The IGBT tube is the core component of the portable emergency energy storage power supply. What part of the problem should the portable emergency energy storage power supply focus on to adopt IGBT tube factories that have suitable IGBT tubes for portable emergency energy storage power supplies? At present, in the IGBT tube market, the defects of low-quality IGBT tubes involve electromagnetic interference, poor heat dissipation, and efficiency reduction. These defects not only severely suppress the normal operation of portable emergency energy storage power equipment but also increase maintenance costs. Therefore, it is very important to pursue high-end quality replacement model IGBT tube products. When electronic technicians of portable emergency energy storage power supplies replace the FGH40N60SFD IGBT tube, they need to pay attention to many important conditions. For example, the performance parameters of the IGBT tube: whether the rated current reaches 40A, whether the rated voltage reaches 600V, etc., all are closely related to the device's work efficiency. Furthermore, the packaging type and gate threshold voltage (VGE(th)) are also indispensable matters. In the selection of many global portable emergency energy storage power supply manufacturers, FHA40T65A has already replaced FGH40N60SFD and can be widely used. We recommend you carefully check its detailed product specifications: 1. Low switching loss 2. Circuit voltage of 40A and 600V 3. VCEsat typical value: 1.51V, <1.85V 4. Trench gate field stop type IGBT 5. Possessing a fast recovery diode in parallel Customers highly recognize the FHA40T65A IGBT tube model, making it a popular IGBT tube star product! Therefore, Feihong Semiconductor strongly recommends using the FHA40T65A IGBT tube model to increase the power switch capability of portable emergency energy storage power supply circuits. The 40A and 600V IGBT tube indeed solves the problems of electromagnetic interference, poor heat dissipation, and efficiency reduction. Feihong Semiconductor's approach to providing IGBT tubes to portable emergency energy storage power supply manufacturers is refreshing, and the spirit is honest business. It will continue to purchase the FHA40T65A IGBT tube model in the long term. For more details, you can search "Feihong Semiconductor" on Baidu or call the free trial hotline: 400-831-6077!
