For bidirectional type having VR of 10 volts and less, the IR limit is double. For parts without A , the VBR is ± 10% and Vc is 5% higher than with A parts, the parts without A are currently available, but not recommended for new designs. The parts with A are preferred. © 2020 Littelfuse, Inc. Specifications are subject to change without notice.
