MSV101A thru MSV101G MSV201A thru MSV701A BIDIRECTIONAL VARISTORS SCOTTSDALE DIVISION APPEARANCE The MSV series consists of a matched set of silicon p-n junctions configured for bidirectional application. They can be used in telephone equipment, replacing copper-oxide varistors, fractional voltage regulators, negative-temperature-coefficient resistors, signal limiters and expanders. They are ideally suited for meter/galvanometer protection, wave shaping, threshold limiters and zener diode compensation. The MSV varistor uses two or more forward biased matched silicon diodes in anti-parallel legs in a two-electrode device configuration. It provides a voltage-dependent nonlinear resistance that drops markedly as the applied voltage is increased similar to a TVS except it offers lower voltage features. MSV devices are designed for controlled protection at various current levels and are rated at various peak pulse currents. These varistors are supplied in Microsemi's cost-effective, highly reliable, molded axial-leaded package. Non-standard voltages are also available. Devices in this series with VC2 clamping are rated to U.L.497B requirements. (See table). WWW .
