The new rectifier USES only 50 mg, 1 mm thick SMBFlat encapsulation, than its nearest rival products car 2.4 mm thick SMB encapsulation thinner nearly 60%. Thin appearance can help designers develop more frivolous and suitable for installation in automobile Electronic controller unit within the narrow space (ECU, Electronic Control Units). Double lead surface-mount (settlement - lead surface - mount) SMBFlat encapsulation compatible with standard SMB device, convenient in the existing printed circuit boards using new rectifier.
To 40 ° C to 175 ° C temperature range make stmicroelectronics SMBFlat rectifier especially suitable for automobile application and operation of a variety of applications in the bad environment, such as mobile communication base stations and outdoor lighting (is suing lighting).
To date, stmicroelectronics product launched 10 ultra-high speed rectifier tube, rated current 1 a and 3 a, repetitive peak reverse voltage (repetitive peak reverse voltage) rating from 600 v to 1200 v. The product family was divided into two series L and R, L series low forward voltage (VF, forward voltage) is suitable for the need to the design of the low state loss; And R series reverse recovery time (TRR, reverse recovery time) is shorter. Reverse recovery speed can reduce the switching loss big degree, improve the high frequency switch operation efficiency, use smaller external inductor and capacitor.
