Vishay Intertechnology, Inc. launched two new IGBT and MOSFET drivers in the compact, excessive isolation stretched SO-6 bundle. Delivering excessive peak output currents of three A and 4 A, respectively, the Vishay Semiconductors VOFD341A and VOFD343A provide excessive working temperatures to +125 °C and low propagation delay of 200 ns most.
Consisting of an AlGaAs LED optically coupled to an built-in circuit with an influence output stage, the optocouplers launched right this moment are supposed for photo voltaic inverters and microinverters; AC and brushless DC industrial motor management inverters; and inverter phases for AC/DC conversion in UPS. The gadgets are ideally suited to straight driving IGBTs with scores as much as 1200 V / 100 A.
The excessive working temperature of the VOFD341A and VOFD343A supplies the next temperature security margin for extra compact designs, whereas their excessive peak output present permits for quicker switching by eliminating the necessity for a further driver stage. The gadgets’ low propagation delay minimizes switching losses whereas facilitating extra exact PWM regulation.
The optocouplers’ excessive isolation bundle allows excessive working voltages as much as 1.140 V, which permits for prime voltage inverter phases whereas nonetheless sustaining sufficient voltage security margin. The RoHS-compliant gadgets provide excessive noise immunity of fifty kV/µs, which prevents fail features in quick switching energy phases.
Samples and manufacturing portions of the VOFD341A and VOFD343A can be found now, with lead instances of six weeks.
