Features
The MSV saries consists of a matched set of silicon junctions configured for bidirectional application. They can be used in telephone equipment, replacing: copper oxide varistors, fractional voltage regulators, negative temperature BIDIRECTIONAL coefficient resistors, signal limiters and expanders. They are ideally suited for: meter/galvanometer protection, wave shaping, threshold limiters and zener VARISTORS diode compensation. The MSV varistor uses two anti-parallel, matched, silicon diodes in a two- SCHEMATIC electrode device configuration with a voltage-dependent nonlinear resistance fe that drops markedly as the applied voltage is increased. 7 MSV devices are designed for controlled protection at various current levels and y are rated at various peak pulse currents. | These varistors are supplied in Microsemi’s cost-effective, highly reliable, molded PACKAGE DIMENSIONS axial leaded package. Non-standard voltages are available. Devices in this series with V2 clamping are rated to U.L.497B requirements.
