SERIES N
HIGH VOLTAGE MULTIPLE SILICON PACKAGES
Edal’s multi-unit package offers many optional configurations in one standard modular design. A sharp
reduction in space requirements, simplified purchasing, reduced inventory, fewer lead connections and faster
assembly by eliminating the need of soldering many diodes to achieve equivalent circuitry are substantial
advantages. Each modular package consists of matched, pre-tested, pre-selected, and double diffused bulk
avalanche rectifiers offering self-protection against voltage transients. Low unit cost and increased reliability are
proven results of Edal multiple circuits. They are now available in full wave, half wave, doubler, center tap,
open bridge, three phase types and fast recovery from 500 to 50 ns.
