Rugged MOSFETs from Diodes handle the rigours of VoIP communication equipment
Diodes incorporated has extended its MOSFET product line with the introduction of 60V N-channel devices tailored for use in VoIP communication equipment. Designed to handle the high pulse current needed to generate tip and ring linefeeds and to withstand the avalanche energy induced during switching, the DMN60xx series meets the stringent requirements of the primary switch position in transformer based Subscriber Line Interface Circuits (SLIC) DC/DC converters.
DiodThe MOSFETs' low gate charge and input capacitance mean that they can be driven with minimal or no buffering at low logic level voltages, so simplifying SLIC circuit design and further reducing component count and cost. Device gate charge and on-resistance performance have been balanced to deliver the requisite figure of merit for VoIP applications, including cable and DSL modems, analog terminal adaptors and private branch exchanges.
