Zener and Avalanche Regulator Diodes In every language under the sun, the name most commonly associated with solid-state regulator and reference devices is Motorola. A pioneer in Zener diodes development, Motorola has consistently led the industry in parameter improvements, packaging proliferation and specifications innovation. Today, Motorola serves the industry with an incomparable line of zener and avalanche regulator diodes, temperature compensated reference devices, and a host of integrated circuits designed to provide the exact degree of regulation required, at the point in the circuit or system where it can be used most conveniently at the lowest cost. Plastic All Motorola Zener diodes are made with the oxide passivated process for the utmost in reliability. Zener diodes are available also in matched pairs, clippers and at special voltages and tolerances. Motorola has the largest availability to military specifications (Jan, Jantx and Jantx V).
