r bridge How to replace ABS packages such as ABS2, ABS4, ABS6 and other rectifier bridges?

Rectifier bridge model replacement: Regarding the replacement of ABS2, ABS4, ABS6, rectifier bridge ABS2, ABS4, ABS6 from the electrical parameters, ABS2 electrical parameters are 1A200V, ABS4 is 1A400V, ABS6 electrical parameters are 1A600V, therefore, according to their different voltage resistance, ABS4 can replace ABS2, ABS2 can not replace ABS4; ABS6 can replace ABS4 and ABS2, but ABS2 and ABS4 cannot replace ABS6. Such a complex relationship is actually because these are uncommon SMD rectifier bridge models, and they generally choose a large margin of rectifier bridge models to ensure that a large safety margin is maintained during the power-on process to prevent explosion.

In short, the rectifier bridge replacement principle mainly looks at the electrical parameters of the rectifier https://www.yfwmos.com/2.htmlbridge, the large electrical parameters can replace the small, otherwise, it cannot! Not only rectifier bridges, but also many common diode replacements need to follow this principle, please refer to the product data sheet for details.
