Insel Rectifiers [India] Pvt. Ltd. Offers Step-recovery Silicon Diodes. Insel Rectifiers [India] Pvt. Ltd. Supplies different rectifiers like selenium, silicon diodes, thyristors, bridge rectifiers, modules, transformers, missile cables etc. Step-recovery Silicon Diodes produces an abrupt turn-off time by allowing a very fast release of stored charge when switching from forward to reverse bias. Step-recovery Silicon Diodes also allows a rapid re-establishment of forward current when switching from reverse to forward bias.Ÿ These diodes are used in very high frequency [VHF] and fast switching applications. These are the electronic components that conduct current in only one direction. In function, they are similar to one-way valves. These diodes are manufactured using semiconductor materials such as silicon, germanium or selenium and are used as voltage regulators, signal rectifiers, oscillators and signal modulators / demodulators. Diodes can be used as voltage regulators, tuning devices in RF tuned circuits, frequency multiplying devices in RF circuits, mixers in RF circuits, switching applications, or can be used to make logic decisions in digital circuits.
