1. Schottky diode
1.1 Small signal Schottky diode
This series of products is less than 1A Schottky diode, used to control signals or rectifier products.
The series is a product that is higher than 1A (with 1A) Schottky diodes and is applied to power supply switching and rectification. With extremely low reverse leakage current and reduced power consumption. And has a high withstand voltage and a significant improvement in the quality reliability. The very low IR characteristic is used in the high-temperature environment of the power supply, so as to effectively avoid the heat run.
1.3 Super low voltage drop Schottky diode
This series is a Schottky diode with extremely low forward voltage drop and reverse leakage current, and is suitable for small packages with low power consumption and high current. The application of this Schottky conforms to the end customer's Energy Star specification.
2. Commutation diode
2.1 Small signal rectifier diode
This series has the characteristics of ultra-fast TRR and low CJ, so it is suitable for rectifier lines at the signal end.
The VRMs of this series of products are 50V ~ 2000V, IO = 0.2A ~ 8A, and it is applied to the application of bridge rectifier and VCC Rectifier.
2.3 Fast recovery / ultra fast recovery / very fast recovery diode
The VRRM=50V~1300V,IO=1A~30A,TRR=25ns~500ns, of this series of products is generally used in Snubber line / VCC rectifier and other application lines.
This series of products can be divided into Schottky bridge rectifier (VRRM=40V~100V) and general bridge rectifier (VRRM=50V~1200V). It is generally used in AC/DC rectifier.
This series of products, from 2 Pin single to multi-pin integrated products, has complete and complete specifications.
5. Protective device (TVS/ESD)
This series of protection components adopts their own wafer and packaging technology to develop a product line with excellent instantaneous voltage suppression and high reliability.
This series has a variety of different packaging low-voltage MOSFET products, BVDSS 20V~50V is suitable for notebook computers, tablet computers, motherboards and other 3C products will be used in this type of products; Combined with grooving (Trench) structure and packaging technology, the performance of the product can be improved by low on resistance.
This series of medium voltage products BVDSS 60V ≤ 200V, trench (Trench) structure design to improve product characteristics; often used in synchronous rectifier circuits, can be used in consumer products and other electronic power supplies, communication power systems and so on.
In addition to using advanced process high efficiency cell density design, this series of products have lower conduction loss and switching loss. BVDSS 400 / 1000V can be used in AC and DC power supplies such as chargers, household appliances, industrial equipment and various LED lighting equipment. In addition, in order to ensure product performance, 100% test is carried out according to Avalanche Energy characteristics to ensure product quality.
