Siliconix Unveils 14 New PowerPAK MOSFETs

Siliconix Inc. (Santa Clara, CA), a subsidiary of Vishay Intertechnology Inc. (Malvern, PA), introduced 14 PowerPAK power MOSFETs, featuring improved package technology that yields lower on-resistance devices. The new PowerPAK devices provide on-resistance, gate-charge and on-resistance-times-gate-charge values optimized for synchronous, low-side operation and/or high-side, control operation in core-voltage, dc/dc buck converters, and for secondary-side, synchronous rectifiers in isolated dc/dc converters.

The devices are designed for use in single-phase or multi-phase power supply circuits in server and desktop computer applications, notebook computer applications requiring 30V devices, and in dc/dc converters and point-of-load converters in fixed telecom applications. For low-side, dc/dc applications in computers, the 20VDS/20VGS Si7866DP and 30VDS/12VGS Si7442DP offer on-resistance values of just 3.75 milliohms and 3.2 milliohms. The new 30VDS/20VGS Si7880DP features a low on-resistance of just 4.25 milliohms. For power conversion applications in computers, the 30VDS/20VGS Si7860DP offers low on-resistance-times-gate-charge of just 143, and a low gate charge of just 8.5nC. For fixed telecom applications, the Si7368DP, Si7366DP, Si7864DP, Si7860DP and Si7884DP are optimized for high switching frequencies.

Samples and production quantities of the new PowerPAK devices are available now with lead times of 8 to 10 weeks for larger orders. Pricing for US delivery in 100,000-piece quantities ranges from $0.82 to $1.93.
