recycling plan for ST diodes and rectifiers - through scientific pricing, rapid payment recovery and green regeneration, we help you transform idle components into competitive capital!

The key categories that Mingjiada focuses on recycling

Automotive-grade diodes

STMicroelectronics' automotive diode product series has passed the AEC-Q101 standard certification and is applied in DC-DC converters, which can be used to achieve various automotive functions. Most of these dedicated diodes can ensure operation at junction temperatures as low as -40 °C and as high as +175 °C. Automotive-grade diodes belong to our STPOWER series.

2. Bridge rectifier diode

Bridge rectifier diodes are typically used at the front end of many power conversion systems. ST's diodes have a very high reverse voltage of 1200 V and a peak voltage of 1500 V, which can handle non-repetitive transient voltages and ensure that the power converter can operate under most grid power supply conditions.

3. Field-effect rectifier

This type of rectifier enhances the performance of Schottky diodes through a lower current density. It has a low threshold voltage and power loss, and can meet the requirements even under light load operation. The voltage range of FERD is 45V to 100V, and it is usually used in flyback Topchargers.

4. Ultra-high-speed rectifier

As converters shifted from hard mode to critical mode, such diodes were fully developed. The softness has been continuously improved with the launch of the AC and RQ series.

5. Silicon carbide diode

650 to 1200 V devices, featuring unlimited recovery loss, low voltage drop and beneficial surge performance. Its heat transfer capacity is much higher than that of traditional silicon materials.

6. Schottky barrier diode

STMicroelectronics' Schottky diodes feature a low forward voltage drop and negligible reverse recovery charge, ensuring higher switching speeds and system efficiency within the voltage range of 15V to 200V. They adopt technology with stable avalanche characteristics and are available in both industrial and automotive grades.
